Back on this after some time on other things. On to the steering rack and the servotronic solenoid
This is a Jag XJ solenoid with a Bosch Junior Timer connector instead of the silly disintegrating wire that Audi claim is to make it possible to remove the rack
(which is bunk btw - this one works just fine)
I printed a polyurethane boot to cover it up, which is lined with waxoyl to stop any moisture getting in so this one won't corrode away like the last one did
Next I need to make a wiring harness - I may have shown this in the murple thread, but its here again for completeness. This is all that is left of the original:
Parts to make the Jag version work
Junior Timer terminals crimped on with red to red. Not sure if these solenoids are polarity sensitive but I'm keeping them the same anyway.
Assembled with the boot.
Terminals on the other end. The cable is 85cm by the way.
Red to red again
Completed adapter harness
Which fits like this
This will probably outlast being allowed to burn dinosaur squeezings
Back on to cleaning the engine bay. The fan resistor pack is looking a bit sad with all the studs snapped off
Got in a grump with cleaning so moved on to the brakes. The fluid is a bit grim, as always. No one ever changes it
Old brake fluid vs new
There was a very good reason for changing the brake fluid
before I then took the braking system apart, but I forget what it was
The OSF hard line had been ruined by the PS fluid eating the plastic coating allowing it to rust away so this has to come out
Something has dissolved the rubber in the brake pipe clip - probably the copious amount of PS fluid which was coating everything
Old brake pipe off
Removed the clip and cleaned all the yellow nastiness off with thinners
Looking much nicer
OSF brake pipe refitted and a replacement clip in place.
I'll finish cleaning the bay tomorrow and then I can put the rack back in
