Koyo=former Torrington. When still present it is advised to replace the low cost OEM needle bearing in 92-99 Evolution Big Twin models marked 'INA SCE 138 USA' with a 'full needle' bearing to increase reliability. Especially important when using higher lift cams, which increases stress in the camshaft bearing.

Replaces OEM 8990/A style ball bearing. This bearing will fit will fit all models as front & rear outer cam bearings. Note: The MoCo has redesigned the Twin Cam rear outer cam bearing from ball to a roller bearing style in 2001. This was done to help prevent failing ball bearings on, specifically, rear (=driveside) cams that are heavier loaded. This 01-up roller style bearing is a 3-piece design that is more heavy duty than the roller bearing. No other parts changed during the bearing changes. The early 99-00 style ball bearings will still fit all 99-06 models front & rear. Using front & rear ball bearings present no issues on cam driven gears.
Fits: > 99-06 Twin Cam (excl. 2006 Dyna) (NU)
LOCKED THRUST WASHER, CAMSHAFT
With 'ears'. Fits against the crankcase, behind camshaft. This is the locked 'early' 58-90 model for which a separate thrust washer shim is used to achieve correct camshaft end-play. It is also used in virtually all aftermarket 58-99 single cam engines. Note: For 91-99 OEM cases the MCS 906636 thrust washer is used, which is not 'locked' since it has no 'ears'. For this thrustwasher shims for correct end-play cannot be used since the thinnest is already too thick.
Fits: > 58-90 B.T. (OEM CASES); 58-99 B.T. (AFTERMARKET CASES) (EXCL. ALL TC)
