| Subject: | Tri-gear nose wheel O ring size & NGO5 dimensions. |
Hello everyone,
My kit was missing the BS214 O ring and NG05 friction plate. I'm at the
point of giving up trying to get them from Europa and making them. I
need to know the thickness of the nylon friction plate, the size of the
hole and the O ring thickness.
My guess is 1/8" thickness of the material with a 1 1/8" hole and a 1" ID O
ring , 1/8 thick.
If anyone can help I'd appreciate the information.
Thanks, Paul

Not quite Paul.
NG05 is 3.00 IN OD, 1.0 IN ID, PIN HOLE 1/4 IN Centered between ID , and OD
edges or 0.5 inches from the edge. ABS plastic. I would machine from FRP
G10 of 1/8 inch thick. Easy to do on a drill press. Buy the FRP, 3" Hole
saw has to be 3" ID so I use a 3 1/8 OD instrument hole saw. CLOSE ENOUGH
.
The O-ring depends on your depth cut of the steel spacer defining the O rin
g recess.
Ideal O ring is 1/8 inch thick. 1 inch ID, 1 1/8 OD. SOME are in need of a
3/16 thick Oring with ID of 1" to seal properly due to builder tolerances
in modifying the original non sealed base. This was a cut and file mod .
Some cut the bearings, others the steel to preserve the bushing thickness.
Idea was to prevent grease from running out on the plate. That leaky grea
se decreased friction and was a continuing shimmy issue. Seal the base and
life is good.
Make sure the spindle is square to the yoke.
