Does that co screw on Afm affect to mixture when ecu is in closed loop? Im tihinking that Afm flap doesnt open that much when theres no load enough. Ie mot testing. Could it give unmetered air? Do you understad what i mean?
ok. Doesnt this run rich now? Shouldnt it be lean if intake side leaks? I may not undestand this too well though.
Haha. Original speedlines got sandblasted… Now these rares are getting chrome powdercoat on. I might made a mistake, but those were in bad shape. Sorry no pictures.
Argh it happened again part 2.
My Folkswagon didnt pass MOT. Emissions to high…. I wonder i got it through last time with broken ecu and now i have this working pb ecu. 6000 km driven since last mot. Now it was from CO% 1,05 at +2000 rpm when limit is 0,30. HC 61, CO2 14.00, O2 0,50. So does my pb have asthma?Does that co screw apply at this rev range?
Nothing new on VC rebuild. I havent the time for it now. But i have found source for new x rings to VC. These are made from PU to the exactly same size as originally. But i come to that later.
Ok. I cleaned all the plates today.
I used heavyduty grease remover and it worked good. I think i now know what is this wearing on plates
( that darker area is what i thik is wearing)
I bought new o ring for that cover/ cap. 122mm*3mm. If Fits nice and makes it tight. I also bought new oli seal for visco housing, it was not in vw dealers listing anymore as it is dropped now. Size is 40*52*6, i bought new one 40*52*7 and it Fits good and that contact with axle is now at different spot related to 6mm oil seal so it should be only good thing. What is hard, is to find new x rings for visco, i found ones but those were made of nitrile as originally they are polyurethane( something to do with wearing i think). Maybe PU o ring would work also.This is what made me to start this project, and that i have one vc and diff as spare. That vc is i question becouse it have to be machined as those mounting lugs and inserts are so badly damaged.
Plates inside vc look allright i think. That texture/ perforation ( maybe wrong word) is still there. But i dont know how unused should look , im just quesing. There were light rust also on that top plate. But this vc had a leak from broken lug/insert.
I have a source for vc fluid here.
After new threads and inserts i have to fill it with something and close it once to make one pressure test for the casing. That sae documet says something about 100bar but i dont have anything to produce pressure that high. I fi fill it with water and pressure it with lets say 10-20 Bar it should be fine… Maybe.
Today i began to clean up plates and visco itself. I need to find right cleaning solvent. I tried Ethanol and it didnt do much and then i tried motorwash, it is somekind of petroleum or so. Dont know the right word for that stuff. I worked somehow but im not statisfied with it. I think i will try that detergent which is used to remove silicone from bathrooms,sinks, ect. After all this visco stuff is silicone.
After that i have get that visco housing machined. Those three threads and inserts are damaged so bad,( pictures are in my country 1991 thread). And i need new inserts and lock rings also.
Hah again. I just should stop asking things before I even have tried my self.
Ok I got my VC open, I needed a bit of leverage, I had 50cm extra length plus 40cm of socket wrench, Socket needed for this job is 55mm, Rust off is nice add to job also, it helps that metal wire thingy to move more easy.
Few pictures
You need to help that wire end out from that elliptic hole outer side of vc and you get the clue which way to rotate the cap to get that wire out.
Then you only need to give some leverage and that wire comes out.
Next thing you have to do is punch to the axle from the other end to get that cap off.
Ha. Shouldn ask before even trying… It was easy.
Only needed loosen that centering nut/cap/ dont know the right word. But it wasnt very tight.Is it worth of trying to open visco with 55mm wrench tool? Or should i use that lathe technique as in vwvortex Forum they do. Will that visco hold that 100bar pressure if cover is locked with snapspring…
Thank you again Chris you have lots of knowledge on these. IM fine, i think i can buy these parts from Here. But if i wont il contact you.
