Revised Concise Version For 7260/10300, 334/P6417, 332/L2338 Roller Drum Gearbox

7260/10300, 334/P6417 & 332/L2338 are 3-stage integrated planetary travel gearboxes, direct OEM replacements for JCB Vibromax VM115D & VM200 single drum compactors. Equipped with 1:1 OEM mounting flanges, standard hydraulic ports, high-pressure seals and built-in 2-speed piston motors, they feature carburized ground planetary gears and reinforced bearings to deliver steady high torque during heavy compaction and climbing. All dimensions, ports and splines match original units perfectly for plug-and-play installation without machining or pipe adjustments.

This high-torque one-piece drum drive assembly powers JCB VM series roller drums. It runs at 340 bar rated pressure with 370 bar peak pressure, maintaining stable performance under long full-load compaction cycles. Ideal for highway subgrade, asphalt and municipal road compaction, it resists shock and vibration well with alloy housing and reinforced output bearings, adapting to dusty, muddy construction sites.

Custom upgrade options include optimized gear profiles, heavy-duty seal kits, adjustable speed ratios and strengthened splines, fully compatible with original hydraulic systems of VM115D/VM200. No extra adapters are needed for seamless drum connection. It is the perfect compact high-torque drive solution for vibratory rollers, widely used in all road infrastructure compaction works.

Q: What machine does the 7260/10300, 334/P6417, 332/L2338 drum gearbox fit?

A: These three interchangeable part numbers belong to one integrated drum travel planetary gearbox, specially designed for JCB Vibromax VM115D and VM200 single drum vibratory rollers, serving as the core drive assembly for the roller steel drum.

Q: Is it a direct OEM replacement?

A: Yes. All mounting flanges, bolt holes, splines, oil port positions and overall dimensions are 1:1 OEM matched. No cutting, drilling or modification is needed, supporting direct plug-and-play installation.

Q: What are the core technical parameters?

A: Rated working pressure: 340 bar; peak pressure: 370 bar; max output torque: 48500 N·m. It adopts a 3-stage planetary transmission structure with built-in two-speed hydraulic motor, suitable for heavy-duty compaction and steep slope climbing operations.

Q: Is it fully compatible with the original hydraulic system?

A: Fully compatible. This integrated gearbox matches the original hydraulic drive system of JCB Vibromax VM115D/VM200 rollers perfectly. No transition adapters are required, ensuring stable driving performance and consistent working efficiency.

Q: Does this gearbox support two-speed adjustment?

A: Yes. It integrates a built-in two-speed piston motor, supporting low-speed high-torque heavy compaction and high-speed traveling transfer, meeting diverse construction and transit demands.

Q: Are customized upgrade options available?

A: Yes. We support upgraded solutions including reinforced alloy gear sets, heavy-duty full sealing kits, enhanced load-bearing bearings and high-torque splines for harsh construction conditions.

Q: What lubricants and maintenance cycles are recommended?

A: Use GL-5 85W-140 heavy-duty gear oil and 46# anti-wear hydraulic oil. Inspect oil quality and seals every 300 working hours; replace gear oil completely every 500 working hours to ensure stable operation.

Q: How to solve common leakage and overheating problems?

A: Minor leakage can be fixed by evenly tightening mounting bolts. Severe leakage requires replacing the full sealing kit. Overheating is usually caused by deteriorated oil, insufficient oil volume or internal gear wear. Regular maintenance is recommended, and unauthorized disassembly is prohibited.

Q: What is your warranty policy?

A: We offer a 12-month factory warranty. Free technical support and component replacement are provided for non-human damage under standard installation and operating conditions.
