Description
Harley-Davidson cam chain tensioner shoe replacement is a common project on Twin Cams from 1999 through 2006 (except for the 2006 Dyna). The Harley Twin Cam is a great engine but the cam chain tensioner shoes on the early models can be an issue. They may require replacement. Inspection can be as easy as removing the Harley cam cover and taking a looking at the front cam tensioner to look for wear. You have several options and we will show stock replacement and Harley hydraulic cam chain tensioner upgrade.

Polishing Harley Cam Chain
We've had this 2005 Dyna in the shop, a few different times now. Once, we demonstrated just Cam Tensioner Shoe inspection. This time, we went much deeper. We removed the entire Cam support plate with the cams, and the chains, we showed how to replace just the wear item. The spring loaded cam chain tensioner shoe assembly.
We also showed how to replace the inner most cam bearing the bearing in the crankcase. We upgraded to a bolt-in style cam shaft replaced the oil pump replaced the outer cam support plate. Updated that to hydraulic tensioners on the chains, we showed you how to verify cam timing not only cam to cam from the backside of the support plate but also verified timing from Crankshaft to the rear cylinder cam gear to gear with the chain. We showed how to adjust adjustable push rods. We showed how we lift a mechanism, a hydraulic lifts or mechanism works.
We also showed how to correctly cut and remove one piece push rise. We had to put on the battery. Re-install the seat. The front exhaust pipe needed to be removed to access the cam cover, along with the rear brake pedal assembly the rear foot peg and the air cleaner. I started it up.
I did my few preliminary checks. I like to make sure there's no unusual sounds. Whether they be growling or ticking. Everything sounds the way it should. I filled it with fresh oil obviously before we started the motorcycle.
Now that it's been run, I like to give it a few minutes. Let the oil settle back into the oil tank double check the oil, make sure it's full on the dipstick. At that point, you can do a good evaluation, check all the push rod tube O-rings check around the topic block or lifter block areas. The cam covered gasket. Make sure there's no noticeable leaks.
The engine wasn't leaking before you took it apart. It certainly should not leak after you put it together. I'll let oil drain back in, I'll pull the dipstick, check the oil level, make sure it's full. This camshaft upgrade 2005 Dyna, is ready for a test ride.
