70 electric start conversion

[KenL]

A friend brought a 70 diesel over for a
complete check over. He wants the pony out
and electric start installed. Does anyone
know of a complete conversion kit? If there
is one, what all has to be done, added,
deleted etc. He has his mind made up, no
changing it. THANKS

I did a conversation on a,70 last winter. The kit came from an outfit in Pennsylvania that advertised in green magazine. The number is 717-445-9465. The kit works great. It cranks faster than it ever did with a pony motor.

IMHO doing this conversion is kind of like farting in church....you shouldn't do it! But some people can't resist. To do a professional looking conversion you should remove the hood with the pony door access and replace it with a late 70 gas hood that has the gas filler neck closer to the nose cone. Also, the throttle pivot arm is mounted on the pony motor, so you will need the small bracket that mounts the throttle pivot arm on the governor housing around the the tachometer cable fitting. Also, need the JD block off plate for the side of the diesel block where the pipe going to the pony engine water pump was mounted. Got to have plug to block where the water from the pony engine circulated back to the diesel engine. Buy a new large 12 volt battery, rewire everything for 12 volts instead of 6 volts. Should also install a tank heater because the e/s will not crank the diesel engine fast enough at zero temps to start the diesel engine. Make sure the conversion kit you purchase has the small items mentioned above. In our area this conversion reduces the value of a 70 diesel..people want original. To do a good job you will spend $1000-$1500 to do it right.

I bought a JD 70 diesel a couple years ago that was already converted to electric start. I also grew up on a JD 70 diesel pony start. Honestly the electric start is so handy and quick. The tractor pops right off. It will even crank it without decompression and this is a strong running engine. I believe in my 730 owners manual it says if it will start you do not need to decompress. I do not start this JD 70 in the winter. The conversion I have is 24 volts. I do not necessarily like that. 12 volts would be so much more handy and easier to understand. Even if you understand how the two 12 volt batteries work together as 24 volts and individually as 12 volts it is still tricky. Not only tricky but the power/current is out of this world compared to 12 volts. It will fry wires quicky. I remember someone saying that the original pony motor is somewhere around 12 horsepower (I might be off some) and that you can't produce that with a 12 volt system whereas 24 volts comes closer. They even went as far as using ohms law to calculate the horsepower. I do agree that it probably would hurt the value to a collector. But, an old 70 diesel can still do a lot of farm work for some people and it has to start well and consistantly. So maybe if kept as a workhorse it could actually be more valvable.

V4 cranking engine will make 14HP easy in good tune .
Starters are usually 4,5 and 7 Kw .

 

[buickanddeere]

5Kw is 6.7 HP .
