Predominantly metric, but there are others. Keeps you on your toes, like a tall woman.

The 110 with Isuzu is a real mixture!

With that engine, probably dominantly metric, but there is quite a bit of Unified threads, mainly UNF, but I would not be at all surprised to know there are some Whitworth or even BSF, although I can't think of any off hand.

The original Landrovers in 1948 used all Whitworth, BSF and BA threads (plus a few specials). By the end of Series 1 production in 1958, the change to Unified threads had begun, but was still incomplete when Series 3 production ceased in 1984, by which time the change to metric threads was well under way. Since a lot of parts are interchangeable between models, you can expect surprises.

As has been alluded to - LR changed from imperial - metric during the 80's. But they did it ad-hoc - as each kind of bolt ran out!!! So you are likely to experience some of each.

What year is your county? My 1987 model has almost all metric (think I have found a couple of non-metric, but can't remember what).

At least the engine is ALL metric!!!

My 85 rangie has metric brake lines, that was one of the first things to change.

my Nov '98 130 still has some UNF bolts.
The output flange studs on the back of the t/case (parking brake drum) are UNF .....

In my 90/110 workshop manual, SLR621ENWM Edition 2, there are four pages, 07-3 to 07-6 devoted to identification of metric and Unified threads.

According to this all bolts and nuts are marked, metric with an M on the head, nuts with >>>, and Unified with a recessed head on bolts and 000 on the nuts. They also note that threaded rods, if unified have a short core diameter section at the end. There is a warning that brake piping is metric, but power steering piping is Unified thread.

primary engine components will be metric, drive line and gearbox will be a mixed bag brake fittings should be imprial about pre 85 metric after and body fittings will be random....


and thats assuming that a previous owner hasnt had his way with it.

Thank you all for your input. I am going to pick one up and have a fair drive to get it home. I wasn't sure what I might need to take in the way of tooling but knowing it will most probably be a blend is a start. Except if it is Whitworth or that other old stuff, that's why I have seven sizes of multigrips and a set of shifters in a quick draw tool belt!
Thanks again.
I'm not really so gash that I have seven sets of multigrips.
