340 - part II

Kirk Affeldt · Aug 17, 2013

After getting my new-to-me 340 home and in the shed, I preceded to use PB Blaster down the spark plug holes and let it sit. After a couple of weeks, I jacked up a rear tire and put it in 5th gear to rock the tire. The wheel and engine turned over! I have made a couple of revolutions on the tire and the engine has turned over a few times as well. I have a couple of questions to ask of your knowledge and experience as I am kind of a newbie at the restoration of a non-running tractor.

1. Am I ready to try to fire the tractor up, once I go through the points, plugs, condenser, coil, and starter?

2. Should I be concerned about PB Blaster seeping between the pistons/cylinders and into the oil pan? Will that harm the engine starting it/running it? I used a good half of a can over the two weeks of sitting-soaking.

3. What is a good method for cleaning out the gas tank? There is a kind of damp gritty residue in the bottom of the tank-my assumption rust with whatever is left of gas/gas residue.

4. Since this 340 has a 6 volt system, should I stick to a 6 volt battery or should I get an 8 volt battery?

Thank you for your thoughts and opinions!! It is much appreciated!!

To clean the gas tank you can fill it up with lava rocks and shake it. It can get tiring after a while but it does a pretty good job.

Question #4

An 8 volt battery is nothing but an excuse.

If it is a show or parade tractor and you want it original, then fix the 6 volt system.

As for me, if it is a working tractor I would bring it up to the modern day world. Convert it to 12 volt neg. ground with an internally regulated alternator and be done with it.

If your going to take the gas tank off,wash it out good with a pressure washer. If you don't have one you could wash it out at a wand type car wash. If they are real rusty I take mine to a radiator shop and have them clean in out in their caustic tank. Then you can use a pour in liner if needed while it is clean.

An 8 volt battery is nothing but an excuse.

Yeah, but if you want to keep the lights, starter, generator and just buy a battery, it's not a bad way to go. I had a S-55 Oliver and changed nothing but the battery. I had the tractor for several years and if I bought a 6V, it would last 2 years at best, but an 8v would last 4 years. That was the big advantage, not the added cranking power.
I have a 240U that has been changed to 12V. I haven't changed the lights 'cause I don't need them. The starter went bad and my "auto-electric" guy changed the field windings to 12v. because the starter would spin too fast and not catch the starter ring every time (just grind on it). If the previous owner had just installed an 8V, everything else would still work.
Problem is, 8v batteries are hard to find some times.

adequate[/b:1a33443a23] containers, change all the fluids. Capacities: oil = 5 quarts; hydraulic system [and this system does everything: power steering - if equipped with this option; pto; quadrant lever for fast-hitch or three-point connection and Hydra-Touch (control levers to right of steering wheel = hydraulic outlets]= 10 gallons and check the coolant system for strength of freeze protection = 15 quarts. The oil filter is a canister type under the tall cylindrical housing on the right side of the engine. The hydraulic filter is behind a six-sided plate located ahead of the brake pedals. Fill the hydraulic system by removing a round plug with a square recessed area which is located to the left of the shift lever. To check the 'full level' of this system, look below the left footrest plate. ~1 1/2" below said plate and 3" to the left or forward of the large hex-head bolt that holds the rear support bracket for the footrest, turn out a small bolt or slotted screw and fluid will flow from this opening when the system is full and all air is removed. You may already know this stuff and/or have manual(s). I think you did a smart thing concerning soaking the cylinders if the tractor hadn't been run since ???

Out late, frequent poster Hugh MacKay of O Canada land had his smaller off-set Farmalls start at -30 degrees with a [b:1a33443a23]good[/b:1a33443a23] electrical system = large battery cables, connections shiny, bright and tight. They were made to start and operate in all conditions. It's the operator that may not like all conditions and the tractor also if it isn't up to snuff. Good luck with your project and enjoy it!
