CAMSHAFT & CRANKSHAFT LOCKING TOOL SET

Applications

For use on Twin Cam enginees where both camshafts have to be locked in place whilst servicing the camshaft and replacement of the chain or belt.

Note: The straight 6 cylinder engine is aluminium and the straight 4 is steel. Occasionally corrosion on the steel casing can make the Crankshaft Locking Pin tight.

The Cranshaft Locking Pin is ﬁtted after the crankshaft has been turned to TDC (Top Dead Centre) on No.1 cylinder (A)

Note.Check for corrosion on the steel engine block, normally found on the straight 4 cylinder engine as this may cause the Pin to be a tight ﬁt.

The Twin-Cam Locking Plates are positioned to align the cam shafts at the correct timing position. The fork on each plate locates on the square form of each camshaft. The two plates are fastened together by means of a latch strap. (B)

The application list for this product has been compiled cross referencing the OEM Tool Code with the Component Code.

In most cases the tools are speciﬁc to this type of engine and are necessary for Cam belt or chain maintenance.

If the engine has been identiﬁed as an interference engine valve to piston damage will occur if the engine is run with a broken Cam belt.

A compression check of all cylinders should be performed before removing the cylinder head.

Always consult a suitable work shop manual before attempting to change the Cam belt or Chain.

The use of these engine timing tools is purely down to the user’s discretion and Tool Connection cannot be held responsible for any damage caused what so ever.

ALWAYS USE A REPUTABLE WORKSHOP MANUAL
