Hello leafers

Friend of mine has a 1974 Series 3, petrol, unleaded. That's about the limit of his knowledge on Land Rovers. He's had it about 5 years, not used often and not been serviced since he's owned it. He's asked me to help him change his tranny oil.

Can I assume its much like my Defender? Find the sump, drain it, covering the drive with oil, then refill, cutting self in several places and getting 2 litres of oil up your sleeve?

p.s. a tip on what oil and how much would save me much agonising seaching. Keep finding different opinion

From 1974, it's likely to have the old type of oil filter (You are going to change the filter, aren't you?) This offers another opportunity to see oil spewing everywhere. When changing this, remove the casing, complete with the old filter cartridge, and dump the cartridge. Then clean the casing out, and put the new filter cartridge in. Be sure to remove the old rubber ring from the base of the filter housing (I use the point of a very small screwdriver) and put the new ring in place. Then start to screw the filter casing on (big centre screw), making sure that the casing goes in square and sits on the ring. No need to overtighten as the rubber ring makes the seal.
The sump plug is on the corner of the sump, and just needs unscrewing. Don't lose the copper sealing ring (or fit a new one). After 5 years the oil is likely to be very dirty. To do the job properly, drain while the oil is warm (it runs more easily). You will need a lot of oil (6 1/2 litres or 11 1/2 pints) to refill.
It's well worth spreading a big sheet of cardboard under the vehicle before you start, as it's almost impossible to do this without some spills.

If it is the transmission oil then it is EP90 in mine S2a.
It is just as described, getting covered in the horrible smelling stuff!
If it has not been serviced since he got it I would be doing all the fluids!
The other way to do it is get him to do all the work getting dirty and smelly and call it 'teaching him'

Good luck

John.

Apparently you need EP90 GL4, and not the standard GL5, due to bronze bits in the gearbox. Much debate about whether it makes a difference but I got a 20L drum of Smith and Allan Ep90 GL4 for a decent price on eBay!

Axles take the same oil, so does the transfer box and overdrive if fitted

Main gearbox 1.5l transfer box 2.5l. Filler plugs are accessible from under the passenger floor. You'll want the squeezy bottles with the extending tube to get it in. Detailsn here :-

Great. Many thanks guys. Its the transfer box he's asked me to help him with, so thanks for the comments.

Yes I agree he really should do all the fluids whilst he's at it.

Like the idea of 'teaching' and letting him get covered in oil
