Honda Sky SGX50 Crank Seals

Thanks for that....Yeah that kinda makes sense... in the process of making a tool to fit in the holes of the ring gear, and going to see a bloke tomorrow that used to work on these things....

 

Thats how most scooters are

 

Still having problems getting this starter ring gear off, so have made this tool, I fear though that it may not be strong enough for the job, as it is bound to be tight on those threads,next step I think is to strip the right hand side, to get to the other crank seal, and also be able to hold the crank.....it would have been so much easier, if there had been an hexagon on the end of the crank, for an Allen key.....

 

For anyone else attempting this job, the starter ring gear is NOT threaded, but is on a tapered part of the crank shaft.....we live and learn.....

 

I thought so...

 

O.k, that's the L/H side crank seal replaced.....unfortunately I can't test it, because I now have no spark at the plug, I fear that I may have damaged the stator, by placing a screwdriver in one of the holes in it, to stop the crank from turning....I have since read up on it, and it says "On no account place anything in these holes, as it may protrude too far and damage the stator"....that's when you know, and when you don't.....am now waiting for a flywheel puller to arrive, so that we can have a look.

 

So how did you get the ring gear off in the end? Have a puller but it is not really the right one.

 

OK don't bother, got it off in the end, but a pig of a job. Typical honda.

 

Yes, took me a while to figure it out.....I thought that it was threaded......but it isn't......

 

I bet it wasn't as hard to get off as my atv one....

 

That's a 10 ton hydraulic puller.
And I got the oxy/acetaline on it...
Didn't even move....

 

I made a proper tool for it in the end.
It's a 50mm thread on the flywheel.
It actually flared the end of the crank.
Turned out the keyway sheared off and "welded" itself together.

 

Once I got it off, tried to remove old oil seal with a small oil seal pick. It litterally just feel out, totaly duff.
Anyway now that the new one is in, bike runs fine.
Just wondering about refitting the ring gear. I tried to hit it back in place with a piece of 1 1/4" pipe, and a hammer, but it would just bounce off. So I ended up just reassembling and tighten everything back up again. Seems OK but wonder if this is the correct way to reassemble?

 

You should heat it to do it "by the book" but just tightening it up so it clamps together is fine. It's not like it's a really high spec super fast sports bike.
