According to Beaver at Winters QuickChange rear ends, " you don't need no stinkin rear end pump to run five miles, unless you want one more do-dad to chance screwing up".........Bob, who spent three grand there and was talked out of a pump.................

  Bob   What did Beaver recomend for oil in our situation?  I put TDH ( transmission,differential,hydralic) oil in my Muncie and my Winters quick change at speedweek.
   My first pass the car started slowing at the 4 mile. By the time I got to the return road the car would not even roll. Turns out 1st gear became one with the mainshaft in the trans.
  I did some percision machine work with a Makita grinder ( ground off all the teeth on first gear) and kept running.  I put 85w 90 in the rear before I made any more passes as I did not think I had any extra gears to grind on in the rear and did not want to take any chances. That said I did not see any problems with the rear and would like to try some lighter oil again.
  The trans shop I bought my new Muncie parts from recomended 50w in the trans. This is standard OP in Roadrangers ( big truck transmissions) but as I said above I am a little gun shy at this point.  Thanks Vince

Beaver recomended I run their standard gear oil, which of course doesn't give you any info on the label........go figure.  I think we could probably get away with something lighter than 90 weight as long as it is a "climing gear lube" that is available from Speedway Motors and most roundy round suppliers.  I had some circle track friends try Red Line synthetic in their Q.C. and it did not like it, but they are under a lot more load and for a much longer time.......You might call Joe Timey at Delaware Chassis and see what he thinks, he is a dealer for Winters.............Bob

Vince,
I would not try lighter gear lube in the rear. I use 75W/90 Amsoil in all of my rears. I installed sensors in a couple of 240 mph cars and only saw a small temp increase. The most important thing is to NOT overfill the rear.
