TECH TIPS
CLUTCH/TRANSMISSION
INSTALLATION TIPS
1986 and newer V-8 Mustangs
The flywheel to crankshaft bolts must be
hand-torqued to 75-85 ft./lb. (302/351W)
and 54-64 ft./lb. (4.6L)
The 10.5" pressure plate bolts must be torqued
to 12-24 ft./lbs. and 11" pressure plate bolts
to 33 ft./lbs. + 1/4 turn.
Be sure to use the alignment dowels
in the flywheels.
Pressure plate bolts and alignment dowels
for the 10.5" clutch can be purchased using
PN M-6397-A302. Pressure plate bolts
N808969-S100 and alignment dowels
PN D1FZ-6397-B are for the 11" pressure plate.
Evenly tighten bolts in a circular direction
one turn at a time.
Bellhousing alignment is crucial for proper
clutch and transmission function.
Due to production tolerances of engine
blocks and bellhousings, it is possible for
the transmission centerline and crankshaft
centerline to be misaligned. Misalignment can
cause transmission gear wear, transmission
jumping out of gear, driveline vibration, clutch
pedal vibration, pilot bearing noise, release
bearing noise or excessive clutch spin time.
It may also damage the pilot bearing,
transmission mainshaft bearing and clutch hub.
It will also cause harsh shifting.
Before installing the bellhousing, check
the block mounting surface and bellhousing
surfaces for nicks, dents, paint debris, etc.
These are some things that could affect
the accuracy of your measurements.
HOW TO CHECK BELLHOUSING ALIGNMENT
The first step is to check bellhousing face runout. You are checking for parallelism of the
back of the bellhousing to the back of the block. Install the dial indicator (as shown in Fig.1).
Rotate the crankshaft and mark down the reading. Be sure to push the crankshaft against
the thrust bearing for an accurate reading. Maximum runout is .010. The next step is checking
bellhousing bore runout. You are checking to see if the bellhousing bore centerline is aligned
with crankshaft centerline. Reposition the dial indicator in the bellhousing bore (as shown in Fig. 2).
Rotate the crankshaft and mark down the readings. Maximum out of concentricity is .015.
If the bore runout is out of spec. install appropriate offset dowels.
Offset alignment dowels can be purchased from Lakewood.
