You can get a retaining nut from Toyota that screws onto the thread and holds the spring down, it's about £2.

part number 09756-00010

I did it in the past on MGF calipers (equally as bad), and it was a good amount of messing getting the spring compressed and the circlip on! Toyota nut took 10 seconds after fitted. :)

That cheap , I din't know that .
Din't even know it was available .
Lucky I didn't start machining the nut :)

Now that I have reluctantyly decided that an engine upgrade will not be done , I'm thinking of retrofitting an airco to my MK1 .
Can it be done without to much trouble .
Guess I'll have to drop the fuel tank , but I have a lot of experiance
doing that .
I've also worked on AC 's before , I have a vacuum pump and a set of gauges and stuiff like that .

Anyone have one for sale , or pictures that can show me what I'm up against .

I think there was an AC pump on ebay not long ago, it may still be there!
At least the 4AGE has the two belt pulley there for it.

The hardest parts to find , iI think , will be the parts underneath the dash .
vaporisor , air duct's and all the plumbing .
And I need them for a left hand drive .

Couple of pictures of the car being towed to be resprayed .

No body filler has been applied yet . As you can see , even without any filler the rear arches look quite good .
The white stuff is an epoxy primer .

The mr2 is being towed with a triangle bolted to the front bumper mounting holes . It was fun watching the steering wheel move in my rearview mirror . It towed very well , better then I expected .

Image

Image

All other parts , lids , doors , bumpers , the list seems to be endless with an mr2 , are already resprayed . It's been a long time since I've handled a spraygun . The front hood has a small runner in it . Barely visible , but an imperfection none the less .

Nice work, 're the aircon, the loom is already wired to run aircon as standard.

Are you sure about that ?
I've had the car virtually stripped of everything , but didn't come across any not needed wiring .
Maybe it wasn't present on the earlier versions ?

Picture of the now painted rear arches .

Serviced the engine today , t-belt , oil , spark plugs ....
Yesterday I swapped the old C50 transaxle for a freshly build c52-c60 hybrid . Big thanks to paul woods for putting all the info on the net .

so It's mainly some details left .
Driveshafts , bleeding the brakes ... couple of day's and it should be running .

Oh and btw , I hit a small snag .
My car is a 1986 MK1 .
The front spoiler is rusted , I think beyond repair .

So I got me a 2 piece MK2 lower front , thinking it would simply bolt on .

Well that is not true .
The MK1b is quite different in that area. :(
The crossmember on wich the radiator rests is different , and welded to the body at a different angle .

So I have some adapting and fabricating to do to .
To bad , didn't count on that .

But as all the parts are already painted , there's no turning back .
I'll adapt and gett hem on somehow :)

Here are a couple of pictures how I fixed the sagging doors .

Started by removing the old hinges with an angle grinder .
Didn't want to touch the part that is bolted to the body , as it still is nicely sealed .
The hinge pin in pressed and rivetted , si I just ground it away completely .
Image

The moving part was bored and reamed to a bigger size .
Image

Image

Phosfor bronze bushings , interference fit pressed in and reamed to size .
Bushings have a larger contact area then the originals , so should last a little longer , I hope

Image

The entire assembly was trimmed to the right length on the lathe .

Image

And a new hinge pin completes the job .
In an ideal world , this pin would be heat treated and ground to size .
Don't have that equippement , so I used a good quality bolt as a blank , and polished the pin .

Image


The result is a rock solid door that has no play whatsoever , and hopefully will last longer then the original .
Image

4 hinges took almost a full day's work , but it's well worth the effort .
