most commonly caused by not locating the torque converter drain plug properly in the flexplate.
Warning excessive torque converter charge pressure can force the crank forward, damaging the engine thrust
bearing and the transmission. Damage to the thrust bearing can happen in seconds!
TRANSMISSION
The M-6007-X2303E comes equipped with a 157-tooth manual transmission flywheel.
Sealer is required on the small block flywheel to crankshaft bolts. Torque to 75-85 ft-lb. Over torqueing will distort
rear main seal area and cause leakage.
A starter index plate (included) is required between the block and transmission bell housing (all applications).
Be sure to install pressure plate alignment dowels if your pressure plate requires them.
For other transmission applications requiring different flywheels, see catalog or call the Techline for
other applications.
Verify that a pilot bearing is installed for all manual transmission applications. If using an automatic transmission,
be sure the pilot bearing is removed.
Verify proper bellhousing alignment on manual transmission applications. See bellhousing alignment.
Check crankshaft endplay of your engine before installing the transmission. After installing the transmission, check
crankshaft endplay. The number before and after installation should be the same. If endplay number is not the
same, this indicates that the components are incorrect, or improperly installed or damaged.
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. 2). 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. 3). 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 are available from Lakewood.
