MERITOR® ALLFIT CLUTCHES

COMPREHENSIVE ALL-MAKES LINE-UP.
UNCOMPROMISING QUALITY.

MERITOR ALLFIT CLUTCHES. ALL-MAKES FOR
ALL YOUR APPLICATION NEEDS.
®

As a leading supplier of drivetrain systems and
components in North America, Meritor is dedicated
to bringing cost-effective clutch solutions to the
commercial vehicle aftermarket.
Our line of Meritor AllFit clutches offers solutions for a
wide variety of applications. Every AllFit clutch features
high-performance friction material, exclusive to Meritor,
for superior functionality and durability to keep you on the
road longer. Choose from two easy pedal effort models:
■ Manual-Adjust
■ Self-Adjusting

Unmatched Quality.
With AllFit-brand clutches, quality is a given. Meritor
performs a rigorous inspection of its partner-supplier
using Parts and Process Audit (PAPA) and Production
Part Acceptance Process (PPAP). And all production
and final assembly is completed in an ISO-9001
certified facility in the United States. The result: a line
of all-makes clutches that live up to the Meritor brand
reputation for high quality, high performance products.

Made in U.S.A.

Brand New Clutches From a Brand
You Can Trust.
Meritor AllFit all-makes clutches are brand-new units –
so there is never a core charge assessed and no core
handling costs.
All critical interior components are new – not
remanufactured – and meet design and quality
specifications to help ensure long service life and
outstanding performance.

SELF-ADJUSTING CLUTCHES
Meritor AllFit self-adjusting clutches are designed to
help extend service life by eliminating the downtime
typically associated with regular clutch adjustments.
The proven self-adjust technology provides smooth
efficient operation for optimum performance.
It is recommended that the self-adjusting clutches
be installed on vehicles equipped with a hydraulic
linkage system.
■ 15.5” clutch assemblies are available with 7- and
9-spring disc design with torque ratings from
1700-2050 lb-ft

How It Works.
During clutch disengagement, if release bearing travel
is 1/2” or less, no adjustment is necessary and the
built-in lost motion window ensures an optimal release
bearing position.
When the clutch wears, release bearing travel increases
beyond lost motion window and advances the worm
gear. The worm gear then turns the adjusting ring to
compensate for wear, repositioning the release bearing.
On clutch engagement, the one-way ratchet advances
and restores the ideal lost motion window.

Features and Benefits.
■ Self-adjusting clutches follow the same installation
procedure as manual-adjust clutches
■ Wider release bearing lugs and additional grease
fittings to accommodate various linkage systems
■ Patent-Pending Actively Expanding Seal (A.E.S.)
is housed in the adjusting ring to eliminate
contamination-related failures caused by road grime,
dust and other contaminants
■ Meritor-exclusive, high-performance friction material
for added durability
■ Developed and designed for efficiency and ease of
maintenance
■ Simple reset procedure utilizing manual adjuster
Will NOT Over-Adjust
■ The AllFit self-adjusting clutch will not over-adjust
and is not susceptible to outside forces (e.g. when
backing into dock or when hitting potholes during
disengagement)
Meritor Allfit Clutches Feature a Robust Adjuster Design
■ Positively engaged ratchet system
■ 4-lug drive gear has the capability to deliver over
50 lb-ft of torque to the adjusting ring
■ Self-locking worm gear ensures positive adjustment

Self-Contained Design Keeps Contaminants
Out For Smooth Operation.
Nothing slows down proper functionality faster than
road contaminants and debris. Meritor AllFit selfadjusting clutches feature advanced contaminationprevention technology to help keep them operating
smoothly.
■ Drive gear is contained within the worm gear to keep
contaminants out of the drive lugs
■ Wave spring is contained within drive arm to keep out
contaminants so that the spring can flex freely during
ratchet function
■ Self-contained components in adjuster maintain
optimal adjusting function
■ Patent-Pending Actively Expanding Seal (A.E.S.)
creates an industry-first anti-contamination enclosure

■ Specialized lubrication ensures optimal adjustments
throughout the life of the clutch
*See Meritor publication PB-1624 for complete details.

Patent-Pending Actively Expanding Seal (A.E.S.) is housed in
the adjusting ring to eliminate contamination-related failures
caused by road grime, dust and other contaminants.
Specialized thread lube is used to reduce friction in adjusting
ring/cover threads and to prevent rust and other corrosion
issues resulting in premature failure.

MANUAL CLUTCHES
Meritor AllFit manual-adjust clutches deliver more
comfortable operation for the driver and a better bottom
line for your fleet.
We offer a broad range of manual clutch options to
accommodate a spectrum of applications, including
heavy-duty and medium-duty vehicles, off-highway,
construction and off-road.

14” and 15.5” Easy Pedal Effort Clutches.
■ 14” clutch assemblies for medium-duty applications
are available with torque ratings from 620 to
1400 lb-ft.

High-Torque Easy Pedal Clutch.
The AllFit high-torque, high plate-load clutch is
designed for heavy-duty truck and severe service
applications and is ideal for off-road and oversized
loads. The high-torque model helps reduce severe
vibration while extending drivetrain component life for
lower maintenance costs and less downtime.
■ 15.5” clutch assembly with 7-spring disc design with
2250 lb-ft torque rating

Features and Benefits.
■ 15.5” clutch assemblies are available with
7-, 8-, 9- and 10-spring disc designs with torque
ratings from 1250 to 2250 lb-ft.

for superior strength
■ For better process control and inventory analysis, all
Meritor AllFit clutches are serialized and shipped as
matched units
■ Many 9-spring Mack applications are covered by our
easy pedal effort clutches

■ Disc designed for superior vibration control
(dampening) provides reduced drivetrain torsional
rate in the most demanding applications
■ A heavier duty back plate keeps springs from
wearing faster which cuts down on maintenance time
and improves longevity
■ Patented lever provides higher plate load without
higher pedal pressure
■ EZ Adjuster – ratcheting adjuster with 5/8” bolt head
■ Meritor-exclusive, high-performance friction material
for superior robustness
