Hello everyone,
next rare and old find:
HAZET 763CT-20 torque limiter for spark plugs from the early 1980s.
A 20 Nm torque limiter for 1/2" spark plug sockets only engages when tightening the spark plugs.
(90 mm long, 28 mm diameter, with a 200 mm fixed torsion bar).
Under the circlip, there is only a round cap that secures the torsion bar in a recess – below that is a nut for the mechanism.
From 1985 to 1988, a similar torque limiter tool, the 763CT, was advertised, also for 10, 20 and 30 Nm, but all with 3/8" drive at the bottom and top, without a torsion bar.




regards,
