Mon Apr 19, 2004 6:24 pm

Hey, new to the site and I'm looking for help. just started working on the cub since last year and it seems that the coupling on breather pipe, on the air cleaner assembly has disappeared. (part #350 755 R1). called my local IH dealer and he said it was discontinued, searched every hardware store in the area the area but no luck. anyone got an idea where I can look next? is this part a real big deal ? does it really effect performance ? thanks for any help.

If you can't find the fitting at a hardware store, I would suggest you try calling or emailing either or The line that attaches to that fitting sucks oil fumes out of the block (like a pcv valve on a car) and burns them in the engine. While you have the line off make sure it and the fitting at the other end are not plugged. If it's blocked you will get oil vapors out the oil filler.

That is a discontinued part but the "Parts Depot" has some on hand. They only sell to dealers. So you need to go through a dealer that is willing to order from them. I don't know if Bermuda Ken buys from them or not. As far as that goes, Ken may have one on hand too.

Didn't at some point they stopped installing it at the factory? My '74 doesn't have one. It looks to have been plugged from the factory. If not, may be the source of some of the "blow-by" out the filler cap??

Thanks for the info. I have been to every hardware store in a 20 mile luck. I will email jp tractor salvage, and see if they have one, and if not maybe the local dealer would call the part's depot. Hey John, I used to do alot smallmouth fishing on the Courtois and Huzzah... sure is beautiful country!

Now that I know which part it is you are looking for the answer is clear :roll: :lol:

I had the same problem on Ellie-Mae. Could not find that part for love nor money. Then a thought hit me - Fairview Fittings! (local company) Eureka :!: Not only that but I found that Fairview was a good place to get most of the brass/bronze even s/s fittings that no one else seemed to have whether it be for my Cubs or other engines/tractors (read lawn tractors).

Any quality pipe fittings dealer in your area should carry it. Take the assembly with you and the old fitting if you still have it. You may be better off to get new fittings both ends and a new pipe flared while you are at it. I did.

Chuck, sometimes I don't think too fast, but the best place to find your fitting may be an auto parts store rather than a hardware store. That's where I got the brass radiator drain plug for Missy.
