For the inner primary bearing I skipped the balancing act on the press and used what I had.

Put the inner in the wood vise and used the trans tool kit to remove the old roller bearing and install the new Baker Hi-Torque bearing.

I used these tools.

This is the original HD trans sprocket spacer next to the new Baker spacer.

From Baker's web site

sprocket spacer

If you are a seasoned technician, you have seen a severely worn sprocket spacer. Over time and miles with dirt and grit, the stock 33344-94 spacer is too soft and it gets gouged by the seal that rides against it. As the spacer gets gouged, the seal relaxes. When the seal relaxes, the leaks begin. Our sprocket spacer is a direct replacement for the stock spacer except ours is case hardened steel that has a Rockwell ‘C’ hardness of 55. No more gouging, no more leaks.

Whether you agree with the hype or not, the Baker part is cheaper then the HD part. And the the recess is cut into both sides, so it can be installed in either direction.

I strongly suggest - that if you install the Baker Hi-Torque bearing - that you test fit it before installing in the primary.

Brian and I both got this bearing from the same vendor, ordering within an hour of each other.


His fit fine - mine did not fit!

Baker acquires these bearing and then hones out the inner race to .9858 +/- .0002 (on my receipt).

apparently my bearing missed the QC.

Baker immediately sent out a new bearing and I had it in 2 days.

Nice job Duane, thanks for the great pictures along the way, really great that George's Garage sent the new plate with no hassles, good customer service!

Yes, great service.

I could have just straightened the plate that I bent, but, the area where it bent is already a weak spot (recessed hex) and once you bend a piece of metal ......................

So, I did straighten the plate, then drilled both pieces and tapped the original plate.
Now they are doubled up and should not bend any more.

I still don't know if the case broke first or the plate bending pulled the bolt out and caused the problem.

Two version of the primary drive holder used to remove the comp and clutch basket nuts
The Jim's tool, a plastic stepped wedge is sitting on the primary above the comp sprocket.

Georges Garage sells the flat bar stock that you jam between the sprockets.

With the large Baker comp sprocket (28 teeth) the bar was a little tricky to use, but I like it better then the plastic wedge.

Ever wonder why the oil can spit back out at you while adding to the tank?

The fill hole is a little on the small side underneath the oil fill cover.

Baker supplies a bottle of Spectro 6 Speed gear lube with their gear kit.
The bottle holds 23 ounces, just right to fill up the trans 

I contacted Spectro to see if the smaller bottles were available. They are specially packaged for Baker and not available on the market outside of Baker.

I pulled the case out of the frame from the right side per the manual.

Would not go in.

I had to remove the exhaust bracket and install it from the left side. Part of the problem is the bigger pan. (I found a great deal on this and that will be in another thread).

It's in the bike, and the bike is running. On the jack the trans shifts smoothly and easy.


Running in the garage with no load on it I couldn't tell if it was quiet or not.

Excellent.  Best news yet.   Congrats on getting her done Duane.

Great news. This has been very informative. Great posting!

Opposite side with cup to allow gear to press into bearing. This part of the tool supports the inner race as the gear is pushed through.

Thanks for sharing this ordeal with us, Duane; great stuff! It appears from your photos that the Baker setup uses the OE single row ball bearing for the main drive gear. I’m a little fuzzy on this, but I believe that Milwaukee went to a double row ball bearing in this application to accommodate the additional thrust force generated by the helical gears. Is that MDG bearing a single row ball bearing?

The Baker replacement bearing was similar to the original

Knew it (install) would end on a positive note.
