Cat D7 3T17311 Attachments

Trying to get information on the blade fitted to my dozer for parts. I have the Cat form 8628 parts catalogue but it has no info on attachments. Old Magnet give me some info on the sheave blocks when I was chasing parts for them from a 7A & 7S book. Is this the same parts book for the blade? The push beam balls attached to the dozer were flogged out which I have welded up back to a size (Don't know original size) but have one fixed bearing cup on the push beams flogged out which I want to replace. The cup which unbolts has 6F2905 stamped on it. I searched the net and found a part number 4J3590 for the part in mention but went to Cat today and was quoted 6F2904 as the correct part. Are these the same part.

Welding up that kind of joint seldom lasts long in actual productive use. Much better to spend your time welding new parts on.

Not sure if this applies in your case but sometimes the casting number is one digit different from the part number, so the part # Cat quoted might be the one you need. Old Magnet might know if there's a rhyme or reason behind that

Info is in the same 7A & 7S parts catalog.
Bearing is a 6F2904
Cap is a 6F2905
Trunion (ball) is a 3F4714

Casting numbers vs part numbers are usually off by the number of machining operations.
