Good morning, I followed Rob's videos and replaced the bearings and seals on my Sutorbilt 4ML. The videos only show the front side of the blower what do I need to know to replace seals and bearings on the back side where the gears are located?

Thanks in advance

You'll need Rob to make another video.

Are they bad? Generally they only go out on the drive side.

I doubt they are bad but it was leaking oil I assume it is the gasket but the kit I bought had rear bearings and seals as well and I figured since I was doing it I might as well do everything. If a rear seal was leaking oil assume I would have found oil inside on the lobes and shaft.

I have torn down many engines to the crankshaft and rebuilt them...but the only 2 Sutorbilt blowers I took apart to do the rear I was never able to get them back in time when I reassembled them.
I think it takes a experienced rebuilder when it comes to a total rebuild on them.
Just my experience though.

I appreciate your input. Your experience reinforced my decision not to fix that which is not broken.
