Gear box sprocket for a 59 Chief
« on: January 24, 2014, 12:06:17 AM »
Doe's anyone know where I can get a gear box sprocket for a 59 indian chief? I'm told it was made only for the Chief. I bought one from Hitchcocks and it won't work. I have pic of this rear bird. It has worn teeth and one tooth is chipped. There's 20 teeth. I can email more pics. the file was to large.

Ummmmmmmm.......    ???

I'm not sure who you talked to but ALL the gear box sprockets are the same.  Compare the pic you just posted to the pic they have posted on the link I posted previously.  They're identical.  You will want to order either a 21 tooth or a 22 tooth as the 16" Chief wheel make the gearing extra short.

The Chief was the only big twin to have the 16-inch rims with the big tires. This is likely why it is spaced that far out. It seems I've heard someone mention this on either this site or the Britbike site before. There may be some out there but it will take some time to track an original down. It might be easier to check with a machine shop to see if they can whittle one out and get it heat treated to last a while. It's good you have an OEM part for a pattern. I see a lot of Albion gearboxes for Enfields on the flea pay but you will have to look for the AM series and see if it still has a sprocket thats not worn down too much. Only the Chiefs and the Apaches used the AM gearbox. Most Enfield twins use the H series Albion box. You can tell them apart by the shift cover shape.

Oh man.  Am I going to have this problem with my Chief?  Can a spacer be made to be used with the standard sprocket?

I asked a shop with high tech equipment for an estimate to make one and they said $350. Each additional one was like $40.

I know that there are at least 3 of us restoring a 59-60 Chief right now.  Maybe we can work out a group buy for those sprockets?  ???

I just went out into the shop and looked at a Chief box and sprocket didn't stay to long very cold. But I don't see why you can't have a spacer made to use the new sprocket.  ERC

ERC - Does it look like you can just use a large steel bushing without the splines?

Hi Scottie, It's to cold to go out  and compare but I'm pretty sure as long as the outside diameter is the same size and it fits the shaft tight.   ERC

They make a spacer for the gearbox sprocket on the new 4sp that may work.  ERC

The standard H49 type sprocket will not fit an AM gearbox, which requires an  M49 sprocket. This has a larger internal bore, with different splining, to suit the different mainshaft sleeve in the AM. There is also a deeper recess on the front face of the sprocket to allow the securing nut to fit properly.
The current RE price list on the Burton Bike Bits website shows the M49/20 as available, but I have not asked them directly.
The 16" wheel doesn't overly affect the gearing as the diameter over the fat tyre is about the same as that on the larger-rimmed wheels used on other models.
Incidentally, only some of the Apaches used the AM 'box, others had the 'standard' Albion.

Sandgroper is correct. There is 6 splines on the original sprocket and 5 splines on the new one. So a bushing(or spacer) wouldn't work. I asked Burton bike and they said they don't have it either.
