Well I beat the snot out of this tranny, I went through it about 6 years ago and since then put about 200 runs in the 10.30 - 10.60 range, about another 70 in the 10.70 - 10.90 and 17 in the 9.70
John Deere Hyguard tractor hydraulic oil with a couple quts of mercon to give it some tint.
All launches were made off the brake, I use a 2 step to limit rpm to 4000 - 4400 depending.
All burnouts made in 2nd gear, no neutraling at the end of the run.
direct clutch (also called reverse, but this is high gear and is the biggest failure)
This is the first run of Alto reds and Kolenes, 6 and 6, no slip or heat build up, there were some issues with the holes in the steels not deburred well and would eat into the friction a bit which there was evidence of on a few.
This is a stock Borg warner tan friction and steel plate, 5 and 5. I can read the letters on them still.
Just a very slight amount of heat evident, this is an older style kevlar, I have a newer version I'm going to use
seems to have a little more surface area available, both are flex type. I have seen some available in Alto red and carbon, I know for sure the kevlar may have a bit less holding coefficient but you cant burn the damn thing up,,,,hardly.
I use an older Transking transbrake Vb
setup, toss their intermediate servo cover in the trash and use one thats got a 0ring to seal it along with the paper gasket (paper will push out eventually)
The one I had was an ancient JPT unit, the cover we got for my brothers is a PA billet, toss the piston, weld up the small vent drilled into it and roll.
I use a 3 pinion roller forward planet I got from Dynamic 6 years ago, stock rev planet, the forward drum is a silicon bronzed jellybean hole brazed unit from Dynamic as well.
A good input shaft is a must.
This is a full roller unit, I also used a c5 case which has bigger cooler fittings and a fine thread int. adj screw.
Almost considering updating this thing a bit and sticking behind the big motor now, might put an alum int drum that holds 7 and 7 (sounds good right now lol) and add another disc to the forward, get a 2.20 gearset to help the little tires stand a chance.
These tranny's suck........... :lol: :lol: :lol:
