Engine drop
 
Hello guys,

I am about to drop the motor in order to replace clutch and other components. Yes. this is my first 6 drop. This morning I have put the car on the stands and noticed that's the highest I could get. Please see the pix and hopefully you guys can tell me if this is high enough to take the motor out. I understand I need to remove the bumper at this height.

Thanks in advance,

BW:)

Hi BW, I admire your courage for taking on this kind of task with just jackstands. I am also going to drop mine for a clutch repair but has been procrastinating even though I have a 2-post lift. I finished the rear wheel bearing change though this weekend while the axles were out.

I would suggest that you get the 6-ton jackstands which will give you more lift and capacity and a lot safer than those skinny ones you are using. I will not trust those. How are you going to support the engine? ATV jack or a regular floor jack? The car clearance height will depend on the minimum height of your ATV or floor jack.

I guess you could find using the search (or will from more reply) the exact numbers but having just drop mine using a scissor lift, I think you need quite a bit more. If I remember from previous reading, its around 40 inches.

rsr91128 01-30-2011 05:03 PM

993 instead of a 64 but I think it is close to the same height required. With my jackstands (similar to your front stands) on the highest point and the bumper off I still had to disassemble the ISV to clear on the way out. The jackstands were at 21.5" not sure what that equaled at the bumper but you get the idea.

Have fun with it! Make sure you put your wheels or something under the car when you are working on it just in case.

Thanks for your comment and I admire your 2 post lift(please post pic)! Like other members here I will go ahead and do it with jack stands(no choice here anyway). Since you pointed out I have checked the weight capacity of my stands. Fronts are 3.5t and backs are 4000lbs each. Should I not trust them for this project? The reason for this set up is I trust pin type jack stand more than ratchet type especially in the heavier back side. I have a Sears aluminum ATV jack exact same as rsr91128 has. Minimum height of this jack may be about 2 inches.

Thanks for your comment. I think 40 inch is great to be safe. What I have read somewhere says that 37 inch works with the bumper still on the car. I have roughly measured the height from the bottom of the heat exchanger to the highest point of the motor. It's about 26 inches. So considering minimum height of the jack and wood blocks or a board on it, I guess I will need about 32 inches clearance total with the bumper off. Am I right?

Your fronts are 7,000 lbs each while the backs are only 4,000 lbs. I had the same jack stands and the thin supports are buckled. I junked them a long time ago. Use the same 3-ton or better a 6-ton JS for the back. Be safe.

bazar01 01-31-2011 03:44 AM

Here is a pic of the car on the Maxjax lift. I will start dropping the engine next weekend for the clutch while I have the axles out when I replaced the rear wheel bearings..

Thanks for the heads-up. I will consider getting another pair in addition to the the existing one.

Hey BW, I finally had the courage to do the engine drop. You had inspired me to do it. This is also my first 964 engine drop.
Tonight, after coming home from work, I started unplugging electrical connections on the left side of the engine. I had to remove the blower assembly to gain access to the rear bracket holding the connectors and fittings.
Tomorrow I will work on the right side of the engine. Hopefully by Sunday, the engine is ready to come down for the clutch job, power steering reseal and oil pressure sensor reseal.

Hey Bazar01,

That's great to hear that you have started as well. I adjusted the height up to 36 inches and drained oil yesterday. But I am kinda scared since I live very close to Hayward fault. I will remove the rear bumper either tonight or tomorrow. BTW, is your C2 Targa or Cab? It appears to be same color as mine which is Amazon green.

Hamptonsam 02-02-2011 12:32 AM

Any special tools needed
 
Other than jack stands and atv jack, are there any special wrenches or tools that are a must for dropping the engine. Or is there any special tools that if you had would make the job easier.

Thanks

Hey BW, if you can do it with jack stands, why can't I with a Maxjax?

I measured the engine height from the bottom of heat exchanger to the top and it is approximately 28 inches. If you can get 32 inches from floor to bottom of bumper, maybe you don't have to take out the bumper with your ATV jack set up. I am using a furniture dolly and will just raise the car. Technically speaking, it is not an engine drop, it's raising the car with the engine resting on the dolly on the ground. :D

Yes I have amazon green coupe.

Hamptonsam, I just went ahead and got started not knowing if I will need special tools. Maybe not. The only challenge i see is the oil fitting in the rear passenger wheel well. Maybe I will need a crows foot wrench or just two big crescent wrenches depending how tight there are. Other than that, I think it will be just regular wrenching tools.

bazar01 02-02-2011 02:39 AM

This is how I got started last night.

You can also remove the fan\alternator housing during the drop to gain a couple of more inches...

Hi Don, I looked at the engine compartment and checked it out. Actually the highest point is the top of the intake manifold where the throttle body is. When you take out the fan housing, you also have to take out the intake manifold to gain lots of top space.

Use a spare jack to support the transmission during the actual drop and put a piece of plywood on the ATV jack to help spread out the weight. The ATV jack will only go so far under the car while it's on jack stands because of the angle. Then when everything is dropped you can just roll it out of the way.

Right you are bazar01! I remember now, I loosened the fan housing to gain clearance while angling the engine back to the trans. I didn't remove the engine\trans together.

You can do it!

Bubbling well 02-04-2011 10:36 PM

Hey bazar01,
How are you doing?
I have removed the rear bumper and disconnected electrical on the left and top side. I will not post pix today because it is almost identical to your pix(Amazon Green C2).

Anyways, I have a question. There are two fuel connections to remove. One at the filter(supply) and others at the left(return). Hope it is not too late to ask but was I supposed to empty the gas tank? Wondering if I have to clamp fuel lines to minimize fuel leak.

Thanks,

BW

bazar01 02-05-2011 02:28 AM

Hey BW, I have not done much after draining the power steering and undoing the lines. Been working late at work, already to tired to work on the P.

I don't think you have to drain the gas tank. Just undo the left side return and right side at the filter supply line and you should be okay.

List of things to do.
I already have the half shafts removed during the bearing change.

1. Remove the a/c compressor and move to the side quarter panel.
2. Undo the big oil filter oil line fitting on the pass side. DONE
3. Undo the transmission shifter DONE
4. Unwire the starter and ground to chassis
5. Undo the second oil line hose on pass side DONE
6. undo the accelerator cable (debating whether at the pedal or at the engine)
7. remove HE hoses DONE
8. remove the slave cylinder from the bell housing and move out of the way
9. remove sway bar DONE

I guess that's it and should be ready to drop by undoing the transmission mount then the two rear engine mounts.

No. There was almost nothing coming out. Use some rag (through them outside after) and cap the line with a tape baggies. Do removed the fuel pump fuse/DME relay in case you reconnect the battery and turn the ignition on for some reason while the engine is still out.

Tha'ts what I thought.

I wonder why you would disconnect at the pedal and go through the trouble of pulling the long cable through the tunnel.:confused:

Is it easy to undo from the engine? I have not looked yet.

JJ 911SC 02-05-2011 04:32 AM

Easy enough... Its a press fit (pry off with a wide flat screwdriver).

About 18" from the tunnel wall.

Off to the 8 hrs in the garage saturday routine :D:):D

As you are on a lift, are you aware about the dropping angle for the "gear shift rod" to clear the tunnel?

I underestimated that when I did mind so it took a little longer than anticipated.

I am not sure what exactly you were referring to as the dropping angle for the gear shift rod.

I already had the shift rod disconnected from the transaxle. I moved the shifter to 3rd gear so it will be separated from the tranny. Is there anything else to worry about before I drop the engine? Let me know. Thanks.

Ok So you are just droping the engine not the engine & transmission as one unit?

bazar01 02-05-2011 04:53 PM

Sorry if I was not clear. I am dropping the engine and transmission together.

JJ 911SC 02-05-2011 05:04 PM

Isn't your "transmission rod" (disconnected from the shifter) still inside the tunnel or does it clear the tunnel as you will drop straight down?

bazar01 02-05-2011 05:16 PM

When I drop the engine and tranny, the tranny end shift rod will clear, so I don't see any obstruction. I should be good.

I guess that there is a difference between a 915 and a G50 configuration as mine was inside the tunnel before the drop.

Oh, that explains it. I thought you had done a 964 engine drop. Thanks for clarifying. I should be good to go then.
I plan to drop the engine next weekend though because the hydraulic table is not available until next Saturday.

Bubbling well 02-05-2011 06:33 PM

Almost there
 
Hey bazar01,
It's great to see your progress. I am being encouraged. Thank you!

I have disconnected the shift rod and sway bar this afternoon and will work on the slave cylinder later. A slight problem here, I cannot put enough torque on to the two 13mm nut on the slave so I have decided to disconnect the rubber hose fitting from the hard hydraulic line. It's now lubed with PB Blaster. Also removed the ground cable from starter but wondering if there is an individual ground strap from the tranny like a 914.
