BAKER Drivetrain has had their hands full since the last V-Twin Dealer Show. BAKER is debuting several new projects this year starting with the TTP otherwise known as the “Tin Type Primary” available in starter or kick only applications. BAKER took the classic 1936-64 tin primary design and re-constructed it with aircraft grade 6061-T6 aluminum to facilitate 1970-E84 Big Twin alternator motor case compatibility. BAKER addressed leaks, reduction in chain noise, and make modern starter integration possible. The Modern internal design of the primary utilizes stock style double row primary chains (428 chains) along fine tooth and L-bracket chain tensioner. The chain oiler feed and return provisions mimic the original primary setup so you can run your stock Shovelhead dry clutch components or leave it plugged off to run a wet clutch setup. Starter version is setup for factory 1.4kw 1990-2006 starters. Compatible with traditional tin derby and inspection covers or BAKER TTP Covers (sold separately). The TTP utilizes the 1955-64 non-compensator style motor sprockets in order to keep that tight/sleek appearance. Primary drive configurations are -24 tooth motor sprocket, 37 tooth clutch sprocket, and stock 82 pitch primary chain, for a 1.54 primary reduction. 24 tooth motor sprocket is maximum size that fits within the TTP envelope. -22 tooth motor sprocket, 35 tooth clutch sprocket, and 80 pitch primary chain (available through BAKER) for a 1.59 primary reduction. -23 tooth motor sprocket, 38 tooth clutch sprocket, and stock 82 pitch primary chain for a 1.65 reduction. Available bead blasted raw or fully show polished.

The BAKER Shovelhead Splined Clutch 1970-E84 is based off of their 9-plate clutch used on 1990-up applications and fits in the stock primary housing and TTP. BAKER offers 8620 gear steel 35, 36, 37, and 38 tooth clutch sprockets with their clutches, to dial in your overall gear ratio. The new splined clutch comes with or without 66T starter ring gear. BAKER?s one piece 66T starter ring gear and kick only clutch basket design is made out of 1145 steel, induction hardened T0 45-55 Rockwell C scale for years of wear free use. 9 two-sided kevlar clutch plates, deliver ample holding power for up to 125 ft-lbs of continuous use. Featuring a 6061-T651 aircraft grade billet aluminum pressure plate that is hard anodized for durability and specially designed diaphragm spring with ergonomic break-over feel during engagement yet having strong holding power when you put the throttle down.

Now if your thinking my shovelhead has a tapered shaft, BAKER offers the splined Shovel clutch kit. You know the sad story. The torque on the clutch nut backs off a hair and the key on the transmission mainshaft shears off. This usually happens at the most inconvenient time and place. And the probability of this sad story playing out is greater with performance applications. The kit Retrofits and upgrades the stock tapered mainshaft and clutch to a modern 18 tooth spline configuration. Kit includes a fully assembled clutch and splined 4-speed mainshaft to retrofit stock 1970-E84 Big Twins has an 18 tooth mainshaft to install into your stock 4 Speed.

The Jockey Top Cover is a new product to complete the puzzle BAKER started last year with the release of their 4 Speed for 1936-E84 models. The BAKER Jockey Top like the Ratchet Top comes with a snot-slick linear ball bearing detent for that smooth positive “snick-pop? shift quality you would expect. Made out of aircraft grade 6061-T6 billet aluminum with hidden vent and sealed shift shaft make this cover leak free. Available in FL / FX shift patterns, blasted raw, wrinkle black or show polished finish.

And last on the list is BAKER’s new Stash Tube made out of aircraft grade 6061-T6 billet aluminum with a screw on top and a .200″ thick O-Ring make for a water-tight seal. Internal diameter is 2.5″ by 4″ deep giving you plenty of room to conceal your items. Stash tubes come in raw or cat black finish with highlighted fins and fit all Knuckle, Pan and Shovelhead generator right side / alternator left side style motors.
