MultiStar Cold – Your Source for Bus Air Conditioner Parts
The Bock 80017 oil pump is a built-in rotary lubrication pump for Bock FK40 and FKX40 series reciprocating compressors for bus & coach air conditioning. This bidirectional oil pump delivers pressurized lubricant to crankshaft journals, bearings and moving piston assemblies. It prevents metal-to-metal contact, reduces friction and overheating. Ideal replacement when original oil pump fails, causes low oil pressure, bearing wear or compressor seizure during mobile operation.
Multistar Cold is your one-stop supplier for bus AC parts and transport refrigeration parts – original new and China-made options at competitive prices.
