The FXS Shovelhead rebuild project

[jcrubin]

This was completely unnecessary, as the retaining plate captures the outer race of that ball bearing, preventing it ever spinning. The mounting cup or sleeve is not a race, and is normally a slip fit on the bearing. As it is a light press into the case, it will tighten up a little on the OD of the bearing when all is installed in the case. What you did certainly won't hurt anything, but you didn't gain anything either.

Yeah its true the plate prevents slipping, but anything press fit that 'falls' into a race is not fit as prescribed regardless. The remediation was still more prudent than leaving it alone. If the extra 5 minutes of work to do this was unnecessary, guilty as charged i suppose.

Is this on the timing side? I don’t know much about cow pies as I threw mine away and opted to build a ratchet. But that bearing/race fit was the only thing that held the mainshaft from walking to the primary side and would completely slack my clutch when it decided to. Took me a lot of tear downs to figure that one out

Please be more specific..

I just noticed this were you asking me???

The bearing retainer plate holds the bearing in place. If you have a mainshaft walking, the shaft nut is loose or stripped. All four speeds are set up essentially the same, regardless of the shifter top.

The nut keeps it from walking towards timing side but nothing was there to keep it from going to towards primary.

Edit: I probably have things backwards a bit here. Been a while. But the retainer still allowed enough movement for the mainshaft to walk, a tight race and bearing solved it.

Assembly of the countershaft was staged but there was a sizing issue with one of the bushings


This one was just too big to fit


J&P was happy to send another bushing NQA.

Sadly, having some personal family issues, id taken some time away from the project.
Back at the bench a month or so later, I confirmed good fitment of the bushing.

I decided to measure the OLD, NEW, and REPLACEMENT out of curiosity

OLD 1.6891


NEW 1.6911


REPLACEMENT 1.6893

A Fine fit with independent rotation of the gear and bushing on the shaft.


Retainer clip and further additions


Full Assembly with outer gear
