Drive Clutch Disassembly - EBS
CLUTCHES
Engine Braking System (EBS)
NOTE: Most of the disassembly and inspection procedures for the EBS drive clutch are the same as with a stan-
dard PVT drive clutch. This section will cover only the disassembly and inspection procedures unique to the EBS
drive clutch. Assembly notes are included when different from standard PVT assembly procedures. Refer to page
6.17 -6.22 for information common to both the standard and EBS type.
Drive Belt Removal- EBS
1. Mark the drive belt direction of rotation and remove
drive belt. The belt is normally installed so the
numbers can be easily read. To remove drive belt,
push moveable sheave inward to open driven
clutch sheaves, push down on belt to hold sheaves
open, and slip belt over driven clutch outer sheave.
One-Way Clutch Inspection (Drive Clutch)
1 . Rotate one-way clutch clockwise (as viewed from
the cover plate side). The clutch should rotate on
the shaft with only slight amount of drag. There
should not be any binding or rough spots. When
rotated counterclockwise, the clutch should lock to
the shaft without slipping. If problems are noted in
either direction, continue with disassembly.
2. Remove drive clutch. Refer to page 6.9.
3. Remove spider assembly. Refer to page 6.19.
NOTE: SPIDER TORQUE: Torque EBS drive clutch spi-
der to 180-190 ft. Ibs. (24.9-26.3 Kg-m) upon assembly.
4. Remove spacer sleeve and the 2" PTFE washer.
Visually inspect the washer for damage. Measure
the thickness and compare to specification.
Replace if worn or damaged.

NOTE: Some early EBS drive clutches use two wash-
ers beneath the spacer sleeve. Late production use only
one. Reinstall the same number as were removed. If you
are not sure how many were removed measure the depth
of the spacer sleeve and refer to the chart below.
