HELP. CAT 225 excavator. New to us machine, multiple issues

You may want to try google "heavy equipment forums" and post this in the excavator section if you havent already done so.

............................up in the frozen north guys weld guides in between top rollers and idlers on long track machines to help keep the track in place.

rollers can be welded and turned if your rich. They made alot of 225s you need to find a tame breaker that deals in the older Cats.

lf i may be so bold as to suggest you sit down and list all the issuses and cost from a tame breaker that need to be addressed and make a plan. The reason i say this that old heavy equipment major repairs gets very expensive very quicking, its like painting the Forth bridge running old heavy equipment your never done, you may be better of finding another for spares or use this one for parts.

Good luck

I did try to join those forums but when trying to post, it says restricted. When i contact the admin, I get zero response so I guess whoever runs it does not really care. Sucks because that seems the appropriate place to get some questions answered..

See if you can find the "fine print" for the Heavy Equip site. Something about having to sign in and review a number of posts before you can post your own. Effort to keep down the number of spammers, or something like that.

thanks for that! I will see what I can find.

Fastline,

I have been a registered member for a while and have found that there are some very helpful people there. they do have a specific section for Excavators... i watch the Track Loader one myself.

good luck.

rod

Regarding the tracks, if you plan on running 'em to ultimate destruction you could always release pressure in the tensioner cylinders and take one link out. Time vs money; rebuild the rollers (if the bearings aren't totally shot). .gonna be cheaper than getting new ones and the only investment will be a few pounds or wire or welding rod + your time.

As far as the boom, it's been a few years since I've been around excavators but I'm wondering if the solenoid/ pilot valve isn't worn and chattering a bit. You might get a partner to take a stethoscope and have 'im listen to the valve while you're running it.

First thing to check on the boom is it fitted with safety check valves and if so you will need to have someone with experience and gauges to check the the pressures and operation,the pumps drive gearbox has oil and it is important to make sure the breather is kept clean and the oil is kept at the correct level and not overfilled,taking a link out is the norm with that type machine to get the last bit out of the tracks,run them to destruction and then get a set of chains,rims and rollers,those are a good powerful digger and if it holds up to run the tracks out it will be worth having good undercarraige on it and it will last for years.

Listen to the pumpdrive as someone cranks the engine and shut's it down. If you hear a lot of clanking, it's wear between the aluminium drive ring on the flywheel and the spider on the pump drive. The spider has MANY rubber tips on it. Best case would be worn ring and tips. If your machine has a peddal on the floor back by the seat(not the two travel peddals) it is to allow two pump flow for boom up and stick out. If two pump flow is on and the Crossover spool is set too low it may come in before the main bom spool has moved dead ending the flow of one pump. That will make for noise and a jerky boom up.

You might also check the filters, Most hydraulic system are very sensitive to dirty filters.
