What are the chances that the harmonic balancer that i plan to reuse form and older 235 (53-55) will work on a newer 235 (58-62)?
and there is a decent groove worn into it by the old seal over the years. I have a new seal in the timing cover whats the chances that it won't leak?

I neeed to heat it up and drive it on right?
thanks Mike.

not sure about years of application, but someone will ... and there's a thing called a 'speedi sleeve' available to take care of the wear groove, use one or it will leak

If you have a 53-55 truck harmonic balancer it should be OK on a newer 235 that has a 3/8" fan belt. Use the fan shroud with a diameter that matches the engine/generator.

A worn area on the crankshaft snout where the cover-seal rides can be easily remedied with a "speedi-sleeve" or other similar repair sleeve (Rockauto.com as one that presses on and needs no adhesive/sealant).

No you don't need to heat it up to install it. You need to drive it on with a big hammer.

I used this speedi sleeve on my 1956 235 engine.I used a block of wood and lightly tapped it on with a mallet.I used the sealant that came with it.

I just put a piece of mechanics wire behind where the seal seats in the cover, to shim it out a shade. That way the seal rubs on a new spot on the balancer that isn't worn. I guess you could call me a tight butt !!!!!

What do you think you're hammering against?

Yes, it's the thrust bearing.

I used some thick gasket material, cut it to fit under the seal that fits in the cover, to shim it out, also. Used some gasket sealer on the gasket material and it sealed it and shimmed it out. The gasket material is about 1/32" thick.

thanks Mike.

I warm the hub on a hotplate so I can install with oven mitts instead of a hammer. I have a speedy sleeve on mine but it's mighty thin and think moving the seal a bit would have been a more permanent solution but have no leak so far.

Also, welcome new guy from Hurst, Texas with 3 posts???

I have a 216 and there are threads inside the crank shaft. You can put a threaded rod in the crank shaft and use a nut to press the harmonic balancer pully on.
