4 speed transmission output gear bushing direction ?

Plan to replace the junk gears in my Revtech transmission with a set of good condition used original Harley gears. One of the first things I will be doing is get set up to press a new bushing in the output gear. I need to find out what direction the bushing go's in the gear. There is a counter clock ways thread that go's in about 3/8" on one side of the inside of the bushing. I need to know witch way it go's in the gear. The threads to the inside of the transmission would help pull oil in to the bushing an on the sprocket side it would still be working the oil in the same direction.

Well witch way does it go . Thanks Guy's

The grooves go to the outside (threaded) end.They act as an oil deflector .Note that that bushing must be reamed after installation.

OldBob!

Don't forget to torque a sprocket and spacer on it before you bore, or ream and hone-fit it for the mainshaft.

The bore distorts from the torque.

I use a piece of chain on some too-light channel stock for holding the sprocket. Beware that a vise will distort the bore as well!

When you release the nut after fitting, you will find your bore tightened up a bit on one the slinger end, but it will go back to "straight" when the sprocket is finally installed to the same torque spec.

This will assure the longest life for your bushing, as well as optimizing the contact of the slinger portion.

Good luck!
