7ch. - channel drive rolling cone driven shaft, the pressure comes from the oil pump and
can reach up to 60 kg/cm². Therefore, we increased the requirements for sealants.
Seals are at the entrance to the oil flow in the lid of the driven shaft and outlet
covers the transition on the hollow portion of the driven shaft.
Compressed air, if there are no problems with seals that pressure must be kept and
singing no air should be. If you hear the faint hiss of air as possible on the mobile
part cone and shaft. This is offset by performance oil pump.
8ch. - channel drive rolling cone drive shaft, oil pressure comes from the valve "VARIABLE
9,10ch. - places to connect the oil cooler hoses.
11 - tube to test line pressure oil pump.
Cover variator (block solenoids) temporarily put in place fasten it on two bolts on the
diagonal. On the upside, we were only bolts pillows variator, it is also the holder and for the
Check the status of the transmission oil drained from the variator.
Such a test can bring a lot of information. Now we can drain the oil from the variator. We
choose the bucket at least 7 l, unscrew the plug (sleeve). Oil drained from 5 to 6 l, at a rate
of up 8.5 liters. The rest remains in the HT,in the cavities of driving and driven shafts.
Bubbles and churning oil say or improperly adjusted level, or air leak from the oil pump
variator. Inspect rain in the bucket, the presence of particles of the friction material, plastic or
shiny sawdust indicates a serious problem. If iron filings are attracted to a magnet can be HT
or damaged drive gears. If the sediment is hardened crumb sealer, they can clog the channels
in the hydraulic valve block. After the final dismantling pick the oil filter to see which products
of wear deposited in it.
Dark oil with burnt smell indicates that there is a problem in the variator. On a white paper
napkin drip oil. The oil will soak into the paper, leaving a stain on it. On this spot you can
identify some of the problems of the variator.
- Scorched oil, blackish stain particles from the friction material. Usually this indicates an
increased wear of the friction.
- Embedded in a tissue oil reserves on its metallic inclusions - a sure sign of wear metallic
parts in box and in HT.
