Differences between civvy and mod spec 90

Hi Guys,

Ive just picked up an ex military 90, its a 1988 model with a soft top and 2.5 nad, and I was just wondering what the differences are between a standard civvy spec land rover and the military spec one...

There are the obvious ones:

Soft top

small "roll bar" (how good this would be if you were to roll Im not convinced?!)

lack of black plastic panels around the headlights

screw on mushroom style lens

slash cut door tops

lack of things like clock/cig lighter ertc inside as well as having the 6 way military lighting switch.

I was wondering what if anything is different with the chassis / axles / bulkhead / engine etc etc mine seems to have an extra fuel filter on the chassis behind the fuel tank as well as the one on the bulkhead (dont remmeber seeing that on a civvy?)

part 2 of the question - with the parts that are different how easy are they to get spares for and where from

Its slow and noisey but I love it :-)

Cheers

Ben

You've listed most of the main differences.

also the 6 way lighting switch (with convoy lighting),

usually HD rear suspension.

sometimes 4 pin rear diff's and HD halfshafts (best way to tell is just pull a shaft out... if its 24 spline (and assuming the rear diff hasn't been changed for a later fine spline diff) then you'll have a HD diff.

split door with the angled glass

gearbox might have lowered 1st and 2nd gears (see if it's suffix 51A)

the second filter is in fact a sedimentor, a kind of pre-filter that catches larger lumps of poo and water, mainly from jerrycan filling.

some have suppressed heater motors and spark proof rear silencers. (for when being worked near fuel)

do a search on the web, there are several sources of the full military parts book to download, or fling me your email address and i'll email it over.

I've just said the same on another forum! It's the 1991 parts book that's needed.

Cheers guys..

All handy stuff.. :-)

The rear does seem pretty firm so guessing it has the hd suspension, I'll have to take a look at the half shafts at some stage as well :-)

I was thinking of dropping a 200tdi in at some stage, the problem I have at the mo is the low oil pressure light comes on at idle once warmed up a little, going to check the obvious things but if I cant fix it without a rebuild I may as well swap the engine for something with a bit more go :-) although not sure what the ratios will be like....

Cheers

Anyone know of any more of those military parts catologues?? I was really interested to see what spec my 90 was issued with, as I think it has been through a couple of different guises while it was in service.

The reg was 57KG88, the reg's on the sept 86 catalogue starts at 79KE, not sure of the relevance or if it means mines loads older. Interestingly, it was only brought into service in November 88 according to the cast off documents.

The KG bit means it was issued with a 'soft' 2-spoke steering wheel as in the 300 TDi defenders, (as opposed to the hideaous 4-spoke plastic thing on the others), (but unfortunately without the 300TDi as the MoD were too cheap at the time to buy any), it also should have disc brakes on the rear axle as opposed to drums. It will also have had the Mk6b version of the 19J engine fitted - which all earlier ones were up-graded to later as they failed - its only a different engine breather set-up so no big deal really. If it was a hard-top some of the pioneer kit stowage will be above the back door, other than that, same as all the other 90's about at the time.

Thats from my failing memory of the first batch of KG's arriving at my unit out in germany at the time.....

I answered this today at work but then things went mental so it may appear twice.......

Back in the good ole days, out in Germany, just after I wrote off the first 90 Defender to reach the Regt by shunting it into a tree on guard, we got the next batch of 90's - all with KG VRNs. They were special - they had a newer engine - the Mk6 B (all it was was a 19J with the engine breather system tweaked a bit) disc brakes on the rear axle as opposed to drums and they had some of the pioneer tool stowage moved to the roof rear panel above the door. But the best bit was the loverly squashy steering wheel like the civvy defenders got (only they got a 300TDi which we couldn't afford at the time as the Russians were coming) to replace the hideous 4-spoke thing the others had. Other than that nowt much was changed.

Any other differences would depend on the unit/theater it went into first off, but unless it was something really special, then a Rover was pretty much a rover in those days as all of the specials tended to be very role specific.

I scanned those two catalogues originally.

I scanned them at work and in doing so ruined their scanner. which they never replaced as the photocopier could double-up as a scanner, but the quality was dreadful so I never did any more.

I've also got the catalogue for the 1986/87 military 90's, as well as the catalogue for the 1990 military V8 110's, and as soon as I've setup my swish new HP ScanJet at home, I'll scan these and put them up on my webspace.

When our TA Regiment were issued with a large number of brand-new 90's and 110's in 1987, the REME LAD that I was a member of, got issued with the 90 and 110 civilian parts books + these Supplementary Military Parts Books. These became obsolete when the AESP (Army Equipment Support Publication) parts book was eventually issued, so I thoughtfully took them into protective custody :rolleyes:
