Checking the gearbox oil level

NB the information on these pages refer to Rover 825 diesel cars only, this procedure should not be used if you have a petrol version of the 800. Refer to the appropriate manual for your car.

This is a manual 5 speed box. The version fitted to my car has this information on a plate affixed to the gearbox casting.

 

Cars made up until 96 had the T650 box, and after (ROVER 800 Diesel models manufactured from VIN 230967) the T750. What difference there is I'm not actually sure, the only thing is you add three quarters of a litre of oil to the T750.......

Remove the front left-hand wheel. Towards the front of the plastic wheel arch liner there is a panel Remove this (2 screws) and this will expose the end of the gearbox. Carefully clean up the area. You should now find a rubber plug. Pulling this out allows you to check / top-up the oil level. On the end of the gearbox is a label, which looks something like this:  

According to the Rover manual, this is how to proceed.

 

Carefully remove the electrical connector.

On my car a 15/16 inch AF socket fitted the reversing light switch. It needs to be a long body type or a box spanner to avoid damaging the electrical terminals. Don't lose the washer on the switch, you are supposed to fit a new one but I just re-use the old one with a smear of grease on the mating surface.

Pour the oil in here until it runs out of the level hole. Then pour the extra half litre of oil in through this hole (three quarters of a litre for post  96 from VIN 230967 with the T750 box ) ..... remember to replace the level plug first!

I have been told you should fit a new rubber plug although this is not stated in the manual.
