Not Grinding Gears

Hi Guys,

The advice you guys gave me regarding my gear grinding problem was great. I got it all back together yesterday afternoon and let it sit over night so the gasket material would harden. No leaks today, so I took it for a little spin. And guess what? Those gears went together like syncromesh! Just as slick as could be. I had drained all the oil out of the transmission and the rear end. The rear end was just dirty old stuff, but fairly thin for a rear end. The transmission was just as bad and it did show some water as the oil at the bottom was kind of milky. I cleaned it up and refilled with 85-140 and Lucas. I put 5 quarts of 85-140 and a quart of Lucas in the transmission case. In the rear end I put 2 pints of 85-140 and a pint of Lucas on each side.

It's running good and I hope to be in the Paquette Historical Tractor Museum parade in The Villages, FL this Friday.

Thanks again for the tips!
 
What is the Lucas oil you added to the 85-140. I think I"ve seen a Lucas oil to be added to engine oil, but is there another Lucas oil for a transmission additive?
 
Lucas HD Oil Stabilizer. I got it at Walmart. I don't think it's made especially for transmissions. They do have an additive for automatic trannys, but this is for gears and engines. It's pretty thick, sort of like STP. It sure quieted down my "A" transmission.
 
Pretty work! What I'd suggest is to drive it enough to make sure the oil and the additive are mixked up good and open up the check level plug to draw it down to that level. One of the more common causes of leaks is overfilling, and it will leak out around the seals where the differential shafts pass out through the tranny case. Those seals are made to hold back what sticks to the shaft, not a puddle of oil.

That said, sounds like she's quieted down real good.

Enjoy, and happy motoring!
