Power is below normal. Repeat the preceding step, but operate engine for 30 seconds. Engine speed above 1950 rpm. Transmission is slipping or fuel injection pump is out of adjustment. PROBABLE CAUSE CORRECTIVE ACTION (1) Investigate transmission clutches, brakes, and vehicle suspension for being too tight. Repair as required. Refer to pertinent vehicle technical manual. a. If stall speed is normal (1800-1950 rpm), low performance is vehicle related, or vehicle may be operating under severe conditions. (2) Check vehicle performance on hard road: if performance is satisfactory, limit vehicle operation under severe conditions to short periods of operation. Possible engine damage may be prevented. (1) Investigate for transmission slippage. Refer to vehicle technical manual. b. If stall speed is above normal (more than 1950 rpm), low performance is transmission related and engine is over-powered. (2) Replace fuel injection pump (WP 0115). END OF WORK PACKAGE WP 0041 00-2
