i looked around and found the dimensions from a thread on here

does any see a problem with using these ? they are twice as long as stock, so you probably wont be able to use the lybaryth seals. im told you dont need, also these are oil inpregnated in case you forget to lube you shaft

Not sure, but you would have to check the cam to be sure it was milled 20 mm deep to take the longer bushing.

Longer would not hurt anything.

Otherwise cut them down to 10 mm long.

Should only be about .001"th interference fit between cam and bushing, so check dimensions when installing. Beating something like a bushing into the end of a cam, like some have done here, leads to cracked cam ends.

Heat cam, cool bushing, helps when pressing in.

Little sandpaper on a long split pin can be used to clean up the inside of the cam before inserting the new bushing.

Good luck.

ya ill double check them before install, i think the cam is bored the same all the way thru. The stock bushing is 10mm plus the lybyrath seal so im sure together they measure 20mm. i got these as they were cheapers then mikes and they are oil inpregenated
