My first engine drop. Objective is a new clutch, rear main seal, new sound pad, and who knows while it is out.

Lots of DIYs on engine drops, manual, & Adrian book cover it well. Also having renlister John Mc throw in some tips. 8 hours in total, plus lunch

The only part I was confused on was removing the accelerator cable. I know some do it from the engine, but I ended up doing from behind the pedal board. Not well documented. See pic. Also removing the interaxle differential lock took a while to figure out - pulling out the lock key is weird. Otherwise it is follow the instructions.



Cable behind the pedal board.

The scissor table made the drop very easy. And a lift. I can’t imagine doing this with jacks only!!

Nice work spokes! Where did you get the protective cover on the rear of the car?

Spokes

Thanks Dingo. I sourced it off eBay https://www.ebay.com/itm/Porsche-rea...-/141032538366 it works well.

And split.

The clutch disc (Rubber Centered) looks like it is NLA (see pic). Anyone else updated a ‘89 C4 clutch to later parts? Any other issues?

964Andrew

I have the newer clutch disc and pressure plate mated to 89 single mass flywheel. No issues.

Got this on wholesaler closeout 4 years ago for cheap, still available BTW.

Don't forget about the Clutch control shaft needle bearing bits and bushes.

Thanks!

Thanks Andrew did you fit a new starter ring to the pressure plate? Assuming your fly wheel only has the single tooth ring.

While you are doing this job, it would be a good idea to take the nose off the transaxle and pull the planetary gear and have the pins welded in place. It's not a hard job, and will save you huge money if your pins were to otherwise work themselves loose over time...which causes a big problem.

Don't want to derail you. Looking forward to seeing more of the clutch job...

Spokes

Cheers Goughary, ha,ha, the list grows. The car is off the road now through to the end of winter. So over the next 4 months the goal is to get a list of reasonable jobs done.

Goughary

Uh oh. Lists are dangerous. When i pulled my motor for the top end rebuild...it wasn't until much later, that i realized the bulk of my cost wasn't the top end rebuild...lol.

That said, i didn't know back then about the planetary gear issue. And really wish i had that done, just for peace of mind.

964Andrew

I have swapped the old ring to the new plate.

Thanks!
Andrew

Spokes

Great, most likely I will do the same. A few taps with a drift I hear will remove it.

Spokes

Few taps with a drift and the starter ring comes free...
