641 Intake air tube and hoses

[Steve in IL]

Looking to restore a 641 to the original style metal tube
going from the air cleaner to carb. It currently has a flexible
radiator hose installed. This website sells the metal tube,
but does not indicate what size rubber hoses should be
used on either end.

Any suggestions?

Simply measure the diameter of the carb intake and then go to a n auto parts store and buy hose that size that will hold up to gas

6** series tractors used molded rubber hose as OEM equipment.

Available from CNH, DC, others.

Hmmm. I think, based on looking through the parts book, that the metal tube was original. Perhaps its been replaced by a rubber tube.

Not on the 6/7** series tractors.

As clearly labeled in your photo, 8/9** series tractors only.

Dean, while I agree, that is what the drawing is labeled as, it is the only example for 1958 gas models in my parts book. Further, Yesterdays Tractors parts look up identifies the single piece rubber tube as Air Cleaner Hose - Rubber air cleaner to carburetor hose is not like original metal tube.

But Im starting to think that youre right, because the part number 311112 references up to the single hose, and no 6x1 is listed for the rubber hose connectors. Interestingly, 6x0 models are listed to use the (2) rubber hose connectors.

He said restore to original!

Hose is hose and you cannot tell the difference as it being Ford hose or from an auto parts store

Why is the air cleaner outlet coming out at an odd angle? Shouldn't it be vertical? How could it possibly mate up with the 90 degree intake pipe and short hoses?

I don't think that's the original air cleaner.

It's the OEM AF but not the OEM hose.

6** series had angled connection tube.
