Explanation

Early production YP Planters and Air Drills were not manufactured with fan motors that utuilized a case drain connection. If there are only two lines connected to the fan motor , then the case drain connection is not utilized. If there are three hoses connected to the fan motor , then case drain is utilized.

The purpose of this guide is to show the port locations for connecting case drain and motor return for Great Plains YP Planters and Air Drills that utilize continuous flow fan motors. The information obtained for this guide was taken directly from the tractor manufacturer’s information that is available on-line and through tractor dealers.

Since tractor equipment and options vary , the connections shown in this guide must be verified through the tractor manufacturer or dealer to prevent damage to the tractor and implement hydraulic systems.

Great Plains continuous flow fan motors require case drain and motor return lines to protect the motor during use. The case drain line must be connected first, then connect motor return line before connecting the pressure line. Failure to do so can cause damage to the motor seals. When disconnecting, always disconnect pressure, then motor return, and case drain last.

Case Drain

This connection is required to carry the motor case internal leakage directly to the tractor hydraulic reservoir (sump) with zero pressure. This oil serves to lubricate and cool motor components not directly exposed to the working oil. Great Plains supplies a 3/8” body size ISO 16028 zero pressure flat face case drain male coupler on a 1/4” hydraulic hose for the fan case drain line. It is normal to have seepage from this fitting when disconnected from the tractor to protect the motor seals from thermal expansion. If the tractor is not equipped with a female flat face case drain coupler , then it must be sourced through a tractor dealer or hydraulic supplier.

Motor Return

This connection is required to carry the low pressure return oil from the motor to the hydraulic reservoir or charge circuit. Using a motor return port prevents accidental reverse operation and possible flow checking of the return SCV coupling. Great Plains supplies a 3/4” body size ISO 7241-1 Series A male and female coupler with each YP planter and air drill. The male coupler is installed on the 1/2” or 5/8” motor return hydraulic hose from the factory. The mating female coupler must be connected to the tractor motor return port. The motor return hose and couplers are large to reduce back pressure to the motor.

Tractor Requirements

Tractors connected to Y P Planters and Air Drills must meet the following requirements:

1. LS Closed or PC Closed hydraulic systems with a case drain connection and a motor return connection. Open Center hydraulic systems

MUST NOT be used.

2. Verify the tractor Hp meets the requirements listed in the Specification section of the planter or drill Operator’s Manual before connecting.

Tractors Equipped with Additional Accessories Connected

to Case Drain and/or Motor Return

Some tractors may be equipped with additional accessories that connect to power beyond connections on the rear of the tractor (i.e. auto steering). If the case drain and motor return connections are already in use, then tee’s can be installed to add connections.

IMPORTANT!

DO NOT tee case drain into motor return. Case drain must have zero pressure return. Great

Plains warranty will be voided if case drain has been connected and/or teed to a motor return line. Case drain should only be returned directly to the hydraulic reservoir. The case drain line must utilize an ISO 16028 coupler that will allow seepage due to thermal expansion when disconnected from the tractor.

If tractor case drain circuit is filtered, it is necessary to make sure to have a clean filter to prevent excessive case pressure. High case pressure will cause motor seal failure.

DO NOT connect the fan motor to power beyond pressure. Continuous flow through the power beyond will deprive the tractor rear differential and pto drive gears of hydraulic flow and cause damage to the tractor.

Some tractor manufacturer’s have chosen to use the same type coupler for power beyond load sense lines as for case drain lines. It is very important that these not be confused to prevent motor seal damage. DO NOT connect the case drain hose to a power beyond load sense coupler.

Some tractor manufacturer’s recommend running motor return through a tractor SCV return port. DO NOT run motor return through a tractor SCV return port. Minimum pressure on most tractor SCV return ports is approximately 250 to 300 psi. Only connect motor return to a motor return port. Motor return ports allow pressures less than 50 psi, which prolongs motor seal life.

Failure to use the correct motor return port can cause oil starvation to the transmission pump and hydraulic charge circuit on some tractors. This is caused when oil is returned into the differential housing rather than the transmission or hydraulic charge circuit.

Make sure all hydraulic couplers and hose ends are clean before connecting.
