Which is the best way to adjust hydraulic valve lifters?
If you can do some mechanic work by yourself then adjusting the hydraulic valve lifters first will be your best go. Else, you can go for changing the oil. Generally, lifters are self-adjusting. But sometimes the lifters may go to the wrong position that may lead to noise.
Do you need to replace the camshaft when replacing lifters?
Mostly old school..! The camshaft does not necessarily need to be replaced when replacing lifters, and often times is not. In the case of a 4 cylinder, especially, I would replace lifters without doing the camshaft since you can replace the lifters without removing the head.
What kind of lifter does a 2012 flstc have?
My ride is a 2012 FLSTC and I’ve already installed the SE Stage 1 air kit, Rush slip-ons with a 1.75″ baffle, and a Doebeck EFI. I’m installing new cams (S&S 583), inner cam bearings, S&S Quickee Adjustable push rods, and at the last minute decided to install new lifters while I was in there.
How are s and s lifters installed on a Harley Davidson?
However, on a stock Twin Cam motor, Harley always assembles lifters with all oil ports facing outward. We usually copy this assembly, just for what we consider to be good mechanical practice. Hold the S&S lifters into position with the alignment pin, then install the tappet covers with new gaskets.
Are there lifters on a Delphi twin cam?
1 person likes this. So if, essentially the Johnson lifters were specially made for the twin cam , and the Delphis do not have the volume needed to quiet the clatter, would or does that make the valve trains on earlier twin cams quieter than the ones with “B ” lifters? I have not seen any info that would confirm or deny this, just curious.

What happens when you turn the camshaft wheel?
Turn the camshaft wheel until you see the V-shaped timing mark at the top. If these timing marks are not aligned properly during assembly, the camshaft will be out of phase with the crankshaft and the valves may be damaged if they strike the pistons.
Why are roller camshafts used in racing cams?
The bearing rides on the camshaft lobe eliminating much of the friction and allows for smoother lifter to lobe contact. Roller camshafts are available in a wide variety of profiles. These profiles have faster ramp rates or lobe acceleration for quicker valve opening and closing.
What should I do if I cannot find the timing marks on my camshaft?
If you cannot find the timing marks, DO NOT remove the camshaft – consult a motor manual. After removing the timing chain and lifters, place the cam sprocket back on the camshaft and revolve the cam in the block by hand and observe how freely it turns. Your racing cam should also turn this freely in the block, when installed correctly.
