544 manifold

The part number a CNH dealer gave me was 398071-R1. But, he wasn't sure if that was right. The numbers I keep seeing on the net are 406046R1(pic shown here). These manifolds fit the engine but the exhaust ports are located a little further back towards the rear of the tractor. I can get a new one of them for 120 bucks. Would the only thing I need to do is cut a new hole in the tractor hood?

They can be repaired, as I had done with mine, so I could have a good spare if the need did so arise. I took mine to a welding shop. I am not sure what it is they use to repair a cast piece, but they did do a decent job. It only set me back $42. It isn't the cleanest weld alive, but I'm not sure what options welder's have at their disposal when it comes to cast. I bet someone on the board here will know exactly what they use.

Good luck!

It is a bit of sticker shock when you have to purchase one. I could see a couple hundred bucks for OEM, but when I was quoted $379 I almost launched my cookies.

I'll see what I can do for you, I hope I can still find that invoice with the p/n on it.

Here is a pic of the manifold. It has the exhaust port all the way to the right in the pic.

I'll see if I can dig that info up for ya. My manifold cracked between the first and second cylinder. That seems to be the main place for failure on that particular manifold.

Lets try the pic again.

I did look for the invoice to get you that p/n, but couldn't seem to find it. I'll see if I can get a hold of the CNH guys and still get it for you though.

That manifold is very repairable if done with
oxy/acetylene cast iron . I do many manifolds and other cast iron repair. Below is a link to some repair .
