• Keep the tools clean and in good condition. • Always use HYSTER APPROVED parts when making repairs. Replacement parts must meet or ex- ceed the specifications of the original equipment manufacturer. • Make sure all nuts, bolts, snap rings, and other fastening devices are removed before using force to remove parts.

The activated magnet coil attracts the ac- tuator ring which is connected with the valve through a pin.
0700 SRM 1595 Cooling System Clutch engagement is also influenced by actual vis- cosity of the viscous oil. Engagement is higher at lower temperatures. Engagement is lower at higher temperatures. The ECM compensates for differen- ces in engagement, but at extremely cold tempera- tures the normally lowest engagement of 30% may remain at a higher level because of the higher vis- cosity.
Cooling System 0700 SRM 1595 Engine Cooling System During operation of the truck, heat is generated in the engine. The engine cooling system regulates the dissipation of this heat in order to maintain the en- gine at the desired operating temperature. The coolant is pumped in a closed circuit, where it ab- sorbs heat from the engine and dissipates heat in the cooling core.

Cooling System 0700 SRM 1595 grades over time, but degrades more rapidly with a pH below 7.0. When ethylene glycol degrades, acidic components are formed, which rapidly lower the pH. Additives in the coolant compensate for the negative effects of degrading ethylene glycol.

0700 SRM 1595 Service and Repair Take a small quantity of coolant from the ex- pansion tank and pour it into a sight glass. Coolant should be a clear fluid without cloudiness, floating debris or oil. Oil in the coolant, cloudiness, or floating debris indi- cates a possible head gasket or cylinder liner defect.
