If
your 9N/2N is leaking fluid from your PTO bearing housing, there's a
good chance your PTO bearing seal needs replacing. If your transmission/hydraulic/differential
fluid isn't in need of replacing, follow these step for replacing the
PTO seal. This PTO assembly was used on the 9N/2N tractors from 1939
to 1943.
- If you're not planning to drain the transmission/hydraulic/differential
fluid, park the nose of your tractor in a ditch or back the rear tires
up on some ramps. You won't lose any fluid this way when removing the
PTO shaft assembly.
- Remove the 4 cap screws holding the bearing retainer to the center
housing. Remove the PTO shaft assembly from the tractor.
- Remove the cotter key and pull the pin out. This will allow all
the guts to slide off of the shaft.
- Inside you'll find a seal that looks like this:
A local New Holland dealer will have or order the seal you need for about $18. At this point you can determine if you need a new bearing. If not reassemble in reverse order and your done. Put a new paper gasket on when reinstalling the PTO bearing retainer to the center axle housing.
