HELP!!!!GRAVELY COMMERCIAL SERIES PTO

[jdboy4410]

just looking in an old manual i have for the L models and it states as follows:
the clutch is properly adjusted when there is a .025" gap between the coils of the clutch springs,if excessive slippage occurs,decrease the gap to .020".
that is how it is written in the manual,i tried it with no success.the torque wrench method i think would be preferred to check the force needed before it slips.my buddy found out the hard way with his snow thrower,the clutch was too tight and it broke the output shaft on the snow thrower rendering it useless now.i think i am going to invest in the torque wrench set up myself so i can get it right without worry.i would sure love to lay my hands on a true factory service manual for these machines ,,,,,,,,,,,

All of the manuals are at oldgravelys.net

Look at the old model L manuals. They show how to adjust the PTO clutch using a spring scale and a piece of bar stock.

i will look at that manual for sure.i neglected to mention that you would have to use a turning type torque wrench.i seen where someone offers a socket to use with that method.those torque wrenches are expensive to buy if you do not have one.a standard torque wrench will not work as it is designed to tighten a fastener to a fixed point,a turning torque wrench reads the force necessary to turn like checking a differential for bearing preload,or,the force necessary to slip the clutch in this case.
