Engine: Service and Repair
NOTE: When performing engine removal and installation procedures, check and record the distance between the crankshaft pulley and the frame rail, and the distance between the transmission and frame rail. Models with manual transaxle (MTX), check distance at transaxle case. Models with automatic transaxle (ATX), check distance at the oil pump housing. This check should be done before the engine is removed and after the engine is installed. If necessary, loosen the motor mount-to-engine bolts to shift the engine to obtain proper engine/transaxle to frame rail clearances. Proper clearances are necessary to ensure half-shaft alignment. Crankshaft pulley-to-frame rail clearance should be .62 inch plus or minus .15 inch. Transaxle to frame rail clearance should be .98 inch plus or minus .19 inch.
