First engine drop questions

theclaw · 08-19-2013, 06:17 PM

I'm having to do some work on the clutch and so down comes the engine. I made some good progress today, snapping pictures so i don't forget what goes where and tagging everything. However, I got a little stumped when the Bently manual says to

-Disconnect wires for speedometer sender. Push through bulkhead.

I'm not sure what wires they are referring to. There are two set of wires and two connectors in the coupler access area. One doesn't even loo like a connector that you can snap off and on.

Any suggestions? Once I figure that out, how do you push them thru the bulk head. Sounds like pushing a rope to me.

Thanks,

The one closer to your wrist is the speedo. The hole in the tunnel is big enough to pass it through.

Thanks K, which side pulls out the Green/Brown or Brown-Red/Brown?

the 2 brown/red wires run to the speedo sender.

Why not just slide the sender "puck" out of the side of the trans and tape it out of the way. Heck of a lot less trouble!

+1 ^^^

I do that at the transmission side. Take out the sensor pug and hang it off to the side

+2, just remove sensor at gear box, leave those wires alone.

Removing the puck is easy too. Just have to be careful of the attachment on the top of the tranny. It's an attached zip tie. That cable is $100 to replace. In hindsight I would have pulled the puck end and then pulled the loose wire through where your hand is to protect it.

Might catch up to you tonight. Car is on the hoist, PB Blaster has been liberally distributed. Tea bags stocked.

So you are removing the trans and engine together then? I'm still debating. I seem to have a crank seal oil leak. I'm a little concerned that if I remove the trans it might end up with an LSD in it!

If you look closely, there are just simple male/female spade connectors inside the weird German plastic protector. Just reach in there with a pair of needle nose pliers so you don't pull the wire itself off the spade connector.

I prefer to leave the speedo sender on the trans. Not hard at all to push out the wires since there is a grommet surrounding them. You can see it on the vertical wall of the tub. Since you're already into the access cover to disconnect the trans/shifter coupler, I figure it's no big deal to unplug from there.

Also shove the shift rod boot into the engine bay. You have to "unfold" it a bit to release it from the tube in the tub. The boot is easier to be remove at the tub, not at the trans. It's more of a press/push fit on the trans vs. the unfolding routine at the tub.

Ok, backing up the bus a bit. I'm posting some more pics as requested and will likely have some questions as I go along.

I'm basically following the Bentley guide with a cross reference to Wayne's most excellent 101 Projects book.

Im lucky,i have a mid rise lift. its going to make this alot easier. One of the things I first noticed was that the cross member on the lift interfered with the tranny.

So I rolled the car a little further backwards on the lift but I wasn't comfortable with the balance of the whole thing. Normally it is rock solid. With the car moved to the back of the lift you could tell it was a bit off balance. So, I going to leave it here but when it comes time to actually do the drop,I'll reposition the car on the lift so it clears.

I did splurge and picked up a couple of Griot's fender protectors.

The first few steps in Bentley I could skip because upi had already taken the AC compressor out.

Disconnected the battery

Removed the air filter cover, disconnected the breather hoses and vacuum lines on the right side of the engine.

Didn't have to remove the cruise (already gone) or large heater elbow and blower since I did a backdate last winter. I did have to remove the cover of on the coil and take off the secondary wire. Also disconnected the fuel lines and the 14 pin harness off the left side electrical panel.

Disconnected the harness connectors on the left side of the engine. Marked everything with yellow tape.

theclaw · 08-21-2013, 06:18 PM

Disconnected the harness from the right side.

I finally got around to disconnecting the speedo sender wires but I'm still not sure how that connector is going to get thru the bulkhead.

Along the way I made a stool low enough that I could roll around under the mid rise. The blocks were already around because I use the to support the car sometimes. The roller was found under the porch of a house I owned 15 years ago. Never throw anything away.

While I was rolling around underneath tonight I disconnected the throttle linkage and heater pipes from the exchangers to the flapper boxes.

theclaw · 08-21-2013, 06:29 PM

I noticed that the rag I had stuffed into the oil pipe was soaked and had dripped enough to create a decent sized spill. So I took the rag out and stuffed a glove in there and rapped it up with some tape. Except by now, most of the oil that would drip out was probably on the floor.

Since I was dripping crap all over the floor I started soaking the axle bolts with ATF/Acetone solution.

Got another question. Why does the book say to takeoff the coil helper spring and the clutch release lever. Seem to me, once you get the cable disconnected there's nothing left attached to the car.

theclaw · 08-21-2013, 06:34 PM

Picture for post above......

theclaw · 08-21-2013, 06:40 PM

Along the way, took out the passenger seat to make working on the shift tunnel that much easier.

Still have to disconnect the shift rod from the coupler.

Yeah, trying not to get too caught up in the, "Gee, what can I do now!" If I get this done quick enough I can make it to Octoberfest at Blackhawk. Given my schedule though, this might stretch into the winter. If that's the case, all bets are off!
