Koyo, needle bearing camshaft. 'Full needle'
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. OEM replacement reference 9058, 9058A

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)
Cam chain tensioner, outer
Chain tensioner for the primary (outer) cam chain drive. OEM style replacement. Compatible with the early Twin Cam models equipped with spring loaded chain tensioners. Note: See 921173 for the secondary (inner) cam chain.

Andrews, cam driven gear kit. 34T
Grear with keyway. Incl. bolt, key, washer and three spacers. This Andrews 503576 gear is an improved design over the OEM style gear for 1999 only Twin Cams (which is no longer available from OEM). The 1999 OEM design is prone to broken woodruff key's, when this happens the cams, and complete valve train, will stop in the still running engine. The Andrews gear and spacer is made from a 4 times stronger material than the OEM gear, and is of a one-piece design. This one-piece design enables the use of a full length .350" longer woodruff key, which improves strength. Note: Especially in high performance applications it is recommended to use the Andrews 503576 gear for 1999 Twin Cam models.
Fits: > 1999 Twin Cam (NU)
Andrews, EV51 cam .510" lift

OK for hydraulic lifters and springs. Note: Small base circle cam. Adjustable pushrods, or longer pushrods, are required to gain extra length to compensate for the smaller base circle.
