1925 JD Cannonball Bike

Jerry,
I've attached a couple of photos that should help.
On 1925 boxes sometimes you don't have to do anything but if you have to, grind the necessary off the face of the sleeve gear where I've got the screwdriver tip
You can generally get enough without breaking into the oil holes.
The most important one to check, especially as you have repaired your gearbox, is the sprocket to case clearance.
They run very close and as you generally only put the sprocket on after the rest of the gearbox is assembled it's a pain to find the sprocket fouls the case.
We try not to break into the oil holes and have on rare occassions had to make a slightly longer spacer to get the sprocket clear of the case.
Hope this helps

jerry have you but the front wheel in you fork yet? it looks like you have a 45 brake drum. i always thought that the lip for the dust cover would rub.

Rob Yes it is a WL hub. It doesn't rub but it is real close. I had to modify the hub some to get it to fit. I have been working on it and will post some pictures real soon. The problem is going to be the brake anchor arm. I'll probably have to get real creative.

Tommo Thanks for the pictures and the explanation. I actually was more worried about the other end of the mainshaft and the wider bearing there. I do have an NOS rightside bearing that I could use if need be.

I pre assembled a hi gear and a sealed bearing tonight and it seems if I leave the brass slinger in place I will be within a few thousandths of an inch of the OEM setup. Maybe tomorrow night I can assemble the whole gear in a tranny case and see where it all lines up.

I am in need of the following 2 pieces for my rocker clutch pedal assembly. It is the rocker stand off and the disc that mounts to it.





Have cash or parts to trade. Jerry

Michael Breeding makes the disk or at least he used to. Maybe the bracket too.

I am using CP forged pistons. The clearance must be opened up more than the manufacture suggested clearance (I told them IRON air cooled). I will open my clearance up to about .008" this time, from originally .003", then .006". I don't know where to run Lonnie's pistons other than on the loose side of what he suggested to you. I have scorched two sets of pistons already so I am going loose this time.

Joe Thanks for the info on the clearances. I did not realize my mailbox was full. I cleaned it out. Lonnie suggested +.006" to +.0065". Jerry

Today I received the rocker standoff and the friction disc from Michael Breeding. They are nice but sorry I forgot to photograph it before I riveted it to the strap.

Here it is after riveting.



I also bought the rocker foot 'flipper' from him.
