It must be a solid spacer. I could have swore after I pulled the seal out that the spacer was on top of the bearing. But that's not possible. Any difference in setting preload with the solid spacer? My Snap On buddy is sending me his torque wrench to measure the preload.
More fun stuff today.... Got home with the parts and found that I have a modified pinion support. The inner bearing is larger then the outer, standard size. Had to call every place in town today to find the right bearing and race. Doesn't anybody carry fricken Timken anymore? Geesh..
Tex Racing, which built the diffs for Panoz, has a pump that fits inside the diff. That's what the GTS cars have. Less plumbing and it's driven off of the pinion. The cooler is not in the budget (time or money) right now. I have not heard of another GTRA or GTWC with diff problems due to heat so I'm going to leave the cooler out for now. I would think that failing diff seals would be the first indication of a heat problem. My seals are doing fine. No
oil in the tubes or wheel bearings. If need be I will add the external electric one later. The importer of those electric pumps is right around the corner from my shop.
