4020 gear reduction starter

[Anonymous-0]

do anyone make a gear reduction starter for a 4020? i find them for 30 series on up but not the 20 series.
thanks

Just put a 42MT Delco on it.

explian to me what ia 42MT is, or off of. mine has been switched to 12v, if that makes any difference.

Gary get a nependeno for a 4430 or 4440 it will turn her over good and out last a delco be 2

Do like Kent said and put on a Nippendenso starter off of a 4440. I've put quite a few on 4020's and 4320's. Put a gear reduction on cousin's 3010, nose cone broke off and got wedged in flywheel after a year, nose cone was aluminum. You know whats on that 3010 now?? Nipp.

The Delco direct drive starters went up in physical size and power.
On 12V for a "standard" starter.
The weenie 10T is 2.8KW, the same as the 28MT gear reduction.
37MT and 41MT are 6KW. 42MT 7.6KW and the massive 50MT at 9.0KW .
I think I can shoe horn a 42MT onto my JD 1640 with the proper two bolt nose cone. 37MT for certain. A few steps up from the 3KW Bosch.

I have the 35MT and it is "ok", its pretty half a$$ed for winter starting when its around 0. I was looking on jdparts and i didn't see where it listed what the available starters where other than Delco and Denso. If it did I missed it. I am interested in which is stronger the 42MT and the Denso starters. I don't have the luxory of the tractor getting the day off when it gets bitterly cold here. Eventually I will be able to build a new shed (with electricity) to park it in and then will be able to plug it in. Is the 42MT available from jd or do you have to find it elsewhere?

May not be room for the large Delco on an early 4020. The Gear reduction maybe the solution.

 

[buickanddeere]

Are you using a hydraulic pump de-stroker? A wonder item for a mere $15.00 .

 

[4020_1966]

I haven't gotten the destroker yet, but I will be getting one asap. Kind of running ragged the last few months. I looked up a delco dealer about an hour from where I live, I might go by there and see what they can tell me on it.

Part no se501403 is a reman starter for an 8330 and it will fit .I put 1 onb a 4440 and it turns over twice as fast as a nipendenso . It also cost $10 less I had an engine heater burn the cord off and it still started at - 10 no ether .There are different sizes I guess But the drictions that came with this part no . listed it as the highest power output . I did have to ad 6 in. to the 2 small wires. and drill the hole in battery cacle out to1/2 in. I also have a nipendenso starter on a JD. 4000 With new batteries and new altinator that starter is alot better then the delco but When I get a chance it will be change to the gear reduction starter as alot of times it has to be where it can"t be plugged in.

I do not understand the term gear reduction? It seems that the starter will turn slower not faster,(gear reduction). It seems you would need a gear overdrive?

 

[buickanddeere]

Usually a permament magnet motor.The current has a shorter path through the just the armature. Which assists in allowing high current with low 12V. Current is not squandered making magnetism for stationary field windings. High powered rare earth magnets take care of that.
The motors trade some size but make up for it by turning much faster than a direct drive. Gearing down is required to obtain a reasonable cranking speed,with enough torque.

M w J, what brand of starter is the se501403? I looked it up but couldn't find out anything other than what it was a part for. I am interested in this and the 42MT starter.

Gary, the gear reduction starters increase torque by reducing cranking rpms. The Roosa-Master injection pump on your tractor needs lots of rpm to build sufficient pressure to inject fuel into your engine before it will start. If you want your tractor to start well use a nippondenso starter from a 4440 or late model 7700 combine.

It is a reman denso gearreduction from JD we have had good luck useing there remans. It is also cheaper then the nipendenso.

The gear reduction starter motor turns about five times as fast as a nipendenso Then with the gear reduction it still turns about twice as fast at the drive gear . I know if you had one to try you wouldn't think twice about which one you wanted.
