Cat Excavator Master pin

A Friend has a 1988 Cat Excavator 225 BLC needs to separate track to work on tensioner piston packings. Is the pin one piece or plugs in each end?? Has a divot (3/8Hole) in center on each end . Bob

Does it have a rubber plug in the center of the divot? That would be SALT track and should have an "alligator" link to separate the track..

Thanks - Not alligator link - will check again tomorrow and post picture.

If just standard sealed track, look for a pin that is solid flat on the end.

It is best not to rmove the track pin because the shock loades on ex. tracks from lifting loades that transfer enough weight to one corner sometimes can lift the rear of the machine off the ground. Driving the pin out can result in ending up with a loose pin that wants to walk back out. If you release the track tension cyl., backthe idler using the back of the bucket all the way back. Using the bucket by lifting the machine slightly and using the swing you should be able to push the track off the idler which can be slid forward and removed if necessary. Repeting the process usually requires using two chains to start the track over the idler. I have done thes on 225 and 235 excavators as well as a 500 Hitichi. Hopes this helps.
