PSR Manual Primary Chain Tensioner

TAKE CONTROL OF YOUR PRIMARY CHAIN TENSION.

Your primary drive is a critical part of your Harley-Davidson's drivetrain. Proper chain adjustment matters.

The PSR Manual Primary Chain Tensioner gives riders and mechanics a heavy-duty, manually adjustable alternative to the factory primary chain tensioning setup on compatible Harley-Davidson motorcycles.

Precision-machined from billet aluminum and equipped with a Delrin slider, this tensioner is designed for straightforward adjustment and dependable mechanical operation.

Instead of relying on an automatic tensioning mechanism, a manual tensioner allows the installer to set primary chain tension according to the motorcycle manufacturer's specifications.

Available in Black and designed to mount using OEM hardware.

MANUAL ADJUSTMENT. PRECISION-MACHINED CONSTRUCTION. CONTROL OVER YOUR PRIMARY SETUP.

Why Upgrade to a Manual Primary Chain Tensioner?

Primary chain tension plays an important role in how your Harley's primary drive operates.

A chain that is too tight can place unnecessary stress on drivetrain components, while a chain that is too loose can create excessive movement and other operating issues.

The PSR Manual Primary Chain Tensioner allows the installer to adjust chain tension manually rather than depending on an automatic adjustment mechanism.

This makes it a practical option for riders and mechanics who prefer a manually adjustable primary drive setup.

Key Features

• Heavy-duty manual primary chain tensioner

• Quick and easy adjustment design

• Allows manual control over primary chain tension

• Precision-machined billet aluminum construction

• Durable Delrin chain slider

• Mounts using OEM hardware

• Available in Black

• Fitment options for select Harley-Davidson Twin Cam and Milwaukee-Eight models

Built for riders who want a more hands-on approach to primary drive maintenance.

Manual Adjustment. No Guesswork About Who's Setting the Tension.

The PSR Manual Primary Chain Tensioner is designed to make primary chain adjustment straightforward.

With a manual tensioner, the installer sets chain tension directly and can inspect and readjust it as required during routine service.

This is especially appealing to riders who prefer maintaining their motorcycles themselves or working with a mechanic who specializes in Harley-Davidson drivetrains.

Why Manual Adjustment Matters

• Provides direct adjustment of primary chain tension

• Allows tension to be set during service

• Makes it possible to inspect and correct chain adjustment as needed

• Offers an alternative to an automatic tensioner

• Supports a more hands-on maintenance approach

The advantage is adjustability—not freedom from maintenance.

Manual tensioners require correct initial setup and periodic inspection.

Precision-Machined Billet Aluminum Construction

The PSR Manual Primary Chain Tensioner is precision-machined from billet aluminum.

Its heavy-duty construction is designed for use in the motorcycle's primary drive assembly.

The billet body provides a durable foundation for the adjustable tensioning mechanism while maintaining a clean, purpose-built appearance.

Delrin Slider for Primary Chain Contact

The tensioner features a replaceable Delrin slider at the chain contact surface.

Delrin is an engineering plastic commonly used in mechanical components requiring dimensional stability and low-friction contact characteristics.

In this application, the slider provides the surface against which the primary chain operates.

As with other primary drive wear components, the slider should be inspected and serviced according to the manufacturer's recommendations.

Uses OEM Mounting Hardware

The PSR Manual Primary Chain Tensioner is designed to mount using the motorcycle's original equipment mounting hardware.

This simplifies the mounting arrangement for compatible applications.

Note: Inspect all original hardware before reuse and follow the applicable service instructions. Replace damaged or unsuitable hardware as required.

Installation & Maintenance

The primary drive is a critical part of your motorcycle's drivetrain.

Correct tensioner installation and chain adjustment are essential.

Before Installing

1. Confirm the tensioner is compatible with your motorcycle.

2. Follow the PSR installation instructions and applicable Harley-Davidson service manual.

3. Inspect the primary chain, sprockets, mounting hardware, and related components.

4. Install the tensioner using the specified mounting arrangement.

5. Adjust primary chain tension to the applicable manufacturer's specification.

6. Check chain movement and clearance through the required inspection procedure.

7. Recheck adjustment after installation and during scheduled maintenance.

Do not overtighten the primary chain.

Incorrect chain tension can cause accelerated wear or damage to primary drive components.

A manual tensioner requires periodic inspection and adjustment. It is not a self-adjusting or maintenance-free component.

If you're unfamiliar with primary drive service, have the installation performed by a qualified motorcycle technician.
