A quick search on Ebay found (4) John Deere 400 muffler cowl/shields if that helps.

I was literally searching every term but "cowl" lol. Thank you!

Is the crankshaft center height on the original kohler twin comparable to say a single cylinder k series? Or does someone have the measurement around? trying to plan my engine mount from my cubicle at work

 

[raven007]

Started work on the mount. Got it all tacked together but I will need to lower the engine .25 inches. Which means grinding the new portion back off and milling away the leg of the angle to drop it. I kind of had the feeling I should have been using 1.25 instead of 1.5 all along. But I could not get a precise measurement from the junk K series powered genset regarding crank height so i winged it. Anyway...pics....

Looking at the pictures-if you have a reasonably intact belly screen, you may want to try to save it. They are kind of hard to come by and somewhat painful to repair with the really light weight perforated metal.

It isn't too terrible. Been hacked up a little bit at the rear though.

Has anyone fitted a 318 cooler to a 400? I am looking at different options.

I did a repower several years ago and went with a kit from Repower Specialists. I had a thread on my build on here, but since Bill Falosk looked at mine and his is gone, I assume mine is too. My kit included a Kohler CH730 too. For what it is worth, I do not believe that is the correct hydro cooler on your machine. I now have two 400's and both of them have a much more "blocky" cooler. Neat thread. Keep it coming. Good luck.

Ditto on the oil cooler. About 4 years ago I rebuilt the engine on my 1982 400 including reboring 20k over. turned out very well. but this year a opted to repower my 1983 420, using Kohler CH640 which I think is the same block size as the CH 730. Turned out very nice. Glad I repowered.

Yeah, it is something definitely cobbled on. I have been slowly collecting pieces for this. Mostly wiring connectors and odds and ends.

I did score a D722 Kubota. But its in a semitruck APU pack. I don't have the heart to tear it apart, plus I may end up putting it on my box truck to provide A/C and heat to the box as well as power.

Back on this.... lots of life happenings pushed it to the side.

Still looking for an answer on whether a 318 cooler will fit the 400 operator station width. I will probably end up going with an aftermarket transmission cooler if not.

Is the fan on the 400 driveshaft super critical if an ample size cooler is fitted in the system?

 

[Merc1973]

I fit a 318 hydro cooler in mine since the 400 was leaking. I removed the fan from my old driveshaft to install on the custom ebay one i bought. It takes patience to remove. I suppose if you have a remote cooler with an electric fan that would be sufficient.

How is the project going?

I ran a 400 with no fan on the driveshaft (pump end of it) for at least 5 years. Probably closer to 10 years actually. It saw lot of hot summer days in my beater 400 with no hydraulic heating issues that I know of. The oil cooler is in pretty good shape and I always clean if off after every mow with compressed air. I'm still running it like that but it doesn't see a lot of mowing time these days. My 420 does most of it now and my 8N pitches in too. I'm not recommending anybody leave their fan off. I'm just saying that's what I did and it worked fine in my case. But as usual.. YRMV (your results may vary).
