jb weld for timing pin repair?

[Doyt W. Echelberger]

Hello Scott.....Bottom line: Try it first on your bench and see if you like
it. Test the results before trying it on the vehicle. Whack the model with
a hammer, boil it, subject it to a propane burner, drown it in motor oil
and gasoline, etc.  Just don't blow up your lab.

JB Weld and a long list of other epoxies represent amazing materials if
used within strict guidelines on correctly prepared surfaces.

In your case, if you use JB Weld to keep a hollow cap on a broken timing
pin stub, it should be very satisfactory for years. Or, if there is no
stub, you could use the JB Weld to keep the replacement pin in a hole in
the flywheel, where you drilled out the broken pin.

The key to getting good epoxy results is mainly to mix the two epoxy
components about twice as long and twice as thoroughly as you think
necessary, after being exceedingly careful to get exactly the recommended
amounts measured out to start with.

Right amounts, very well mixed, and then applied at the right temperature
(70 degrees F)  to absolutely clean ROUGHENED surfaces. Then allowed to set
up at same correct temperature over a period of at least a day.....longer
than you think necessary. Make errors on the long side for set up.

You could run a few test batches on your bench, prior to making the repair
on the flywheel. Try to fit a test cap over a simulated stub, and decide
the next day if you want to do it on the real thing.  Or drill a hole in a
steel plate and epoxy in a timing pin, if that is your constraint.  Try it
first ans see if you can do it, and if you like it.
