LAKEWOOD/QUICKTIME SAFETY BELLHOUSING
ALL TR4050 TRANSMISSIONS
INSTALLATION INSTRUCTIONS
Congratulations on your purchase of the finest quality steel bellhousing available today.
100% manufactured in the USA!
Please understand that Lakewood/QuickTime safety bellhousings are not vehicle specific.
They are designed to adapt specific engines to specific transmissions and may require you to do some minor work to make it fit your particular vehicle.
NOTICE:
Bellhousings that meet S.F.I. (Safety Foundation Institute) specification 6.1 are supplied with an engine
block plate and maximum containment fasteners that must be used. It is highly recommended that an
S.F.I.-approved flywheel and clutch assembly to be used in conjunction with these bellhousings for
additional safety precautions.
CAUTION:
Installation of this safety bellhousing requires working underneath vehicle.
USE EXTREME CAUTION WHEN WORKING UNDERNEATH THE VEHICLE.
Never get near or underneath the vehicle until you
are confident that it is safely supported and will not move or fall from its raised position.
DO NOT USE A BUMPER JACK!
All bellhousings include fasteners to mount the bell to the engine and containment hardware to fasten the block plate to
the bell on 6.1 S.F.I. approved housings.
All bellhousings are designed to use the stock factory transmission mounting bolts.
STARTER MOTORS
Bellhousings are designed to be used with factory OE starters or equivalent except where noted in our catalog.
Small compact high torque mini starters will work with all Lakewood/QuickTime bellhousings.
FLYWHEELS
Most Lakewood/QuickTime bellhousings are designed for use with factory-size flywheels, except for size limitations where
noted in our catalog.
IMPORTANT: Always check and confirm the fitment before the final installation. It is recommended to check the fit of the transmission
into the bellhousing before mounting it to the engine.
This is also a great time to bolt the block plate and flywheel to the block without the bellhousing and check your starter to flywheel engagement.
Make sure the block, block plate, bellhousing, and transmission front plate are free of chips, paint, dirt, etc.
Use a hone or sanding block to make sure all surfaces are clear of any debris.
PREPARING FOR INSTALLATION
1. Place the vehicle on a solid, level surface such as a garage floor to ensure safe installation.
2. Raise the vehicle using an appropriate lifting device and support it using automotive-approved support stands to have adequate load capacity.
3. Disconnect the negative (-) cable from the battery.
CAUTION: DO NOT BEGIN THIS INSTALLATION UNTIL YOU ARE CONFIDENT THAT THE VEHICLE IS SECURE
AND SAFELY SUPPORTED!
INSTALLATION INSTRUCTIONS:
1. Remove driveshaft, starter motor, transmission, and stock bellhousing.
2. Remove pressure plate and clutch disc from the flywheel.
3. At this point, we recommend that you check your Safety Bellhousing for proper alignment with the crankshaft.
This is not a difficult procedure. Detailed instructions outlining the necessary steps along with recommendations
for correcting any misalignment are included with these instructions.
4. After checking and correcting bellhousing alignment, remove the flywheel and install the block plate.
Use the block plate as is (the round hole in the block plate will correctly locate the starter nose assuring proper alignment).
Install block plate over the crankshaft flange and place over dowel pins in the block.
IMPORTANT: In order to comply and meet S.F.I. bellhousing specification 6.1, it is mandatory that the safety
block plate be installed with 6.1 bellhousings and all containment fasteners supplied be used.
5. Reinstall flywheel and clutch assembly. Be sure to tighten fasteners using manufacturer-recommended torque
specifications.
NOTE:
We recommend the use of Mr. Gasket Ultra-Seal premium fasteners for clutch and flywheel installation when available.
IMPORTANT:
Do not reuse the factory cast iron flywheel! A high-performance quality billet flywheel that meets S.F.I. specifications is recommended for safety purposes.
Hays offers a complete line of high-performance clutches and flywheels that meet safety requirements.
6. Position your bellhousing over the flywheel/clutch assembly and slide onto dowel pins in the engine block.
Fasten the bellhousing to the engine block using the grade 8 bolts supplied.
Make sure the fasteners supplied have the same thread size/pitch as the factory threads.
Secure the block plate to the bellhousing using the grade 8 bolts, lock
washers, and nuts supplied.
IMPORTANT:
All fasteners must be used in their proper location for the bellhousing to meet S.F.I. specification 6.1.
NOTE:
All fasteners for the engine side or transmission side should be torqued between 35 and 45 ft/lbs to maintain
parallelism.
It is more important that they are all torqued the same more than whether it is 35 or 45 ft/lbs.
7. Replace the starter motor, transmission, and driveshaft.
8. Attach clutch linkage if applicable and check for proper adjustment.
9. Reconnect battery.

BELLHOUSING ALIGNMENT PROCEDURE
Due to manufacturers’ machining tolerances of engine blocks in relationship to dowel pin location, machine shop line
honing, warpage of the block due to heat cycles over time, dirt, debris, chips on mating surfaces, interference with block
protrusions, it is quite possible for the crankshaft centerline and bellhousing bore to be misaligned. With the transmission
installed in a misaligned condition, several problems can occur, such as pilot bearing and main shaft bearing wear,
difficulty in shifting, and in extreme cases, breakage of transmission gears and case.
While most bellhousings will fall within the allowable limits, it is good practice to check for register bore run out whenever
any bellhousing or engine block is installed. Most factory service manuals will outline the checking procedure, but will not
give correctional measures necessary to ensure trouble-free standard transmission operation.
Offset dowel pins are available from Lakewood Industries to ensure correct bellhousing installation. For checking, you will
need a dial indicator (preferably with a magnetic base), a few simple tools, and close attention to detail to give you
accurate installation results.
1. Remove the clutch assembly from the flywheel and install bellhousing on the engine block.
(It is easier when you leave the clutch assembly off the flywheel.)
Torque bellhousing bolts to 35-45 ft./lbs.
2. Install the dial-indicator base on the flywheel and adjust the plunger to contact the register bore of the housing.
3. Rotate the flywheel and note the indicator reading. Misalignment is one-half of the indicator reading (the maximum
allowable for most transmissions is .005”).
4. To correct the off-center condition, select the offset dowel pin pair that is closest to one-half of the indicator reading.
(i.e., if reading is .016”, 1/2R=.008” use .007” dowels. If reading is .024”, 1/2R=.012” use .014” dowels).
5. Remove stock dowel pins by driving them out from the back side or pulling them out with gripper pliers.
6. Clean engine block dowel holes and coat lightly with lubricant.
7. Lubricate dowel pins and install them in the block.
Note the position of the offset and mark the dowel for reference.
They should be installed parallel to one another and in pairs (both .007”, .014” and .021”).
8. Install and tighten bellhousing securely. Remount the dial indicator and recheck the register bore run-out (Repeat
step 3).
9. To make small corrections or adjustments to the alignment, you will need to remove the bellhousing and drive the
offset dowels out of the block. Reposition the dowels and re-check the register bore run-out. Repeat this procedure
until the register bore is within limits.
NOTE: Always be careful when removing bellhousing from engine block so that offset dowel pins do not move or change
position.
