Technical / 6 spring clutch spanner
« Last post by Lilyloodles on Yesterday at 10:35:41 AM »
Can any of you very knowledgeable people point me in the direction of a suitable box spanner/socket for tightening the clutch mainshaft nut? Also a suitable box spanner for gearbox inner casing nuts? I've come to the conclusion that my mainshaft is pretty torn up around the key slot so I need to change the shaft. I have another one that is in an old gearbox but I can't get the inner casing off. Is this the easiest thing to do as I've never broken a gearbox down past the outer casing before and it looks a little daunting to say the least.

Was working on a friends outboard motor today, and it reminded me of this thread.
Although the thing is quite old (1986) it looks brand new with all the original paint intact. He used it just once before noticing fuel pouring out of fuel tap.
It is a truly terrible design as the user in this forum post confirmed, and Yamaha who made it quickly changed design on next model.
The problem is the tap is short 90 degree cranked affair with a foot long operating lever....and of course no direct replacement available >:( to drill case and fit in line tap and filter :(
Told him he should have bought a British Seagull :D

I'm with G&T, if it doesn't leak then just use a rust remover to clean it. I personally like to solder the leaks, if there are any, as it works as well as brazing or welding.

if the inside is simply rusty, then various acids alkaline's will remove/ neutralize the rust - then fit a fuel filter.

If its flaky - above + nuts bolts bits of chain etc rattled around inside will help - then fit a fuel filter.

If it leaks - weld it, its not hard and often you can minimize any paint damage - i had a row of holes behind the knee grips on my C11, after brazing, new knee grips nicely covered the braze - i then ruined the job with a repaint cock-up  >:(

If you simply want to sell it - then use some epoxy/polyester slop inside it and get shot fast, BUT expect any savvy buyer to knock you down on price because of the sealer.

You may get from the above i have absolutely no faith whatsoever in the chemical crap used to seal tanks !!!!
I've just spent a week cutting the bottom out of an ali tank, to remove the epoxy - after the idiot tried to use some sealer in it, converting a 5 minute (literally) FOC welding job  into an epic which hes not happy to have to pay for !!!!

I've tried various sealing products + all my biking mates, over the years and none of them give a permanent/long term solution, based on experiance !

Had no problems with PQR 15. Easy to use , thin enough to slosh about, then it thickens up but leave it a week to harden and cure.

I can only confirm one thing - give it TIME. I did a BMW tank and left the goop at least twice as long as it said in the instructions to 'go off' [in fact as it was winter it was left almost a month before I added fuel]. Was still fine when I sold the bike.

It's just a mind-set to get into.
Some bikes (often with Pilgrim-type pumps) and two-smokes had oil taps as standard, and it's not a big problem to arrange some little aide-memoir to jog your memory on the first start of the day.

Yes, I was going to add that Ian, I used three boxes of self tappers.......I didn't use a cement mixer, just had a damn good workout,  and used the cleaning fluid that came with kit.
