Air cleaner gasket

The new air cleaner I bought doesn't have a gasket on the small end like the one I'm replacing. Should I care? Seems better to have one there but what do I know

There's also a small hole in the old one.

New filter is a Donaldson, old one was a Napa
Old filter was installed by PO.

Thanks 👍

I would think you need the gasket and the hole is for the air cleaner indicator,

My air cleaner indicator is attached to the lid on the outside of the filter

They all have the indicator on the outside..the hole in the filter measures the amount of vacuum to indicate "stuffed" or "clear"

Ok, but the new one doesn't have it so...🤷

Am I suppose to drill a hole?

I don't think the filter minder would work without the gasket on the small end of the filter (and the hole obviously).

Crazy, you would think if I ordered a Donaldson filter it would be OEM and have the proper setup

Well I can easily drill a hole and transfer the old gasket and attach it with some sort of gasket maker

You might want to punch a hole instead of drilling

Is your new air filter a Donaldson P14- 8043? Mine comes with the small hole and gasket on the small end. If you look on the filter can here should be a tag that identifies the correct filter number. If you are matching up one someone else installed it may be the wrong filter.

Punch a hole of the same size same location. Take gasket off old filter, clean, silicone or glue to new air filter.

Thats exactly what I did...filter was exactly the same size so just modified it and I'm ready to go 👍

Does your new filter have the same mesh screen on the inside of the air filter? If so good to go..  If not, order a new one as soon as able.  Another member had a filter failure in the past due to no mesh inside, catastrophic damage as a result.

I actually didn't pay attention to the inside, the one I installed is the Donaldson P150694 but after a quick search no info on if there is a screen on the inside. Guess I'll have to pull it out in the morning and check. If it doesn't guess i'll throw the old one back in for this trip and order something else.

Dylan, looks like you got it handled. But here is a little longer discussion with photos, last post shows what I ended up with.  FYI for next time or anyone else searching in the future. Donaldson Air Filter

Is this hole bypassing the filter material and letting dirty air into the engine?  I first thought the hole was to have bolt going through to hold filter in place. In looking at picture it shows the hole off to the side 

If not mistaken somewhere I read is to don't keep opening the cover for fear of getting dirt in engine. Maybe I dreamed this thought up.

Many discussions about this very subject. The hole enables the restriction gauge to measure the differential cause by a plugged filter. The gasket must be in place to provide a seal for it and housing is designed for the additional length. So yes swap gasket and poke a hole in the end. Size is not critical. The preferred Blue media filters are no longer available. PLEASE  also verify your vacuator valve is soft and viable. They age and get hard , loose in the hole. Water can be drawn into the filter at this point if they are in poor condition. Ive seen one with a squirrel that had gone in and died after getting stuck do to it being missing. If you were to drive threw deep water it would directly suck water into the filter housing. If its failing, remove and tape over as very very temp repair.

Just called Donaldson and they confirmed that the P150694 does have the metal mesh on the inside...trying to get on the road and didn't want to pull it out so a quick call confirmed it. 👍

I used a Donaldson Blue for a Cummins on our Detroit. It didn't have a gasket but I used a razor blade to carefully remove the old one and glue it to the Donaldson. I then used an ice pick and a quick hit with the palm of my hand to make the hole. As a member above posted, don't drill a hole, punch it.

The Donaldson is not just better material but has much better wire mesh on the inside and outside plus it's glued in a bunch of places. First rate construction. Most GVs suck up anything on the road and our old one was crushed by water that came off the rear tires. A damp filter will also register much higher restriction on the filter minder. Lots of sticks, dirt, rocks, etc in the canister also.

Donaldson makes several different filters with the same dimensions, some plain, some with the gasket and some with the gasket and filter minder hole, all with different part numbers. Ours has the wire mesh on both the outside and inside and designed to filter air from the outside to the inside. 

The old filter that was crushed was a Wix.

For any air filter-- just because the dimensions are the same as the old one does NOT, repeat NOT necessarily mean it is designed for your application.

Depending on whether air flow is from the outside to inside or inside to outside, there has to be wire mesh to support the "vacuum"/engine side of the filter.

So, if air flow is from outside to inside, there has to be wire mesh on the inside.

Yes, some filters have wire mesh on both sides so they can be used in more applications.

All the filters I have used for the Detroit, the Donaldson, Wix, etc have had the wire on both inside and outside. The Wix that was crushed in the photo had wire on both sides, just inferior construction and was the listed filter for the Foretravel U300/Detroit.

To also bring up about the importance of a good air filter on here is a thread which I am sure Michelle will be able to find. Someone was driving trough snow.  The snow went up against the filter and melted. Making the filter wet. There was no inside mesh so filter collapse.  Engine ended up being dusted and caused the owner a several coach bucks.
