Looks like your dad might have been a Studebaker man! My grandfather would use nothing else on his farm in the 40's and 50's, even though he had to drive 40 miles past the Chevy and Ford dealers to get them worked on.

That was a 1 ton Studebaker with an Olds V-8 engine! Lots of power to pull around heavy equipment. Empty, I used to blow off Fords and Chevys who would pull up at a stop sign and challenge the frumpy looking Studebaker!

Thanks Eddie
That is what I was looking for. The picture came out good but the printing is too blurred to read. I figured out most of the first paragraph, but not the second. Is there some way to scan the page so the text comes out clearer? Thanks from California.

I have found sometimes if you copy the text on the copier that you can read it more clear on the copy.

"This adjustment is unnecessary on tractors below L-919 and PL-708. Tighten the gland only enough to prevent loss of large quantities of oil. A slight seepage around the sprocket hub is beneficial, rather than harmful, as it keeps the packing lubricated and the dirt from working in."

"Adjustment is made through nuts on three studs protruding through final drive gear case around the sprocket hub. Remove sprocket guard, and final drive pinion outer bearing cover. Remove three cap screws holding sprocket hub dust guard to final drive case and lift out guard. Loosen lock nuts, take up on adjusting nuts, each the same amount, and tighten lock nuts. Replace guards."

Hope this helps. Some times younger eyes make all the difference.

Thanks again. I was able to print out your re-scan and could read it just fine. Also, EQUIPDRIVER typed the instructions out in his message. Thanks to him too.

The big Twentys, S and PS Thirtys, and the Sixtys all used the same type of final drive seals. The outer end of the sprocket hud is sealed with a spring loaded cork, and as far as I know is non adjustable. The inner seal is a packing like a water pump packing except with a much heavier cross section, this seal is adjustable. If I can remember when I get home tonight I will get the adjustment instructions for both the sprocket hub bearings and the seal and post them in Thursday morning. I should have ask what the serial number was because there were two or three different types of final drive seals used on the big Twentys. The bellow seals were added at the start of the Twenty Fives.
Thanks
