Thread-Index: Ac7TIBb5b+SS13TEQEGVaBDlG9QQ4AAAzCUg References: From: "Bobby J. Hughes" To: "Rotary motors in aircraft" Charlie, Here's what I have for coolant flow. Water neck (that's what I call it) needs a plug to replace the thermoset. NPT tap and plug but don't remember the size. Drill a small hole (#30) in the thermostat plug to allow a path for air to migrate to the upper half of the water neck. Water out of engine\ top half of water neck, I have the radiator feed hose, water temperature sensor, -4 hose to a high spot on the swirl tank above the normal water level. I also have a Schrader valve for initial air purge, WP pressure sensor testing and radiator cap testing. I had 1/8 NPT fitting welded high on the top of the water neck for the -4 fitting and Schrader valve. The temperature sensor also required a fitting. There is a port for the factory water temperature sensor. My engine came with the sensor but I'm using it as a plug. I think others have calibrated the EM2/3 to use the stock sensor. For the lower half of the water neck\ water return to engine I have the radiator hose and a -10 hose from bottom of the swirl tank. The -10 is oversized but aids in filling up the system since I don't have a cap on the radiators.=20 My heater outlet port on the rear iron is plugged. Bruce T recommends not removing the factory press in fitting due to possible housing damage.=20 Oil out on the front iron and returned at the filter mount pad. The outlet is 18MM thread if I remember correctly. I use Dale's adapter block for the oil return and a remote oil filter adapter. I use -10 oil hose but others use -8. The adapter block has ports for the gearbox feed, oil temperature and oil pressure sensors. Some remote oil filter adapters provide two inlet and outlet ports. This offers another convenient place to added sensors. There is an oil sensor port in the housing below the filter pad. I don't remember the thread size but I recall it was different from the other engine fittings. Possible 1/8" British threads? =20 One of the oil paths below the filter pad may go directly to the pressure regulator but not sure.=20 Bobby -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] On Behalf Of Charlie England Sent: Sunday, October 27, 2013 9:22 AM To: Rotary motors in aircraft Subject: [FlyRotary] Renesis plumbing diagrams? I've got my intake manifold & heat exchangers mounted, & need to start 'plumbing' work. I thought I had saved flow path diagrams for the Renesis, but I can't seem to find them now. Anyone have oil & water diagrams they can share? The only info I've been able to find so far indicates that cooling water exits the block via the top water pump port & returns in the lower port, & the heater send port is the one next to the flywheel on the spark plug side. The small port at the top of the flywheel-end iron seems to have a matching port on the return side of the water pump fittings; is that an acceptable place to tie this line, or should it go straight to the swirl pot? Any options other than a big pipe tap to plug the inlet/outlet passage used by the thermostat? For oil, the Renesis images I've been able to find show an oil filter mount low on the accessory cover; not what I've got, and an oil port low in the flywheel-end iron, also not what I've got. Assuming that oil leaves the pump at the accessory case oil port, flows through the cooler, and then to the filter mount 'tower' that bolts to the top of the flywheel-end iron, what are the paths of the 2 ports in the mount point? (My engine came with the filter tower already removed & the mount point taped over.)
