Donut for air intake

Dwellonroof · Feb 20, 2022

Anyone with information or ideas about replacement donut for this setup?

The hood closes on it to make a seal but I can’t find anything like it tried to google it but no go.
It has2” center opening and about 4-1/2 outside and 1” thick.
It’s for my 425 Allmand backhoe.

Does it have a Kubota engine like most do? Then look for the air filter for that engine.

To me, it looks just like the air intake canister for a Yanmar or John Deere or Ford 1000 Series tractor.

I have the filter but need the donut where the hood meets the canister.

That donut just limits the amount of warm air coming from the engine compartment and probably still does a fair job at that. All the cumbustion air appears to still go through the filter. It never actually sealed the air flow. I might look for a new one, but I would also keep operating with no worries until I found one. If all else fails, glue an appropriate thickness of memory foam on top of it to fill the gaps.

HA, just re-read your posting, you want the donut seal from the hood to the intake canister. My bad.

Since you know the measurements, all you need it a chunk of the high temp foam to make your own.
