I haven't finished writing the web page for rebuilding the nosedrive. You can use the info at www.rollingperformance
as a general guide, even though it'* for an M90.
I need to stress that if you haven't done bearing work like this in the past, you shouldn't attempt it. If you're rebuilding your nosedrive, DO THE NEEDLE BEARINGS ALSO. You'll have it apart anyway.
To date, I think I'm the only member here that'* rebuilt nosedrives. I'm doing another in the next month or so, so if you can wait that long, I can get more specific for you as I go through mine. Press depths and techniques are the key.
A word to the wise for the M62'* like yours, because of high mileage and faster rotating speeds, do NOT go with the Viton seal. It'* not soft enough to mate with the groove probably worn into your input shaft. You'll have a leaky nosedrive for a couple months until it 'breaks in'.
