Earliest model Land Rover

[peterg1001]

This may not be the right forum, but here's the questions anyway:

What was the earliest model Land Rover which had an automatic geabox, cruise control, and was capable of pulling 2000kg?

Thanks, Peter

Someone will be able to answer this I hope. It will be a classic Rangerover some time in the eighties I expect, although cruise control may have been a little later.

cruise control and you may be looking at a disco, but I would have thought it would have first appeared on a range rover.

Nothing here in the 2 and 2A section thats for sure!

I would say early '90s - Discovery Series 1 or the later classic Rangies.


Speaking of auto and CC, apart from the North American Spec, I don't think these have EVER been fitted to a "shed class" (ie: Series, 110, Deefer) Landie!?

My previous S2 had a hand throttle and automatically jumped out of 2nd gear - Does that count?:D;)

Right from the start, a SI with an optional govenor attached would have had cruise control, and then standard with the introduction of the 2L diesel.

Maybe so, but no auto and certainly no 2t tow capacity! :p

My guess would be RRC from very late 80's or early 90's

Aaron.Not quite correct and not a complete answer as half the question was about an automatic gearbox.

Back to the governor topic.

There are two types of governors fitted to Series Land Rovers, the first type was fitted when a PTO was fitted. This adjusted the throttle setting to keep up constant revs during PTO work and differing loads offered to the PTO impliment. To use it as a very crude cruise control is possible but only to the extent of a single RPM irrespective of the gear, so the vehicle will run at say 2K RPM in top, at 2K RPM in 3rd, 2K RPM in 2nd and 2K RPM in 1st. A cruse control sets the engine revs to a constant speed of the wheels hence cruise.

The other type of governor fitted to diesels was actually a rev limiter, to prevent over revving of the engine. Not at all a cruise control.

As a person who drives a 2.25L diesel every day, the governor in the injector pump does indeed keep the engine revolution to what you desire, as described above when relating the the add on unit fitted to petrol engines. I frequently set my hand throttle to use as cruise control. It increases the power when a hill is reached (to maintain the same speed within reason, set by the available power available from the engine) and decreases the power when descending. By keeping the engine at the same number of revolutions per minute, and the gearbox in the same gear, this will act as a form of cruise control.

The CAV injector pump used on the Land Rover 2.25L diesel is a governing pump, as well as being a maximum RPM limiter.

Correct. At least this was the case for the 1961 2a I owned, and for the 1981 S3 I owned (pretty certain, but I hardly drove it - engine had been dusted). It is possible some had a different model pump, but I doubt it.

Remember, the 2.25L diesel can be likened to a fast revving tractor engine. The injector pump worked on the governor principle, while modern diesel car injector pumps try to work like an accelerator.
