The FXS Shovelhead rebuild project

[jcrubin]

I'll bet if you get the grease or what ever out the holes they will be round enough....

Just remember when your remounting/bolting down the motor it might need to be shimmed and you should mount the inner primary to the trans and motor before anything is tightened down.....

Definitely true i agree, This motor installation will be done correctly.... not like the crackhead who did it last. Im just concerned that the motor itself is supposed to be stationary and everything is supposed to align to it. It cant be stationary if the holes are too big... I might be overthinking it.


I have only a few items left to remove to send the bottom end off to the machine shop...

Not really.... The motor should be level and not twisted or tilted in the frame..... Then bolt the primary to the motor and trans before torquing anything down..... Make sure everything is sitting flat to each other..........

What tattooo said, and I will add something...
Once the inner primary/motor plate/whatever is bolted solidly to the motor, make sure the assembly is straight, i.e. parallel, to the driveline (frame, wheel/sprocket/etc)
There is typically a tiny bit of wiggle room with the engine mounting, so just eyeball it and make sure.

Also, when shimming the motor bolt the rear mount first to determine if and how much shim is needed, and if the motor is out of whack.

Btw, sweet looking bike. Not many around that are that stock looking anymore. Mine (81) sure isn’t, but then they were plentiful back in the days when I did all my mods.

All that is left is to throw the cam back in and close the cam cover and its off to the machine shop.....



Oil pump removal



Oil pump 2



Oil Pump 3

[Tattooo]

How does it look inside where the gears run in the pump???

[jcrubin]

I found no issues or causes for concern with the oil pump, I will be doing a closer inspection of the gears in place once i get the case out the door and bench space available.

Thoughts on this? I can't see going for 200$ for JIMS for something I use every five or so years....

It should work just fine....

I have bought several specialty tools from this supplier. They are good as jims.

Some say this is a sign of a loose sprocket

You may be dealing with hi-wear on the main-shaft and fourth gear inner bushing....

Try rocking the sprocket with two screw drivers or pry bars....



This will give ya an idea of how much the bushing/bearing is worn ...

Looks a bit tried to me....

Wouldn't be a bad idea to fresh up the tranny with new bearings and bushings, most likely a new mainshaft will also be needed.
Might see some other parts that are on their last legs while yo're in the belly of the beast... Shift Clutches takes a whooping and the forks are hi-ware items...

The tranny I can do in house....

Im gonna new a few extra specialized tools to do the complete job though. I hope to get the engine off to the machinist this weekend then I can put the tranny on the bench

[jcrubin]

With the bottom end at the machinist, I had time to pull the tranny
