Title: Petcock rebuild
Post by: cvt on October 10, 2007, 09:10:37 PM
Is there anything I should lookout for when rebuilding the petcock on my 82 Vision?

there is a small, nearly invisable screen behind the square metal plate, on the plastic diaphram plate. some i've rebuilt had them & some didn't (lost?)

watch out for corroded aluminum where the plastic tube fits in.  if it's really bad, missing a lot of metal, build it back up with JB weld, & use a dremil to shape it back out.

other than that it's an easy rebuild.

I use small metal brushes with my dremel to clean the petcock metal parts, to go in the nooks and cranies, to make sure all is sparklin' clean...

Just finished rebuilding the petcock, reinstalled everything and sure enoughf it's still leaking.
It's leaking more then before right from the bottom piece that is pushed in.(the part that the fuel line sits on)
Is there a "o" ring gasket that has to go there or does the bottom piece have to be really pushed in hard?

i don't have an 82 to look at, but if i remember right:
the screw is a drain, it has a plastic washer.
the fitting is just a press fit, i don't remember there being an o-ring.
a little fuel proof sealer should fix you up.

My 82 petcock is leaking from the same place.  I just swapped out my 83 tank last week and put the 82 on and filled it up.  Noticed a gas smell and then the drips.  Looks like only a couple drips a day but enough to smell up the garage.  I tightened things up but it still drips.
I'll dig into it later when I get done with work and mid terms.

I will give the fuel proof sealer a shot this weekend

Press it in hard.  Word on GSResources is, best to replace the petcock, rebuilds are often unsuccessful...

Of course, you would need the assembly to be available, and these days it's not always a given...

Methinks we need to call to see for sure:

http://www.hondayamahasuperstore.com/pages/parts/viewbybrand/2/Yamaha.aspx

They report that the 1983 petcock assembly is in stock, and you should call about the 1982 petcock.  The tanks are, of course, unobtainium, but many of the ancillary parts are still available.

Last time I know of an 83 petcock being ordered, it was on backorder with no known date of delivery (if any).  Maybe they have one in stock, but I highly doubt it - especially if they started doing business after 1983.

If you doubt it, follow the link, plug in Yamaha, motorcycles, 1983, XZ550RK - Fuel Tank.

You'll find that they have a price posted for it.  In the 1982 schematic and list, it has no price but "call us" in it's place.

I think I got the last NOS 83 petcock 2 years ago.  ;D  SmokinJoe has it now.  ;D

They can't laugh at you as effectively through email!
