[Solved] Petcocks

I'm looking for help from the brotherhood. Could someone please pass along the secret incantations needed to get the &%$#@&% petcocks reassembled on my R75/7? I concluded Snowbum's method is the correct approach, but have no luck in getting the threads to engage.

Do you have a bench vise? That helps as a second set of hands, so to speak. 

There might be a video on Boxer 2 Valve that covers this. 

You are not the first one to cuss these.

After cost of rebuild parts/time/effort, a lot of folks just buy new ones.

John -

Are you talking about the threaded nut attaching the petcock to the tank, or the threaded cap attaching the plastic barb ?

The threaded nut to attach the petcock to the tank includes 1 LH thread and 1 RH thread. If you'll simply flip the nut over and engage in the reverse direction, that may solve your issue. 

Hope this helps.

To clarify, I am talking about the valve itself, not the tank mounting nut.

Yes, I've been trying on a vise, but still not having a good time with it.

Yep, not fun. Try to figure out where the threads start by pushing the two pieces together and rotating them counterclockwise. When the threads are ready to engage you'll feel/hear a click. By then your fingers will be screaming, so use a marker to draw a line across both parts. Then go have a cup of coffee or check your email for a bit and let your fingers recover. Try it again, this time aligning the lines you made in such a way that when you rotate the parts clockwise the lines move into alignment. That should get the thread started, and after a turn you don't have to push the two  parts together any longer.

 

Good luck, and may the Force be with you!

Update: done.

I suppose just stepping back makes the difference. I tried again yesterday and after one false start where it barely engaged, then popped off, it went right on at the second attempt. Whew!

Next time--there probably won't be one!
