Manual Gearbox - Oil Change

[JoeC]

Looking at changing the manual gearbox oil but not too sure where the fill and drain plugs are. I've looked on Lush Projects but none the wiser.
Thanks in advance.

The filler / level plug is closer to the top at the rear (passenger) N/S of the box ..

To check the SAE75W90 gearbox oil (Not Hypoid) .. park on level ground .. remove the filler plug .. the oil level should level with the filler hole ..

To replace the 2.5 litres of oil .. remove the two drain plugs / sealing washers below the filler plug ..

As is always good work shop practice .. .. make sure you can remove the filler / check level plug .. before .. removing the drain plugs ..

Drain the oil .. when replacing the drain plugs smear some gasket sealant onto the cleaned threads ..

Refill 2.5 litres of SAE75W90 gear oil or until the new oil is level with the top of the filler plug ..

If using a torque wench .. the filler plug is tightened to 25 - 39 N/M ...

The drain plug towards the front (bell housing) is 40-58 N/M ..

The rear drain plug (prop shaft) is only 21 - 31 N/M ..

Hi Joe, is your vehicle 2WD or 4WD...

[JoeC]

4WD.

So far I have changed the oil in both diffs.

.. remove the two drain plugs / sealing washers below the filler plug.

It's these I am having trouble locating.
Anybody got any pics?

It maybe that part no: 17-323 is a modification 'plug' with a debris magnet attached ..

theres a section on the oil change points for the manual box and the transfer box (separate oil supply but same oil for this) in the manual if someone could ask ian if they can reproduce it on here.
to be fair its not really that obvious so do take care, its been a few years since i did mine so cannot remember, no ive not checked them since. .

I think my ...

drain plug is 17-121
fill plug 17-495A

[mikeWalsall]

I have the manual .. that's where I got the information from .. (page 181) ..

[mikeWalsall]

I think 17-495A and 17 -323 are the same but alternative parts ..ie: one with a magnet one not .. and would be drain plugs ..

The filler plug seems to be 99502 -4000 and maybe an 'Allan key' type ..

Thanks to Jim I am now sorted.

Fill plug ... 99502-4000
Drain plug#1 ... 17-121C
Drian plug#2 ... 17-121

You can see all three in the 2nd picture ...
drain plug#2 is what I am pointing to
the two brown ones - top fill and bottom drain#1

Hope this helps but please correct me if I am wrong.

** PLEASE IGNORE THE 3RD PICTURE - IT IS NOT A FILL POINT **
