Restore the hydraulic power and structural reliability of your breaker with the Merit Premium Replacement Cylinder. As the heart of the Sandvik BR4099i (also known as the Rammer 4099), the cylinder guides the striking piston and handles high-pressure oil distribution. Part number 160002 is engineered to withstand the extreme thermal expansion and hydraulic shock cycles typical of 35–55 ton carriers.

Why Choose the Merit 160002 Cylinder for Sandvik?
The BR4099i is a heavy-duty breaker used in the toughest quarrying environments. Any misalignment in the cylinder can lead to catastrophic failure. Merit cylinders provide:
1. Precision-Honed Internal Bore
The internal walls of the 160002 cylinder are honed to a mirror finish. This reduces friction with the Striking Piston (151945), preventing “scuffing” and ensuring that 100% of the hydraulic pressure is converted into impact energy.
2. Advanced Pressure Retention
All seal grooves and valve ports are CNC-machined to exact tolerances. This ensures that the Seal Kit (152843) fits perfectly, eliminating internal pressure bypass. This is critical for maintaining the high strike frequency the BR4099i is famous for.
3. Stress-Relieved Forged Steel
Using premium forged alloys, our cylinders undergo specialized heat treatment to improve “fatigue resistance.” This prevents the hairline cracking that often occurs around the high-pressure ports of standard aftermarket cylinders during long-shift operations.
Maintenance Tip: Protecting the 160002 Cylinder
The cylinder is the most valuable structural component of your hammer. To extend its life:
- Cleanliness is Critical: Hydraulic contamination is the #1 cause of cylinder scoring. Ensure your excavator’s hydraulic filters are changed according to the service manual.
- Tie Rod Tension: Check the torque on your Tie Rods (152111) every 50 hours. If the tie rods are loose, the cylinder can “breathe” against the front head, leading to warped sealing surfaces.
- Inspect the Bore: If you are performing a seal change, visually inspect the cylinder bore. If vertical scratches are deep enough to catch a fingernail, the cylinder should be honed or replaced to prevent immediate failure of the new seals.
