TC 88 Cam Chane Tensioner Fix
#35
A lot of people believe the TC88 has an insufficient oil pump; when actually in it's early development it had a problem with too much oil pressure in the crank case.
If I were going to install a hydro tensioner kit I would install the higher volume oil pump because there is an additional oil circuit (the two tensioners). When I replace spring loaded tensioner shoes I install a Baisley LMR-2 oil bypass spring which increases oil pressure at idle. In my opinion, nothing more is needed. I learned this from some the most knowledgeable people on this forum.
As far as the Harley hydro conversion kit goes, it retains the link chain on the back side of the cam plate and isn't a proper fix for tensioner wear. Were I going this route I'd build my own kit with conversion cams that used a roller chain on both sides of the cam plate. I didn't understand how Harley's conversion was poorly designed until I had one apart for the first time. For what they want, it's kind of criminal.

Still running the original OEM oil pump in my 16 year old bike (with 160,000 miles on it.) I didn't even touch it when I did the gear drive cams back in Jan '11 when she had 81,000 miles on the odometer.
Harleys don't need higher pressure. The only benefit that I can surmise would be if it's a hot running bike, circulating oil faster through it might aid in cooling it somewhat more efficiently. (Theoretically.)

Lot of great info on here as usual. I did do the whole HD conversion on my newly acquired 06 Deluxe with 31k miles on it. I spent around 1k doing the whole deal. On my wife's 01 FLSTF I only did the tensioners and it has 60k on it and runs perfect no issues. I have also heard and read the conversion kit is not all that great as well. So it appears my son is only going to do the tensioner (Cyco) and new cam bearings. However we are having trouble finding anyone who actually sells the Cyco tensioners. Any body buy any and from where? As always thanks for all the great 411 guys!

Ebay for the Cyco shoes. I have the Cyco pin tool and it makes changing the shoes easier but it's not totally necessary.
Here's a link to an auction of a set with the tool.

I'd do the B148 inner bearings and if you're gonna stay with spring tensioners I'd look into the tool that removes the inner with removing the cams from the plate. (link in a post I made above).
Consider the Baisley LMR2 spring. Not necessary but it does increase oil pressure at idle.
Depending on miles maybe lifters, if you have the old B lifters I'd stay with them. What I wouldn't is cut the push rods and install adjustables. Most of the time folks encourage that but it really doesn't save a lot of time and it sure doesn't save any money. Go thru the top and update the breather system in the rocker box with the newer style for like 12 bucks each.
New O rings for the oil pump and gaskets and you're good to go.
