I use an ultrasonic cleaner and put the whole assembly but after seeing this...I'll break one down to see if it's effective! Thanks for the awesome video!
Often it's the locking pin that gets stuck and make them rattle at a cold start. It's more rare for oil to leak between both sides, but often also has different behavior but easy to see with a scan tool you then say the actual timing jumping all over the place compared to the commanded timing.
I was surprised that we had one faulty one. I’m going to tear it apart and try to figure out where it’s failing. The pin on the VW variator was obviously worn, but these didn’t seem have any signs of wear just sludging. I just did another timing job where the plastic guide on top of the spring was worn down to just about nothing.
I think the failure on these after cleaning has to do with how easily the parts move around during reassembly. Even with them sitting on the camshaft in a vertical position it was difficult for me to feel confident the plates where centered properly. I couldn't find torque specs for the 6 bolts either.
I could not find the torque spec for those bolts. I don’t think want us pulling them apart. I just paid attention to how tight it was to remove and tried my best to match it. Thanks for watching!
@@mountainviewsgarage Didn't have any luck with Alldata and their resources either. Used a torque wrench to break them down. Most averaged about 225 in lbs before breaking loose and ranged from 204 to 243; one variator though ranged from 170 - 220. Trying to account for kinetic vs static friction, and the fact that they'd been there awhile, I torqued them to 185. Made sure centers moved before putting them in the locked position. Hopefully it works out.
@@mountainviewsgarage In case anyone is using my torque figures, it didn't work. Screws backed out after 20 minutes pushing the reluctor plates into the cam sensors.

Glad it was helpful!
Idk why people say to replace those variators. I’ve opened and cleaned many of those, and have never seen anything that looks like wear.

Great video! Do you have a torque spec for the 6 bolts that hold each variator assembly together?

Yeah I don’t think they wanted us to take them apart. But sounds like you got it done. Good luck with your project!
