I thought I recently had a hydraulic pump failure.
Turns out, the hydraulic pump is driven from a gear on the end of the fuel camshaft.
The bearing for the fuel camshaft failed, and the camshaft was pushed downward by the injector assembly, thereby disengaging the hydraulic pump gear.
So, the hydraulic failure was just a symptom of the main problem.
So... I need to replace the fuel camshaft bearing.
This is the fuel camshaft.
Bearing #130 is the one that failed and needs replacing.

Here's the hydraulic pump diagram.
#20 is the cast/machined part that is damaged and needs to be replaced.
The #60 gear is attached to the splines in the above fuel camshaft diagram.

Failed bearing... no balls... just inner and outer race.
Housing damage.
Questions...
1. Does the bearing come out, in the direction towards the splines (towards the back of the tractor)? Or does the entire fuel camshaft need to be removed (from the front of the tractor), and bearing is removed by pressing it inwards, towards the cam area?
2. Any recommendations on pulling the bearing from the shaft and the race from the case?
3. Since all the bearing debris and balls are in the crankcase... I suppose I need to remove the oil pan to clean it out? Any recommendations on removing oil pan (4WD shaft is in the way). Drop the front axle trunnion... and/or remove driveshaft??
4. Any other recommendations on other repairs in the fuel camshaft area, while I have everything torn apart?
Thanks for any help.
