I'm not sure if this is what You are looking for, or what You need...
But, if You go on Ebay and search HD Panhead Rigid Oil Filter Kit, You will find a Seller that has two of them for sale.
You will need to scroll down the page and will see the Filter Kits.
Each one is selling for $138.95 to make it easier for You to search.
I believe that in the 1st listing, if You look thru all the pictures that they are providing...
You will see a Page out of the Panhead Parts Manual with a Parts Breakdown, and the Parts Numbers.
You may have to zoom in on the Parts List to get a good squint at it.
If You may have or have access to a Panhead Parts Manual it is shown as Oil Filter Group.
Hope that this may help You a little.

 

QuoteYes, I installed and adjusted the preload on the lifters.  I plan to (one at a time) to disassemble, inspect and clean the other three lifters.  And whereas I have the rocker arms and pushrods out I will be looking at them and cleaning them.  I am only returning the one bad lifter to Feuling at their request as they warranted the one failed lifter.

As WFO Larry mentioned "too tight a fit between the plunger & lifter body". May just be a factory machining failure.  It's amazing that some micro debris or grime could pass through the lifter hole and squeeze such a tight tolerance between the plunger and lifter bore causing it to seize.

I had a Fueling lifter also do the same a few years ago.
Took all 4 back to them to check them out. One had enough contamination that it would stick sometimes. Their lifters are setup tight I was told, and to make sure I do the recommended oil changes!

My fault, still using the replacement lifters after 70K miles and just pulled them out last month to have a look, still looking good and put them back in. Gotta say, no charge and  Fueling is very good at customer service!

Quote from: kd on March 17, 2025, 06:46:35 PMUntil you confirm what that deposit is, I personally would be pulling the rocker shaft(s) and pushrod(s) and inspecting them and the head cavity for a similar substance. It all comes from the same gallery to the lifter feeds. Being careful not to let anything get away with well place white shop towels or the like will show deposits that leak out (if any).  Knowing there absolutely is a deposit in at least that one lifter, not following up would keep me awake at night. I would probably open up the other 3 lifters on a clean white paper towel for a similar inspection. IMO, At this point there is a risk of a reoccurrence that could take out the engine all together.  I personally would need to know before reassembling it.

Did you do the lifter installation?  If so did they all fit with similar drag / clearance?  Did you offer to send all four lifters to Fueling for inspection?

I've looked but not sure where else to look.....I have a side mount/aux oil filter I put on when I did this 1980 shovel many years ago.....I'm guessing it's a Custom Chrome assy or similar. I put this filter on it for a couple of reasons....I thought it looked cool...and I had a Gary Bang, if I remember correctly, king-queen seat setup with a lighted tombstone taillight built into the wood insert I trimmed it out with and was a pain to take all apart to remove the seat and change the factory filter(1980 oil tank)This gasket set has what looks like the right top gasket for the canister but I'm looking for the parts breakdown for it...or the stock side filter breakdown......if anyone here might have that or know where to look...Thanx

It's probably not visibly blocked because the conamination entered the lifter and played havok in there seizing the plunger. The deposit in the pics could have easily made it out past the more loose fitting pushrod cup. From your description of the black case sealer is a possibility.  If it did enter the lifter body, some may have made it out the top to the pushrod cup AND up the pushrod to the rocker to lube the shaft etc..

Thanks for expanding the image FSG. Looking deeper I see what the OP is referring to. Yes that would be some wear from the feed gerotor.

I also get new glasses next week. I'm half blind right now.     

I appreciate your response, thank you.... I went to your website and see you offer a 0.0002" oversized lifters.  It looks like Feuling is my only choice now due to the 0.00015" bore.  In previous builds I always used your 2313SE. 

The Failed Feuling lifter side oil feed hole is clean.  No evidence of it being blocked or grime.
