Aftermarket Starter Update

Traditional Farmer · Oct 31, 2014

Well I ordered an aftermarket starter from a company called Rakuten for my 1650 Oliver with reduction drive was $133 free shipping came the 2nd day put it on the tractor and it spun the engine great and it fired right.Guaranteed for a year.Its smaller than the original but seems to have just as much or more power.Estimated rebuild on my old one was considerably more.I'll hold onto the old one to see how this one holds up.

When I was selling reman starters, among other things, the rule of thumb on starters was if they lasted through the first dozen cycles, they'd last forever.

I have 2 starters and a gen I bought off the www for great prices and all are still functioning. The first starter was on one tractor and the gen on another and a few years later added the starter to it. Probably have 10 yrs on the first starter and gen and about 5 on the second.

I've had similar results like Goose said. If they make through the first dozen or so starts they're good for along while. We've had ones that didn't make a week and others that are still going.

A PM gear reduction starter usually has higher electrical efficiency than a classic direct drive starter that powers the field and armature.
A typical PM starter drawing 400Amp at 10V will be cranking the motor faster than a typical direct drive starter drawing 400amp at 10V.

I put new Chinese gear-reduction starters in two of my John Deere diesel tractors and two in my Chevy diesel trucks. $99 each except of one that was $129. Work great, zero problems.

A PM works by E=MC2. The small wattage used to charge the magnet would soon be used up in a few starts if it didn't.

Teddy - that is way over my head. Please explain to this dummy.

What is in a magnetic field is matter in motion, traveling and spinning at C which is the speed of light and the speed of electricity. It is not coincidence that they are the same. The power of a magnet comes from the atoms of the material. You can try to charge a piece of wood, but it will never align its atoms to produce a magnetic field. But there are man made mixtures of materials that will align & produce a strong field when charged by a stronger magnet. But it only takes a few watts to align the atoms & after that a pm is producing its own power by E= mc2. E is energy, M is mass (matter in motion) C is the speed of light (186000 miles per second) times itself because it is spinning at C also. The magnets in a starter will last for years if the right material is used to make them. If they weren't making there own power, the small wattage used to charge them would be used up in a few starts. Clear as mud? Any more ????S

In B&D example, the 4000 watts (400 amps x 10 volts) in a regular starter is split between the fields and armature, whereas in the PM starter all 4000 watts are going to the armature and the PM field is making its own power (E=MC2) so the PM starter will spin an engine faster.

I have found that the PMGD starters not only crank an engine faster but they usually last a lot longer. On the other hand when they do need repair they are usually so worn out all over that it is not cost effective to repair them.

Teddy - I still don't understand it but I'll let it go. Some things will just have to remain a mystery.

I understand. Most people think E=MC2 only refers to bombs and fizzle physics, but it is how magnets get their energy too.
