Ford Tractor Repair Manual Model NAA, NAA Golden Jubilee

RandR ENGINE WITH CLUTCH

15. To remove the engine and clutch as an assembly, first perform a front split as outlined in paragraph 5; then, proceed as follows:

Shut off fuel and remove fuel line. Unbolt the fuel tank support brackets from engine and lift fuel tank and brackets from tractor. Remove exhaust pipe.

Disconnect proofmeter cable from hydraulic pump. If equipped with a live power take-off clutch, disconnect lines from power take-off pump. Drain hydraulic lift and detach pump pressure and suction lines from differential center housing. Then, unbolt pump from engine and remove pump and lines as a unit.

Disconnect battery ground strap and wire to starter motor. Unbolt and remove starter from engine. Remove choke rod, throttle link from bell crank to governor arm and remove engine oil pressure gauge line. Disconnect wires from coil, distributor and generator. Remove temperature gauge bulb from cylinder head.

Attach hoist to engine, remove bolts and cap screws retaining engine to transmission housing, work engine forward until free of engine clutch shaft and lift engine to bench or engine stand.

CAUTION: In cases of low engine oil pressure, remove the engine oil filter cartridge and inspect for being dirt-clogged or for being wrong type for use in the full flow oil filtering system. In either case, a by-pass valve located in the filter cover retaining bolt may open and allow the engine oil pressure to drop to approximately 4-7 psi.

If in doubt, renew the oil filter cartridge using cartridge meeting Ford specifications and recheck engine oil pressure before attempting repairs to oil pump, relief valve or engine. At a nominal cost, an adapter plate may be obtained which allows installation of the later design throw-away type oil filter.
