I tried searching but didnt find anything. I have a 1952 F6 with the 226 flat head. I bought a spin on conversion filter kit from NPD but after I pulled the cartridge housing I find that it isnt going to work. Any ideas? Thanks

 

My first guess would be it's for a V8. I haven't seen any spin-on kits for the 226.

 

Could be but listing said ALL 48-56 engines with canister....

 

Well, maybe, but I think the "canister" for the V8 is somewhat different from the 226 canister. I know the mount is totally different.

 

Most spin-on's have anti-drainback valves in them, so I don't see how they could work on a bypass filtering system.

I think Joe is right, it's for the OHV V8's..

 

Yeah, I dont see this working... Back to the canister. Hope the gasket is good to go back on the block. Thanks for the reply.

 

I believe the difference is that the V8 engine uses tubing and hoses for the supply and discharge from the canister, and the 6 cyl. supply and discharge is integral with the mounting bracket. The spin-on filter will work fine in the partial-flow application, but it won't be used in it's fullest capacity as a full-flow filter. I am going to look into this down the road for my 254 because I want the convenience and cleanliness. It should not be difficult to fab a bracket to mount a remote spin-on filter (I've done this on marine engines) and tap the existing supply and discharge ports for NPT.

 

The elements in a bypass filter are much finer than for a full-flow. The spin-on full flow will obviously do "some" good, but not as well as a bypass element. From the Ford Barn:

A bypass filter like the original will remove finer particles than a "full flow" type filter

Most ring and bearing wear is caused by particles under 20 microns

a bypass filter will remove 98% of 2 micron sized particles

A full flow filter most likely will open the internal bypass valve on cold startup and not filter till the oil thins some, then ---
40% at 10 microns
60% at 20 microns
90% at30 microns
97% at 40 microns
87% capture rate for single pass ----
the "full flow" filter has to be a compromise between filtering and flow, the ideal setup would be a combination of full flow and bypass

The million mile Mercedes only had a bypass filter

 

It's a moot point for me anyway because I change oil and filters by analysis (except for the motorcycle, lawnmower, chipper-shredder, leaf blower, and lawn tractor), which is far more accurate regardless of filter type.

 

Listing is wrong...

There is only one Spin-On oil filter adapter kit (B7A-6882-A), but it's for OHV I-6's and V8's only .. not for flatheads.
