Subject: CRANKSHAFT PULLEY BOLT BREAKAGE L17 AND L18 (1.6L AND 1.4L) L4 ENGINE

1981-84 1000

Effective with 1985 production, the 1000 1.6L L4 engine will use a new "one-piece" timing belt sprocket and spacer. The new "one-piece" sprocket and spacer will be available in a service kit, P/N 14090950, from WDDGM. This kit should also be used to service 1981 thru 1984 models. The kit will contain a sprocket and spacer, P/N 14076378, bolt, P/N 14076332, and a label, P/N 14076356.

The replacement procedures are covered in the 1985 1000 Shop Manual, Section 6A1.

CAUTION: When the front cover is installed, aligning tool J-26434 must be used to properly center the cover seal on the crankshaft. Failure to use this tool may result in a subsequent oil leak.

To ensure that the threads of the crankshaft pulley bolt hole are not damaged while drilling a broken bolt, the use of a drill guide, J-34984-2 is recommended. A dowel pin washer, J-34984-3 is required to ensure that the dowel pins are not damaged during installation of the sprocket and spacer.

Failure to apply 90 to 100 foot pounds (122 to 135 N-m.) of torque to the crankshaft pulley bolt may cause a failure of bolt and/or pulley. This will require holding the crankshaft to prevent its rotation while tightening the bolt.
