4020d gear reduction starter

[CP4010]

I just saw a kit on eBay with gear reduction starters are these any good I need to convert our 66 4020 over to 12 volt. I am having a lot of electrical problems and I am tired of fighting the 24 volt system. If these kits aren't any good who sells the best kits thanks

There is a 5KW version of the Denso that will crank the engine
faster than the common 4KW Denso.

stay away from the Delco.

Some tractors are too tight to the intake manifold for the gear reduction starter to fit. I have one customer that has one on a 3020 and really likes it. I tried one on a 4020 conversion but it wouldn't quite fit under the manifold. Ended up using the Denso on that one. I would purchase it locally in case it doesn't fit.

I'm surprised that it fit on the 3020, the older intaks are in the way...

 

[Cliff Nelson]

It's also short enough that it fits with the dual fuel filters.

Where do I get a kit with the better starter. I don't want to convert it to 12 and have it not start good. I made that mistake with the 4010 we had it wouldn't crank the tractor very well if was even thinking about getting cold out. The kit made the electrical easy to work on but it didn't start very well.

Be sure you get Nippo starter, not the china nippo look a like starter, one is made in japan the nippo "style starter" made in china, and we all know what that means

I really would try a 12/24 switch if you have a good working 24V
starter. We used one on a army duece and 1/2 many years ago and
it worked well.

They are about $125

Here is the link to the switch.

I did the conversion on our 4020D couple of years ago and have
regretted not doing this.
Series Parallel switch

I just changed my 24 volt positive groung system over to a 12 volt negative ground system. I purchased the kit from Abilene and I couldnt be happier. The tractor starts fantastic and I am so happy to be rid of the 24 volt system. I couldnt have done it without the assistance of 1966 4020, Charles set me a pdf file on how to convert the system. It was about 15 pages, but well laid out. The biggest problem was working the alternator bracket to line up the pulleys. The pulley from the generator will need to be swapped with the alternator pulley, but it will work fine. If you need the pdf file just ask and I will be happy to forward it to you.Charles thanks again for sending me the file.

I would assume somebody other than mother Deere
could supply a 5KW Denso?
Doesn't a Delco 42MT bolt in place of where the
factory 37MT is usually found? Cheap as dirt.
How about the new Delco 44MT ?

I sure thought you posted a JD part #?????? part # RE528619

 

[buickanddeere]

I wonder what the Napa price on a Delco 44MT and 42MT
runs ?

 

[CP4010]

Is there anyone out there that sells a kit with the good starters or do I have to buy all the parts separate to do a quality conversion.

 

[Tx Jim]

Personally for the cost of a kit I think one is wasting money. All you need is an Iskra starter for about $325,a Delco Alternator,hook the two 12 volt batteries in parallel with the batt A & B(blue & brown wires) supply wires at the starter solenoid attached to top post on solenoid. For detailed wiring instructions give a shout out to Hayfarmer Frank on this forum.

I'd stick with the nippin denso starters. The are rebuildable and almost bullet proof. The gear reductiosn are nice, but on some do require a different intake and pipe. I can get new or reman starters, alternators.
Email is good.

How much is a Denso starter that will fit a '68 or earlier 4020D?

 

[4020_1966]

I have a 4kw Denso on mine and it fit great, cranks great, and I love it. It was approx 430$ 2 years ago. I also upgraded to a single huge 12 volt battery (1550 cca) soon there after and that woke it up even more. I am thinking it was se501403 for a part number. you can find it under 4430s etc. The 5kw Denso is listed on most of the newer larger engined JD tractors and it was less than 500$ then. As I recall it is 'supposed' to fit and you will have to drill out the battery cable end hole to accommodate the much larger stud on the starter. I was not able to put eyes on one to see how much larger if at all it is so I went with what i knew would fit. Don't forget the 2nd starter solenoid to make sure the primary one gets full power to energize it correctly as the key switch can not provide enough current itself.

Oh, and you asked about the kit, I do not know of any kits with other than the delco starter in it. All you need is the alternater with pulley, the starter, the directions and a couple of little wires you can buy separately from JD for about 20$ or so (the diode containing wire from the alternater). The alternater is about 120 or so, just make sure you get it from a place that will get you the pulley for less than JD (they want 110 for the pulley alone). The extra solenoid you can get OTC at any autoparts store as its an old Ford turck starter solenoid and a large worm gear clamp that holds it on top of the starters own solenoid. If you buy a kit you will get the bad Delco 35mt starter 2.5kw starter most likely and they barely crank in summer let alone winter. jD charges 650 or so for their kit or they did a few years ago. I did dad's 4020 the next year just finding the individual parts and it went great till i found out about the alternater pulley. I think I still ended up less than buying the kit but not by much. Hope this helps some.
