Gear reduction starters

[green northern lights]

Looking for advice & all input on gear reduction sterter, Is World Power Systems brand, a good starter or a cheap, poor quality starter. thinking of putting one on a 3020 D ;for faster cranking speed, for winter starts,.....

I've got two. One on a 1020 Deere diesel and another on a 2020 diesel. Both have been great. Only downside was making it fit on my three-cylinder 1020. It would of fit fine with the original fuel pump that Deere used when new. But the new replacement tin-can Airtex interfered with starter installation. Probably won't be an issue on a four cylinder Waterloo 3020. When my original Delcos crapped out - quality parts to fix were more then the cost of new gear reduction starter. Mine were $99 each.

Installed one like that and lasted a year starting a 3010, nose cone broke off and wedged in the clutch housing. chris

Why go to all the EXPENSE and concern as to whether it will or won't, when a MAGNETIC or a 1500w cats tank heater will do just fine, have for years at a FRACTION of the cost. ???? Put the heaters on a clock and if that tractor won't easily start in 2-3 hrs heating , get rid of it.

Utility tractor starter won't fit 3010.

I agree. If you are not using a block heater . You are just making life difficult for yourself.
Forgot about the de-stroker until somebody mentioned that vital starting assist.

Am not too fond of the way those gear reduction starters sound. Plus they do feel light-weight and cheap. Had one on a 4020 and it would barely crank it over fast enough to start (in summer). The early 3020/4020s were designed to start on 24v. So if you knock them down to 12v with a conversion, it's already cranking slower than it was designed. If you add a gear reduction starter, it might crank easier, but will be slower.

Anymore I just have my original starters rebuilt locally. That way I know what I got and that they fit. A traditional starter combined with the cold-weather starting aids listed above will serve you best.

Gear reduction starters are an upgrade in technology. GM and Ford started using them on their diesel trucks years ago. GM switched from direct-drive Delcos to gear-reduction Delcos (made in Japan) with diesels in 1988. Toyota did it late 70s. Deere started doing it OEM on bigger diesels in the late 80s. The gear-reduction NipposDensos used on Deeres held up better to abuse then the direct-drive Delcos did. We had a lot of DD Delcos with bad armatures, broken starter drive stops, etc.

Can’t comment on the specific quality of whatever Chinese starter you are looking to use. I’ve got two $99 gear reduction starters on two of my Deere tractors and they’ve been bullet proof. Same goes for two of my Ford diesel trucsk and two of my GM diesels.

A 12 volt conversion need not spin slower than the original. I have a 4020 converted and it has always spun faster AFTER the conversion due, possibly, to better connections and better battery balance. While I can't speak for the quality of the starter pictured I do know the better quality gear reduction starters DO spin the engine faster, quite likely due to the lower torque required on the armature, allowing them to spin faster. I friend of mine put one on his 4010 and it made a big difference. Mike

If it will fit the most powerful commonly available 12V stater is the PM gear reduction 44MT. It even looks like an ordinary starter without the offset.
The denso 12V PM starters are usually 4KW but 5 KW is in the parts book.

I was just getting ready to say what you just did.Mine lasted about a year on our 3020 then broke off wedged in and ruined the ring gear as well.Tractor did need a clutch but it could have waited until it suited.
