912UL Issues

[Av8r3400]

I did the whole reassemble in reverse order thing today. I installed the new "spring discs" into the assembly replacing the partially collapsed old ones. There really wasn't anything to photograph with that, so...

I did take a couple of shots of the press tool used to disassemble the gear box shaft assembly.

1st photo: This tool is intended for the "B" Rotax 2-stroke box. This is the same tool they use at LEAF, on the 912/914 boxes too. They told me they modified it to fit the larger box. I didn't want to modify the tool (it isn't mine) so I made some shims to help it fit the larger gear better.

2nd photo: Here is what the tool looks like by itself on the gear.

3rd photo: Here is with the shims to spread out the force on the gear a little more.

You put the assembly in the press, supporting the prop flange and then press on this bridge until the retainer clips release. Easy peasy.
