Wrong oil filter - Engine threw a rod

Richardl555 · Dec 2, 2004

Hi Everyone,
I am new to this forum. I own a NewHolland L-555 Deluxe Skid-Steer (Kabota V-1902B engine). A week ago I went down to a NewHolland dealer and purchased a couple of oil filters and oil for the machine. While changing the oil I noticed that the filter they had given me fit properly but was about 2" longer than the one I was replacing. At the time I figured "The bigger the oil filter, the better". I fired the machine up the following week to use it and after very little work, I let it idle for a few minutes while I get something and POW, the engine clanked to a stop. I could turn the crankshaft about 300 degrees in either direction, but it would just freeze at the same point. I had it deliverd to the same dealer I bought the filers from and they said that I had thrown a rod. My question is...did the increased capacity of the new filter cause enough of a drop in the oil pressure to blow the engine? I have verified that the dealership DID sell me the wrong filter but I also feel a certain amount of responsibility in that I noticed the size of the new filter was larger. Any input would be greatly appreciated.
Thanks very much,

Rather than low flow due to increased capacity the problem likely is reduced or no flow due to the design of the different filter.

Or, the rod problem may be totally unrelated to the oil filter.

OUCH!

Compare the filter gaskets and perforations on the face of the filter. It could be that a size mismatch in the business end of the filter blocked off the oil flow. Good luck!

Richard don't beat yourself up too bad as many members of the TBN site including myself have noticed that recent replacement filters for out newer tractors are coming in different sizes that the original filters so physical size comparison alone is not the answer.

That said, you purchased your filters from a reputable dealer and they admitted supplying the wrong oil filter to you. I would think there might be some responsibility by the dealer to help make this unfortunate incident go away.

Sorry you had this problem. /forums/images/graemlins/frown.gif

When I purchased oil filters for my new Tacoma the Toyota parts department gave me a choice between two filters one 2" longer than the other. I asked what the difference was between the two and the answer I got was the longer one offered more filter area or it would hold more dirt before becoming plugged up.

You reasoning about the longer filter seems accurite. It's hard to believe there would be a significant pressure drop across any two different oil filters. The flow of oil through the filter should be in the same direction for both.

Hopefully they agree to share some of the cost of repair.

Assuming that it was just a larger filter, and no other problems with valving, or covered up ports, other than perhaps a fraction of a second longer for the system to presurize, the oil pressure should be exactly the same as with the other filter.. there should be no drop. ( assuming it was a compatible filter with the same flow characteristics. )

I've seen lots of cases where 2 filters of a different size fit a given application depending on whether there is ac or not.

My wifes vehicle comes back from a dealer oil change with a filter at least an inch longer than what is spec'd at auto parts store.

Ask your dealer to take a new filter with the same number on it as your suspect filter and put on a new skidsteer of his that has your old filter on it. /forums/images/graemlins/wink.gif

I really don't think the filter caused your problem. If the filter was larger or smaller in diameter then maybe. But I would have thought you would have seen no oil pressure before any damage. It is really tough to say.

I remember about two years ago my wife had our suburban oil changed. The company that changed it called me frantically wondering where my wife was going after they changed the oil. I said I didn't know but why, they said the must have put a defective oil filter on because it was leaking really fast. They tried following her by the oil stream on the street but couldn't catch up to her. Well luckily she came straight to my office, she was concerned because the oil light came on a block away from my office so she stopped in. The company that changed the oil came right over and replaced the filter. I looked at the defective one they took off. It was just missing the gasket. I told the guy there was nothing wrong with the filter, it was just missing the gasket and then asked him what kind of mechanics did he have anyway. We have not gone back.

It's doubtful that the filter had anything to do with the rod blowing. You did have oil pressure showing on the gauge, or at least the light was out, right? If you look at the design of a spin on oil filter you'll see that as long as the gasket hits where its supposed to and it doesn't fall off the mounting stud it's going to work. You'll know if it doesn't fit from the large puddle of oil that immediately forms under the vehicle on startup. /forums/images/graemlins/blush.gif Chevy gasoline engines used on medium duty trucks hold 2 quarts and the oiling system is the same as the one on cars. The oil only leaves the filter as quick as it's pumped in and all oil filters are designed for the lowest Delta P (pressure drop) that the designer can get away with. It takes power to pump oil, why waste it? The only real difference in oil filters, besides the obvious, is that filters designed for being installed with the mounting face facing downward have a check valve inside to keep the filter from draining after shut down. If you install a filter without the check valve it probably takes 3 seconds or so for the oil pump to fill the filter. When you change the oil you have the same lag time. There has never been an engine built that would blow up from no oil pressure in that short of time in less the engine was fixin' to blow anyway. /forums/images/graemlins/smirk.gif The New Holland filters I use on my TN 65 will leak down overnight and they have the check valve. The only problem with that is that I like to check the oil before start up and the filter draining down pushes the oil level up way over the full mark. /forums/images/graemlins/mad.gif

You need to look in the engine to see if oil starvation caused the rod to fail. If you can still turn the engine by hand I kind of doubt that lack of oil was the problem. All of the bearings would have been lacking oil and the engine would most likely have locked up. Did you notice low pressure on the gauge or an indicator light? These engines are often equipped with a low oil pressure shut down as well.
