Overload clutch

Hi Paul,

Don't get the overload clutch (a.k.a. slipper clutch) and the gearbox friction torque check mixed up. Two different animals. The overload clutch (a.k.a. slipper clutch) on the engine side uses a tremendous amount of ft/lb torque. I personally don't do this unless it is a special needs check. This check can bend engine frames fairly easy without proper support.
The friction torque check in the gearbox is easy and won't hurt the engine frame. It is the measure of the 3 bellville washers spring pressure in the gearbox.
The video you are referring to here on the forum is for the gearbox friction torque check. Just do this check. The 230-530 in/lbs they are using are guidelines. What I normally see in the shop is
425-485 in/lbs for normal numbers. If it drops way down in the lower 300's I will pull the gearbox and re-shim.

Look in the Line Maint. manual. Section 05-50-00 page 5 describes the overload clutch check.

Section 12-20-00 page 68 is for the gearbox friction torque check.
