Pinion oil seal

["Gordie's Garage" <mg_garage@comcast.net>]

Replacement in the tube type rear axle.
I'm reading the manual about measuring the torque required to rotate the
pinion (with special tool 18G 207) and using extreme care upon tightening
the nut because if you put too much torque (like > 4 - 6 lb. IN.) you'll
crush the collapsible spacer and have to dismantle the axle to install a new
one!
I need that pinion seal, but this ones got me worried.
Any tips?
