1 x SE841 XK120/140 Tacho Converter. Our own unique design of adaptor for later Straight port heads ( with Electronic Tachometer Drive)  fitted into the earlier XK120 & XK140  vehicles.These earlier Jaguars feature as standard a unique  Anticlockwise (counterclockwise) mechanical sweep  Rev. Counter i.e. XK120 & XK140 Early Smiths  X49035/5 or Later XK140 Smiths Type  51-117-102-04 (shown)  that would have been driven by a mechanical drive off the EXHAUST camshaft.

This is a mechanical angle drive adaptor, specially made to bolting to the 3-hole later threaded hole  fitment on the straight port heads which is on the INLET camshaft side. It converts the motion from clockwise on the Inlet Camshaft to anti-clockwise to drive the XK140 Tachometer gauge , which normally runs off the Exhaust Camshaft. The drive adaptor comes  with a unique 20 ½" drive cable to reach through to the gauge with ease. The solution if you have a later head on your car but wish to retain the standard dashboard gauges. ( THe Electronic gauges are rare and difficult to rebuild now).
