Just for mentioning the gears 20 and 17 have different contact profile (little wider) than the originals.
When I installed the 20-21 combo on the cover and pressed it all the way in so the clip could fit the gears got stuck together. If I removed the clip and back up the gear with the bearing everything was ok. Check every part old vs new to see for any differences because it could be that I was the lucky one who got parts with differences and cursed all day. ( I believe that parts from Rieju are all different even the stator cover. The bendix cover that I bought is definitely better tho with the bearing and the sleeve inside.)
Answer to 2. You can apply some small quantity of Permatex steel weld on the grooves of the shaft and then press the pinion in and after that puss the bearing and finally put some thread locking compound and tighten the screw.
This way you can secure the pinion to the saft for not spinning as it happens to many.(I have fixed mine and four other safts of customers until now.)
Answer to 3. You can use a vice and the sockets of a 1/2 ratchet to puss the bearings to the gears and the pinion to the saft.
Also for fitting the 20-21 combo to the cover after heating the cover you can use a circlip opening tool like the one you need for the clip that holds them in place to grab them from the inside and puss them in.
Hope I helped you a bit.

Spiro, this helps a lot! I am getting the top of the bendix shaft and pinion/gear welded this afternoon and hope to install everything tonight. Thanks again! Iakovos Bozonelos
