Broke 2 Oil filter wrenches

[sem389]

My first fluid change on my DK4510 was similar. Broke a new strap wrench, a different on slipped. Finally went and got a pair of Channellock filter pliers and that was that.

That’s what I used too

Actually, not. The filters are installed prior to final chassis paint and the painted filter locks it on. Real common. I never bother with a filter wrench, put a pan under the filter, take a long handled alignment punch, drive it through the body and lever it off. Been doing it that way on every new tractor I've purchased for years now. Once you change it, the next one will come off easily. The paint is holding it on, nothing else.

I discovered those were the only thing that could reach in past the rats-nest of loader hoses to loosen the fuel filter bowl ring on my Yanmar.

I to own a filter wrench similar but it's not Channelock, I can't imagine a chain wrench slipping, if you set it up near where it's screwed on it will bite, I use a cheater with that long handle of a chain wrench, come or blead.

Maybe that works on Deeres, and if you have room for a strap style wrench you are lucky.

The problem on some Kubotas is that there isn't enough room to slide a chain wrench or strap wrench onto the the HST filters. The filters are in a recess with only a few inches protruding. You can't use large pliers for the same reason. There just is not enough room to grab and turn.

Usually that's not a problem unless the filter is put on too tightly or stuck for some reason.

The charge filters are always a bear if installed correctly.

I'd like a torque spec. Can't find one in the manual

My idiot ex wife wanted a Saab. She thought they looked cool. It drove all right, could go like a bat out of hell.
I had to do the water pump.
To access the water pump, required I drop the tranny and lift the engine. Yah, for the water pump.
It would only accept one model of Continental tires ( the most expensive model).

I got rid of that car with the witch.

Some years ago my wife wanted a Saab. She like more uncommon cars. We had to drive quite far to demo it. Took my first Toyota Tundra, maybe a 2001 (??). We immediately gave up on the Saab after realizing the Tundra rode better than the Saab and was nicer to drive. A reflection of both vehicles.

Perhaps this has already been discussed since I have not read the entire thread. There is a lot of talk about what to look for when buying a tractor, reliability, quality, weight, loader capacities, comfort, dealer quality, etc. I don't recall any mention of how easy it will be to maintain and work on. Am adding this to my list. Would not be able to take filters off on a prospective new tractor to assess difficulty to remove but certainly could look at how easy access would be, for example

Just picked up a strap filter tool and the channel lock #215 filter wrench. On a ck4010 hst, the strap worked to loosen the engine filter, and the channel lock wrench was able to get hold of both hydraulic filters to break those loose. There was enough room at the base of all these to get a firm grip and fairly easily first time off get them to rotate.

Ah, yes. At first glance it seems that a torque spec would be handy, but that is probably not the way to go. Though it is easy to see how that conclusion comes about when the original filters put on by the manufacturers are universally way too tight and in some cases appear to be stuck with either paint of adhesives.
Once you get that original one off, you can improve how the replacement filter will fit in the future.

The way replacement filters are designed to seal is not by thread compression (torque) - but by how much a rubber ring is compressed when tightening the threads a certain amount from first contact. A clean surface with some oil on the O ring helps, a light smear of the right type of grease is even better.

If you are the curious type, measure the thread pitch of the mount and compare that with the height of the uncompressed rubber ring. That will give an idea of how much compression that the replacement filter is designed for. That is probably a better way to look at it and a more useful spec. than torque.

measure the thread pitch of the mount and compare that with the height of the uncompressed rubber ring. That will give an idea of how much compression that the replacement filter is designed for.

So the filter spec of 'snug then 3/4 turn' (etc) is a shorthand way of describing how much compression is intended. No need for a torque spec.
