Accumulator Service Evaluation
Inspect bore of accumulator cylinder for score marks or
wear. If barrel of accumulator is not scratched or scored,
it can be reused. If bore is scored or damaged, it will
require resurfacing and nickel plating. If cylinder bore is
damaged, it may be more cost effective to replace the
complete accumulator than to continue this repair.
