REPLENISHING COMPRESSOR OIL
When replacing air conditioning parts with new ones, it is necessary
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 compo-
nent part for engine removal and installation or for some other rea-
son, replenish 50 cc oil. When replenishing gas only, oil replenish-
ment 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
