what is the part number for exhaust manifold that most small block john deere's are running in super farm.

Re: exhaust manifold September 02, 2016 06:52AM
I believe most are using a 7920 manifold pn R505566

I have the popular center outlet with spacer and tapped holes for computer probes, $150 plus shipping. post contact number if interested.

So is your manifold 7810 or 7920? I believe both are center feed? Will that fit under a 4010 hood?

Part number on the manifold is R-131187. It comes with a spacer to position the turbo above the valve cover. These manifolds have been used on many 4010's and 4020's. Should have no problem under the hood depending on the turbo. Precision or Harts should be ok, many superfarm pullers also ran the Columbus HX-60.

Anybody have pictures of this setup fitting on a 4010 and under a normal hood? Gonna be using a S300 size turbo.

3010jd 8.1 manifold with a s300 will fit under the hood of a 4020 you will have to drill a new hole for exhaust. a person should run a turbo blanket or heat shield so you don't burn the paint on the hood it will get hot
