Belt Adjustment Procedures Information

Part A - Belt Adjustment Procedures

For engines up to model 1986 with tensioning roller, refer to Workshop Manual 944, Vo. 1, Page 15-3 or Technical Bulletin Group 1 No. 8601 dated February 14, 1986 for belt adjusting procedure and specifications. Always use special tool 9201 when adjusting the toothed belts.

The procedure for engines from Model 1987 with mechanical tensioner are found in Technical Bulletin Group 1, No. 8620 dated October 13, 1986 and in the 944S servicing, assembling and adjusting guide WKD 493 521.




Adjustment procedures are as follows:

1. Engine must be cold.

2. Cylinder No. 1 set to TDC.

3. Loosen nut (2) and bolt (3).

4. Calibrated spring will press tensioning roller against belt.

5. Tighten nut (2) and bolt (3) to 14 ft. lb. (20 N-m).

Do not change the factory set tension of the mechanical tensioner.

Never turn the engine with the tensioner loose. The belt may jump the roller.

When setting engine cylinder No. 1 to TDC, do not reverse direction. If necessary, complete additional revolutions and pull up to T.D.C. No. 1. After adjustment, checking of the belt tension is no longer necessary.

Balance shaft belt adjustment and assembly procedures can be found in the 944 Workshop Manual Vol. I Pages 13.3 to 13.11
