Re: (ET) Elec-trak Digest, Vol 7, Issue 179- E20 Gear box leak.
E20 Gearbox leak - Chris Zach
Chris
Remove belt from pulleys, remove gear handle knob, remove wheels, remove 4
bolts , drop tranny, remove pulley, drain gear case. On the E12 the tranny
was a Tecumseh, they have all of the parts. I replaced a pinion seal
without grave difficulty. Suggest calling Tecumseh with tranny model
number.

0 EV's but still fascinated.
