[Healeys] Leaky Banjo Fittings at Carbs

[Hank Leach]

I dont think its the wrench, as both fit. It is more about the type of
fiber washer and the proper placement of it. If you "wiggle" the
fitting as you insert it by hand it will help to not strip out the
casting (which is the scrafical item). If it does not start in
smoothly, STOP and redo it again by hand. Carb bodies are expensive.
Yes, WD-40 or even a bit of red grease will help the mating of the two
threaded parts. "Genuine" SU parts are the best to use if you can find
them. Hank

 Sure, but 13/16" fits well.

  Bob, 
 I think that SU fittings are Whitworth size wrench sizes..not
13/16". And you can strip out the threads in the cast fuel bowl lids.

 Are the washers brown or black? I believe the brown ones are the
 original type and the black ones are being proffered by some
suppliers
 and may be slightly undersized. I usually, if I think of it, soak
them
 in WD-40 for an hour or so before installing, and re-torque them
after a
 day or so because they do take a set. I torque them 'elbow-tight*'
with
 a 13/16" half-inch socket and wrench (fits the bolt head well). It
would
 be difficult, but not impossible to strip the threads on a banjo
fitting
 as they're coarse (you'd likely strip the carb or pump threads, not
the
 bolt).

 * Torque settings : finger-tight, wrist-tight, elbow-tight,
 shoulder-tight and all-you-got tight.
