Here’s a tool I’ve put together to aid changing the oil in your Land Rover.
The pictures show how I’ve done it and you don’t need full instructions cause you’ll come up with your own variations. The reason for this tool is because you need your oil to flow up hill into the filler hole on the Gearbox, Transfer box and Differential. Clearly gravity is not going to assist you so this project uses air pressure delivered from an normal car tyre inflator to push the oil up hill to where it needs to be.
Somewhere I have some left over Velcro cable tidies. I intend to find one and use it to attach the coil of pipe to the can handle.
Essentially its a 1 gallon water container which is filled with oil, the correct grade being 90w. I’ve used a one gallon container because that’s how I’ve been buying it. The tyre valve I scrounged from our local tyre garage. I asked one of the mechanics in the bay rather than going into the sales counter where I would no doubt have been charge £1.75 plus VAT. I got it for free from the mechanic.
I had some 5mm clear tube to hand so this was assembled into the can cap. I’ve used some SilkaFlex adhesive to seal an air tight seal round the tube and the tyre valve. This is also used to stop the tyre valve from falling out the hole. Note I’ve only used the neck of the tyre valve as my hole size since the base of valve would have used all the available space in the cap. The bulbous end has also been trimmed down using a hacksaw to make space for the 5mm pipe.
I’m not entirely sure the SikaFlex is going to hold out long term as the cap is made out of Polypropylene and I’m not convinced its firmly stuck. Time will tell and it may just need careful handling.
All you need to down is add oil to the can and attach your electrically operated tyre inflator and your oil will now flow up hill. Left over oil is now nicely stored for next time.
