Run the biggest cam you can find for a shovel to help squeeze out all the horsepower you have put in your shovel; with the right valves, valve springs, pistons and oil. No longer will the oil you have been trying to get to your rockers, through outside oil lines, be lost at the clearance around the rocker shaft to the rocker cover. With all four rocker shafts (new or used) having this clearance the amount of oil going to the rockers will be greatly reduced. With these components; POWERGLIDE tappets, roller rocker arms, billet tappet blocks, adjustable pushrods, gaskets and plugs, you will have a valve train system that works without any maintenance. No longer will valve adjustments be needed every 2,000 miles as before with other hydraulic or solid tappets. POWERGLIDE TAPPETS: These use the same hydraulic unit as JIMS ® EVO and Twin-Cam tappets, they can be run against valve springs having over 800 lbs. of spring pressure (valve open) with cams having as much as .700” valve lift, axle roller installed within .0002” of parallelism to the body. The body is ground to better then a 16 finish and straight and round with in .0002”. Also uses a low pushrod cup, having an optimized metering oil channel. ROLLER ROCKER ARMS: The a ratio of 1.5:1 gives the valves far less roller tip push then any other shovel rocker being manufactured. Combining the above with 660 bronze bushings, line honed to .0007” fits to the rocker shaft. Roller tip and it’s axle made from tool steel with pressurized oil hole, that will help lubricate not only the roller tip but also removes 35% more heat from the valve springs. Also a pushrod seat design (segmented parabolic) that will increase pushrod life by 35%, which now is lubricated with pressurized oil from the pushrods 3/8” ball end. TAPPET BLOCKS: Blocks have been machined to the precision tolerances JIMS ® is notorious for. All bores have been machined straight to the centerline of the cam thus increasing tappet and cam life. We’ve also designed the most advanced oil drains to help remove all the oil being returned from the heads to the return side of the oil pump. Included with all this precision machining we’ve added the best chroming process in the industry. PUSHRODS: Adjustable pushrods with 24 threads per inch for ease of adjustment including stainless steel locking nuts to help hold adjusting screw tight. Light and straight with an oil hole threw both the pushrod ball ends similar to EVO and Twin Cams. With the above JIMS ® powerglide tappets, JIMS ® roller rockers and these pushrods, you will be able to remove your top end oil lines and plug them off with supplied plugs. Now with all this installed to your valve train, your new top end oiling system will be updated to JIMS ® top end oiling system, being the same as EVO and Twin Cams. How it all works, oil that is pumped through the powerglide tappets, through each pushrod, thru each rocker. For more details see No.1046-IS instructions.
