4520R Fuel Filter

JonnyRed · May 25, 2018

Tractor has 100 hours on it (2 years old) and I am wondering if there is any action I need to take with emptying/cleaning the fuel filter.

Can someone walk me through the correct process? Main concern is getting air in the system and having an issue afterwards.

Might be overthinking it but thought I would ask.

Thanks

There's usually a bleed screw on the top of the filter housing. You can remove the filter or dump the bowl out to inspect, then run the lift pump with the bleed screw open until the air is bled out of the filter housing. You don't want to run the engine until the air is bled out as that will suck air into the injectors. On my 3725 there's a manual pump on the filter to help bleed the air but I think the 20 series has a different filter setup.

There should be something on this in the owner's manual or shop manual.

Here is a link for the service manual for the 20 Series. I downloaded and saved it while I was looking for the manuals for the F series ( 15 series) for my tractor. At the time I thought I would save as many manuals as I could so if they remove them from the Internet, it could still be available. Ended up happening exactly like I thought.

The 10 and20 series have the same manual. Here are Wix filters that should work.

Wix filter 51334 is the filter for oil
Wix filter 51202 for the hydraulics.
Air filter Wix 46438.
Fuel filter Wix 33263
