This Komatsu PC 2MR-2 excavator is in the process of being taken apart. In this video, we show you how we removed the counterweight and upper structure on the excavator.

The Komatsu PC 2MR-2 is a mini excavator that weighs around 16,000 lbs. We have to crane the counterweight off first because it is too heavy to lift off without a crane.

It’s important to disconnect any batteries when working on equipment. This way, there are no electrical hazards.

We then use a forklift with a basket attached to pick up the upper structure. This will allow us to move it closer to the truck for loading. After this, we remove the boom and cab from the upper structure and load them onto our truck for transport back to our shop in Nashville, TN.

Rack and pinion systems are the most common kind of power transmission in excavators. They use a set of gears to transmit power from the hydraulic pump to the excavator’s bucket or ripper. Rack and pinion systems are commonly found in other machines as well, but their placement is not always obvious. So if you’re looking for them, look at the front of your machine.

Most excavator racks can be accessed from underneath the machine. The main parts include the main shaft and drive sprockets on either side, the main parts sprocket on top, and two smaller sprockets that hold a pinion gear.

For safety’s sake, remove any guards first before inspecting your excavation equipment parts. Also check to see that all bolts and nuts are secure. Once everything is secure, find the back end of the drive shaft — you can usually tell it’s there because it will have a cover over it — and carefully lift it up until you can access the pinion gear behind it with a socket wrench or socket extension.

komatsu pc 2mr-2 excavator-torque to factory specs. if you are not sure what they are, check your manuals.

The best way to know what the torque specs are on your komatsu pc 2mr-2 excavator is to check the factory service manual. You will find it in there, or can call your local komatsu dealer and ask them for a copy.

The first thing you should do is make sure all the bolts are clean and free of debris. After that, crank down until you feel resistance and then about 1/4 turn more. This is not a very good method and should only be used when you have no other options.

The second method is to find a torque wrench and set it to the correct setting for your application. Then just crank it down until it clicks twice.

The third method is to use a torque wrench and an impact gun. These two items work well together because they allow you to get the right amount of torque without over tightening.

You can also use an impact gun by itself but this can lead to some problems if you don’t know what settings are needed or how much force should be applied without damaging anything else on your engine block.

The last option would be using a hydraulic press but these types of machines are expensive so unless you’re willing to spend money then this isn’t really an option for most people at home

The first step is to get your hands on the right part. You can find out what that is by consulting the owner’s manual or by calling your local dealer. Before you take the machine in for repair, make sure you have a good idea of what caused the problem in the first place.

If you don’t know exactly what’s wrong with your machine, but it seems to be rusty, worn or has other signs of wear and tear, then this might be a good time for you to consider having it repaired. If you have experience doing so, then there’s really no reason why you shouldn’t be able to handle this yourself.

The next step is to remove the old pinion from your machine. This will likely require some elbow grease and a little bit of patience, but if you’re careful it shouldn’t take more than an hour or so. After removing it, take note of how many bolts are holding it in place.
