13 Inch 36 Volt Dual Field Series Wound 8000lb Drexel Forklift Motor and Original 2-Speed Automatic Powerglide Transmission with 1.82 low gear Race Modified
What I did to my Powerglide I cut the torque converter in half with a band saw and had a machine shop torch out the center part that turns the tranny pump. Cut off the tranny input shaft to meet up with the electric motor shaft. Designed piece of metal to connect motor to tranny input shaft and tranny pump. Had machine shop weld it up. Cut stator support off of front pump with band saw. Drilled holes in front pump for more lubrication for thrust washer. Took out 2 of the five reverse frictions and the wave steel and replaced with 3 steels. High drum was left all original and never disassembled. Will modify next time I tear down the tranny. (This has now been modified. On a 1/8 mile run, the original cast clutch hub exploded in many pieces. I replaced it with a lightened steel clutch hub and installed grooved racing frictions. Also removed the wave steels and replaced with regular steels and re-adjusted clearance to race specs.) Installed Transgo kit to make Full Manual and drilled holes in metal spacer between valve body half's. Did "not" install higher pressure spring. I used all the original seals and rings and did not want the higher pressure at this time. Removed rear pump and governor and installed roller bearing Governor support. Installed cast aluminum deep pan and roller bearing tail housing. Removed cooler bypass valve and downshift timing valve from front pump. Plugged up cooler lines. (Not sure of this procedure, but I thought I read it somewhere) I have been told that a small hose should be connected between in and out cooler lines when not using a cooler. Removed filter and running without one for less restriction. Further modifications depends on how this one lasts on the track. This was the first time I ever attempted to build or modify an automatic transmission. Anyone could do this if they read and study the books on the Powerglide.
The 13" Dual Field Series Wound Forklift Motor (From an 8000 pound Drexel Forklift) found in a machine shop while they were doing some work on a conversion project for me. Here are the numbers on my motor: 5BT1374A15 on the tag, Drexel PN 8855 on the tag and 36B 550 639AA stamped on the case. I am assuming that the one stamped on the case means 36 volts, class B insulation, 5500 rpm and 639 amps.
