napa oil filter

[tomstractor]

Went to install my Baldwin oil filter and found out that the hole on one end was smaller than the other end. It fits tight on the bolt.
Never noticed that before. Which end is up and why?

[Dale Finch]

It will only fit one direction. And yes, it is a tight fit!

[Don McCombs]

The bolt enters the filter through the larger hole and exits through the smaller hole.

I went to install a new oil filter on my 1959 lowboy that I bought from Napa and I had to ream the top hole for the bolt to fit through . any body else have this problem.

[Bob McCarty]

Did you try turning the filter over? The bottom hole is smaller than the top one.

[Dale Finch]

As Bob said, one hole is smaller than the other...large on top and small on bottom. I just installed one a couple weeks ago, and did need to press quite hard to get the bolt to go through the bottom hole.

I'm fairly confident that you altered the functionality of the filter. My suggestion (worth what you paid for it) is to replace the oil filter.

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

I've found a lot of things to buy at NAPA but never found a cub for sale there!

[kully560]

yes I tried both sides and just had to ream less than a 1/16" for the bolt to go through . If I tried to force it I would have bent the top of the filter in.

There was a problem with Wix filters having an incorrect hole diameter. Wix does make the Napa filter.

Hi all,
First, we want to thank you for bringing this to our attention. As you’ve all noted, we are selling a Wix filter and have been for some time. It does seem that many of those that Wix sent recently have the incorrect hole diameter. I want to apologize for anyone that felt their problem wasn’t understood properly by our staff here. We strive to take product issues very seriously and I escalated this situation to the General Manager and the President to ensure we are communicating at all levels of our staffing these type of product issues and are making it right and not hassling about a return.

Currently, we have a staff member from our Quality Control team sorting through all of the filters on the shelf and testing them with the bolts from the Farmall Cub to ensure proper fit. Right now, the Bad pile is larger than the Good pile, but we do have confirmed good ones to ship out if anyone is still in need.

We also read what you wrote in regards to the overall filter diameter. Dan Steiner is having our purchasing team research other available filters and we may be making a switch from the Wix filter because of that 1/4” overall diameter difference you identified. However we do like the fact that Wix encapsulates their cartridge filters with steel which is why we choose them over other less expensive filters.

I want to make sure that you all have an open line of communication at Steiner Tractor Parts. We have learned so much from the group of fine folks on this forum, your experience and knowledge are vital to this hobby and I thank you for all the work you do to promote tractor restoration and especially to help out newbies. Your forum is a wonderful place for guys to gain knowledge and insight into their tractor and that includes our own team here at Steiner!

Please feel free to reach out to me directly if you ever hit any road blocks at Steiner Tractor Parts. I’ve posted here before and wish I had more time to be more active. My name is Elizabeth Whiting. Technically, my primary responsibility at Steiner these days is our website, SteinerTractor.com and also our tractor club outreach program (any tractor club guys, hit me up for program details this year). However, I am willing and able to get you in touch with whomever you need based on your request if I cannot assist myself. I created a special email alias for you guys to use, farmallcub@steinertractor.com. This will put you directly into my email inbox. I’ve worked here for 18 years and am glad to serve as a point of contact for this group. Also, if you prefer a bit more anonymity, we also accept any and all customer feedback at customerexperience@steinertractor.com. I do not personally monitor or receive those emails like I do the one above, but emails to that address should also be routed to the proper parties. If there are threads here that could use Steiner input, please feel free to send me the links.

Thank you again for all of the research and explanations and pictures in this thread. It is very helpful.

To answer your original question: no, I’ve never had a NAPA filter have that issue. Perhaps it’s a different supplier or a filter that didn’t get properly punched on the assembly line. If you only made it large enough so the bolt fits snug, then the filter should be fine. If there’s room enough to wiggle the bolt, then oil can bypass the filter, as you probably know.

Thanks for the”heads up”. It’ll be interesting to see if anyone else has this experience with NAPA filters in the future.

[kully560]

sorry Stanton , I just my garage and it was a wix filter not a napa filter my mistake. I still have 1 more filter on the shelf that I bought several years ago and will use it up and then look for a different brand .

I just installed a NAPA filter this week and had to ream the top hole also. I thought they had the wrong filter in the box, but it was exactly like the one I took out. It is a tight fit.

[kully560]

yes that is what I am talking about the top hole needed to be reamed a little. but I purchased these filters about 2-3 years ago. I buy 3- 6 at a time and still I have 1 left over and the next time I will need to ream again. I am going back to baldwin filters as they are a direct fit.
