Weber / Dellorto Soft-Mount Hardware
Soft mount Plates - Metal plate
with bonded O-ring replaces the old style carrier and separate O-rings. This is a
superior soft-mount system. Two plates required per carb. Plates fit 40-48mm
carburetors.
Ref. 26S0010 $10.00 each
Carburetor mounting cushions and cup
washers - Rubber cushions are shaped like an hour-glass, allowing the carburetors
to be tightened sufficiently to seal against air leaks yet remain flexible. Cup
washers help retain the cushion's shape and keep the cushions from spreading too much.
(Installation note: Compress cushions by @ .100". Do not
overtighten.)
Ref. 36E0470
Carburetor Mounting Cushion $3.00 each
Ref. 36E0471
Cup Washer for carb cushion $1.50 each
Thackery Washers - An
alternative to the rubber cushions, these spring washers are only partially tensioned
during installation (leave a gap of .035" - .050" between coils). The
thackery washer keeps tension on the carburetor yet retains some "spring" to
allow flexibility.
Ref. 75W4040 $1.50 each
Nylon Locking Nuts - Good nyloc
nuts are necessary to hold the cushions or thackery washers at their installed compressed
length without loosening because of engine vibrations. Most installations use
5/16-24 thread studs, and we supply aircraft-quality "AN" full-height nylon
locking nuts.
Ref. AN365-0524 $.50 each
Installation Tip: Use the rubber cushion mounts on the top carb studs (this is where the thackery washers tend to fatigue and break), and use the thackery washers on the bottom carb studs where the inevitable fuel leakage from the carbs will cause the rubber mounts to soften and fail.
