I bought this timer and roller off Ebay. I see no markings on either. Are they original Ford parts? Does anything go on before the roller? Washer? Spring? What should I use to hold the roller on? The right size split pin? Should I clear coat the outside of the timer to prevent rust? Thanks.
There's a pin that goes through the notch into the shaft, then a cap that holds the pin in place, then a nut. Lang's part numbers 3207, 3206, 3220.
All the photos are out of focus, but it looks like a Ford type timer, although not made by Ford. Maybe Tiger or some other brand.
It looks like the roller has its spring, but I can't see the condition of the body and can't tell whether it needs any repair. I use satin black Rustoleum for chassis parts like this, but clear coat is OK.
Does the front cover have an oil seal? If not you'll need one.
These parts hold the roller on the shaft:
A little pin holds the roller on the shaft. I shorten a small nail for this.
This cap holds the pin in place.
A lock nut holds the cap.
It appears to be either a Tiger or Bulldog brand timer. It is pretty egg shaped inside. May or may not work OK. A good Tiger timer looks like this inside:
If it were mine I would true it up on the lathe on the inside before packing it with grease. Like this:
Another blurry pic but I actually did find FORD on the roller. I don't have a lathe so I will probably try the timer as is.
If I were you I'd by a new one from Lang's. Like Royce said that cap looks pretty egg shaped, the chance for bad contact and sloppy or poor firing is not worth the time for the experiment.
I don't think it's a Tiger. They used a cheap oiler cap. Royce is probably right on the Bull Dog, but there were others. If you are using a felt up front, don't forget the commutator shield which was not mentioned above.
