Rear Sprocket

[rvclz]

I am looking for a rear sprocket for my 1961 pan. Does anyone know of a supplier and part# ? (this sprocket takes the 3/16" rivits) Thanks, RVCL

If you have a independent shop nearby they can order one for you. Otherwise look up J&P Cycles or Jireh online and you can order one from them.

Thanks for the the reply. I have a nos sprocket part#41470-58. This sprocket will not work.
I think HD changed the brake drum and sprocket in late 59 or 60. From 1960 to 1962 the sprocket has a little wider lip and takes the 3/16" rivet vs the 1/8" rivet. I can not find a part number or supplier for this 1960-1962 sprocket. Any help will be appreciated. Thanks, RVCL

My 61 parts books indicates 41470-60 as the sprocket for 60 and 61. Rivet is 8497 (5/32x5/8) ... Perry

Thanks for that part # Perry. None of the parts supplires that I have looked at have that part # listed. I will need to find that sprocket if possible or I might have to purchase a new brake drum. Thanks again,RVCL

NOS sprockets turn up pretty regular on e-Bay. I bought a couple for my 60 and didn't pay much more than the aftermarket retail.

Well folks you're in luck. I have spent the last four months beating my head upside a wall to figure this whole riddle out. Just this past week end I got the final answer, so here goes. Early 58 takes the same old ridged sprocket. Mid 58-59 takes the #41470-58. This sprocket is very similar to the ridged one. It's easy to mix them up on just sight. Now the meat of all this, 60-61. The 62 and up sprocket is identical to the 60-61. The only reason for the change in the number as far as I can tell is the rivets. All the rivets are 3/16" on 62 were the 60-61 still had 1/8" rivets with a 3/16" indexing rivet. I took a sprocket off a 62 and up drum this past weekend and it fit the 60-61 like a glove. You would just have to increase the rivet hole size and your good to go. In Bruce's book he makes reference to the 62 and later having a stamped number instead of a raised casted number. I don't know where he got that drum but the two 62 and up I got here have raised casted numbers. There's no mistaking the 62 and up drum. It has the higher lip on it to facilitate the wider brake shoes. The 60-61 backing plate sits into the drum were the 62- sits on the outside.
Now just when you think it can't get any better! There's more!
The 60-61 and 62 and up brake drums are the same casting #41409-58A. The 60-61 started life as a 62 and up. I can only figure that the motor company was just not ready at the time to make the switch to the wide shoes. So they machined down the 62 lip from .3145 to .1230 and machined a lip into the drum approximately 1/16" deep X .2770 in depth to continue using the mid 58 to 61 backing plate. If you got a 62 drum in good shape, it will only take a half an hour in the lathe to make it a 60-61. Providing you already have a turning arbor for it. Your local cycle shop could do this for you very easily. I sure as hell hope somebody can use this info. It was paid for in stress. Tomorrow I'll post the difference in sizes of all the sprockets and related number for reference since I'm unfortunately stuck with one of each.

Thanks for the info. Thats good stuff.

I was under the impression that 63 was the first year for the wider shoes. According to my parts book there is a 63 part number on both the shoes and the drum. My 62 has the narrow shoes on it.

Robert,
Had you turned the page in Bruces book and continued reading you would have found the following.

Don't you have enough going on in your life right now, with out nit-picking on me?

[Chris Haynes]

I fail to see how giving information that was overlooked is nit picking.
