BIG TWIN® EVO® TAPPETS Stop tappet noise forever with big axle “Powerglide™” hydraulic tappets for Evo performance and stock Cams (Will also work with solid style cams) For pricing, visit www.motovan.com in the dealer section. 187 The title tells the whole story. Power is what you are after when you’ve installed a high performance hydraulic cam in your Evo motor. To get full power, you must have zero valve lash, and eliminate collapsing of the hydraulic tappet as found in stock hydraulic units (this is referred to as the shock absorber syndrome). Failing to open the full amount, as the cam is designed to do, results in power loss. “Powerglide™” eliminates the shock absorber action. “Powerglide™” is as close to a solid tappet as possible and is still able to compensate for heat expansion. Glide is what you get when hand matching hydraulic components to a running fit of 0.0002”. For this reason “Powerglide TM11 tappets have a microfinished bore for the hydraulic unit to glide over. ii Powerglicle TM11 tappets are right at home in H.D.’ tappet blocks unlike other performance tappets that require special tappet blocks. These tappets will run in cast iron or aluminum tappet blocks. JIMS’ recommends fitting the tappets to the blocks with a clearance of 0.0007” to 0.0012”. For worn out tappet blocks JIMS® is proud to offer +0.002” and +0.005” oversize tappets. The Powerglide™ advantage 1. Longest valve train engine life. 2. Produced from billet bearing steel. The same high quality steel our shafts and crank pins are made from. 3. The best JIMS’ made big axle roller. 4. The ultimate in hydraulic control system, performs better under both the lower and the higher R.P.M. limits, and high spring pressures. 5. A true centerline, for roller life and exact cam timing. 6. State of the art pushrod seat, machined with the same segmented parabolic cup as the JIMS’ roller rockers. Helps eliminate pushrod whip. 7. Engineered on a state of the art cad system, and machined in some of the worlds most accurate precision computer controlled machinery. 8. Hand fit hydraulic unit to a running fit of .0002”, with ultra precision air gauging system. 9. All hydraulic units are tested 100% for function under a simulated pressure test fixture. 10. The best warranty policy in the industry. “Powerglide™” tappets are capable of the highest rpm a Harley® can safely turn about 8025 r.p.m. at a valve lift of. 700 “, with the right valve springs, valves, Cam, oil, etc. We recommend using with JIMS® tappet blocks #53-0046.
