21840806 — Trim Cylinder End Cap Gland 3888301 3887960 21840806 Fsm032 For Volvo Penta Engine Dph Dpr

This trim cylinder end cap gland is a critical seal within the hydraulic system, preventing fluid leakage and maintaining pressure for cylinder operation. It is manufactured from durable materials to meet OEM standards, offering superior resistance to wear and hydraulic fluid degradation compared to a worn seal. Operators may notice slow or jerky cylinder movement, or a loss of hydraulic fluid as signs of a failing gland.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The initial symptom of a failing trim cylinder end cap gland is often a slow leak of hydraulic fluid from the cylinder. If left unaddressed, this can lead to a gradual loss of trim control and increased wear on other hydraulic components. Continued operation with a leaking gland can result in system contamination and potential damage to the hydraulic pump.

Installation Tip

Carefully inspect the cylinder bore for any scoring or damage that could compromise the new seal's effectiveness before installation. Ensure the gland is seated squarely and not cocked, which can lead to immediate leakage.

Service Note

Inspect the hydraulic fluid level and condition, and check the trim cylinder rod for any signs of damage when replacing the end cap gland.
