AIR CONDITIONING (OPTIONAL) 1B-27
Replenishing compressor oil
When replacing air conditioning parts with new ones, it is neces-
sary to replenish oil by the amount supposedly remaining in each
part.
WHEN CHANGING GAS ONLY
When it is unavoidable to change gas without replacing any com-
ponent part for engine removal and installation or for some other
reason, replenish 20 cm
3 (20cc) oil. When replenishing gas only,
oil replenishment is not necessary.
WHEN REPLACING COMPRESSOR
Compressor oil is sealed in each new compressor by the amount
required for air conditioner cycle. Therefore, when using a new
compressor for replacement, drain oil from it by the amount calcu-
lated as follows.
“C” = “A” – “B”
“C” : Amount of oil to be drained
“A” : Amount of oil sealed in a new compressor
“B” : Amount of oil remaining in removed compressor
Amount of oil in new compressor :
Dual A/C model 140 cm
3 (140 cc)
Single A/C model 100 cm
3 (100 cc)
