    Is this stuff necessary???

    Removed radiator on our 2440 due to overheating problem...waiting on replacement... When we pulled the radiator, we found a couple of pieces of dirty stuff looking sort of like a foam seal or cushion. Found parts on JD Parts but local dealer said the two longest (of the several pieces) would cost about $200. Do these pieces perform some necessary or useful purpose? Could some more reasonably priced alternative be substituted?

    On the garden tractors the foam is essential to making sure air moves through the radiator not around it.

    3m does have foil faced, sticky back, 1/2” foam insulation that people use.

    What is your serial number? I see there are two different catalogs. Are the highlighted strips shown below the pieces you need? What about #7 and #8?

    If the diagram I posted above is the parts you are looking for, the dealer may be blowing some smoke. JD Parts lists the replacement for the 16-inch long piece (#27) as a 60-inch long piece that you cut as needed for $29.50. You could probably cut the other long pieces from the same strip. The strip they reference for (#24) isn't available anymore but I assume you could use a section of the 60-inch piece as the one side is only 16-inches and the other is 10-inches.

    If I add up the cost of all the foam pieces other than #24 it only comes to $84.

    Like others have mentioned, you could probably source some generic foam strips. JD Parts gives the full dimensions of every piece of foam used.

    Thanks for the replies

    Thanks rydplrs, I'll look for some of that 3M tape.

    Thanks jgayman. My serial number is 2440 F 382208..I think that puts it about 1982 production year. My son pulled the radiator and said the trashy stuff was all he found. Not sure about the purpose of the two top pieces, but it looks like they provide some vibration or stability support to the radiator and hydraulic oil cooler. I'll check with the local dealer when I go to pick up several parts I have been waiting on.

    It’s sheets not tape. It is flexible though.

    For key 27 I used weather striping with adhesive (peel & stick) from a big box building store. Key 7 goes over the radiator fill neck and under the hood. Key 8 goes on the oil cooler. The slits are for the hose from the oil cooler and vent hose from the shifter's mount

    You are correct, the foam is to force the air (pulled by the fan) through the radiator.

    Making progress...

    Picked up the new radiator Thursday and some other parts, including the manuals, we had been waiting on. Asked parts man about foam pieces...sure enough,they don't have any on hand and one is no longer available. Prices are a lot more reasonable than they first told me. Looking for substitute at least for the interim.
