Cummins Onan 10kw generator-Air filter

Can anyone impart a little wisdom on how to change the Air Filter on the 10k, Spec E Cummins Onan generator ?? Does the coolant tank really have to be moved ?? It is the 10 HDKCA11506 E

Thanks !!

There are two bolts holding the tank, if it is like my 12.5k generator and I think it is. Take the three bolts out that hold the tank and you should have enough room to get the filter out and back in without disconnecting any hoses.

The air filter housing is located right behind the coolant reservoir. The most feasible air filter replacement is to remove the coolant reservoir versus removing the entire top panel.

It's a lot easier than it sounds. Just be careful that you don't spill anything out of the reservoir as you move the neck out of the hole. The whole job shouldn't take more than 10 minutes start to finish.

It's in section 3-5 of the operator's manual. If you don't have it or can't find it, send me a PM

I also have the 12.5 k gen. I thought the same thing when I went do do the service. But it's actually super easy.. Just 3 bolts
And you can access the filter fine....

Engineering at its finest. Wait till you change the fuel filter on the newer 12.5kw
