Vibration (CVT)

Post by Tero Huikko » 12 Sep 2009 07:39 am

This came up...

If I drive normally there is strong vibration that disappears if I accelerate hard or if I release the throttle at full speed...
Belts?

belt tension

to solve that you need to get the secundary gearbox to the back

Yup...this was it. 2mm backwards and after that the disc gap was 1.8mm.
Thanks. 10 minutes job.

Still vibration when I take off when the car is cold. Disappears after few miles.
I don't dare to tighten the belts any more than I did.

Belt changing time?

could be if the belts look a bit busted;

i suggest you also try the ATF trick:

50cc of ATF oil injected with a syringe in the 2 rubber membrames at the pulley shafts of the secundary gearbox.
and 100cc of ATF oil behind each menbrane of the primary gearbox

This is new to me...ATF injected to the pulley discs? What should be gained by doing this?

See the green book, for example... Page 19, Operation A6. Under problem solving for vibrations, actually. "This applies only to vibrations occurring with a cold CVT up to chassis no. 322553."

The CVT primary has 0.55l of ATF inside the gear case, and 0.1l of ATF inside each sliding pulley half.
The CVT secondary has 1.0l of ATF inside the gear case, and 0.075l lf ATF inside each sliding pulley half.

The gear case oil is specified as Hypoid oil SAE 80 or SAE 80W/90 in accordance with specification API GL-4 or API GL-5 (MIL-L2105 B or C) Nordic countries: ATF, type A/A or F or Dextron. The sliding pulley halves only take ATF.

OK, this might be worth a try. Thanks. I'll have to check the book.

I read the entire book and not a word on this subject. I can't understand where to stick the needle...

Umm... First of all, use just the syringe, not the needle - you're not supposed to stick a needle through the diaphragm. (eli tosiaan pelkkä ruiskuosa, tarkoitus on vain saada määrä mitattua, eikä piikittää mitään/ketään) <-- Finnish explanation, in case anyone was wondering.

Then the green book. The PDF version currently on V3M (v3m_technical_CVT.pdf) has it on page 20/85 of the file (page 19 in the original scanned book). It refers to operations H22-H23 and H26, which are on page 80/85 of the file (page 79 in the book). Though I wonder what part of the long list of preliminary operations is actually needed for just changing the oil. I haven't changed it in mine so I don't know.

you don't have to change this ATF oil, all you have to do is fill it up.

this oil is in the primary the lubricant for the centrifugal weights and sliding of the pulley
and in the secundary the lubricant for the sliding of the pulley

easyest is the secundary gearbox, you do stick a suringe + needle in the rubber seal and fill it up with 50cc of ATF, the small hole doesn't cause any leaks. don't use a supersized suringe though.

with the primary gearbox there is a trick for getting the oil behind the menbrane without removing any parts.
you prefill a cup with 100cc atf. you attach a rubber hose to one of the 2 pipes at the primary pulley, you suck or blow on one and then before you release it you put the hose on the other connection in the cup with the atf and let the pressure/vacuum inside the gearbxox that you've just build up suck the oil inside. if you're a bit lazy a running engine and playing with the mountain-kickdown switch can help you doing this :lol:

from the piece above i don't know out of my head in wich pipe you have to suck of blow, i've had a hard week... will come back to that later

Are you sure that this suck&blow method will result the ATF in the right place?

This is the secondary unit. Did you mean injecting with syringe thru the inner rubber?
