For instructions on Fuel Moto pushrods click here Wait for lifter to bleed down and repeat for each pushrod. Adjust pushrod per manufacturer’s specs and tighten jam nut (generally 2.5-4 turns depending on thread pitch). Rotate motor so pushrod is on the base circle and adjust pushrod to zero lash.
Install push rods adjust to the shortest length rocker arm end first. Align timing marks and torque retaining bolts in the correct sequence as listed in manual. To do so leave the oil pump retaining bolts about a quarter turn loose, put the transmission into 5th gear and rotate the engine to align/center the pump.
The HCR style tooth cut, introduced at the pinion connection in 2000 and on the rest of the connections from 2001 and on, does not require this precise fitting. Note: if you have not removed or serviced the oil pump from the cam plate you can simply re-install the camplate, however if you have removed or replaced the oil pump it will need to be aligned. Harley would precisely measure every engine crankcase and cam cover combination and choose cams that were a perfect fit for that motor, all in the name of noise reduction. Replace inner cam bearings and install the cam plate into the engine. Make sure to align the timing marks on the cams With the cam support plate now removed from the engine you can now remove the inner cam chain tensioner assembly and swap the old cams with your replacements. Remove the cam chain tension shoe, crankshaft sprocket bolt and rear cam sprocket retaining bolt, You can now unbolt the cam support and remove from motor. We use clips to hold the lifters in place which will prevent them from dropping in the motor once the cam plate is removed If using “Quick Install” style pushrods, carefully remove stock pushrods with bolt cutters Remove cam cover, put the bike on stand, remove the spark plugs, put the bike in 5th gear and rotate the rear wheel until the timing marks on the sprockets line up Type of riding: Do you spend a lot of your time. Primary application: Is the bike going to be used for all around street riding or is the goal to have an engine which is running at the maximum torque and horse power for track or drag racing 2. You will start by removing the exhaust system and RH floorboard. The three questions to answer before choosing a new cam for your Harley Davidson® motorcycle are: 1. Also the cam bushings on the case side are open to the crank behind them, and probably get splash there too.
Please refer to your service manual for specific instructions for each model The cam bushings get their oil from the fling off of the cam gears and drain back from the top end down the pushrod tubes that puddles in at depressions in the castings where the cam bushing slots are aligned. Here is some basic information and pictures from a cam swap on a 2010 Harley Davidson Ultra Limited. Performing a cam swap on a 2007-later Twin Cam motor is very straight forward.
