PROBLEM
Show/hide table
| The HVAC air ducts provide poor cab cooling performance on certain 320C, 320D, 322C, 324D, 325C, 325D, 330C, and 330D Forestry Machines. The existing HVAC ducts provide poor airflow to the operator and result in a less comfortable work environment for the operator. |

Remove the existing mode control feature from the HVAC unit and add a manual heater control valve into the heater supply line. Refer to the rework procedure in REHS5401. The D-Series Forestry Machines (Group 2 machines) also need the air conditioning system recharged. Recover the refrigerant, install a new 176-1902 receiver-dryer, and recharge the refrigerant to the amount listed. Follow the procedure provided in SENR5664 for recovery and recharge procedures. Machine Charge Amount 320D 1.1 kg (2.43 lb) 324D 1.1 kg (2.43 lb) 325D 1.1 kg (2.43 lb) 330D 1.2 kg (2.65 lb) Locate and remove the existing 110-6393 plate listing the refrigerant amount. Install a new 110-6393 instruction plate and stamp the refrigerant kg charge amount for the machine into the plate. |
