I was laying in bed trying to forget it was Monday when the phone wouldn’t stop ringing, no matter how I tried to ignore it. It was Paul Platt, from JIMS, who immediately launched into complete description of JIMS new 6-Speed replacement gear set without taking a breath. After shaking out the weekends cobwebs I figured I’d better get my dead butt over to JIMS Camarillo headquarters and find out what was what.
 Upon arriving I found JIMS head wrench, Tom, hard at work installing the 6-Speed into a stock H-D, so we decided to chronicle the event for you to check out. This install can be done by any shop, or by a wrench with tranny experience, and JIMS tools.

JIMS 6-Speed (Photo 1), and every piece in it, is manufactured right there in JIMS shop. Home grown and quality controlled right from the start. Total CNC (Computer Numerical Control) production makes for the closest tolerances in the industry.

The gear teeth are spun on a Koepfer Gear Hub with a 7 axis CNC control. The gears are then put through a vigorous quality control process on another Koepfer machine. This one checks the profile, lead, pitch measuring and run out. JIMS also demands the highest quality steel available in the world today, insuring the finest gearsets available.

We figured that anyone who felt qualified to do this procedure would already know to handle the primary case, so we’ll start our work with the primary disassembled (Photo 2).

First remove the old gear set. This starts with the removal of the side door cover, containing the clutch release mechanism. Then the side door assembly, with the gear set attached, is pulled (Photo 3), using JIMS  5-Speed Door Puller Tool # 2283 (Photo 4).
