Restoring the Ferguson 20 or 30 is not too hard, many parts being interchangeable with the 8N and 9N Fords.

Tools: Not much needed. An impact, 11/16 and 11/16 socket, and some hand tools and two floor jacks.

Pop off the hood and fenders. Easy. Remove battery and gas tank. Place the floor jack under transmission and then remove the front axle assembly and then the engine. Elapsed time: one hour.

Engine overhaul is straightforward, by the book. All parts are available from suppliers except the block and head. (Good luck!) Prices are competitive. This engine is very similar to the VAC Case.

Now block up the rearend and remove the transmission. Replace bearings and reassemble by the book. This is a precision assembly.

Slide out rear axles and dismantle as required. Reassemble by the book. This is also a precise job. Brakes can be bought or relined.

You will see that the hydraulic pump is at the bottom of the case with no filters at all. How did it survive 40 years? Completely dismantle the pump. New parts are available, many the same as Ford. You may have to grind the valve seats. Damage, if any, will have been due to water or filth in the oil. The scotch yoke piston design of this pump makes it very durable. Blown up pumps are caused by water or ice. Go right by the service manual for reassembly. The draft control levers and gizmos are very simple, but may be bent or rusted. In reassembly of this precision tractor, pay close mind to tolerances down to .0001'. And pay close attention to gaskets and seals. The hydraulic pressure is 1200 to 2000 lb. per square inch.

Three pt. parts are often worn out. New ones are readily available, but are not exact look alikes. Mint used parts are hard to find. NOS? Get real.

You can buy or copy the wiring. See your MF or Ford dealer. In the engine, pay close attention to the oil pump and the valve springs. These things may be really tired. Oversize pistons are fine, but high compression may make it hard to start on 6 volts.

At this time you may consider an overdrive or over-under. The old Sherman step up won't fit. Most others will.

Some nice gauges are available. Shop around. Wheels and tires can be purchased locally anywhere. All seals and bearings should be easy to find or order. All nuts and bolts are hardened and rustproof.

Some glitches: Cracked heads can be fixed. Pay close mind to the governor assembly and to the distributor drive, or you may be sorry. Loose steering parts can be replaced or in some cases shimmed. The manifold is likely warped and can be resurfaced. The muffler connection can be refaced with a cup grinder. NEVER use borderline parts.

If you are careful, this tractor will serve your grandchildren as well as it did your grandfather!
