jd 750 want to replace yanmar

[jdg750]

Anyone know of an engine cross reference list for
John Deere engine # to corresponding Yanmar #'s.

Also, does anyone know if another engine with a little
more power can be mated to 750 housing?

John Deere wants an open checkbook to start looking at
my engine, and I was hoping I could find a replacement
new or possibly low hour engine. Thanks. /forums/images/graemlins/confused.gif

There should be a Yanmar nameplate somewhere on your engine that will give you the Yanmar model number of your engine (somewhere near the top if I remember correctly). Take a look and go from there.
Can your existing engine by rebuilt by a diesel repair shop? This may be your cheapest way out.

Id try to have mine rebuilts whats the matter with it a knock, rattle orr has it totally puked. I spent a few days last week changingthemotor out in the scraper at work. Ill rebuild the old one for a spare this winter.

Thanks for the replies so far.

My engine loses power after it warms up (won't mow tall grass & weeds with brush hog without bogging down). It makes a 'popping sound' that reminds me of the early john deeres. The local dealer wants to start replacing parts & charging labor until 'it is fixed'. I'd rather spend my money on something that should be a better fix long term... like a new engine.

I also tried to contact John Sheaffer via the email link but his email hosts rejects my email. Does anyone have his phone # & or address.

Thanks

Thanks to those that replied....

I didn't expect a miracle.... after reading about the new government mandated diesel fuels and also about additives that increase lubricity & replace aromatics.... I switched diesel suppliers and started using an additive. I'm on my third tank full now and the engine seems to have a new life.

It is definitely a lot stronger & the 'popping' sound under load is going away.

It is able 'brush hog' bermuda about a foot high & thick. When I first posed my question it wouldn't do that anymore.

Thanks again.
