Engine and Clutch Sprocket Locking Tools

4 Speed

Here's a very simple and easy (and free) tool to make to lock your clutch hub to remove or torque the nut.
Take 2 clutch discs and 3 steels, install them into your clutch hub assembly, drill two 5/16 holes thru the old
clutches and steels, and use 2 1/4 inch bolts to bolt them together. Leave the bolts just a shade loose so
fitting the tool back into the hub is made easier because the parts can float around a little. Now install your
2 pieces of 1 x 1 angle iron cut to 4 inches in between the sprocket and drum as a jamming tool and you are
all locked up without buying an expensive holding tool. 1)

This is the sprag I used to jam the clutch and engine sprockets to tighten the engine mainshaft nut (120 foot pounds). It has a divot cut out of it for the where the
footpeg mount goes in a 77 model. It is right on 4“ long and made from about 1/4” flat strap. It is wide enough to fit on all three rows of the teeth on the sprocket.
It is made from a piece of scrap metal so the countersunk hole is not necessary, just part of whatever it was before it became a special tool. It fits between the two
sprockets to stop them from turning 3)

A heavy duty 4“ door hinge works well.
A cheap 4” door hinge bends like a pretzel.
The derilin block just gets shredded up.
But, the heavy duty 4“ hinge works great. 6)
