Description
What does a compressor piston and ring do?
This compressor piston and ring set plays a critical role in the compression cycle of the air brake compressor, ensuring efficient air pressure generation for the braking system. These components are manufactured from high-strength materials designed to withstand the intense heat and pressure cycles typical of heavy commercial vehicle applications.Compatible vehicles and engines
This specific set is compatible with Volvo FH12 trucks equipped with D12C engines. It is engineered to meet the strict requirements of the original equipment, ensuring correct ring groove arrangement and fitment within the cylinder liner.Installation and maintenance
When performing an overhaul, technicians should verify that the 80.00mm diameter matches the current cylinder bore exactly. It is essential to inspect the ring grooves for wear and ensure that the new rings provide the correct end-gap clearance as specified in the service manual to prevent blow-by or binding.Troubleshooting and selection
Proper maintenance of the compressor assembly includes checking these components during regular service intervals to prevent air leaks or loss of pressure in the pneumatic system.OE cross-reference
7000 801 100 (Compressor Piston & Ring) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 21136656.Other OEMs

FAQ
How do I verify compatibility with my compressor?
Check that the piston diameter matches your cylinder bore exactly (80.00mm in this case) and verify that the ring groove configuration matches the original component.
What is the purpose of the ring grooves?
The upper grooves are designed to carry compression rings to maintain seal, while the lower groove typically holds an oil control ring to manage lubrication.
Can I use a standard size if my liner has been machined?
No, if a liner has been rebored or honed, an oversize piston and ring set must be used instead of this standard 80.00mm version.
What are common symptoms of worn piston rings?
Common signs include a gradual loss of air pressure in the braking system or visible oil leakage from the compressor breather.
What are the OE reference numbers of this part?
7000 801 100 directly replaces Volvo OE number 21136656.
