Download INSTALLATION INSTRUCTIONS FOR 6 SPEED CONVERSION KIT AND 6 SPEED BUILDER KIT We recommend the kits are installed by a qualified mechanic with knowledge of the Harley-Davidson 5 speed transmission. Also make sure you have a 1990 or later Factory Service Manual available. Tools needed are the same as used for a 5 Speed transmission. The conversion kit should only be used in new or low milage transmissions. If gears or bearings of a used 5 speed transmission are worn, new ones must be installed, or better, the builder kit should be used. Gear set RemovalRefer to the Factory Service Manual Section for Mainshaft and Countershaft removal. When you get tothe point of actually sliding the gear set out make sure you properly mark the 5th gear set as described inthe Factory Service Manual (for used transmissions only). Further follow the factory removal procedure. Clearance ChecksThe 6 Speed conversion and builder kit will fit in most OEM or aftermarket transmission housings without any modification of the housing. However due to casting differences, in some instances some modification may be needed. The following clearances must be checked before assembling the 6 speed transmission.
