source for taper pins - Erich - 20-01-2025
Hi All,
I'm on the hunt for taper pins for the gearbox levers which push on the bearing carrier to disengage the clutch. I've asked a couple of cherished suppliers who don't have these. I'm having some difficulty finding them here in the US. I think they might be No. 3 taper pins about 1.25 inches long. But I don't know what size the small end should be or how to determine the taper. The Austin part number is BH 85. As well, I need to source the washers/spacers which go on the lever shaft. These are part numbers BH87 and BH88.
Any sources are much appreciated.

Thank you, Chris. That's a start. But I don't know the specs. I think they are 7/32 so I think that would be a number 3. And I think the length is 1 1/4 inches, but since they are both buggered, I'm not exactly sure. As well, I don't know the diameter of the small end so unsure on exactly what I'm looking for...I've tried wiring the Austin Works at Longbridge and have yet to reieve a reply. ;-)

I find Simply Bearings are pretty good for many of these mechanical parts

Not sure how their service stacks up in Washington state

You haven't read far enough down the thread Erich - according to Steve it's 7/32" x 1 1/4" (imperial type).
A possible supplier is also mentioned.

That is the correct specification, Chris. Important, as I said then, that the taper is Imperial and not Metric and for Imperial taper pins, the dimension (7/32") is taken at the large end. All the information needed to specify the correct pins is there already!!
