you have hydraulic, 06 and forward all HDs had hydraulic

 

When you see a lot of pitting, its from high speed oil cavitation.
Seen in in the big cruisers. Mine at 30K (my last check) had very little. At 10 years, delrin get oil heat brittle and even the roller chain ones that only wear until the rollers hit and then they roll can break from being brittle.
The non OEM are just white delrin. Problem is you need to be careful removing the rivit and using old spring. Screw that. Harley has them 120 for both. Get the guide for 5 and two new retainers for 3. Ronnie's H-D.
Would also replace inner cam bearings if you don't know how to inspect them. I have a plug and just look close at them. Replace o-ring in pump and check end play.

 

IIRC 96 engines are hydraulic, 88s are spring. Last few years of 88s the pad material was improved I read.

 

Harley installed them from 99-2006. You can buy them

 

WTF do people open their trap on here?

2007 for touring bikes. I believe the dyna got them in 2006.

 

Lol Zerk,,,,,are you a Harley tech or something? I used to be service manager at our local joint in Massachusetts,,, a mostly Jap bikes but my tech I had worked on Harleys all the time because of his love for them,,,He taught me quite a it back in thos days,,,Most harleys have changed a tad since those days,,,,

 

Not a pro. But not some new guy not paying attention, telling people stuff that is not true.

 

I don't think so Ripsaw. The divots I've seen were almost invariably rounded and smooth. They look far more like internal air bubbles to my eyes.

I've been around plastic molding some, especially at B&D. Air entrained in the mixing or the injection process are common causes of this, and overheating the plastic can also do it.

 

Looks blasted out to me. Not sure how the link could weld on and rip it out. We never cast Delrin, so no experience with that. We go it from a supplier in blocks. Different colors and grades for applications. We used it for mask bearings, rollers and a lot of other items on Subs.. Heat-treated it in hot oil baths to add hardness to it. All are grades were premium. Never saw any surface like this when we machined it. That second shoe is off a roller chain and why it only wears till it starts rolling and will last life of motor unless it breaks from age.

 

Whatever you do, just make sure you swap them when its needed and don't let it lapse. I had an '03 Ultra Classic that I acquired on trade that supposedly had the entire motor redone less than a year before I got it. The tensioner took a crap on me 50 miles outside of Laconia two years ago on the way to bike week and grenaded the whole motor. I would say if cost is an issue the spring ones are ok just check and replace as needed. I wouldn't wish what happened to me on anyone!!

On a good note that's how I ended up with my '11 Classic!! I bought it up in NH!
