Having just read one of my Christmas pressies from the wife, I'd say there was more chance of me going into space than fitting a V8 into an Esprit.................or anything, come to think of it.

Right, the winter 2017 refurb thread is now open for business. First up, gearbox removal. Despite having taken good care, the new rear crank seal I fitted started to leak. In fact it leaked more

Finally been allowed out, and managed to cobble together a brace for the engine to sit on while the gearbox is out. Bit of angle iron, with another couple of bits of herring gull shit-welded onto the ends, some rubber insertion stuck on the surfaces to cushion the sump and chassis members, and it works a treat. I can now raise or lower the scissor lift, or move it in and out of the garage.

Chuffed.

Meanwhile, by picking it up, shaking it and thumping it, I've managed to extract half a tonne of old shite that's been rattling around in the tailgate presumably from when it the car was first built. Rusty washers (flat, and spring variety), God know how many lumps of old GRP resin bonding, and two large bits of rotten steel that must have been 3" x 1" which necessitated yet another hole to be drilled in order to remove them. Given the amount of rubbish, either some bits are going to fall off while I'm driving along, or someone was having a laugh at the factory. I also decided to replace the screws holding on the tailgate louvres, as they looked in poor condition. It's fair to say that was a mistake, but as I've done one, I suppose I'd better man-up, and do the remaining one, too.

Looks good, but are the bolts of the sealhousing not supposed to be "buttonhead" bolts in order to avoid clearing issues with the flywheel?

Here's my solution to the engine support issue. Inspired by a tool made by Stan, a former Lotus/Lambo tech. Adjustable up and down, it makes transaxle installation much easier. There is a large pad on a swivel on the other end of the centre threaded adjuster that supports the sump.

Having replaced the hateful rear crank seal yesterday, I started on the clutch job, with Shan holding the pry bar to lock the flywheel. I’ve blagged an old input shaft to use as the alignment tool from Chris Cole, which means Sparky can now have his one back (cheers, mate!). After 5,000 miles, the clutch is still in excellent condition, with no evidence of chatter, or slipping. This is the PNM uprated S4 unit with the flywheel redrilled to accept the S4 pressure plate.

There’s various bits needing to be bolted onto the gearbox and the release fork fitted, then we’ll see if we can get it in the car without dropping it.

Not all of us are blessed with your astonishing talents for doing jobs in half the time!

No speedo drive on the S4s, there’s a speed sensor on one of the rear hubs (RH I think).

Sort of Ian, the rear right ABS sensor is tapped off to the ECM which drives the speedo, same as the V8.

I tempted fate...now my Esprit V8 IS in bits...(sob)

I definitely have two separate sensors on my car. I thought one was ABS, the other a speed sensor. Maybe the V8’s are different?

Anyway, gearbox insertion was postponed due to broken roll pins, and no spares, so I’ve got to order some.

Apologies Ian, you are absolutely right about the VSS. On the S4s it drives the speedo directly as there in no provision on the Delco ECM. The V8 ECM does however, hence the VSS being deleted and the ABS tap off.

And that sensor even on cable driven cars definitely affects and adjusts the fueling.

And that's with an input shaft?  Get on with it, FFS.

And with the wife getting down and dirty, too.  But to be fair, I am still suffering from the after effects of man-flu.

Pshaw.  Get in there, straddle her, arms underneath and give it one big heave.  Always works for me.
