Proper Maintenance Procedures for Excavators
Ken Thayer | December 12, 2017

Excavators are heavy construction equipment with a bucket on the end of a jointed boom and a rotating cab referred to as the “house,” located on top of an undercarriage containing tracks or wheels. Designed for digging earth, loading material onto trucks and digging trenches, they are subjected to harsh conditions, often operating in the rain, hot sun, snow or mud. Just like an automobile, truck or any other piece of construction equipment, proper routine maintenance is critical to keeping them in good working order.

Proper maintenance maximizes fuel efficiency and reduces operating costs as well as equipment failure. Every minute an excavator or other heavy equipment is offline due to a breakdown costs the operator money in wages and lost productivity. Scheduled maintenance can help contain these expenses and maximize productivity.

An important part of all construction equipment maintenance is proper recordkeeping. Keeping this information up-to-date will help when evaluating the service life of the machine. Accurate records will also help prove that the machine has been properly serviced if the need to discuss issues with a dealer or manufacturer arises.

Daily Inspection Checklist

Take the time to perform a daily walk-around inspection before operating the excavator. The inspection does not require much time and can easily pay for itself if an issue is discovered.

The following items should be checked prior to operation:

Check to make sure there is enough coolant
Check engine oil and hydraulic oil levels
Check for leaks in compartments and under machine
Check track (see Undercarriage below for more detailed information)
Check coolers to make sure they are free of debris
Drain water from fuel/water separator
Check dust ejector from air filter
Make sure teeth are present on bucket and they are in good condition
Check wear plates on bucket
Grease all pins and bushings daily
Check controls and seat belt in cab and make sure they are operating properly
Turn on machine and check controls, windshield wipers, seatbelt and air conditioning system
Remove trash and debris from cab
Undercarriage

The undercarriage is an expensive part of owning and operating an excavator. When operating the machine, always work and dig over the idler, as opposed to the side or back of the excavator, and operate the machine in the forward direction as much as possible to avoid excess wear. If the excavator needs to sit for extended period of time, start the machine every few months and exercise the track to avoid pins seizing.

The following items should be inspected to ensure proper track operation:

Look for loose bolts on track and tighten if necessary.
Look for bent shoes on tracks. The shoes support each other and one bent shoe can lead to additional bent shoes.
Replace bent or damaged guards and guides on bottom of track (“rock guides”).
Inspect sprocket and drive at rear of track for oil leaks and to make sure all bolts are present and tight.
Clean out debris from around track and adjust track tension if necessary to avoid excess wear (Note: Do not run tracks too tight — refer to maintenance manual for proper tension.)
Make sure cotter pins in the master link are present.
The propel gearbox is frequently overlooked but is a vital component of machine performance. Gearbox oil should be changed at approximately 1,000-hour intervals, depending on the excavator manufacturer.

Changing Air and Fuel Filters

Proper maintenance of air, fuel and hydraulic filters is an important maintenance requirement for equipment operating in dirty and wet conditions. Refer to the operator manual and follow the instructions carefully when changing air or fuel filters. Shortcuts are a common cause of contamination and problems.

Hydraulic oil is filtered on return to the tank and not the pressure side. To check or clean the hydraulic oil filter, release the pressure to the tank by loosening the cap. Clean the oil filter cap to prevent dirt and debris falling into the filter; remove the filter cap and then clean away any dirt from the top of the filter. Remove the filter and clean if necessary, making sure to follow the instructions carefully. Finally, reassemble, inspecting O-rings and components for damage and dirt.

Swing Bearing and Swing Gear Maintenance

The swing gear is a vital component and is often neglected when servicing the excavator. Both the bearing and the gear should have proper lubrication and be free from contamination. Make sure bearing is greased properly and inspect the swing gear to make sure enough grease is present and water or dirt hasn’t leaked into the compartment.

Spark Plugs

When checking or changing the spark plugs, make sure to clean and re-gap spark them. Do not forget to clean the threads and seat area and change the gasket before reinstalling the spark plug. Also, it is important to use proper torque when reinstalling spark plugs (refer to operator manual).

Low Power Troubleshooting

When troubleshooting a perceived low power issue, start with the simple things first. Look at the air filters and fuel filters for restrictions, such as leaves, and remove or clean if necessary. Measure the actual cycle times and compare to the specified service times in the service manual. This will determine whether there is an actual problem or a perceived issue. A valve adjustment may be required, but this is a more complex issue and may need to be performed by the dealer.

Following these maintenance procedures and keeping proper records will help reduce operating and unscheduled maintenance costs and keep your excavator in peak running condition.

There’s been a solar eclipse (warning to the Gentiles) on Wednesday, 9 March and a soon coming lunar eclipse (warning to Israel) next Wednesday, 23 March. Also, rather unexpectedly, President Putin removed Russian military from Syria on the Ides of March (15 March – meaning beware the day, as stated to Julius Caesar in his time. He was assassinated on the Roman equivalent of this day). Concerning these "warnings" nothing much has appeared to happen so far although an increasing momentum is building up. Indeed, nothing much appears to have happened with the four seals we have had so far. SEAL ONE: (28 September, ) Marked the start of 40-week gestation period (as Pope Francis left America) which will culminate in the birth of the New World Order (Beast Kingdom) on Monday, 4 July at the Seventh Seal. SEAL TWO: World War III which might have started "in the heavenlies" after First Seal started in Paris with the terror attacks there. SEAL THREE: (30 December, ) Saw the start of worldwide economic collapse. Stock markets started to fall on this day and have continued (slowly) . Prices of commodities have fluctuated wildly usually dropping in price. SEAL FOUR: (15 February, ) Emphasised the beginning of first Gog & Magog War. Syria was attacked by Turkey – still ongoing. Escalation in the troops on the ground has increased. ‘Soldiers from 20 countries will be gathering in Saudi Arabia for massive military exercises’, was in the news.

Here’s a few Scriptures to start us up.
(Jeremiah 51:53.) "Even if Babylon ascends to the heavens and fortifies her lofty stronghold, I will send destroyers against her,” declares the LORD." (Isaiah 14:14.) "I will ascend above the tops of the clouds; I will make myself like the Most High.” Isn’t this talking about space travel and flying? Sounds like America.

They are different from other nations; awe-inspiring from birth; first to successfully become independent from colonial empire. (Isaiah 18:2.) "..which sends envoys by sea in papyrus boats over the water. Go, swift messengers, to a people tall and smooth-skinned, to a people feared far and wide, an aggressive nation of strange speech, whose land is divided by rivers." (Jeremiah 50:12.) "Your mother will be greatly ashamed; she who gave you birth will be disgraced."

Mother of Babylon has symbol of lion. (Jeremiah 51:38.) "Her people all roar like young lions, they growl like lion cubs." UK has the symbol of a lion. Doesn’t this description fit America perfectly too?

She is "Queen among Nations" & "the Lady of Kingdoms." (Isaiah 47:5,7.) “Sit in silence, go into darkness, queen city of the Babylonians; no more will you be called Queen of Kingdoms." You said, ‘I am forever— the Eternal Queen!’ But you did not consider these things or reflect on what might happen."
Also known as daughter of Chaldea. This is a reference to the area in the Middle East where Israelis and Jews lived. 48% of American billionaires are Jewish. So the Jewish people raised them to greatness.

Ancient Babylon saw people come from all parts of the known world. Likewise today,
Mystery Babylon (or America) is seen as a woman. So what symbol does she depict? The Statue of Liberty. From which comes the name, Whore of Babylon? This statue is a depiction of the goddess of fertility – Isis; also Ishtar and Libertas according to which country and language.

There’s a few clues beginning to appear here to her demise. (Revelation 18:3.) "For all the nations have drunk the maddening wine of her adulteries. The kings of the earth committed adultery with her, and the merchants of the earth grew rich from her excessive luxuries.”

Mystery Babylon or America becomes a democracy weighed down by huge government. (Isaiah 47:13.) "All the counsel you have received has only worn you out! Let your astrologers come forward, those stargazers who make predictions month by month, let them save you from what is coming upon you."

She also destroys her own country with pollution and waste. (Isaiah 14:20.) "You will not join them in burial, for you have destroyed your land and killed your people. Let the offspring of the wicked never be mentioned again." How would an ancient prophet know about pollution? The clue is in this Jeremiah prophecy. (Chapter 50:23.) "How broken and shattered is the hammer of the whole earth! How desolate is Babylon among the nations!" It is in her military.

How is the praise of the whole world surprised? (Jeremiah 51:47-48.) "For the time will surely come when I will punish the idols of Babylon; her whole land will be disgraced and her slain will all lie fallen within her. Then Heaven and Earth and all that is in them will shout for joy over Babylon, for out of the north destroyers will attack her,” declares the LORD." As shown in verse 48, Babylon becomes proud and arrogant not seeing its end. (Isaiah 17:9-10.) "In that day their strong cities, which they left because of the Israelites, will be like places abandoned to thickets and undergrowth. And all will be desolation. You have forgotten God your Saviour; you have not remembered the Rock, your Fortress."

So what will cause her fall, when and how? We’ve already mentioned Russia and President Putin. This person and nation will bring about the fall of America. (Revelation 18:8.) "Therefore in one day her plagues will overtake her: death, mourning and famine. She will be consumed by fire, for mighty is the LORD God who judges her." Also, (Jeremiah 51:8-9.) "Babylon will suddenly fall and be broken. Wail over her! Get balm for her pain; perhaps she can be healed. We would have healed Babylon, but she cannot be healed; let us leave her and each go to our own land, for her judgment reaches to the skies, it rises as high as the heavens." Nothing like this in ancient times ever happened to Babylon (now modern day Iraq). It doesn’t fit the description.

Biden is the king of the South. Born in usa South of Jerusalem. Likewise, Putin who was born in Moscow is the King of the North.

How does it start? (Daniel 11:40.) “At the time of the end the King of the South will engage him in battle, and the King of the North will storm out against him with chariots and cavalry and a great fleet of ships. He will invade many countries and sweep through them like a flood." Biden pushed at Putin as far back as 2011. First it was Syria, then Ukraine. More recently through economic sanctions and doing a deal with Saudi Arabia to reduce price of oil from $100 down to $40 so as to hurt Russia’s economy.

As things stand, towards end of March they America & Russia, haven’t met each other head on but will do. This is sometime because biden leaves office after presidential election at the end of the year 2024. My best guess is that an economic downtown in Russia will force President Putin’s hand. The people will demand he do something about the economy. This will leave him with few options. He will have to strike. As described in last Scripture, they will not be able to hide such a large military operation. That is in clear view now building up with actions in different countries and military drills. (Isaiah 13:5.) "They are coming from a distant country, from the end of heaven [the farthest horizon]–The LORD and the weapons of His indignation— to destroy the whole land.’

What is this? There’s another clue in a Scripture already used. (Isaiah 47:5.) “Sit in silence, go into darkness, queen city of the Babylonians; no more will you be called queen of kingdoms." What could cause an event like this? It sounds like an EMP (electro magnetic pulse) attack. An electro-magnetic discharge like this would instantly fry sensitive circuits and fulfil Isaiah 13:5. More importantly, it would take only takes one warhead to be detonated above America. Silence and darkness would follow HEMP This stands for High-Altitude Electro Magnetic Pulse. It would be detonated about twenty miles above the country.

Then, as described in the Scriptures, (Revelation 18:8.) "Therefore in one day her plagues will overtake her: death, mourning and famine. She will be consumed by fire, for mighty is the LORD God who judges her."

The invasion will follow swiftly. (Jeremiah 50:2,14,15.) “Declare among the nations. Lift up a signal [to spread the news]—publish and proclaim it, do not conceal it; say, Babylon has been taken, set yourselves in battle formation against Babylon on every side,
All you archers. Shoot at her! Do not spare the arrows, for she has sinned against the LORD. raise the battle cry against her on every side! She has given her hand [in agreement] and has surrendered; her pillars have fallen, her walls have been torn down. For this is the vengeance of the LORD: take vengeance on her; as she has done [to others], do to her." Also, (Jeremiah 51:3-4.) "Let not the archer string his bow, nor let him put on his armour. Do not spare her young men; completely destroy her army. They will fall down slain in Babylon, fatally wounded in her streets."

The Scriptures unfortunately, describe in great detail the end of America. The words of our LORD Jesus Christ are in the Scriptures I have put down here. Therefore, ask God His timing (if you live in America) when to leave. There are clues for His children to stay in His Will. To see the warning signs that it is time to leave and go to Jerusalem to be part of the group which will flee to Petra (a place of safety) to be taken care of by our LORD for 1,260 days. Amen.

Escalation in the troops on the ground has increased. ‘Soldiers from 20 countries will be gathering in Saudi Arabia for massive military exercises’, was in the news.

When will things start to become serious? President Putin as stated has already done a partial removal of troops from Syria but can move back within hours if needed. The phrase ‘She’s more clever than her sister’ comes to mind although brother would be a better word here! I’m sure most of you reading here know that America and Russia don’t exactly get on well together. So what does Bible prophecy have to say about these two countries or indeed biden and Putin? Quite a lot actually but it’s well hidden within the prophecies of Isaiah, Jeremiah & Daniel. The Apostle John has things to add too in the book of Revelation.

Here’s a few Scriptures to start us up.
(Jeremiah 51:53.) "Even if Babylon ascends to the heavens and fortifies her lofty stronghold, I will send destroyers against her,” declares the LORD." (Isaiah 14:14.)
