Didn't comment before but it does look really cool!

Hi. Motor and Gearbox out. Need to send off the ZF and Mark wants to rebuild the motor at the shop.

Fairly big number attached to this exercise........

[William Abraham]

Just posted the motor on the 81 which is out while the car gets painted.

The 86 is still a labour. New suspension all in but for some reason the MIE front shock and spring set seems to sit very high? I have asked if this is an issue or if there is a fix for this. Seems strange though.

Various missing bits being sorted out. I will admit being a bit discouraged at the cost so far. Wish I could do more of the fiddling myself.

Ciao for now

Another picture of the 86

my guess is $20,000 US 5 for trans

Yes, I replaced them with a modified poly bushing from a 4wd supplier. I eliminated one of the reducer sleeves as the top and bottom have different diameter bolts... pretty simple really. Mine were collapsed and oblong reducing effective shock length by around 1.5 inches!

Would be interesting to see the photo of the rear of the engine noting the difference to the Automatic Trans Engine block. This engine block is supposed to be very different. Interesting cut outs on the trans bellhousing....

Hi I will arrange for some photos of the other side. I was unaware until recently that the motors are so different but only a manual motor will work on a manual car.

William,

this is normal. The stock springs/shocks are underrated and the car sags under the weight of the engine. The set from MIE is uprated and designed to avoid the problem, but at the price of making the car look a bit funny from the side. Mine does the same, and has the same set of springs and shocks.

Hi William,

I plan on changing my rear wheel bearings, mine are a bit on the loose side so I figured an ounce of prevention...

Do you know the part number or where to source these bearings? Are they f.x. identical to XJ6 cars, since they share (apparently) the same suspension?

Cheers,
Thor

Had I known they were different I would have taken a few pictures while we had the transmission out. I do have a few, but they're not really ideal to show the rear of the engine as a whole to compare.

Maybe the parts manual would have a diagram showing the difference?

I'm quite surprised that they bothered to make two different blocks for such a low production volume. I do know that they modified the bell housing pattern to fit with the Torqueflite.

Cheers,
Thor

I had described this in a technical post to ZF and their reply was: "Dear Sir,

I think the gear shift rail or the gear shift fork is broken. For maintenance und repairing please contact our sercvice station in GB"

However, contacting ZF got a negative response for assistance as "they don't service them any more".

Well the ZF is pictured out of the car but is off for repair. Wayne Lee has agreed to do this. He is from MST (Motorsport Transmissions) http://www.motorsporttransmissions.com/home

He specialises in the ZF S5 18/3 but has the manuals etc and has rebuilt the ZF S5 24/3.

He seems a reasonable chap on the phone and is doing some interesting work so we shall see. The other option was to ship it back to ZF but they were very uncommunicative. http://www.schiemenz.com/ Auto Schiemenz could work on the ZF but their email does not work, no one answers the phone that speaks English and I don't%2

For some reason I lost some text so here is the end of my post.

Another option was
P&W Engineering
Paley Workshop
Arden Press Way
Letchworth GC
Herts
SG6 1FR
UK
They could work on it and are Aston specialists. It seemed like money no object Aston restoration but they were uber professional and would be a perfect place to go.

I liked the sound of Wayne on the phone and his estimate is reasonable and the process painless so lets see how it works out. He also agreed to do a photo disassembly etc so I can post it which I liked.

Ciao for now

Thanks will keep you in mind as work moves forward.

[William Abraham]

Well the long awaited day has arrived. The amazing piece of ZF kit is at MST without a hitch and they have immediately begun to strip it down. Here are some pics to start. No analysis yet.

Ciao

[bundas]

if possible an engine side pic. of bell hsg. would be nice. The shift rail design is the same as a modern seven speed American truck transmission used in most medium size trucks.

What is the cure to the raised front end with the MIE kit? If you install the MIE rears will that level the car?
