    No Yellow Knob?!

    Just looked at a series 3 109 from 1974.

    It just had the red knob - no yellow one.

    Not seen that before.

    Does that mean when the sticks forward its 2wd and when the sticks back its 4wd? Or is it permanent 4 wheel drive and the stick just changes the gear ratios and not the 4wd ?

    Any thoughts gratefully appreciated.

    cheers,

    D

    The only Series Landrovers without a yellow knob were a few two wheel drive ones, very early Series 1 with full time four wheel drive, and Stage 1 V8 or Isuzu with full time four wheel drive (and these last did not have a red knob either, it was black and on the front of the seat box).

    My guess is that either the yellow knob is just missing, or it has some sort of a non-standard setup. This could have been a modification for single lever operation, or the fitting of full time four wheel drive.

    I would guess the truck has a different gear box setup and the red knobbed stick is for changing ratios and diff lock (much as the smaller stick in coil spring Land Rovers). Or it is simply missing...

    I thought it might just have been missing but could see no hole for it.

    I took it up a pretty steep slope but it went up ok red knob forward and then red knob back!

    It seemed slightly noisier with the stick back - but I wouldn't swear on it.

    All very interesting. I've never seen a Landy the same set up twice.

    Thanks for your thoughts.

    Did it have a Land Rover engine? I saw one once that had a T@#%&a engine and gearbox and another that had a Chevy engine and a T@#%&a gearbox.

    Have you looked underneath. Have a good look at the transfer case, & gearbox, where it all connects. might make it clearer. Bob

    good point but yep - original Rover 4 cylinder petrol. Took a quick look underneath - couldn't see anything unusual - but I'm no expert.

    I could understand if they just took it off - or it fell off! and they couldn't be bothered to put it back on , but couldn't get my head around no sign of the bracket or hole it would have gone through.

    I'm used to seeing bodges on Landy's but that looked unusually neat!

    All part of the learning curve. Drove fine.

    cheers,

    One of the members of the LROCV Series 1 group had a SIII with a prototype single lever transfer box. The vehicle was the RAF blue and had inner guards similar to the 110. Externally the box was the same as the regular series box.

    IIRC the lever moved fore and aft to engage Hi or Low and sideways to engage 4WD.

    Yes, I was wondering if it was a home conversion to do this. It would not be too hard to devise a mechanism where sideways movement of the lever did the same as the yellow knob. I think from memory someone here (Gromit?) has a Series 1 with a modification that has a second lever rather than the yellow knob, but this was done to enable deselecting 4H without going into low range. It would be hard to do that with sideways movement because of the leverage needed to compress the disengagement spring.
