70 Diesel Pony Motor Clutch Adjustment

Needing to tighten up the pony motor clutch on the old 70 Diesel. The service manual talks about adjusting the yoke that actually operates the clutch so the stop pin protrudes 1/16" with the lever at dead center, but doesn't seem to say a whole lot about whether there is any adjustment to the clutch fingers themselves. I'm assuming so, since there is an inspection cover on top of the gearcase. Are there any adjustments to make to the fingers, and how would I go about it? Do any of you guys have any tips for making adjustments on the linkages and such? Thanks to all of you guys in advance for all of your help.

Matt,

This is how I set the clutch fingers you speak of, excuse my carpenter tools, I actually have an old screw driver that is bent on the end to protrude about 5/8" that I can reach in through the removable cover. To cloud what you said about the stop pin adjustment I have three pony start diesels and the plate that the stop pin protrudes past is different on all three. Trying to get the clutch adjusted so the brake stops the pinion gear from spinning and grinding against the fly wheel can be finicky. Adjust according to the manual is a good starting point.
