Mercury Belt Tensioner Assembly
Mercury 8M0164060 Tensioner Assembly
The Mercury 8M0164060 Tensioner Assembly is used in the belt drive system to help maintain proper belt tension and pulley alignment. A worn tensioner or pulley can lead to belt noise, slipping, uneven belt wear, or charging and accessory drive issues.
When replacing this tensioner assembly, it is usually a good idea to inspect and replace the belt at the same time. The related Mercury 8M0159595 belt is linked below.
Compatible Applications
| Engine / Application | Part Number |
|---|---|
| Mercury 450R V8 belt drive system | 8M0164060 |
Verify your engine serial number and original tensioner part number before ordering. Mercury belt drive components can vary by model and serial range. The related belt listed by Pro Marine is identified as fitting Mercury 450R V8.
OEM & Cross Reference Numbers
| Type | Part Number |
|---|---|
| Mercury OEM | 8M0164060 |
Related Belt Replacement
Mercury 8M0159595 Belt - Mercury 450R V8
It is common to replace the belt when servicing the tensioner or pulley. A worn belt can cause slipping, noise, poor charging performance, or premature wear on the new tensioner assembly.
What This Part is Used For
The belt tensioner assembly keeps proper tension on the engine belt so the belt can drive related engine accessories correctly. If the tensioner weakens, binds, or the pulley wears out, the belt may slip, squeal, track incorrectly, or wear faster than normal.
Replacing the tensioner assembly helps restore proper belt control. Because the belt rides directly on the pulley system, replacing the belt during the same service is often recommended.
Key Features and Benefits
- Mercury OEM tensioner assembly
- Part number 8M0164060
- Helps maintain correct belt tension
- Supports proper belt tracking and accessory drive operation
- Useful when repairing belt noise, slipping, or pulley wear
- Related Mercury 8M0159595 belt linked above
- Recommended to inspect or replace the belt during tensioner service
Common Signs of a Worn Tensioner or Belt
| Symptom | Possible Cause |
|---|---|
| Belt squeal or chirping | Weak tensioner, worn pulley, glazed belt, or misalignment |
| Visible belt wear | Pulley wear, improper tracking, or old belt |
| Belt slipping | Loss of tension or worn belt surface |
| Pulley noise | Worn bearing or damaged tensioner pulley |
FAQ
What is the OEM number for this tensioner?
The OEM part number is 8M0164060.
Should I replace the belt when replacing the tensioner?
Yes, it is usually recommended to inspect and replace the belt when servicing
the tensioner or pulley, especially if the belt shows wear, glazing, cracking,
noise, or slipping.
Which belt goes with this tensioner?
The related belt is Mercury 8M0159595, linked above.
What does the tensioner assembly do?
It keeps the engine belt under proper tension so the belt can drive related
engine accessories correctly.
Can a bad tensioner damage a new belt?
Yes. A worn or misaligned tensioner can cause premature belt wear, belt noise,
or belt tracking problems.
Do I need to verify fitment?
Yes. Always verify your engine serial number and original part number before
ordering Mercury belt drive components.
