If they are for your 89 FL does it not already have the gear drives.

Forget all that stuff below. Wasn't thinkin'!! EVO!

You have a gear driven system.

CRANKCASE - GEAR SIDE - 1989 Harley Davidson FLHTC-U




This info is for guys with TC and spring loaded tensioners (i.e., pre-2007):

Wrestled with this issue myself. Here is the saga:

Cam chain tensioners - running on borrowed time! - Harley Davidson Community (Cam chain tensioners - running on borrowed time!)

OK, then the links I included in my post above do apply.

With that large an engine, runout is a key consideration. If your buddy had the crank done (balanced, trued, crank pin welded, trued), then the gear drive option may be safe. As indicated in the link, I do like the gear drive best, but runout was the worry for me.

Re: Gear drive cams vs chain?

I've got gear drives in my Wide Glide. Seem to work fine. They are noisy though. If the kit for the chain drive upgrade had been available when my tensioners had problems I would have used it. I'm not going to replace my gear driven but I would recommend the upgrade to the chain drives.

I had 16,000 miles on the bike. One of the tensioners was at the point of failure. The other was well worn. Wish I had taken some pics of the wear.

Running gear drives on both my bikes; a 95" '05 FXSTD and an 107" '02 FLHT. I like them; no problems; they don't increase performance, it takes horsepower to run them just like the chains; not noisy if set up properly; Andrews makes them. The new hydra chain conversion was not available when mine were setup but had it been, I would have gone that route if for no other reason, the new high volume oil pump.

It takes time and attention to detail to set up gear drives properly to insure that they are not noisy. Properly setup gear drives won't make as much noise as the old Morse chain setup; they are noisy.

Smile Re: Gear drive cams vs chain?

I would go with gear drive; i spoke to a s&s rep at daytona this year and he explained the series of steps to make your gear drive cams quite; the run out is the main thing and all the parts that have to be changed out. It can get very expensive.....
