T417956 Piston Kit For Perkins C7.1 Diesel Engine Excavator Overhaul Kit Full Gaskets

PRODUCT SPECIFICATIONS

Perkins C7.1 engine overhaul component set

一:Core component composition (compatible with C7.1 engine)

1:Piston assembly (the silver piston in the blue packaging in the picture) : It includes a brand-new aluminum alloy piston + piston ring set (air ring + oil ring), solving problems such as piston wear and oil burning.
2:Cylinder liner (the independently packaged cylinder barrel in the picture) : Replacing the worn cylinder wall and restoring the cylinder's sealing performance, it is a fundamental component for major overhauls.
3:Sealing parts set (black/rubber gasket in the picture) : It includes cylinder head gasket, oil pan gasket, front and rear end cover gasket, etc., ensuring the sealing of each chamber of the engine (preventing water leakage, oil leakage, and air seepage).
4:Bearing bush accessories (small packages) : including connecting rod bearing shells and main shaft shells. Replace worn bearing shells to restore the lubrication clearance between the crankshaft and the connecting rod.
5:Auxiliary components: As shown in the figure, the oil pump (silver gear part), oil seal (green sealing ring), etc. can be seen. Simultaneously replace the vulnerable lubrication/sealing components.

二. Applicable Scenarios and Values

The C7.1 engine is widely used in excavators (such as CAT 320 and Komatsu PC200), loaders, generator sets and other equipment. When the engine experiences serious faults such as sudden power drop, oil burning, cylinder pulling, abnormal crankshaft noise, and abnormal oil pressure, this set of major repair parts needs to be used for in-depth maintenance.
By replacing all the core worn parts, the performance and reliability of the C7.1 engine can be restored to a state close to that of a new machine, significantly extending the service life of the equipment. It is a key supporting solution for the engine refurbishment of heavy equipment.
