Dear Leo,
honestly I am not too happy about the desription of the French. Important things like to desribe the mechancal seal and how to replace are missing. Merde.
You can copy the pics and the pics are numbered. The try of my translation is referred to the pics. I think a smart mechanic will handle the repair.
Maybe the wording sounds a bit strage, so it´s the translation from French to German and back to English.

PIC3
Fasten the pump in a vice or similar with material to protect the surface so that you can press the pump shaft from beltside in direction to impeller.

For disassemble / reassemble heating up the belt wheel may help.

PIC4
At this moment you must have 2 pieces in your hands:
the pulley with the pump body in aluminum with inside the ball bearings and the axle attached to the impeller

PIC5/6
Secure the pump body in a vise without tightening and press the shaft out in direction of impeller

PIC7
Remove the circlip and the metal washer

PIC8/9
Turn the pump body in a vice always without tightening it and with a 16mm diameter shaft, press to remove the 2 bearings and the washer out

PIC10
Here the desription of the machanical seal is missing

Check if the shaft is not damaged

Clean all parts carefully (to clean the fan part with demineralised water and the rest with motor cleaning products)

PIC11/12
With a tube or shaft of outside diameter of the bearing, press the 1st bearing into the aluminum pump body (warming up the aluminium may help)

PIC13
Locate the washer between the 2 bearings

PIC14
Repeat the same with the 2nd bearing

PIC15/16/17
Add the steel washer and the circlips

PIC18/19
position the rubber seal and the mechanical seal

PIC20
Press the impeller with its shaft in the pump body

PIC21
tighten the belt wheel

PIC22
press only on the shaft of the impeller (check to leave ½ mm between the impeller and the pump body)

Good luck
HP

Dear HP, thank you very much for the translation and photographs. I took the whole lot to the company that supply the bearings and seals and they said that it would be no problem to do the job. I can only hope that it turns out well. I wonder, if you are familiar with or know anything about the decompressor on the engine. Is it only involved with the kickstart, or also the electric start.? Is it something that requires attention/maintenance, or if I'm not using the kickstart do you just ignore it. But, I do have periods when the engine doesn't want to start on the electric starter motor. And, I was reading one of the other posts where someone was having starting problems and they were enquiring about the decompressor working or not working. But, I couldn't find any follow-up answers to this post. It's not an emergency but if you have a moment (or anyone else) could you please give me some background information on the decompressor. Thank you Leo

Dear Leo,

since 1989 I´m doing with the Saturnos and other Gileras. Honestly I just once tried the kickstart in the early beginning but I think that from engineering point of view the kickstart design is a disaster. So I dismanteled all kickstart stuff out of my engines. A modern engine design needs no kickstart. I know that a lot of guys loving to trample around the kickstart, because it´s cool and devides boys from men. Let them believe in.
So only for kickstart purpose you need the decompression lever. If you need some extra information about to adjust the cable, ask me, it´s easy.
The starter motor is strong enough to start the engine even when slightly tuned. Some problems occurred with corroded connections preventing sufficient revs of the starter. Especially the bigger sized electric cables Plus and Minus from battery to magnetic switch and back to starter motor needs good contact. Clean carefully with sand paper or file even all the Minus connections to frame. Use new screws or nuts to connect. Next to the ignition coil is a frame connection with lots of (black) cables which you should check too. Any informations you need, please ask.
Regards
