Bedford mwd carb and air filter help

[Neilmwd]

Hello all!  Bit of advice needed please, i have a bedford here and have realised the air intake is off an old land rover and am now unsure if the carb is the correct one? If not can i get one? Also can anyone point me in the direction of the correct air filter parts? Any help appreciated 🙂

That carb is as fitted to the civilian spec Bedford engines, the oil filter is likewise. Neither are correct for a wartime military engine.

I see. What type of carb should be fitted? Thank you

[Richard Farrant]

You have a Zenith, correct one is a Solex 35RZFAIPO

The inlet manifold is a civilian spec as well as the mounting for the carb flange is different.

The correct carb is a Solex type 35RZFAIPO/C581/0. C581 should be stamped on the carb. That is the 35RZFAIPO specific to the MW, as it was also fitted to other Bedford’s such as the QL

The Solex one won't fit on your inlet manifold...

If the engine runs fine, I would suggest that you leave it as is.

Zenith carbs were fitted to post war Bedford 28HP engines, likwise the oil filter you have.  Your MW was probably re-engined at some point in its civillian life.

If you do decide to go back to the "war time spec", you will (at a minmum) need to get a new inlet manifold, new carb, new throttle linkage. I think that the exhaust manifold remained the same

Carb photos for reference...

Hi

Just noticed your coil is mounted in a different place usual ? Is this a "spare" as it doesn't seem to be connected

Cheers

Richard

[simon king]

I think that is the position for the screened coil used in the MWR FFW

[Rootes75]

If she runs fine I would probably leave it as is, at some point she has been modified and that just adds to her history in a way.

You would not know the difference if the bonnet is closed.

[simon king]

Given your MW is fitted with a non-original OY cab, I would be inclined to leave well alone. If it works, don’t fix it.

Does anyone have a photo of the propper inlet please? I found this but would a ql one be diffrent? Cheers.

[Neilmwd]

Hello would any one be able to help, would this Bedford manifold be any use to fit on my mwd? It says it’s from a ql. But is there that much difference? Thanks

[Richard Farrant]

Check the position of your oil filter mounting on the manifold and see if it matches the QL one.

[Richard Farrant]

Neil,

I have looked back at photos of your engine and you have the civilian type manifold made for a Zenith carb and the orientation of the carb flange mounting is different to WD  manifolds (inc. QL), also it is a different oil filter to the military ones, so mounting holes for that are different. It depends if you are changing the carb to the WD spec. Solex.

[Neilmwd]

Thanks for the info! I plan on fitting the correct inlet and exhaust manifold over time and if I ever find one. Also I’ll be changing the oil filter to a military spec. I have bought the correct scolex carb still in its wax paper but can’t be fitted unless I make some sort of adaptor. Anyone selling the correct bits I would be very interested 😁
