When we installed the motor last month, we didn't know the exact spacing needed between the motor and transmission. For our low speed test drive we had to add a few washers.
Although it worked for the test, it was not a long term solution. The gap between motor and adaptor plate allowed dust and water to get inside. The 3 washers we used were almost exactly 1/4", so I went ahead and ordered a 8" x 8" x 1/4" aluminum plate to make a spacer plate.
Luckily I had dinner plates 8" in diameter as well, and we can't forget my trusty Subway cup.
Similar to the adaptor plate, I used my jig saw and lots of WD-40 to cut the spacer plate.
By the way, permanent marker lines drawn on aluminum wipe away quite easily after they've been soaked with WD-40. I strongly recommend etching the shape you want with a flat head screwdriver or similar so that your lines don't disappear before the blade reaches them.
I used my adaptor plate as a guide for the motor mounting holes.
And then checked the fit on the motor. Despite using the adaptor as a template, I still had to go back with the drill and jig-saw to increase the hole size.
And the finished product! Quite a step up from a bunch of washers.
And the transmission side... I'm using a lock washer, a regular washer, and threadlock fluid so my bolts won't loosen over time.
Before I can remount the motor in the car, I've got a bit of work to do on the coupler that you'll see in my next post. I'm hoping the next time I mount the motor will be the last!
