Product Details

The 34091-85 inner bearing race has been used on Big Twins since 1985. The inner primary bearing rides on this race. By design, this race press-fits onto the transmission mainshaft. This system works fine for stock engines. 100 HP+ engines will make this bearing walk on the mainshaft. If it walks inboard, it will damage the maindrive gear seal and cause a transmission oil leak. If it walks outboard, it will cause a primary oil leak. Our high torque bearing kit eliminates this condition. Kit incl udes a precision honed bearing, Seal & One (1) Circlip

Tech Tips:-

* Fits 1985 – 2006 and early 2007 models with 25mm mainshafts.

* Will NOT fit late 2007 – early 2008 with 24.8 mm mainshaft.

* Only fits models with (2) two Original Circlips ie. One(1) either side of the original bearing.
