Seal wear on shafts

[johnnythunder]

I Purchased a Chrysler 1057hc last summer and when Was checking the impeller and seals in the lower end i noticed some seal wear on the prop shaft and drive shaft can this be repaired ? would it be cost effective ? are shafts available and are they expensive how about a decent machine shop can they weld and machine on a lathe without ruining the hardness?
Thanx Johnnythunder

Why?

if you pressure test it and the seals are sealing then why go to all the trouble of removing the shaft? The shaft seals should be spring loaded so that they do not need an exact diameter.

have not reassembled yet wanted to check around before reassembly for a what if scenario

Re: Seal wear on shafts

It depends on how bad the wear is. I had a prop shaft seal leak that was not revealed during a pressure test. When the shaft is spinning is when it was loosing its integrity. You can take it to a machine shop and they can fill then re turn the shaft. I had this done with one of the gear housings I had but never got a chance to test how good it was. I sold the unit. If it seals dont do it. If you get it back together and you are sure it is leaking there have it done. Maybe before you put it back together ask a couple of machine shops what they think. With as bad as the economy is now you should be able to find someone to do it for you for cash.

Re: Seal wear on shafts

I don't know model numbers and how they relate to years. BUT: if you have a chrysler earlier that 1979 with a two piece lower unit, be absolutely certain that the end float of the propeller shaft is correct at .004-.006. This shaft is carried in a tapered roller bearing. If it has too much end play, the bearin will be too loose, allowing the shaft to wobble in the seal. Under these conditions even a brand new seal on a perfect shaft will leak.

To check your shafts for excessive seal wear, check the wear groove. It should be shallow and polished. You should feel it but your nail should ride over it nicely. say around .002 would be acceptable and a new seal will adequately prevent leaking. If it is rough, or deep enough that your nail would catch in it, it is no good.

bearing supply stores sell generic sleeves that fit over shafts, repairing damage yet using the original part number seals.
