21086642 Bracket | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta structural support bracket for the engine-driven air-compressor/PTO installation. On the TAD761VE parts list for your engine it forms part of the compressor, gear, oil-pipe and coolant-pipe mounting group. The bracket's machined and formed mounting points position the compressor so the drive gear meshes correctly and the connected pipes are not placed under strain.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD765VE
• Volvo Penta TAD764VE
• Volvo Penta TAD763VE
• Volvo Penta TAD762VE
• Volvo Penta TAD761VE

• Engine Family: TAD

⚙️ Key Features

• Heavy-duty support bracket for the compressor/PTO assembly
• Controls compressor position and drive-gear alignment
• Provides the correct mounting points for associated pipes and hardware
• OEM stiffness limits vibration and housing movement under compressor load
• Requires the specified spacers, screws and gasket arrangement
• Engine type: D5/D7-series industrial diesel with optional engine-driven air compressor/PTO

🔌 Function

Supports and accurately locates the compressor assembly, maintaining drive-gear mesh, pipe alignment and structural stability under torque reaction and engine vibration.

⚠️ Common Signs of Failure

• Cracking around mounting holes or formed sections
• Compressor movement or abnormal vibration
• Drive-gear whine caused by misalignment
• Repeated oil or coolant-pipe fatigue failures
• Mounting fasteners that will not retain torque

🛠️ Service Notes

• Offer the bracket up and start every fastener by hand before tightening any of them, so the component is not pulled into a strained position
• Check the mating faces are clean, flat and free of corrosion scale — a bracket that does not sit flat will work loose and let the component move
• Renew self-locking nuts, lock washers, tab washers or thread-locking compound wherever the original assembly used them, and tighten to the figure given in the workshop manual for your engine
• Where the bracket carries a rubber mount or bush, renew that at the same time rather than reusing a perished one
• On brackets in the inlet and exhaust area, never force alignment to make the holes line up — cure the misalignment at its source, or the bracket and the component it holds will both crack
