Hoist & reconnect the engine
Part 1. Preparation and safetyObjective
- Hoist and reconnect the engine.
Personal safety
Whenever you perform a task in the workshop you must use personal protective clothing and equipment that is appropriate for the task and which conforms to your local safety regulations and policies. Among other items, this may include:
If you are not certain what is appropriate or required, ask your supervisor.
- Work clothing - such as coveralls and steel-capped footwear
- Eye protection - such as safety glasses and face masks
- Ear protection - such as earmuffs and earplugs
- Hand protection - such as rubber gloves and barrier cream
- Respiratory equipment - such as face masks and valved respirators
Safety check
Points to note
- Take care and use the correct lifting technique when lifting heavy loads.
- Make sure that you understand and observe all legislative and personal safety procedures when carrying out the following tasks. If you are unsure of what these are, ask your supervisor.
- Ensure the workspace around the vehicle and engine bay are clear and clean with the chassis securely positioned to receive the engine.
Part 2: Step-by-step instruction
- Check engine bay
Whether or not your engine bay has been modified, cleaned or restored in any way, you need to check it very carefully. Take a moment to look over your removal notes and diagrams or photos. Make sure the workspace around and under the car is clean and the chassis securely positioned once again, and keep a basic set of tools nearby.- Installing with or without the transmission
If the automatic transmission was left in the chassis, it should be supported back in its up position. If you have a new torque converter it should be filled with Automatic Transmission Fluid and be back in place.
If you are hoisting the engine and automatic transmission together, you should have fluid in the torque converter, but none in the transmisssion. That way, none will leak out the rear tailshaft while it's angled for the install. If you have a manual transmission, don't try to install the block only and mate to a manual transmission that's in the chassis already. It is very difficult to get everything to match up from under the car. It is possible to fit an automatic transmission to an already installed block with a transmission jack, but it's not an easy procedure, and not recommended. It is simpler to install a combined unit or have the automatic transmission already in place.- Re-install the engine
Re-install the hoisting chain or plate. If the hood was removed, there will be enough room to use an engine levelers, which will help if you're installing an engine and transmission together.
Raise the motor and carefully roll it in. Control the hoist from the rear to keep yourself safely away from the motor in case a chain or lifting plate bolt breaks. Go very slowly as you lower the engine into the bay. Just lower a little and adjust the hoist, lower some more...adjust again. If you have the transmission connected, it will take a lot of adjustments of the angle of the assembly to get it to clear. At this extreme angle automatic transmission fluid will leak out, so don't put any into the transmission before installation. As the engine gets closer to its mounts, look under the car to make sure the exhaust and everything on the underside is clear.- Align engine with transmission
If you're trying to match up to an existing transmission, go very slowly and check often to get the motor and the transmission to line up.
Make sure any wires at the rear or sides of the block are clear and angle the block to match the angle of the transmission bellhouse. Then adjust the angle and height of the motor to guide the alignment pins at the back of the block into the alignment holes in the transmission bellhouse. When both pins are lined up with the holes, give the hoist a firm push against the transmission and the block should mate with the bellhouse.
If the dowels are still not aligned correctly, make some slight adjustments up or down and push the hoist again.
Once the block and transmission mate, install the lower and mid bellhouse bolts and tighten them. While the engine is still suspended, keep away from under the engine itself. When the bolts are tight, remove the transmission shims and lower the engine on to its mounts.- Secure engine to mounts
Sometimes the mounts are difficult to align and it seems like the engine position needs to move toward the rear of the chassis to allow the mounts to drop in place. If this happens, either loosen the lower halves of the mounts on the frame, loosen the bolts that hold the transmission to it's frame crossmember, or pry the lower halves over as someone else slowly lowers the motor. You may need to do all three if the alignment is still difficult. As a last resort, loosen the bellhouse bolts a few turns if it's still too tight. These adjustments should let the engine drop down onto its mounts. Put back and tighten everything you had to loosen and then roll the hoist away.
