7 TORGIUE CONVERTER STALL CHEGK ACAUTION 8. After the engine and transmission reach normal operating temperature, the stalltest can be per- formed. Move the shift selector lever to D. Fully apply the service brakes or move the retard lever to full ON to prevent machine movement. Slowly accelerate the engine to fullthrottle for no more than 30 seconds. L Check and record engine rpm with an accurate tachometer or a remote electronic measuring tachometer. Maximum engine rpm with the con- verter stalled is 1815 t 100 rPm. 10. lf the stall rpm does not meet the listed require- ments, refer to the service guidelines below. Low rpm: . Transmission oil viscosi§ high due to low temperature, wrong oil or bad oil . Engiñe power is not within sPecs . Faulty torque converter assembly or components High rpm: . Transmission oil viscosity is low due to high temperature, wrong oil, bad oil, or lack of oil flow . Engine power is not within sPecs . Faulty torque converter assembly or components c' The transmission oil temperature must not exceed 120" C (248" n. DO NOT stall the torque converter at full throttle for more than 30 seconds at any one time- á<ceeding fhese limits may result in serious damage to converter comPonents- Prior to performing a stall test, ensure that all sys- tems such as exhaust piping, air iniake piping, fuel controls, and engine warning systems are allworking properly, and within specifications. lnsufficient fuél or resticted piping can also effect stall speed' 1. lnstall wheel chocks, and apply the parking brake. 2. Start the engine. 3. Apply and hold the service brakes fully to pre- vent movement of the machine' 4. Ensure the F1 start switch is in the OFF posi- tion. 5. Move the shift selector lever to D. Fully apply the service brakes or move the retard lever to full ON to prevent machine movement. Slowly accelerate the engine to fullthrottle for no more than 30 seconds. 6. Move the shift lever to NEUTRAL and allow the engine to idle for 30 secondb. 7. Repeat the previous two steps until the engine and transmission are at normal operating tem- perature: engine 85 - 97" C (185 '2O7" F'), transmission 70 - 90" C (158 - 194'F). 5 F2-11 ."*nr;'l:i' .-!" . :¡¡.J¡ FA2021 05/08 Torque Converter & Transmission
