car door seal ... read the fine print as looks can be deceiving they come in various heights and width.

I have ordered some that was to small.

it grips the edge pretty good but a dab of glue can't hurt .

I got all the new seals in the gear case and I got it back together. It shifts and operates like it should. I don't have any special tools for leaktesting it, is there any way I can do that DIY? Other than putting it in a bucket of water then taking it out and seeing if there's water inside after a few hours, which I really don't want to do because then I'll have to dry everything again.

If you have the pump for the oil you could adapt that to work with a bike pump. If you don’t have a way to hook up a gauge drop it in water and look for bubbles. It only needs like 10 psi so don’t over do it with a compressor.

I don't have the pump for the oil, so maybe I need to get one.

You always fill from bottom till it comes out the top.----On more than one occasion folks came to the shop with burnt gears / bearings.-----They made the mistake on a simple job.

I made a tool for pressure testing the gearcase. I drilled down the center of a bolt, clamped a piece of hose to it and clamped a pressure fitting to the other end of the hose. I hooked it to the air compressor set at 10 psi, and like I feared the gearcase leaks. It's at the front where the piece that holds the seal and the two halves of the gearcase come together. I took it back apart and put some RTV. It's drying right now, but I think it'll work.
