Desperate Part need for JD 750 engine!

[Mountaineer Deere]

I am in desperate need of 3 rocker arm studs and nuts for the Yanmar 3T80UJ engine in my JD 750 tractor. Any ideas or does anyone have a old head with the studs in it? JD part number is CH15433 it's no longer available from John Deere.

What other tractors use the same engine? Must be stocked somewhere if it's a popular engine.

Don't know but I've searched aftermarket and everything on the internet. Was hoping maybe somebody had an old head laying around that might have the studs.

Checked with Aftermarket.Express thought they had them ordered them, in about a half hour got and email they said they were sold out of the they hadn't update their inventory.

Having the engine rebuilt. The Mechanic (Friend of mine) was putting it back together and he stripped all three studs. So I'm dead in the water right now.

I'd sure give Hoye tractor parts a call. When rebuilding my 950, they had the same parts as Deere only cheaper.

Why not get some threaded rod{probably metric} & make your own??

Why not just use a bolt?

OH.. & get your mechanic friend a "book" w/ the torque specs.. Lol..
Why would u KEEP GOING after u stripped the 1st one?? Lol
I really don't need an answer.. I just thought it was funny..

take the studs out and measure them and the threads. An auto parts store may be able to match them up or find online

Get the right parts, one time.

Get the dimensions off of studs and then look them up on ARP dot com they make high strength studs, bolts, nuts for every engine ! there will be something that will work!

What are friends for? A long, long time ago, a friend, also an apprentice mechanic put my brakes on backwards. When they made noise, he told me to get speed and slam on my brakes to seat them. Did a really nice job on my freshly turned rotors.

It's not like you need a head or the rockers. You have to be able to find something. I have had reverse fine thread bolts made for me, in the US, and it wasn't that much money.

There are a bunch of Studs on E-Bay, under Yanmar studs. But it makes me see that going to a marine source might work. Also, forget about JD, Any rebuilder that does Yanmar should know a source for the studs.

If you haven't found them yet this site has them or at least they show as having them......Don

Sorry to hear about you dilemma but I have to point out that when people say parts and support for the common brands like JD are the reason they stay with a brand or are willing to pay more when shopping doesn’t seem to be as true as it once was.

Now to help with the situation search for the parts used from a wrecking yard. The tractor was fairly common and finding them used should be fairly easy. Compared to having them made or trying to match them to an other engine even if they are close they may not be exact and my experience building engines tells me that when it comes to valve geometry close isn’t close enough when you want it to last a long time.

Good luck finding them.

 

[Mountaineer Deere]

Thanks to everyone for your input. I ended up having them made by a local machine shop. Thanks again

John Deere seems to like changing old part numbers which doesn't help!

That's true but if you type in the old part number at the dealer it will cross over to the new part number.
