I have a 433I that I wanted to upgrade starter on to help it turn over faster for easier starts. When I asked my AGCO parts man about using a Iskra type (japanese) starter for this, he said that I should try taking a AC 185's 649 starter and swapping into the 433I engine. Apparently, he said that the 185's were equipped with a 2x faster starter motor. Anyone done this?

I used to have a 6080 and a 185 I thought the 185 starter might be a little to long. would be a good idea. I can remember the 6080 always cranked slow compared to the 185-190-190XTs

Id stay far away from an Iskra, we used to use em in the construction line and had boo coo problems with em. A 185 should have the Lucas starter which is shorter than the ole stanby Delco starter. The Lucases had weak fields and wouldnt take near as much as a Delco. I dont think the Delco will fit the 433, Im thinking they came with the Lucas. I dont know about the speeds, I was under the impression they were the same. Sounds like yours might be getting weak. HTH

I called my starter supplier & he explained that the 433 starter is a class 25MT while the 185's 649 starter is a 35MT class. Apparently, the 35MT is much bigger in size, so it is not an option.

Check the bearings in your starter. New ones are not hard to put in and often make quite a difference. If the old ones can't be driven threw run a tap in the old one. Screw a bolt in and pull the bolt and bearing out.

The late-model 8010 tractors used a gear-reduction starter that is much smaller in physical size. Might be an option?

It matters a lot who built or rebuilt your starter. The guy I used to work for has about 13 855 Cummins irrigation engines, so we'd go through 40MT starters quite often. The local NAPA carries Wilson rebuilds, and the Federated Parts place carried Anderson rebuilds. The Anderson starters could be cranked with just the 00 jumper cables, but the Wilson would use a 1000cca battery plus the jumpers, and would never crank over as fast as the Anderson. Good cables with marine posts will help too.

Get a nippondenso gear reduction starter and you will never be sorry. Run from a lucis, they were junk when they were new. MACK
