YM1700 won't start

[California]

Yanmar Tractor Parts: STARTER ASSEMBLY ^SALE WAS $399^

I went and read that description. No question, Aaron's starters are top quality. If I earned my living with my Yanmar that's probably what I would buy.

I remember when the ebay guy was telling his customers that his broad-application 11 tooth starter could replace the (proper) 15 tooth Yanmar starter, and it should have been obvious to everyone that this wasn't going to end well. That seller is now long gone.

My starter came from rareelectrical. Take a look at his ebay feedback. Over 40,000 feedbacks! Just now I went and read several pages. The most recent neg, about 250 lines down, was a customer who found UPS's standard, stated, shipping time intolerable. The next was someone who couldn't get 24 volts out of two alternators in series. The next two could have been bad product or bad install, it's not clear. Overall after reading all that I have the same impression I did when I bought my starter in March 2011, this is just generic Chinese clone replacement stuff like they sell at Autozone etc. My experience is like the majority of those 40,000 satisfied rareelectrical customers, the starter simply works.

Since the engine catches an instant after dropping the compression release (and the starter has the correct number of teeth) I don't see how it could hurt the ring gear. Surely that problem would appear within rareelectrical's 40,000 feedbacks if he were selling starters that weren't up to standard - and it hasn't. I'm happy with mine.

Or - if you prefer - the stock starters are standard Hitachi or NipponDenso gear like on most Japanese cars. Any starter/alternator rebuilder should have the parts and expertise to rebuild it. For me I wanted to try this high output clone starter and it has met my expectations.

Is anyone interested in buying my old starter? As I noted above, it's slow and so could probably use a professional rebuild. This was the starter specified for later Yanmars, not YM2000. Part # YM121120-77010 Denso 028000-5730. It has a 2003 date written on it; I assume that was the last rebuild or rebuild warranty-expiration date.

I decided to take my chances with the same Rare Electrical starter that California bought. I purchased it on Ebay for $100 including S&H. Before I installed it, I made a few measurements. The diameter of the gear matched the stock starter. I also measured how far the gear extends when engaging the flywheel during starting. It extends about 1/8" further than the stock, which I decided was ok. The bolt holes matched up as required. One issue I had is that the main fitting was about 0.01" too big to fit into the hole. I'm pretty sure I determined that this was not a problem with the starter but rather some imperfections sticking out on the engine side. I used sand paper, smoothed them out and was able to mount the starter flush as it should be. I connected up the electrical connections and VROOOOM! It started almost immediately. (BTW, it happens to be unseasonably warm today (~55 degrees) so that is obviously going to make starting easier.) I'm just glad it started at all! Time to celebrate... Cheers! :drink:

California and Ginormous... Could you guys tell us how these starters are holding up... Any problems or damage to the flywheel...

Just saw this thread and my starter is slow as well. I give a rebuild a shot and if no improvement may go the same route with the $100 replacement.

I too am interested if the warnings manifested themself?

:thumbsup:I believe that is the same starter I used on my YM2000 two years ago, still works great.

It continues to work like new. Spins fast and starts instantly.

How in the world do you get the top bolt on the starter out?I've had mine off a couple times and boy that bolt was a pain!!!!!!!!!1

I have a vague memory of using a long 3/8 extension and a socket that had an integral U-joint. But that may have been on something else.
