                                                             PREPARATION

 

   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

            RATIO CONTROL".

   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

engine.

 

               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.
