Back in the beetle days it was somewhat common to have to remove that drive shaft to "adjust or add" shims to get that gear in the correct spot to lift the fuel pump rod. I have seen cases where no shims were installed that case wore enough that the shaft didn't reach the drive slots in the distributor. I take some finesse but the drive and shim can be serviced with the engine together. A little grease will hold them until the drive is in place.

Hi .. as you know now, it's very important to not take out the distributor drive ever.. and to always keep a distributor or something in the the distributor hole to keep that shaft from lifting up if you turn the engine.

Evidently you have the shaft in now, with some washers. I'd say your only choices are to run it and see what happens, or take the cases apart to replace the damaged brass gear on the crankshaft.

yeah, what easily happens is the thrust washers lift up, and jam against the brass drive gear .. if you do anything other than keep a distributor drive shaft well seated down into the engine and a distributor or something to keep the shaft down in there.

if you have the cases apart for any reason, what works really well is ..the whole time you keep a distributor in the left case half.

and I know that 'forever' all books have talked about installing that shaft later.. when what is really smart is you put the distributor drive shaft and a distributor into the left case half first thing .. even before putting in the crankshaft. it has to be aligned right too of course.

bummer ..now it's either see how it goes knowing brass shavings got loose.. and wondering if the brass gear will fail completely or what.

'Heart breaking grinding noises' does not sound good.

sounds to me it's like split the cases or take your chances.

let us know what you decide ! Scott
