BobCat E35 – COMPRESSOR – Oil

The compressor (Item 1) [Figure 70-50-11] is factory filled with 150-170 cc’s of PAG 100 refrigerant oil
(Polyalkelene Glycol).

It is not necessary to frequently check or change the compressor oil.

It is necessary to check, replenish or replace the compressor oil in the following cases:
1. When the evaporator, condenser or receiver-drier is replaced.
2. When refrigerant has leaked from the system.
3. When refrigerant is suddenly released from the cooling cycle.
4. When any oil related problems occur in the cooling cycle.

When one of the components (the evaporator, condenser or receiver-drier) is replaced, one ounce (30 cc) of PAG oil should be added for each component replaced.

If the A/C compressor is changed, no oil should be added to the system, the compressor comes factory filled with oil.

NOTE: Only PAG 100 oil should be used. Never mix R-12 and R-134a Oils.
