Oil Filter Cartridge 3.5 MKV

[ptelivuo (Pekka Telivuo)]

Hi all,

I checked the parts numbers and details from the Spare Parts Catalogues.

It would appear that there were only long(ish) cartreidges or “elements” as Jaguar / SS Cars called them on all six cylinder cars.

Pre-war and early post-war cars used an earlier type, but from 1947 when LHD production first began the Tecalemit filter was always the same throughout MKIV and MKV production: FG.2306.

For whatever reason my oil filter housing says: FG.2312, which according to GB Dönni’s e-bay webshop was the OEM oil filter for the six cylinder SS1’s.

https://www.ebay.de/str/jaguarclassic?_trksid=p2047675.l2563

So my guess is that in my case, as the engine was replaced by Hornburg in Hollywood, LA, with a LHD MKIV 3 1/2 Litre engine, that had the separate oil filter assembly and only the Relief Valve Housing on the cylinder block, they used an Oil Filter Housing that fit and was available, and it happened to be Tecalemit FG.2312 from possibly an SS1 or spare parts stock for an SS1 or some other British car that used that one instead of the slightly longer FG.2306.

And thanks Roger, I sent you e-mail about the part numbers.

I would need at least the Relief Valve Body C.1088/C.

But possibly also a suitable (long) Canister C.1089/A, if anyone knows a good source for one?

I’ll ask Worcester Classic Spares of course as well.

Cheers

Is yours like this perhaps?

This is for L and M series engines.

I was thinking SS1 did not have an oil filter?

Hi Rob,

Nope, but the “element” looks about the same length.

That FG.2312 reference is from GB Dönni, surprisingly few hits with google, and that’s what it says on the brass plate on my Oil Filter Housing.

I did post pics of it earlier.

And now I modified the broken Relief Valve Body so it will not give relief, but should not leak much either. i have now 10W-40 semi synthetic oil in there, so I am pretty sure there is no risk whatsoever of ”over pressure” or oil pressure above 60lbs at 2.500rpm.

Cheers!

Hi all,

I got a Relieve Valve Body C.1088/C from @Roger_McWilliams and I have now made measurements and a 3D CAD model of it, plus I have made a modified version of it (slightly longer body to accept a modern seal as the original fibre seal is completely NLA, C.1710 Washer (Fibre) between Relief Valve and Housing. The original washer is 1.5mm thick and a modern substitute I was able to get is 2.5mm thick. I am not sure how well it will seal, but it feels really tight and has a rubber double “lip” inside metal casing and is intended for hydraylic systems so I think it should be good.

I can e-mail if someone wants the file (please state in which format, SAT, STEP etc.) and in case I manage to get a workshop to use their CNC machine to mill some for me out of brass I can let you know in case someone would like a spare. AFAIK it’s about the same cost regardless if they make one, ten or twenty for me.

And I am thinking of having them make also new oil pump shafts as mine did survive ok, but I think the end that drives the oil pump has taken quite a hit (as it jumped) so I thought that as long as I have it at hand, why not also make a model and see if someone would make new ones at reasonable cost, as it is a very simple shaft after all.

BTW mine is from the 1947 MKIV engine #SL2199 so I read from an older Jag-Lovers Pre-XK thread (with Ed) that apparently the later MKV version did not have the oil groove in the bottom part anymore. Maybe that one got mine going with cold oil?

And what is that groove in the middle for? (the horizontal one, I know the vertical ones are the keyways for the two keys. Again for oil or something? (I think it sits just above the bush that has one 'thou clearance, just like the rocker shaft and rocker bushes.)

Cheers!

PS. I have never ever used inches and fractions in drawing before, PLUS I have worked as an architect, NOT engineer, so my dimensioning is probably very funny for mechanical engineers, BUT the 3D model and the dimensions should be pretty accurate.

Hello Pekka, Do you have the McMaster-Carr part # for the sealing ring? I’m guessing it is #337. Thanx, paul

[ptelivuo (Pekka Telivuo)]

Hi,

Sorry, I’m traveling at the moment and don’t have my laptop with me.

Also I originally got the part number from @Rob_Reilly maybe he knows.

Cheers!

[Rob_Reilly]

Yes, I got them from McMaster-Carr.
square section Buna-N o-ring size 337 part no. 4061T313 in a pack of 25 should last you awhile.
