I removed the block complete in it's housing...removed air pump and started to undo valve block from plastic housing...

Undo the blue hose from valve block...

Working side....

Undo solenoid covers from valves....

WP_20170622_00_39_03_Pro.jpg


Meant to say, one job was to check the dessicant ....

If it was damp, wet or powdery it's time for a change...this is perfect :)

Next job, remove valve block from plastic housing and lay on clean work surface...undo drive control pack & note which way the brackets go...

Below is the other bracket, photo taken to recall which way round it goes...

WP_20170622_15_25_16_Pro.jpg


Ok, covers off...

WP_20170622_15_27_33_Pro.jpg


I decided to mark each solenoid cover so I could replace them in the right order...imagine the fun if you mixed them up :p

WP_20170622_15_35_20_Pro.jpg


Off.....next....

WP_20170622_15_37_28_Pro.jpg


Naked!

WP_20170622_15_37_34_Pro.jpg


Then I removed the valves and was left with some "O" rings...remove these and wipe the block with a clean soft cloth. I used a dry tea towel.

WP_20170622_15_52_03_Pro.jpg


I then vacuumed any dust with the tea towel over the nozzle to prevent damage

WP_20170622_16_07_51_Pro.jpg


X8r's very comprehensive "O" ring set

WP_20170622_16_09_42_Pro.jpg


Didn't lose the spring...diaphragm was well jammed in though

WP_20170622_16_13_56_Pro.jpg


Removed the collets so I could replace the airline "O" rings

WP_20170622_16_16_45_Pro.jpg


This is a very handy tool and got them all out, even the tiny wee ones...

WP_20170622_16_23_30_Pro.jpg


Turns out it's a Mercedes tool (it came with my E320 couple of year ago) and the part number is there for all to see...

WP_20170622_16_28_38_Pro.jpg


Just the job...

WP_20170622_16_28_53_Pro.jpg


WP_20170622_16_24_38_Pro.jpg


Next, I laid out the new "O" rings for insertion into the airline holes...

WP_20170622_16_27_18_Pro.jpg


I painted each new "O" ring with vaseline to aid insertion and prevent nipping...

WP_20170622_16_31_16_Pro.jpg


They are "mounted" on a drill bit 1/2 mm smaller than the "O" ring...

WP_20170622_16_32_08_Pro.jpg


I inserted each "O" ring with my fingers, then pushed it home using the end of the drill bit (the blunt end), then poked the bit in (after a smear of Vaseline) and twisted it to ensure the "O" rings were centred...

WP_20170622_16_35_27_Pro.jpg


I re-inserted the collets again...

WP_20170622_16_35_46_Pro.jpg


Here's a photo for L322 to give him a buzz :D:p

WP_20170622_16_37_17_Pro.jpg


As each set of "O" rings went in, I checked they were centred

WP_20170622_16_41_37_Pro.jpg


Valve block next

WP_20170622_16_56_23_Pro.jpg


The teeny weeny "O" rings were a mare, ended up using a thin bladed knife to get them off over the end of the valve....

A smidge of Vaseline...

WP_20170622_17_01_13_Pro.jpg


WP_20170622_17_07_00_Pro.jpg


When screwing everything back together, I screwed them in a couple of turns, then used the drill. I set it to screw and adjusted the torque, more so I wouldn't snap my wrist :p

WP_20170622_18_12_57_Pro.jpg


Don't forget these little boogers...:eek: Undo the phillips screws, remove the top and twist the cap until it comes off. Watch for springs. I painted a bit of Vaseline on the bottom, slid the "O" ring down and gently pushed it back in place, slid the top cover on and screwed it up hand tight...

WP_20170622_18_34_31_Pro.jpg


Rebuild time... Anyone notice the cock up?? ;)
WP_20170622_19_03_09_Pro.jpg


Above, I put the solenoid covers on 180 degree's out. Made for a bit of fun trying to place the wires, but I soon figured it out. Wife came home and wanted her kitchen back. She was hurrying me, but ended up waiting longer while I undid all the screws and fixed my cock up :rolleyes:

Thread lock just stops everything shaking loose

WP_20170622_19_12_10_Pro.jpg


All that's missing is the motor... It's easier to replace it when the valve block is bolted back on the car.

So that was my attempt and tomorrow I'll find out if I was successful :confused:
 
My wife is always going on about my nutrient reference values an all :rolleyes:

Plenty nutrients in Scotch :D

I replaced the diaphragm as I found the old one, almost shiny side up. The plastic bit located in the middle of the diaphragm was a mare to get off and I put a small gouge in it, but not where it makes contact with anything else. So a bit of rubbing down with sandy paper took the sharp edge off it.

Apart from that and getting the solenoids front to back, it went well. :)

Still no idea if it works :D

Don't want to appear rude and jump in here as some random stalker but very impressed with this little rebuild...but a bit concerned that your tub of Vaseline is so small, what with you living in such a remote place(as far as postalservices are concerned)....you need a bigger tub!!
