Hello, while I wait for the pistons I bought in Japan to arrive I keep disarming and cleaning parts
But I stopped when trying to remove the rotor,the central screw is very hard and I think then you need an extractor, there is some trick to remove this ?

[Bryanj]

Easiest way to remove rotor bolt is an impact wrench either air or electric, yes there is a special tool to remove rotor it looks like a bolt that screws into rotor after holding bolt is out. DO NOT USE A 3 LEGGED PULLER

I bought an M16 1.5 bolt from this seller. Worked perfectly.

Thank you very much for the tip !!!
You saved me a lot of time
The screw was very hard

Sorry to abuse your wisdom, but does anyone know if there is an oil pump seal kit for sale?

[Bryanj]

The 3 O rings to crankcase should come in a complete gasket kit and the cover O ring Honda never sold as a spare but if you get a 46x2 O ring which is a Goldwing part it works

[murdock]

Unfortunately my seals kit does not have them, the pump I do not plan to open it, that will be the 46, only would be the ducts and the one that seals the body to the housing, then try to measure it, but measures more than 50 mm x 3mm small I think 14

[Bryanj]

They do not come in the SEAL  kit they come in the GASKET kit

[murdock]

My kit is not complete, I have taken measurements, 14x 3 mm and 53 x 3 mm I think it would work well, the 46 mm will be the inside, but I will not open the pump.
I will buy them loose for a few cents.

I have opened the engine, everything seems fine, but I have found some wear or rubbing on the central selector fork, I don't know what gear it engages, the gearing looks fine, tomorrow I will check it in a better light.
Those are the numbers I was supposed to find right?

The gear

It's better to be clever than to buy more tools,
I don't know if I should worry about the shift fork, I'd just give it a little sanding and that's it, but you're the experts.
The bearings look good too. I have plastigauge ..... I don't know what to do , I change the chains and rubbers ,Seals and seal again ?

[murdock]

Chain friction was negligible

[Bryanj]

I would replace the fork, with that wear it is probably bent the 550 primary chain does not hit as much as the 500 presumably the casting is different, still worth replacing chain and dampers
