starter grinding

Starter’s fine… I have tried 3 altogether, and same problem.

I think I have a clue though… cut a window in the bell to see the starter/converter area. It appears I have a converter that has too many teeth, too close together as the Bendix teeth wont mesh with the ring gear teeth. I have video of them not working together, but the forum won’t let me post it.

I was under the impression that 904 converters were all the same up to ‘67, which this one is as it has the small hub?

OK, and I thought that I had mentioned to you before, but it was on another site.
OK the early 904 had two converters. Engine does NOT make any difference.
From 1960-Early 1962: 11", narrow ring gear, no weights, 1.550" pilot, slotted hub 18 splines. 148 tooth ring gear.
From late 1962 to 1967: All the same as above, except for the >>> 122 tooth ring gear<<<
Just a point: The hub is the part of the converter that goes into the pump, and the pilot goes into the crank.
This should tell you which converter you've got. Personally I think you've got the Early converter.

Hope all this helps you.
