I'm about to do my winter project, which is putting an EV27 cam into my 99 Springer, but I have an interesting question about the size of the cam bearings.

Is the Evo cam bearing the same size as the twin-cam bearings?

I've a couple of brand new, still sealed S&S bearings for a TC & wondering if I can use one of them in my 99 Evo motor.

 

No, they're different,

 

Check the part # because Timkin makes a repalcement.

 

TC are way bigger.

 

Yep, they sure are. Bummer.
Oh well, the Springer only has 6500 miles on it.

 

while your in there put a new on in it. Easy job and piece of mind

 

True.
Gotta hit the shop to get the shim anyway.

 

That 99 probably has an INA inner cam bearing Replace it with the old Torrington inner cam bearing P/N (on Torrington bearing outer cage ) B 138 Special bearing extractor and installing tool required I use a Trock tool (out of business ) others available

 

I recently replaced my cam bearing in 1991 FLT and used Harbor Freight blind bushing puller and bushing driver kit. No problem. Before installation, I froze bearing and heated area of case with hair dryer. Went in easy.
