I'm looking to buy a Bosch distributor drive gear (11 tooth) that goes on the end of the cam. Thanks : Bruce
For a front plate or a clip on distributor?
Dan, it's a "clip-on" I think. The dist. mounts on an extension or adapter that locates in the same place as the original timer. Mac's sells the correct gears in pairs only and I just need the 11 tooth drive gear, not the driven gear on the dist. shaft extension. I think it also requires a special locking nut as well that I don't have as yet Thanks : Bruce
The lock nut is the standard lock nut used for the roller type timer. It also needs an 1/2" spacer between the gear and cam.
You need to get the gears in matching sets. Over the years I have come across several different elevated timers and distributers and they all seem to have different gear designs - Bosch - 2 types at least, Attwater, KW + other aftermarket makers.
The Bosch distributors uses one design for the front plate style and one for the clip on. The one he needs is the one with the key way cut in it for the clip on.
I don't make the Bosch clip on gear sets, so I'm no help. I have a good supply of Front plate cam gears if anyone needs only the one gear.
FYI, the front plate gear are also 11 tooth.
