Introduction

Standard Single-Reduction Carriers
Meritor single-reduction standard carriers, Figure Below, are used in most Meritor
single axles, rear of tandem axles and front drive steering axles. The single-reduction
carrier models are front mounted into the axle housing. These carriers have a hypoid
drive pinion and ring gear set and bevel gears in the differential assembly.
A straight roller bearing (spigot) is mounted on the head of the drive pinion. All other
bearings in the carrier are tapered roller bearings.
When the carrier operates, there is normal differential action between the wheels all the
time.
