Pan engine advice..

#1

Post by George Greer » Sun Nov 07, 2010 7:24 am

Hi, all..

I will be soon the new caretaker of a 1958 FL engine.

Any tips, advice..items to look for, during teardown, inspection, repair and assembly of a 58 engine?

I have access to a NDI lab at work, and can do Mag Particle, Eddy Current, Ultrasound, and FL inspections (no pun) on the parts.

I have also been researching here and other boards, about the engine valve seats.

Are they a particular item of potental trouble? That is the general gist of what I have been reading... OR am I just paranoid?

Thanks,

George Greer

Well, one help on paranoia is get a shop manual and riders book for the 58. Then, from there you go to this forum or other sources to clear up anything you cant understand or dig in the manuals or if something is missing. No shop manual is thorough enough and usually you need to find a panhead nut like some of us and ask....To submit a list at this point is difficult and there will always be items not mentioned till you come across them. Carb experts, generator/electrical machine work fall into more catagories you need to address when in there. Then ask around.Hard to generalize at this point......Joe

Joe..

I'm sure your correct, but just looking for general info.

Places of special interest on these engines, that may be of concern.

Everybody has their own pet pieves that that like to take extra time/special considerations when going over a engine.

Thanks

George

George

Panheads used bronze seats and when worn severely, they can go to headwork people like Headhogs. There are others but I think Headhogs pour the bronze seats back to original. Localy, I have had seats pressed in and no problems so far but others have a lot of grief in that area. Unleaded seats and plain seats are available in all the big catalogs like V-Twin, Custom Chrome etc. Info like that is not in the original shop manuals so most all components will be rebuilt useing proven modern methods, sometimes aftermarket parts and there are a few common favorite brands in these catalogs. Original parts are getting used up fast. Its all gonna be a wide open field and a lot of different opinions to drive ya up the wall sometimes as to whats best. Good luck and am sure there will be alot of input and opinions/advise on your thread here...Joe.

The usual crack from the pinion race to the cam bearing.
Rockers probably need rebuilding.
Very common for the head gasket surface to have shrunk, leaving the star inserts exposed - which blow gaskets.
Bad exhaust port exterior.
I don't know how shop owners put their children through medical school before seat replacement was invented.
