commando 1/2 speed shaft support

Find a damaged timing cover.

I have one for servicing my Dominator, it's cut away for accessing both chains. Make sure to avoid cutting off the hole for the timing cover screw directly above the half time pinion shaft.

Imade one from a piece of 1/2" alloy plate, I drilled and reamed the hole for the support (1/2" i think) then with the shank of a 1/2"a milling cutter through the plate to centralise the plate, I spotted through the relevant holes from the timing cover and drilled them to suit the screws. I may have machined a bit away to clear the oil pump. I'll dig it out and post a photo

£19.50 plus vat! that finish must be gold plate.

And the final one, the main hole is 9/16" dia, the cutout on the edge clears the oil pump and on the face the gears. Once the 9/16 hole is centred on the back of the timing cover you can spot the small holes through from the outer edge (ignore the 7/16" written on the plate, brain fart)
