What to watch for in a higher miliage motor tear down?
 

Well I remembered my friend has his old 13b sitting in his shop and I figured its worth tearing apart to see if anything is re usable. The motor was tested 115-115-115 116-115-113 on a digital tester before it was stored. It has 149k, lost both water and oil seals just randomly.

With out seeing the internals yet, other then chrome flaking, what should I watch for? Bearing wear on the Eshaft? Measuring all the tolerances? I may re use the housings and rotors if they are in good shape.

.....

just wondering, but was the compression test done with the motor cold? That is incredible compression for a motors with that many miles on it.

Yes the test was done with the motor cold, it was removed from the car. Gambone (steve) is the forum memeber and rotary mech who tested it :).

I heard that cold motors read higher compression numbers than hot ones. I think the "hot numbers" are what the real compression is. Dont quote me, just trying to help.

Other than making a judement call on used rotor housings, it's all covered in the manual. :)

Those numbers are good....

Look for excessive step wear where the football shaped oil seal wear mark meets the corner seal wear mark... thats the only place i've really even seen wear bad enough to ditch the irons... Look for pitting of the irons on the machined surface...

Change the bearings on the rotors and the stationary gears and then spec out the e-shaft to make sure its good... if the bearings look good, the e-shaft is likely to be good as well..

Get the Bruce T Video and watch it a couple of times.... he explains everything you need to look for and gives you all the specs
