Hello all,

is there anyone who has a scrap transfer box and would be willing to send it to me if I pay the expenses? I would like to see if there is a way of getting a vacuum tube to the bottom of the case as a way of draining the oil then refill with the specified amount of lubricant?

Rob's post on the same subject mentions removing the drain plug but my downloaded Jaguar workshop manual gives a procedure of removing the output coupling and oil seal and draining the oil that way, is the latter due to an earlier specification box perhaps?

Hi Alec
I have just had the oil change done on mine using a different method from another forum.
It took them about an hour and half and didn't involve jacking the car up sideways.
It's in a PDF file with a lot of pictures so I don't think I will be able to post it on here but if you (or anyone else) wants to PM me I'll gladly send it off.
The car is a lot quieter now although the whine is still there it has moved much higher up the speed range.
You ought to be careful using a vacuum pump as pressure seals don't always take kindly to being subject to a vacuum.

Hello Steve,

thanks for the reply, I'll pm you my e-mail address as I would appreciate that write up.

Perhaps vacuum is a poor description, it is actually an air driven brake bleeding device so the pressure is quite low, it's basically a typical air powered fluid gun except that the normal suction tube is now a flexible tube which goes to the bleed nipple and the canister catches the fluid.

Alec, pdf sent.
Actually, from your description, it looks like a similar method. The only real difference is flushing it 3 times with a mixture of new oil and engine flush, running the car with the wheels jacked up and spinning.

Hi Everyone

As I run a good 'ol diesel X Type I don't have the worry of transfer boxes and as such am not overly familiar with the casing, location etc but as this is such a common problem.....

Is there a way of carefully 'engineering' a drain drain plug into the casing? I spoke to a chap earlier in the year who had drilled the turbocharger housing on his diesel in order to gain access to the turbo blades to clean them, and wondered if a similar thing could be done on the transfer box.

Just a thought?

Cheers, Steve

Hello Steve,

that was one of the reasons I wanted to have a close look at one, but going from the pictures it is probably a die cast item and is unlikely to have sufficient wall thickness to do that without welding a boss on.

I think the method you outlined earlier is a workable solution.
