difficulty removing old oil filter

[bizzaro]

"Moving the handle of a ratchet wrench 180º is about as simple as it gets, and not particularly dependent on grip strength."


Of course you mean 90 degrees. Just sayin?  I usually go a bit more, maybe 120.

There are a ton of filters that fit K bikes that cost less than $7.  I use the AC Delco PF-53 or it's Carquest equivalent(that's the store in my town) for $6.  Both of these filters are strong enough to handle the wrench I use on them for removal.

When you install the filter spin it on with your fingers.  Make sure the body is dry as well as your fingertips.  Wipe up all the old oil around the hole and put some on the gasket.  Spin it until you can't spin it anymore.  Then get your wrench and give it another 1/4 turn.  These are the instruction from the people who make the filters and they are universal.
   
If you are using a wrench to spin the filter on you have no feel for when the gasket makes contact, and you will overtighten it every time.   I've installed and removed about 7-800 filters over the past 10 years on boats in some pretty ugly places and never used a wrench.  Not one of them ever leaked.  You have to be able to feel the gasket make contact, I can't overemphasize that.

+1 on the pf53, my choice for the last 150k or so.  and overtightening can squish the gasket out of place with very bad consequences. I have never used a wrench to tighten a filter, if I can get a couple fingers on it I can get it tight enuf.

Am I missing something here? 
Tighten the new filter hand tight plus a quarter turn...  It won't leak. How would you know if it leaked any way, it's incased in a cavity inside the motor that is sealed up with an O-Ring and three allen head bolts.
I'd be more concerned with the drain plug leaking then the oil filter.

in the interest of preserving BBY's good name, I've never heard of filters being graded by the quality of their sheet metal.  Glue, relief valve, filtering media and density.  Fram seem to take the blunt of online abuse for cheaply made filters.  So long as they don't leak, flake off (Fram's grippy stuff) blow out or get stuck on I'm ok with just about any of them.  I have a selection of filter wrenches due to my inclination to use whatever fits, always been able to find one that works.  :riding:

Of which tools are in the selection of tools you say you have that work in this situation?

No. I meant 180º after contact. AKA 1/2 a full rotation.

Never had any trouble with Mann MW712's. Supposedly one of the original suppliers.

Mann are high quality filters.  I use them on my porsche for both fuel and oil.

There is a hugh difference in the filtering capacity of oil filter manufacturers.  One of my car clubs did an experiment and bought a filter from each manufacturer for a specific vehicle.  These filters were ran on the vehicle and then dissected.  We cut the filters in half and found a hugh difference in the qualities and materials of construction in them.  Some of the filters simply collapsed their paper elements and the oil never got filtered and the end stage of use.  As probably you are aware, oil filters are by pass flow, and if they plug up the oil simply is rerouted directly back to engine with no filtration.  I remember Fram being one of those where the elements had collapsed though there were others.   Wix and Mann were the best quality filters which we tested. 


Regarding the good name of BBY, when I opened the box of the 6 filter oil change kit I purchased, I received  6 filters, 6 oil plug washers, and only one o ring for the oil filter cover.  I guess that means the one o ring is good for 5 more oil changes?

It varies, but 6 is ballpark. Incidentally, there's no reason to unscrew the drain plug if you're changing the filter.  Not too messy draining the oil through the filter access plate if you're careful

I agree with that.  I hand tighten only.  In fact on some vehicles where I have good access to oil filter I also remove with my hand without need for filter wrench using a rag to cover for heat insulation.

Had my Brick a long time. I bought lots of OEM filters two to three at a time which kept me out of trouble. I was getting them for a good price from a non dealer. When I ran out I went back to where I had got them from and he had a different brand. I tried to get a local supplier of Mahle filters but I couldn't find a supplier. I then got onto a local supply of Mann filters and have been using them ever since. They are a lot dearer than others but I would rather spend a bit more and be sure of the quality. I don't drink coffee so what I save on latte and cappuccino I put into filters. And I think I'm still ahead money wise. :dunno

Using an o ring over 5 times in a use as vital as for a seal maintaining the oil in an engine?  Hard to believe......

[Chaos]

I don't think I've changed my o ring more than 4 or 5 times in 32 years.  Once I had it leak but it was pretty obvious as soon as I put oil in it.  You can tell when the ring starts to flatten out.

The oil flow design would take into account the pressure exerted by the resistance of the filter. If oil was to leak past the filter gasket, oil pressure throughout the system might decrease (I would think) because now oil can find a less resistive path.  That could have consequences for the lubrication and cooling in the engine.

What would the oil pressure switch be doing?

the oil pressure switch come on somewhere around 5-8 psi? not really sure.  The only blown k75 engine I've ever seen that was when the owner accidentally missed that the sealing ring from the old filter was stuck to the block and put a new filter on top of it.  It blew out on the highway, by the time he noticed the red light and heard funny noises that motor was toast.

One thing it does when oil pressure drops in a Brick is activate the low oil pressure light in the instrument cluster. The bike's operator should shutdown the engine then try to determine the cause. In some vehicles the oil switch signal might also trigger an automatic engine shutdown to prevent severe damage.

Tightening an oil filter is a tactile task. It doesn't matter whether it is done by hand or using wrench. The mechanic needs to be aware of when the filter gasket contacts the mounting flange then snugs it after that. Some manufacturers or manuals have suggested one-half to three-quarters of a full rotation; some have suggested one-quarter rotation; some have suggested just hand-tightening which, of course, would depend upon the strength of the hand that is tightening the filter and the awareness of the hand's operator.

If a mechanic is distracted, is unable to follow instructions, or is unable to believe valid instructions for one reason or another, moaning and gnashing of teeth by somebody somewhere is the likely outcome.

Yep,yep and yep. Correctly so. Engine management will activate. Bricks are  well designed.

If I don't shut down my bike's engine when the low pressure light comes on because of a pressure drop, nothing else will except a spun bearing or thrown rod.
