Hand crank slipping


Recommended Posts

1928 standard six

 

Hand crank used to work ok, now it just skips over the teeth. How tight does everyone's hand crank fit the drive hub at the front of the crankshaft? Mine has become unusable because it slips so bad now. It was ok, but just got worse and worse. Not sure if it is correct for the car or not. I'm wondering if I knocked all the rust out of the hub it engages and that had caused it to loosen up and not engage correctly.

 

Can anyone upload a pic of theirs for comparison?

 

Does the drive hub come off the front of the crank if I need to file it back into shape?

Not sure but I think this is what you are looking at.

 

Crankshaft end.

Handle end.

I have a four cylinder DB so not sure how easy it will be to access the end of the crank to remove / replace the end piece on your six.
Probably best to try to find a better handle too.

Is the electric starter not working.

That is very similar to mine. Thanks. So the nut should just thread off then? I will try to re-grind it back into shape

Yes, it should just screw off however being on for nearly 100 years it may take some effort.

I am not sure that a grind would work, perhaps rebuild with weld first or replace with a better one.

Got it off without too much issue. Obviously worn. Going to see if I can repair it. Handle and nut need work. Weld up and grind down. Luckily I have machinist friends! I could try myself, but they will do such a nicer job
