A common problem with the JF015E RE0F11A variator  is an oil pump, due to the wear of the pressure reducing valve, the pressure drops, which leads to such symptoms as belt slips and slippage. The driver feels it as jerks and thumps when switching modes DRIVE / PARKING / REVERSE.

There are several solutions to the problem:

:1) Buying of used pump in good condition.

2) Installation of a new valve which is made in standard size. This type of repair is suitable if there is no wearout in the pump itself, the tightness will be restored.

3) Installing an oversized valve, Maktrans specialists ream the hole in the pump on the CNC milling machine to the size of the repair valve.

 Let`s consider the third option. We use exactly the milling machine and not the reamer because this method allows us to obtain a “cleaner” surface of the hole being machined.

Step one, the pump housing is fixed on the machine

Reamng The first pass of the cutter - roughing, the second - reaming a hole to the desired size.

Result

Vacuuming. The vacuum test should not show results below 14 inches of mercury, all above 20 is an excellent indicator.
