(35.6 cm) Electric Fan · Fan Controller · Internal 60 PSI Cold Oil By-Pass Check Valve · Temp Sensor · Wire Harness · Inlet And Outlet Ports · Slide Out Screen · Removable Top Refer to pages 24 through 30 for a complete parts listing. Mounting the Oil Cooler Choosing a Location for the Oil Cooler The skid steer roof is a prime location for the oil cooler. Cool, clean air is available and the cooler is not blocking the operator's line of sight. It will add approximately 13 in. (33.0 cm), plus the height of the mount, to the height of the machine. This could be an issue if low clearance is needed. Behind the operator's cab or on top of a forestry package are also places to consider. IMPORTANT - DO NOT: · block any operator emergency escape routes. · block access to any machine service areas. · interfere with operation of the boom arms. · severely limit the operator's vision when choosing a location for the oil cooler. The first step is to determine the best location to physically mount the oil cooler. The cleanest, coolest air available will deliver the best oil cooling results. The oil cooler draws air in from the bottom and blows it out the top. The oil cooler is approximately 46-1/2 in. long x 25-5/8 in. wide x 12-3/8 in. tall (118.1 cm x 65.1 cm x 31.4 cm) and weighs approximately 253 lbs. (115 kg). See "Dimensional Drawings" on page 33 for dimensions and specifications. When positioning the oil cooler, keep in mind that the bottom screen slides forward. Allow clearance when choosing a location for the oil cooler. Universal Hydraulic Oil Cooler OM 13 Set-up Instructions Mounting the Oil Cooler (Cont'd) Designing a Mounting Bracket Because there are many skid steer brands and designs, you will need to use some ingenuity to design brackets or some form of secure hold-down device. IMPORTANT: When designing your brackets avoid drilling holes into or welding onto the roof or cab structure. This could weaken the cab rollover and falling object protection. Drilling holes could also cause water leaks into the cab. Welding directly onto the cab may make the mount removal difficult. Look for holes, tabs and lugs already on the structure which could be used as mounting points. If drilling holes can not be avoided, look for tabs, lugs and overhangs which can be modified without affecting the main cab structure. Checking Loader Arm Clearance Connecting the Hydraulics Connect the Loftness Universal Oil Cooler behind the original oil cooler so the hot oil will enter the original oil cooler first and the Loftness Universal Oil Cooler second. This will give the best cooling results for the entire hydraulic system. Use the schematic on page 15 as a guide when installing your Loftness Universal Oil Cooler. Pressure Relief Check Valve The Loftness Universal Oil Cooler has a pressure relief check valve built in to allow the oil to bypass the cooler if the pressure builds beyond 65 psi. Raise loader arms slowly and check clearances for cab, cooler and mount. Lower arms and adjust mounting if necessary. Recheck clearances after making adjustments. NOTE: If the cab tilts for service, make sure this is still possible with the cooler attached. With arms lowered, tighten all mounting hardware to the proper specifications. 14 Universal Hydraulic Oil Cooler OM Loftness Cooler Position Schematic Set-up Instructions Universal Hydraulic Oil Cooler OM 15 Set-up Instructions Loftness Cooler Position Schematic (Wire Harness N68127) 16 Universal Hydraulic Oil Cooler OM Fan Control Box Configuration Set-up Instructions Fan #2 40A Fuse Fan #1 40A Fuse Relay 35A Fan #1 01 01 30 30 85 30 87 86 85 30 87 87 30 31 15 87 Relay 35A Fan #2 (Viewed from bottom) Timed Delay Relay 01 12V Battery 15 12V Key Power 30 RED 12V Power 30 BLUE 12V Power 31 Battery Ground 85 Battery Ground 86 12V Signal from Temp Switch 87 BROWN 12V to Fan #1 87 WHITE 12V to Fan #2 87 12V Signal from Time Delay Relay Universal Hydraulic Oil Cooler OM 17 Set-up Instructions Hydraulic Hose Specifications NOTE: Any external hydraulic hoses are not included with the Loftness Universal Oil Cooler and must be acquired separately.

Male Connecting the Hydraulic Hoses Inlet Outlet Rubber Edging You may need to cut holes in the engine hood or sheet metal as the hoses pass from under the hood up towards the Loftness Universal Oil Cooler. Line the newly cut sheet metal edge with rubber edging. Hydraulically connect the roof cooler to the skid steer at the connection point determined earlier. 18 Universal Hydraulic Oil Cooler OM Set-up Instructions Check and Verify Fan Operation To Check Fan 2 1 Double check that all hardware is tightened to the proper specifications. Refer to "Torque Specifications" on pages 34 and 35. Recheck all the hydraulic connections before operation. Start engine and function loader arms slowly. Carefully observe for any hydraulic leaks using proper hydraulic techniques. WARNING: Do not use exposed skin to test for hydraulic leaks. High pressure oil can be injected into the skin. If oil is injected into the skin, seek immediate medical attention as serious side affects and death can occur. Remove the temperature sensor plug (1) on the main harness. Use a jumper wire or Deutsch plug jumper (2) (dealermade) to activate fan #1. Fan #2 will activate 25-30 seconds later. Preset 120° F temperature setting is non-adjustable. Check Clearances, Hardware & Hydraulic Connections IMPORTANT: Flying debris can gather on the skid-steer and needs to be cleaned off, especially around the radiator and oil cooler screens, engine compartment and exhaust areas. Periodic cleaning will help prevent the possibility of fire. See "Cleaning The Cooler" on page 21 for cleaning instructions. Raise cab and check that the hoses from the roof cooler do not pinch against the cab or hood structure.
