Hi Guys, Thanks in advance for any and all replies/help. I recently purchased my first Dozer, wiith alot of help/advise from many forums. Dozer is in fair to very good shape. I am the third owner, it has been well serviced. Final drives have no shavings nor water just dark oil in them. The seller let me run it on his property for 3 hours and it functions as it should, no issues. After first 2 hours I pushed dirt hard and the tracks never stopped or slipped.I removed floor pan to access the original battery cable that was replaced but left in place and causing a slight bind on power shift lever. a few zip ties and rerouting and lever moves freely. Now to my concern, while the pan was out I checked the u joints and they are fine but the collar/yoke to the trans is loose - has play about 1/4 inch of travel. Is this normal ? is it just a matter of removing u joints and tightening up a pinnion nut ? I dont plan to work the machine in buissines or contract work, we bought it to clean up our ranch, occasional use. Thanks to all who reply.
Not exactly relevant to your issue but the first recommendation for a machine from that era would be to get hold of a good set of manuals; Parts, Operation/Maintenance, & Service, especially if you propose to maintain/repair the tractor yourself. Here are the Cat Publication references so that you can search for them. O&M - SEBU5941 Parts - SEBP1133 (for machines up to S/N 6607) SEBP1294 (machines S/N 6608-Up) Service - SENR7432
Thank you Nige, found them and I have ordered them and by all descriptions they seem like the coorect manuals. I also found a pic of the u joint assy. and it looks like a splined yoke. I will be tighting it up!
