1) Remove the pressure plate assembly from the clutch to gain acces to the mainshaft. Install the basket per

the OE service manual. If needed, re-install the clutch pack with the .120” thick steel plate installed first, then

a friction, then a steel until all the plates have been installed. Next install the billet aluminum pressure plate,

the diaphragm clutch spring, spring retainer, nut lock plates, and shouldered nuts. Tighten the nuts equally

until all are bottomed. The diaphragm clutch spring should be with .010”-to-.020” of being flat (slightly con-

2) Adjust the clutch per the following in-

structions:

a) Turn out the cable adjustment until

the clutch lever rests against the grip.

b) Install the center adjusting screw

and thread it in until the clutch lever

just starts to move away from the grip.

c) Turn the center screw out ¼ of a turn

and lock the center adjusting screw

jam nut firmly against the pressure

plate.

This kit includes a complete basket assembly with a splined hub and 37 tooth

sprocket made with ultra dense high strength 7075 aluminum and fits 1990-93 Big

Twin applications. The kit also includes an 84 tooth ring gear which requires a special

pinion gear (part #1170-0021). This pinion gear must be used with this 84 tooth ring

gear. DO NOT use the OE pinion gear as damage will occur.

3) Now adjust a black cable so you

have approx. 1/8" free play from the

clutch cable ferrule to the clutch lever

perch and on a braided cable you will

have almost no free play.

4) Install the adjuster screw with lock

nut (included in kit) into the pressure

plate.

5) Install the outer primary cover, fill the

primary with Dexron III ATF fluid so the

level is just slightly over the bottom of

the ring gear.
