Hd 63805-48 oil filter housing-in need of repair

Purchase a good one.

It is the hole in the oil filter housing that is stripped out, and the oil tank fitting measures just over 1/2 inch, so I think the NPT would be 1/4. I put an oil tank fitting in the housing to show how easy it drops in versus being screwed in. I think you are telling me to machine threads, something I have never done. If it is like a Time-sert, there is an external thread and an internal thread on the insert, the tapped hole for the external thread of the insert would be larger than the 1/4 oil tank fitting and a little larger than the hogged out hole in the oil filter housing, while the internal thread of the insert would be the 1/4 NPT tapered thread and the insert is basically swedged in place with a driver, after cutting the threads with a tap. I use that process fairly often and have multiple size kits from Time-sert, but cannot think how I'd make my own insert, sorry.

The thread you're trying to repair is 1/8 npt. You can make an insert to accomplish that. Done properly, it will hardly be noticed. You could alternatively tap for a larger pipe thread and use a reducer, but that will be easily seen.

I do, a Smithy Mill Drill Lathe, though, I must admit I am very good at using it. What do you have in mind?

Do you have a lathe?

Part of what he brought to me is an oil filter housing and canister. The housing has the number 63805-48 and a number 9 or 6 stamped inside. I believe this to be a true 1948 part and worth saving. The issue is that the internal (female) threads that allows the housing to attach to the tank with the permanent fitting is hogged out. There are threads, but I'm guessing that was an insert of some kind because I found part of the insert inside. The cause may be because the female threaded portion of the housing is off-center. I was able to get the housing on, but never able to adjust it or make it tight. The half-moon mark on the housing is from where I ran the housing in tight to the tank and the housing was pointing straight up, causing me to inspect it. I use Time-Serts, but cannot find one of theirs that is the correct size insert. I've checked many sources, and do not come up with an insert.

Any help would be most appreciated. It may be that this could be repaired without an insert (welding?), but not by me.

Thank you for your help.
