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 100cc oil. When replenishing gas only, oil replen-
ishment 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” = “D” – “E”
“C”: Amount of oil to be drained
“D”: Amount of oil sealed in a new compressor “A”
“E”: Amount of oil remaining in removed compressor “B”
1. New compressor
2. Removed compressor
3. Excess oil (A–B)
