1941 H manifold

PJH · Sep 13, 2012

My grand-daughter (senior in high school) and her dad are working on her great grandfather's 1941 H. The manifold is rotted out and they are wondering if all H's use the same manifold. The new manifold that they are looking at is listed as being for an H with a distillate engine.

Thanks,
Paul

Yes Paul, there were at least 2 manifolds: gasoline and dual fuel (distillate). both work, both fit. I also believe there might have been an afternarket one as well. They all fit. However, if the H was not setup for dual fuel, no need (in my opinion) to use a distillate manifold. Plenty of decent used ones and new ones on eBay.

Being a '41 I would bet that the tractor WAS set up for distillate. Most have been converted to high compression engines by now. I am a "correct police" person so if my tractor is a distillate tractor it gets a distillate manifold, starting tank, etc.

The way to tell if it was a distillate tractor would be by looking at the serial number for the lack of an X1 suffix OR by looking at the hood for an extra hole (there may still be a small 1 gal starting tank)

I believe it would need to be NOS (new old stock) there is a market for distillate manifolds and heat shields that is unfilled I no of no manufacturer or supplier of original, or replica distillate manifolds. The price of a gas replica new manifold will be (probably) 1/2 of the price of a NOS distillate. If either is a new casting, they are to be suspect for fit and spacing. Many are cast in developing nations, and need more development. Jim

OK - thanks for the advice. We noticed that the manifold that this site has for sale is probably better suited for their tractor. We were wondering how to tell if it was originally a distillate engine. I'll pass the serial number prefix info on to them. It's been a while since I've seen the tractor, but I only remember one fuel tank. Thanks again - I'm sure there'll be more questions as they progress.

If the engine has never been replaced, it can be pretty clearly defined by the presence of shutters (or parts of shutter systems on the radiator, serial number not ending in X1, the finding of residual small fuel tank in front of the big fuel tank on the rt side, and head part numbers. Found inside the valve cover. a replacement engine is really subject to the head part part numbers..Jim
