Specifications

Problem:
The new pulley does not it into the slot for the old idler pulley.
The engine support bracket is now positioned at a slant to the
engine and can no longer be screwed onto it.
Cause:
According to “Opel TIS”, the old, mechanical tensioning pulley
from CT 1014 K1 can no longer be used. You must convert to the
new type (as factory-itted as of engine number 328704).
Solution:
To mount the new pulley, an enclosed stay bolt has to be
screwed in to the right of the injection pump pulley. This now
serves as the catch for the modiied pulley spring. The old
engine support bracket must also be replaced with the likewise
enclosed new type. This is necessary because with the new
pulley there is no longer any base plate, which also previously
served as a spacer plate for the engine support bracket.
Tightening torque: 49 Nm.
