Re: Starting 4020 after Sitting 5 Years
Grab the fan and with the other hand, reach in and hold the slack side of the fan belt tight and you can turn the engine until you get up on a compression stroke. A worn engine will spin pretty easily. A good one, you will have to turn it slowly through each compression stroke. Hope you find the latter.
Also a good idea to check for water in the oil. Loosen the drain plug and see if any will drip out. Oil level may also be high on the stick because of water under it. Never know what might have happened in the time it was sitting.
No, you can' t pull it off to start it. If you have to pull it some distance, use the "tow" latch behind the left battery to disconnect the transmission from the wheels so it doesn't damage the transmission from lack of lubrication while towing. You should have manual steering, but not brakes! Not a real good combination while towing.
If you start at the starter solenoid terminal and follow the cables to the first battery post (what is it's polarity?) and then from the other battery terminal to the frame or straight to the next battery (what polarity is it's first connection from the first battery or frame?), and from that battery to the frame or starter (where does it connect? stud on the end of the starter or solenoid terminal)
You could have .......
series 6 volts (solenoid to +left bat- then to +right bat- to frame (ground) That's how Deere did it on the newer tractors
parallel 12 volts (both batteries are 12 volt and both + posts have connection to starter solenoid and both - terminals have connection to frame (ground) This is how I prefer to do it.
Series 12 volts (24 volt system) original design. Left battery + goes to starter solenoid terminal, left battery - goes to frame. Right battery + goes to frame, negative goes to terminal on front of starter. A starter with an internal short usually will drain the right battery only, the solenoid will isolate the left battery and prevent it from being drained by a bad starter. The accessory electrical equipment on the tractor is divided between the two batteries somehow, can't remember exactly how.
Our 24 converted to 12 volt cranks just as good as it did when on 24. The price of repairing the generator and starter was getting out of hand, so I converted it to a Delco 10SI alternator and parallel 12 volt batteries. Now our generator/starter man says the old Delco starters are getting too expensive to fix and has supplied us a newer model, slightly heavier duty Delco starter with a more durable solenoid on it. It has to be indexed correctly to clear the intake manifold and the side cover over the starter area will no longer fit. So far it's only been on a few months.
