thanks Fenby 1976
i should have added to the original post, it is a series 2 chassis, with a series 3 safari body, and converted to diesel, the servo does not have anywhere to get the vacuum from (so i think it has never worked) so this is why i asked the question. but thanks again fenby for your sensible reply.

Ahh... I see. What you need is one of these then:

Part Details

I can see why you're considering doing away with the servo now! I doubt they sell too many of those at £370. Try ebay for a secondhand one. I don't know if it would fail the MOT if you just swapped to a non servo system. I would imagine that if the MOT system has recorded that it's failed on the brake servo then the tester would be reluctant to pass it with the servo removed. I've got a 1987 Ford Transit engine in mine which has a vacuum pump on the back of the alternator. It might be worth your while having a look at one of those and seeing if you can graft it onto your engine if you can't find one of those throttle bodies. I don't know what the later 2.5 diesels and Tdis use to create a vacuum - that might be worth some investigation.

Hi
mine is an early series 2a/3 1971, and i asked the question cause i was looking at the haynes manual and they stated that not all early series 3 where fitted with a servo, so didn't know if mine was meant to have one.

I've got a 1971 Series III 109 2 1/4 diesel which was originally a pick up and that does not have a servo - the brakes are ****, but it does have an ambulance body on it now which can't help. My series III parts catalogue does not list that throttle body I was talking about. I got the part number from My series optional equipment parts catalogue. I'd try to get the servo working if I were you, but I suppose you could tell the MOT station that the servo is not correct for your vehicle and ask if they'll pass it without.

My Transit book says 55, 70 or 90 amps Bosh or Lucas. Land-Rover book says Lucas 34 or 45 amps.

Mines '77 and doesn't have a Servo. It's a SWB, I don't think the servo became standard until about 1980.
I think all SerIII LWB had a servo though.

My 1971 SIII 109 diesel does not have a servo, and the throttle body fitted to the inlet manifold on the 2 1/4 diesel to create a vacuum for the servo is not listed in my SIII parts catalogue, only in the optional parts catalogue. So it looks to me like the sevo was not standard on all SIII 109s in particular the diesels.

servo was an option on early 109's,mine isn't on the road yet but i'm sure it'll frighten the crap out of me seeing as i don't have one and it now has a v8 in it.

I've just checked the SIII parts catalogue and there are 2 types of non servo brake master cylinders listed: 90569126 (88" up to June 1980); 90569128 (88" from July 1980 and all 109") so servos must have been non standard on some 109s.
