Maintaining a marine transmission like the TMP (Thamesway Marine Products) Type 12000 series requires technical precision and a deep understanding of its unique hydraulic and mechanical architecture. These gearboxes, originally produced by manufacturers like Thames Marine Propulsion and Henry Meadows, are heavy-duty units that demand specific procedures for overhaul and service. Essential Technical Specifications

Before beginning any workshop repairs, confirm the specific model from the serial plate located on top of the gearbox. tmp gearbox workshop manual top

Lubrication: Use only SAE #30 engine oil. Avoid multi-grade oils (e.g., 10W40), as they can negatively impact the coefficient of friction and cause clutch slippage.

Operating Pressure: The system typically operates at approximately 80 psi to engage the conical clutch plates.

Rotation: Most TMP 12000 units are designed for right-hand rotation engines. Note that direct-drive models turn the propeller in the same direction as the engine, while reduction boxes may vary based on the number of pinions used. Critical Maintenance and Assembly Components

A full overhaul requires specific replacement parts to ensure the integrity of the hydraulic seals and mechanical drive. Component Type Part Number / Requirement Input Seal Prevents oil leaks at the bell housing interface. Output Seal Seals the output shaft for direct drive units. Gasket Kit Includes essential O-rings for pressure integrity. Brake Pad Neutral brake pad for stopping shaft rotation. Oil Filter TM 12009 / 12773 Models differ between MK II and MK IV versions. Step-by-Step Workshop Procedures 1. Removal and Disengagement

The gearbox is typically attached to the engine bell housing by internal nuts. You must remove the gearbox and bell housing as a single unit.

Engine Support: Since the bell housing often carries the rear engine mounts, ensure the engine is properly supported before unbolting.

Disengagement: A rearward movement of approximately 2.0 inches is usually required to clear the input shaft. For Mercedes-based installations, this may increase to 6.0 inches. For those maintaining or rebuilding a TMP (Thamesway

Frozen Bushes: If the 8-bush input is seized due to rust, experts at Thamesway Marine Products suggest cutting a small access hole in the housing to apply lubricant and leverage the flywheel directly. 2. Inspection for Wear

During disassembly, pay close attention to the following high-wear areas:

Clutch Linings: Ahead linings often show "gramophone groove" witness marks. Modern replacement linings require professional bonding.

Oil Pump: Check the pressure plate face and gears for ovality. Excessive wear here leads to a "flicking" pressure gauge or total loss of drive.

Planet Gears: Inspect the bushes and shafts. Wear in this area is a primary cause of excessive noise. 3. Reassembly Best Practices TMP gearbox assembly DIY | YBW Forum

1. The 3rd Gear Pop-Out Fix (TMP-660 Model)

Symptom: Transmission jumps out of third gear under load. Standard manual advice: Replace shift fork. Top manual truth: The manual reveals a hidden bulletin—a worn detent spring guide bushing. The "Top" guide shows how to drill a 2mm oil relief hole in the bushing. This permanent fix is not listed anywhere else.
