MCX Nytro https://www.fourstrokesolutions.com/apps/photos/ MCX Nytro Roll-over Valve installed on a MCX Turbo Nytro Note: There are two options for valve mounting locations on the MCX Nytro. The desired location is between the oil tank and the MCX aluminum Tee as shown on Summitseeker's sled. It is a fairly tight fit, since the MCX Tee is using some of the space allowed for the roll-over valve. The advantage to this location is that it helps prevent oil from leaking into the MCX surge tank during a roll over event. The valve is mounted with the "short fitting" facing the oil tank. (Same as a stock sled) If space is to tight at the prefered location, the valve can also be installed in the long vent hose that exits out of the top of the MCX surge tank. At this location, oil could still leak into the surge tank, however it will still be closed off from leaking out of the long vent hose on to the snow. The oil will drain back out of the surge tank, into the oil tank once the snowmobile is back up right. When installing the valve in the long hose that exits from the top of the MCX surge tank, the valve is mounted so that the "short fitting" faces the surge tank. With either location, position the valve so the solenoid end of the valve is facing upwards approx 45 degrees. This helps oil vapor drain out of the valve, for a fast responce time. https://www.fourstrokesolutions.com/apps/photos/photo?photoID=71678136 71678136 Roll-over valve installed between the MCX tee and the oil tank Thanks to Summitseeker for the photo! https://www.fourstrokesolutions.com/apps/photos/photo?photoID=71678137 71678137 MCX Nytro before a Roll-Over Valve Kit is installed This view shows the MCX aluminum Tee and long vent hose that exits the MCX surge tank.Note: There are two options for valve mounting locations on the MCX Nytro.

Position the valve so the "short fitting" faces up towards the MCX surge tank. https://www.fourstrokesolutions.com/apps/photos/photo?photoID=106292548 106292548 Latter sytle MCX air/oil separator tank This view shows the valve location on 2nd design MCX air/oil separator tank (circled in Green). In this case the valve is installed in the outlet hose of the MCX tank which is part of the inter-cooler. IMPORTANT, the valve must be installed so that the "short fiiting" connects to the tank and the "longer fitting" attaches to the outlet hose that runs downwards along the oil tank.. https://www.fourstrokesolutions.com/apps/photos/photo?photoID=188494178 188494178
