Track Experience Needed

My understanding is very shortly after Cat came out with the 955 based on D4 and 977 based on D6 tractors they found the loaders were harder on tracks so put D6 track on the 955 and D7 on the 977. If this is the way it is, I would guess there is no easy way to do what you are hoping to do. So somebody prove me wrong so Ricky can get this loader loading again.

The 977 and D7 bed roller will't fitt on D6C TRACK FRAME

The 977 and D7 bed roller will't fitt on D6C TRACK FRAME

Caterpillar 955L Loader Track Rollers Part No. Machine Serial No. 85J6782, so will these fit the D6C 74A ???

 

Gemdozer is a Canadian that's first language is French. But he is easier to understand than some that only use English.😉 And I was not thinking of that down under English originally. But with further thought it can confuse me too sometimes. Some that levee words or parts of words out and no punctuation marks I generally don't try to just skip .

I cannot say as I don't know the time line of the loaders to the dozers. As well as Cat slipping the D 5 into the mix in the 60's and starting a new in-between size of track. The pre 1960 D6 track is 6.5 inch pitch, and then D5 is 6.91 inch pitch and D6C is bigger I think 7 or 7.5 inches. Somebody must know without having to look at the parts books

The d6c track pitch is 8 inchs and 955 and old 977 pitch is 6..750 inchs and bottom roller 955 and 977d inside bolt in frame is 12.500 and d6c is 13 inchs.
