transmission over sr/s
« on: June 03, 2024, 12:20:41 AM »

Good morning,
as I said some time ago, I change all the elements of the transmission: pinion, crown, belt.
I succeeded but not without difficulty... :evil:
the crown, the belt, this can be done with your eyes closed, be careful the crown screws are also mounted with loctite.
on the other hand the pinion, it is mega stuck, its retaining screw also, at the beginning, I wanted to try to loosen it, but it is impossible, without blocking the pinion which turns, it would even take two people.
I marked the imprint of the screw so much that I had no other choice than to drill the screw head to remove its retaining washer. :evil:
to extract this screw, it will be necessary to drill, place a screw extractor, and heat with a blowtorch (the release temperature of the loctite is a little over 100°C, and so much the better).
for the pulley, I had an extractor which worked well, the same, you have to heat it well, it works quite well.
just be careful not to heat it too much, I used a laser thermometer to help me.
it was armored with loctite on all floors, there was no risk of it moving.
I still noticed that the old pulley does not have the same reference as the new one, I was not able to mount my extractor in the screws of the old pulley, whereas in the new one, it was good , visually, they seem identical...
the ordered reference 30-08210 and the received reference 30-08403.
well I imagine that it's not a coincidence that zero changed the reference, and that I find myself with a piece of shit that destroys all my belts fitted and correctly, I hope that's it :cry:
I'll give you some images of the site, I struggled, but like every time, with the right tools and a lot of thought, we get there (well I probably drank 15 coffees this morning, and smoked 30 cigarettes)
everything was reassembled with red loctite, I tightened the holding screw as hard as I could with my DIY filter wrench, it held pretty well, with an old piece of belt...

I have no idea why they felt to go so overboard with the loctite, it's not like it should experience much if any lateral load. The unofficial manual does recommend a blowtorch. I haven't had the pleasure of trying to remove mine yet but I'm not looking forward to it.

Hopefully, I will never buy your bike...

Looks like "Pfusch".

Some notes...
Don't use Hammer und much Heat on the motor. Motor-Magnets (and Bearings) don't like both of them.
A small gas soldering iron, for only heating the screw will be fine.
Use  the best tools you can get. With HAZED tool, the screw is no problem.

(If Zero needs so much Loctite, the whole design of this is bull***)

best regards

The motorcycle has been repaired according to the rules of the art.
If you were to buy my motorcycle, you would not have a problem, since everything is done according to the rules, and the labor time does not count.
Do you think the dealership repairs your motorcycle better than the local mechanic??? lol
best looks

ps: I'm not pfusch...

assembly completed this morning, the tension is perfect, the alignment is perfect. (65Hz)
an incredible thing (for me) that I have just discovered, since the assembly of the entire transmission kinematics, that is to say pinion, crown, belt, I have a right left oscillation of the belt on the pinion and the crown , without ever touching the edges, which I certainly didn't have before, seeing as I had very marked wear evenly on the crown and especially the pinion...
the fact that this belt oscillates will cause uniform wear on the elements transversely.
well, as I like to say, I hope my problem is solved, 1 more  ;)

If alcohol could solve all problems, I would probably be drunk all day long  ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D

Thanks for the tour, I will add these pictures to my maintenance files.
I hope I never need them!

unfortunately, at a certain mileage, everything will certainly have to be changed.
for my part at 44,000 kms, I find it distressing.

My Zero mech changed me the motor sprocket at 71'000 km, but due to wear (from rusting) to its inner teeth. Seeing what that meant for you I am glad I didn't try myself. Thank you for documenting what you have done.
