Re: 12 bolt gear oil
I have 5 Gallons of the old Heavy Shockproof (Red) if anybody would want it ... Never opened ... Back when we were going through 6.00 gears every 50 runs, I tried this . It did help .... But a 9 in. was the cure ....

Re: 12 bolt gear oil
I wonder if anybody has ever tested oil level in a 12 bolt. I think that your better to have a slight over fill then an underfill condition. If there is not enough oil then the gear runs dry and you create friction. I can't imagine there is much ET between running 1 and 2 qts. That's just me

Re: 12 bolt gear oil
The gears will not run dry with 1 qt. My only concern would be the axle bearings. Sounds like 1 qt is what many use.

Re: 12 bolt gear oil
I have 2 qts of Richmond GL-5 in my 12 bolt, and put 220-240 runs a season on my pro gears. I think these gears have been in for at least 4 seasons.

I've run 1 qt. 85-90 synthetic, quite a bit ,and never hurt anything. The cover design on a 12 bolt, directs oil right to the side bearings anyway. That being said, it's been determined by several racers, that a lot of the oil goes up into the axle tubes anyway, and that 2 qts. won't hurt you much. A personal observation: If you are going to try some kind of super light concoction for a record run or something, make sure the gears are well broken in with the regular stuff first. :-(

Re: 12 bolt gear oil
2qts should be just right. As far as axle bearings go on axles like a Ford 9" the seal is in the tube behind the bearing from the factory. I can't remember how it is with c clip eliminators. I never saw the advantage of the heavy shockproof in a rear. I prefer flow over it sticking to non wear parts. It's impressive if you disassemble as gar as how it coats everything.
As far as support goes I don't think anyone holds a candle to Lucas for support and their products are great. I like Lucas synthetic gear lube. |
