Screw the filter on to the mounting bolt's threads.

That’s what I do also.

Thread it through the smaller hole on the bottom. Keeps the filter in place on the bolt when you reinstall.
Why is there never enough time to do the job right, but always enough time to do it over. :?:

Frams have been like this for several years and it's always the lower small hole. I carefully thread the hold down bolt in through the lower hole first carefully "wobbling" the unthreaded portion of the bolt until the gap opens up just enough to let the bolt pass through. The first time it happened to me it was all together.Had a heck of a time getting it apart since the filter just spun so I could not pull the bolt out to get the cover and filter out.

First:
I merged the two oil filter threadsbecause they refer to the same subject. There is no use everybody answering two different threads. That could lead to some confusion.

Second:
Have you guys referred to your owners manual when you installed your filters. The holes are made that way for a reason. When you put the top of the filter (large hole) on the bolt you should screw the threads into the bottom end (small hole). when you install the top, gaskets, bolt and filter, the top will pull the filter down into it's proper position. Although that part is not spelled out, that is what happens. Do not ream out any of the filter holes. They are that size for a reason. Once the filter is tightened down the bolt will pass through the bottom hole and seal it. Reaming the bottom hole only causes a small opening for dirty oil to pass through. if that happens you might as well not even have a filter.

thanks barnyard but my problem was that both holes were the same size I had to ream the top hole to get the bolt in and then screw it through the bottom hole.

I guess it doesn't matter then because for the last 40+ years the bolt has been falling thru the available filters anyway. :wink: Are these even full flow filters anyway? Many vehicles from those days were not full systems, VW made millions of cars without filters at all.

Hi,
Oil going through the engine oil filter goes out the hole in the bottom end of the cover bolt, and down to the oil pan.
The engine isn't like some engines where all the oil from the oil pump goes through the oil filter first, before going to the engine parts.

Below are pages from the Cub service manual, showing the oil system.
The oil filter is on the right on the 1st page.

It tells about the oil filter in the Description, on the right side of the page below.

All the filters I have used, Fram and Wix, never let the bolt drop straight through. I have always had to thread the bolt through the bottom hole. I figured that is why the bolt had a shoulder just up from the threads.

Obviously not my experience. I can't even see how you can even get the whole assembly up and out of it's canister when it's all together. Ford uses a much better system- it has grommets that are mounted into the filter at each end rather than rely on metal to metal contact
