New Tachometers and Speedometers
572 Series
Now Available:
A new range of speedometers and tachometers to replace the out-of-production
Smiths and Veglia gauges for popular
Triumph applications. These units differ only slightly in appearance
from the originals, but have the advantage of modern internal design and
good availability, with no exchange unit or core charge required.
We also offer a rebuild service for original
Smith's speedos and tachs
At present, these new tachs and speedos are only available in the ratios listed, but no doubt
others will be added in the future. In the meantime, with use of the correct
drive gearbox, these can be used on virtually all Triumph models using
the "large" (3.14" O.D.) gauges, except for certain ones which drive
instruments directly off the engine or transmission
since they have a different ratio.
It should be noted that these
instruments have no manufacturer's name on the face, which is similar to
original design as used on late model Smiths (black face with white numerals
and needle) and that standard cables fit on as original with no adaptors
required. They do require a different bulbholder assembly than original, BCS
# 572-10, which must be lubed with rubber lubricant and installed very
carefully due to tight fit to keep water out.
Bulb for this holder is BCS #392-504.
The stud mounted instruments will bolt onto stock instrument "brackets" as original, using the original nuts (21-0778). The instruments without studs are best for rubber cup mounting as used on most Triumph models 1971 and later.
When ordering, if possible quote numbers of the old instrument or speedo drive unit; if the old speedometer is not a 1000 rpm per mile unit, a replacement rear drive of the correct ratio may be required.
For comparison purposes, sizes are as follows:
BCS Replacement instruments: O.D. 3.14"; Height 2.15"
Veglia Instruments: O.D. 3.14"; Height 2.23"
Smiths Instruments: O.D. 3.14"; Height 1.78"
At present, we
do not have replacement instruments suitable for BSA or Norton models, with
the exception of the 572-11/A tachometers which will fit all Commando 850
models, but we will announce additions to this range as available.
