So I have a tatty 87 Toyota pickup, with a rotten 22RE, but rest of truck is not so bad, little rust etc. I am seriously looking into EV conversion. Can someone point me at tech on whether to keep the 5speed transmission, or ditch it and mount an EV motor directly to the transfer case? The transmission is a lot of weight, and general wisdom is you wind up leaving it in 2nd or 3rd gear all the time anyway. Why not mount the electric motor directly to the xfer case, and lose the transmission weight, clutch, MC, slave, bellhousing, gearshift in the already crowded cab and so on?
I have a spare xfer case already (I have several of these rigs in various states of evolution). So fabricating a bracket to mount a motor to the xfer case, fabricate the motor mounts to the frame and design/machine a coupler does not seem that daunting a task.
I dont want a racecar, and I certainly dont want a 87 Toy pickup that can achieve high speeds (65MPH would be nice top end). But removal of the 22RE, gas tank, and trans should leave ample room under the hood for lotsa batteries.
Based on this page the truck should have a W56 trans, with ratios:
First - 3.954
Second - 2.141
Third - 1.384
Fourth - 1.000
Fifth - 0.850
Reverse - 4.091
The Xfer case should be 1:1 in high range and 2.7:1 in low range. I believe the R&Ps will be 4.88 front and rear.
Thoughts?
