I got an old 1973 sw48. Great for skidding logs. Had to change the sprockets just after I got it, they would actually skip! But they don’t come off from the outside, in their infinite wisdom, Bombardier makes it so the shafts have to come out of the diff unit. Looking at yours brought back some not so fond memories of removing the tracks and shafts to get at the sprockets. On the older ones like mine, you have to take the cab off as well if you want to get at the diff. That actually makes it a bit easier to get at the diff though. I was lucky, the bands were in pretty good shape, so the diff stayed in. I used a Cat brand oil made for this type of steering unit and it made it steer much better. I think they just had gear oil in them when I got it. You are correct, the service manuals for these are somewhat lacking! Good luck with the Bombi!
The entire final drive sits in hydraulic fluid, normally topped up through the dipstick hole under the plug below the right front of the windshield. It should be drained as part of the procedure for changing the bands.

OMG take the cab off? Really? Some engineers create planned obsolescence. Bombardier creates planned suffering.
Reminds me of the English joke about a hearse where the only way to change the oil filter involved removing the deceased's left shoe.
Grab hook on each side of the drums and you can lift the diff out
Thank you!
Is that sitting in a wet brake some kind of lubricant or is it dry

Is the brake band sitting in oil or do’s it work dry
@@matthewcollins6755 I am talking about the actual brake. steering bands or brakes wet or dry?
@@stanleybeaulieu528 Wet. They are part of the final drive, so they sit in the hydraulic fluid
Yes thank you sir for the information on the bombardier I appreciate it you have a powerful day
