Thanks for the video Doc! I am going to order a dial indicator and you helped me understand the inner workings of my own bike better for when its time to upgrade my cams. The heat expansion and mixed metals is a wonderful tip and mixes in history as well, that knowledge helps when talking to people who know their stuff. Great video Doc.

The aluminum case expands more per degree than the steel camshaft, so endplay *increases* as the engine heats up. I shoot for .005-.008" on the camshaft endplay, and check it with a depth micrometer at the end.
@video-dispatch830910 ай бұрын
Out of curiosity, how did you verify that the case would expand that much? Wouldn’t it be safer to shoot for the absolute minimum of the factory range, especially since Harley offers a fairly wide range of acceptable play to begin with?

@@video-dispatch8309 the coefficient of thermal expansion is established matter of physics. How much it expands is irrelevant, but aluminum expands more per degree of temperature increase than steel, that is a fact.
@josephtese503710 ай бұрын
@@patrickzambori473 Wouldn't it matter very much how much it expands? Because until the engine is warmed up enough to reach the minimum allowable end play, you are running it too tight until then. That's all I'm wondering about. By the way, I'm here to learn and ask questions; there is zero motive in me to sound critical or challenging.

The steel cam cannot expand as much as the aluminum case does, so the endplay of the cam is only going to increase as the engine heats up. @@josephtese5037

Requesting a new topic. I have some high speed wobble on my 1988 FLHTC Electra Glide Classic with 32,000 miles. Can you address replacing motor mounts / isolators? I assume they need routine replacement on newer Harleys too. Any comments about the after market motor mounts / isolators that are supposed to cure "Harley Death Wobble?"

DOES THIS MEAN ANYONE CAN SWITCH TO GEAR DRIVE ? I WAS TOLD IT ALWAYS DEPENDS ON THE CAMSHAFT OR is it CRANKCASE RUNOUT. SO YOUR SAYING RUNOUT CAN BE CORRECTED, SO ALL MOTORS CAN SWITCH IF THEY WISH TO GO TO GEAR DRIVE CAMS ? I WENT S+S GEAR DRIVE MANY YEARS AGO, TO ELIMINATE this TENSIONER ISSUE

@Alan Whiteside what's the cost difference when you might use 1 time in the life of one motor. Someone who regularly is installing cams verses someone that might do this repair once or twice. I've turning bolts on autos, bikes, and boats for 55 years. I have plenty of tools. If your good you don't need every gizmo that comes out. My garage is only so big.

@@3percentmick705 actually I have been watching videos about cams for a few days because I am having a upgraded cam and cam plate put in my 04 flstfi and pipes, this winter. I find that all his videos I learn more and more about how my motor works. So when I have to bring one of them to the shop because it's not running right, it's nice to be to talk with my mechanic and have some understanding of what goes into fixing my bike and why it takes X amount of hours to fix. Anyways I appreciate all his videos
