    S1 2 litre Oil Pressure Adjuster - Confused, need help

    Gentlemen,
    I apologise in advance for so many questions. This is my first Land Rover S1 and I learning, but just fast enough.

    todays puzzle for me is in relation to the Oil pressure Adjuster. The work shop Mall and the Parts manual both agree about what is require, but what came out of my 2 litre Spreadbore is slightly different.
    The first image is the layout according to the Work Shop and Parts Manual.
    This clearly shows a round home ball, and a plunger that is designed to insert part-way into the spring.
    Oil-pressure-plunger.jpgOIl-pressurer-Ball.jpgcomplete-Unit.jpg

    The first different is my plunger is hollow and the spring appears to be designed to insert into that hollow. from there I am not sure how it works. If I am showing the plunger the wrong way around, then the ball would ride against the slightly angled end of the plunger, which would not seem right. However, if it is shown correctly in my image, then the ball would sie in the slight recess, which makes sense, but the spring would be riding against he angle surface, what seems to have been carefully machined, and not accidentally.

    I also received have 2 different Balls in the sealed container. So I am confused where the second one has come from.
    One is a plain chrome ball as illustrated in the Parts manual but the other is hard plastic with a white dot on the top and an extruded section and clip feature that looks like is was design to clip onto the spring. The fit is perfect. Ball-image-2.jpg

    I did not remove the adjuster from the engine, as this was done by my mechanic friend, and he put everything carefully into a sealed container along with the Oil Pump. . As a result, I am not sure if I have the wrong parts, updated parts or something perfectly OK, if I knew exactly the order in which they fit together.

    I am hoping someone can recognise these odd parts and give me some advice on how to deal with them


    regards and thanks.
    Jeff

    Hi BSF,
    I don't have a usable or reliable engine number. The block was changed by Land Rover in around 1957, apparently under some warranty. They took everything usable off my 1953 Siamese bore engine and put what could be use into the later Spreadbore block.
    The NSW Police then stamped the block with the number N602166 P, N being for NSW and P being for Police afixed (I have been told)
    As far as I know, this number has no relevance to anything at all. It was Land Rovers practise at the time, not to reapply block numbers for fear of creating major problems over time, so I have a number that does not help anyone, as it is a pure invention of the NSW Police at the time.
    A number of our members on this forum remember those practices back then and have confirmed that information to be correct.

    regards
    Jeff

    As far as I can tell there were only 2 arrangements used on S1 L/Rs.

    It is entirely possible that the net could be cast wider - were there different arrangements on some contemporary Rover cars?

    Good point - the illustrations in parts books often do not cover all alternatives!

    Sometimes the ball bearings were used when the bore of the relief valve was scored, and the relief valve was prone to sticking.
    We had this problem in Saudi when sand would get into the oil! This was in RV8s but same principle.

    Gentlemen, many the ask for the help.

    BSF hit the nail on the head with his second image. That is exactly what I have and that image tells me how to assemble it correctly.

    That just leaves the question about where this strange ball-like part came from and where it belongs. Any thoughts?

    Jeff, is it too obvious to ask your supplier? Perhaps the mystery part was mispacked at some point.
    Cheers Rob S
