Hmmm.  I see something curious.  Your bike is most probably a '57, but your idler pulley is a solid type (w/ bearing I assume).  The parts catalog I have (from '56 or '57) shows the 2 piece sheet metal idler pulley replacing the solid one.  My bike, which is earlier than yours, has the 2 piece one.  I guess it's entirely possible that one, or both of our bikes have had replacement pulleys installed over the years It's a pretty small bearing.

I just glass beaded my pulleys.  Do you guys apply any type of clear overcoat paint on them to keep them from oxidizing?

I did clearcoat aluminum parts on a 59 apache truck seems to hold up good

Ok, here's another question.  The return springs in my transmission are about a 1/4 inch shorter than the ones on the rear brake shoes......even thou they have the same part number according to all of the parts catalogs.  Anybody have any ideas?  Now I'm not sure which spring is correct for the transmission clutch.  Both springs are of the same construction, so I don't think the previous owner swapped in something different.

Here is a measurement on one of my brake springs,I have clutch back together already I didn't notice a difference ,but never layed them out together

[Mike Sal]

Finally remembered to measure & photograph the different springs on my rig.  I'm pretty sure the short ones were in the transmission & the long ones were in the brakes, but my memory is getting fuzzy.....

Anyway, I'm wondering which is correct for transmission?  The parts catalogs say it's the same spring for both, but which length is correct?

Talked to Wayne today & he says only the earlier bikes used 2 different springs for brake & transmission.  This plays into my suspicion that my rear wheel isn't original to the bike (the hub had a lot of rust pits while the rest of the bike have virtually no rust and the springs are 1/2 inch longer than the tranny springs).

Mike, after seeing the pics of your longer springs iam sure I didn't have any like those . It is a pretty noticeable difference.

[Mike Sal]

I was concerned about it, as I think the length & quality of the clutch springs has to affect the engagement speed of the clutch.  You don't want too early or too late engagement.

maybe you guys should just trade pulleys !

Hey guys Jeremy here could someone tell me if I need a spaced here belt doesn't line up just right rubs on inside case , thanks

Jeremy, according to the parts diagram posted on the previous page, it says you need a washer, part #3354. 

Would I be correct in assuming the bearing ID for the fixed pulley is 10mm and fits right on the axle shaft?  The reason I ask, is when I replaced my bearings the hole was 17mm. I thought I had the wrong bearing but when I went to look at the clutch on my 54 it has machined spacers inside and out.  (Pictures below)  I made another one for my 53 and all is good.  I could not find this part in any manual, so I'm not sure if it is stock or not.  Anybody?

[mywaymfg]

Rick, iam pretty sure my hole in the bearing was the bolt size unless I didn't notice the bushing/spaces I never messed with that bearing, I answered my own question after looking at that diagram I put a washer in there that I had laying around belt clears but is very close.

it sorta looks like everything (including the pulley on the crank) need to shift to the left a little doesn't it.

I'll have to look in my baggy-o-parts to see what washers/spacers I have.  I just slid the axle & everything into a bag when I took it apart & haven't cleaned those parts up yet.
