Petrol Valve

#1

Post by bavarian_knuckle » Sun Dec 23, 2018 4:10 pm

Hi guys,

since I've pulled my gas tanks on my Knuck, here's another question. The gas valve tends to leak a bit ... do you guys have an idea how to fix this? Is there a tool available to match the tip of the rod against the gas valve nipple?

thanks
KLaus

Klaus,

I have a tool to Align the shut off rod / tank.

I am in Bayern, near Kitzingen.

If you need the tool to align the tank/ shutoff rod .. let me know and I can let you borrow it long enough to fix your tank.

I bought the tool when I was redoing my WLA, and it has just been in the cabinet waiting for another job.

Clean the parts.
If that fails replace the nut and seat
If that fails replace the rod

We make a leak proof gas valve that has a PEEK tip and Stainless Steel seat that will solve your leaking gas valve, as it has done for many users in the past.

I'm using several of Carl's shut off rod set ups, with great results.

Carl's product is well made and I have friends who have them with no problems, I recommend it.

That being said I have polished in the seat on the valve by chucking it in a lathe and using a plastic "stick" with the angle matching the rod and lapping compound to polish the seat. Polish the seat like lapping a valve, I used a delrin stick but I imagine wood or aluminum would allow the compound to "charge " the stick. Polish the rod, clean the seat, screw them together and blow in the end. Cheap fix.

Klaus,

When I was overhauling my WLA, I had a problem with the valve on mine as well.

I found out that one of the problems was the aftermarket washers were too thick spacing the valve seat further away from the rod. And that I needed to purchase the tool to align it all.

1st done the alignment and spacing adjustments then:

Got NOS washers from JWBoon in Holland and that almost fixed the problem.

I took a similar approach as Andy's to lapping the valve and rod's seat by using a somewhat abrasive tooth paste and cigarette ashes to make a paste and lapped it in with a electric drill.

Worked, and is still working.

Simple and it worked.
