MG MG Y Type - Disposable oil filter kit fitting

A while ago (well about 18 months...) I bought a modern adaptor to replace the oil filter canister on my YB with a spin on oil filter arrangement . The kit is well known and comprises an aluminium plate and a double threaded hollow metal 'tube' -one side screws onto the oil filter and the other presumably screws into the oil pump body. The trouble is what is the correct way of fitting it as it came without any instructions. Do I removed the existing (threaded?)tube in the oil pump - if so how as it seems reluctant to move. What happens to the sealing ring that the original canister screwed up to etc?

Thank you for sending me photos of what you are dealing with.

Your first job will be to remove the old pipe (A). This may be a push "interference" type fit as it is on the older style "hanging filter" oil pumps, but given the fact that Edney's have supplied you with a threaded pipe (D) I am hoping it will be threaded!! If not then you will have to seek getting the main housing threaded to suit.

Still, moving on and assuming it is threaded, clamp the pump firmly in a soft jawed vice and slide a "tommy bar" through the hole in (A) and crank this pipe out. This may well be in there tight so you may need some leverage on the bar. Even if it is an interference fit, turning it will help break the seal.

Once out moisten the seal (B) with motor oil, and place into the body of the pump/filter house.

Plate (C) will only then fit in one way so that the lip presses against the seal, and pipe (D) can then be screwed into place and wrenched tight. Personally I would suggest putting some permatite thread seal on it. Check to see if the filter will take the longer threaded end of pipe (D), and if so, use the shorter end into the pump/filter. Critical to this of course is that the receiever in the pump is threaded and to the same pitch as the pipe you are about to fit!! If the longer threaded pipe does not go all the way down the filter, then maybe the longer part goes into the pump - I don't know, but an educated guess would tell me the shorter goes into the pump.

When Plate (C) is secured in place with seal (B) behind it using pipe (D), moisten the seal on the filter with a smear of motor oil and spin on to threaded pipe (D).

Hope this helps.

Thanks Paul - I'll take a closer look. I am suprised that more people have not done this but if you have to thread the housing in the oil pump...no wonder. Let you know what I end up doing.

Pretty sure it would be a threaded pipe David, but as I have a YA and 2 YTs I cannot pass comment on the horizontal oil pump type. You may have to excert some force on the pipe to unlock it ... or it may come nice and easy, but do use a soft jawed vice to hold the body.

If you are really sure you dont wnat to retro fit the old style, at the risk of crushing the old pipe, you could just clamp the pipe in the vice and then turn the body of the pump. That may be easier than clamping the uneven surfaces of the pump.

Hope the above are useful to you.
