My donor '72 1500 has a spin on filter conversion. It has a red filter with "CROSLAND 595, leave adapter, replacement use 670" painted on it. A few years ago when I bought the car I changed the oil in it before I fired up the motor to check it out. I could not find a replacement filter at the time, but then again I didn't have access to all of you guys. Any suggestions? Thanx!
 
I'm confused, at least by your terminology. All Spitfires used a spin-on filter. There were any number of filters that apparently came with the male thread, but there iss also a readily available adaptor that one then reuses with a Motorcraft FL-1A, AC PF-13, Fram PH-16 or other very common filter. The adaptor is 5/8 to 3/4, and is available from Spitbits and probably many other vendors. (Your local NAPA store might even have one?)
 
I guess I'm the one who is confused here Andy. For some reason I was thinking it was a conversion from a canister style filter. I looked at one the Heralds and it has the same spin on filter as my Spit. So what was the original filter # then? Do I have to buy an adapter from Spitbits? /bcforum/images/%%GRAEMLIN_URL%%/crazyeyes.gif
 
The only "oddball" is the older 803cc and 948cc Standard (and Triumph 10/early Herald) engines. They also had a spin-on filter, but it was of a different type (bypass), smaller and now generally unavailable new. That same filter was also used on some small Austin and Morris engines, and some folks have started manufacturing adaptors for those engines to accept modern and readily available spin-on filters.

I don't know if I've ever seen an "original" filter for the 1147cc and larger Triumph engines, but I think the "original" spec. was for a filter with the male threaded end. The adaptor, though, is the way to go, since it makes local replacement of a filter (with a Fram PH-16, AC PF-13, Ford FL-1A or other equivalent as used on a host of cars) much, much easier!

Did that make things any clearer? Probably not! /bcforum/images/%%GRAEMLIN_URL%%/confused.gif
 
The threaded nipple you screw the filter onto is almost always a 3/4-16. This is an adapter, as the OEM was not this thread size. Virtually every Spitfire in the US has been converted to this, at it's first oil change.

There's literally hundreds of filter choices you can go with that will fit a Spitfire. As well others. This thread size is very popular with car manufacturers.

You can cross reference and index to your hearts content at both the Balwdin and Wix filter sites. Wix cross references better, while Baldwin gives you much more specific filter information in a book form.

Myself, I'm running a 3614 filter, which fits my truck, the volvo and the Spitfire, meeting the requirements for all of them (pressure relief, flow, seating, etc).
 
Thanx guys, clear as mud! I went up to my local NAPA and should have one today. It was a different # than what was called for at the other stores... We'll see!
 
I just happened across some information I'd compiled awhile back and stashed away, regarding the adaptor for Spitfire oil filters (prices may have changed in the past year or so):

From <www.spitbits.com>
Part number SLP178; price $4.25

From <www.the-roadster-factory.com>
Part number SLP178; price $2.60

From <www.mossmotors.com>
Part number 833-455; price $4.95

It's basically a 5/8" to 3/4" adaptor.

Hope this helps someone! /bcforum/images/%%GRAEMLIN_URL%%/smile.gif
