This is the ORIGINAL 6-speed design that revolutionized the American V-Twin industry. Yet, it’s still the best overdrive 6-speed built to this day…hands down. Our OD6 is built to comfortably handle the power from today's big-inch motors. This transmission is rated for motors putting out up to 165ft/lbs of continuous use. It is available as a complete transmission with a wide variety of case options and configurations, or as a builder’s kit for your stock case application, which requires little to no modification. The BAKER OD6 is available with many optional gear ratios to match your engine torque and riding style.
OD6 bearing doors are a 1/2″ wider at the mounting flange then a stock 5-Speed door due to the 6th gear. The OD6 door comes with or without an ear. The ear door is for exhaust bracket mounting and does not fit 1993-2006 FL applications. Note the images below. The OD6 door bearings are larger providing 25% more dynamic load capacity than stock bearings used through 1998, also uses a 1/8″ bearing retainer plate instead of stock style snap rings.
Our 6 Speed shift system with roller detent guarantees smooth shifts every time and our redundant neutral ensures that finding neutral is a easy chore. We mount a plunger detent on the left side pillow block and cut a plunger track into the shift drum itself. The plunger follows this track during operation (shifting) and when shifting into neutral pops into a pocket. This system lets you feel that you’re shifting into neutral. No more guessing. Shift drum features more aggressive timing on the fork groove profiles and is case hardened to 58 Rockwell for wear resistance and crisp shifts. We built our reputation on smooth shifting 6-speed transmissions; our drum designs benefit from the engineering lessons learned.
FL Case Differentiations
To see an illustrated example of the differences between FL cases by year, please open the PDF here.
All OD6 gearsets are made out of 8620 steel, gears are cut before heat treat then precision ground with diamond coated tooling after heat treat (58-62 Rockwell ‘C’). This extra steps ensures not only a quieter gear pair, but enables much tighter backlash control. This tighter control on the gears yield a silent operation.
The OD6 comes in a standard ‘2.94’, optional ‘3.24’ or R-Ratio ‘2.82’ configuration. A way to physically tell which ratio you have is pretty common knowledge here at BAKER, but if you would like to know look at the 1st gear pair on the gearset. Our standard 2.94 1st gear will not have a notch on the 1st countershaft gear, our (stock) 3.24 1st gear will have a single notch around the center of the 1st countershaft gear and our 2.82 (R-Ratio) 1st gear will have 2 notches around the 1st gear countershaft. Use the image on the far right for reference. This is very important to know if you need any replacement parts or components.

Our investment cast shift forks are made out of 4140 then dipped in a hard chrome plate bath for wear resistance, also designed with oil reliefs to ensure proper lubrication and wear resistance on fork blades and shift dogs.

Builder’s Kit Notes
-We started providing install DVD’s with every builder’s kit starting in October 2012. At approximately 3:25 of the OD6 portion of the DVD, Bert talks about modifying the shifter pawl. This modification is related to the stock shifter pawl lever assembly (H-D PN 34972-02B) and the use of BAKER 5-6QSN & 5-6QLN shift drums. We now provide a shift drum BAKER PN 124-0D6, which supercedes the 5-6QSN, 5-6QLN Shift, 5-6QEN, 5-6QFN & 5-6QGN shift drums, that requires no shimming and works with BAKER shifter pawl 555-56C or 555-56L (depending on year or motorcycle) which we include in kits and on all BAKER complete builder’s kits. We do not sell any kits, shift drums or transmissions that require any shifter pawl with BAKER marked on it, that needs to be ground or modified anyway. Any questions, please call us at 877-640-2004.

Recommended Fluid / Level
Picking the right transmission fluid ensures the life and durability of your transmission, that’s why BAKER recommends a fully synthetic GL-5 rated gear weight oil of 75W-140. If a GL-5 rated gear lube is not available, these commonly carried viscosities (weights) will work 75W-90, 75W-140 and 85W-140. BAKER does not recommend the use of Syn3 (20W-50).
