Finally got the gear box sump off yesterday to do the filter and oil. Not too bad a job even with the car on the floor, however you do ideally want to be indoors as the gearbox internals are exposed to the elements; a windy day outside would end up with bits of grit getting in there!
I genuinely half expected to find metal in the sump, having read so many posts of failed HP24 gearboxes. However first good sign when the sump was off was that the filter was dated 2013, so it's been serviced before. I do have full service history for the car which mentions gearbox oil, but that could have been the transfer box so I wasn't sure if it had ever been done.
Everything looked ok in there.
Second good point was the sump contents was good, no metallic pieces on the magnets. They do accumulate a kind of paste of super fine metal particles which I would expect is normal, and is wiped off before it all goes back.
Now the first area of question was did I have the correct filter. The reason I was unsure was because there is a small O-ring that goes on the small neck that pushes up to the gearbox, however when offering the new filter up it seemed too small. An O-ring should give a snug fit into the recess it goes into but this didn't, in fact it appeared to be a couple of mm smaller diameter to the recess it went into. The new filter was exactly the same as the old filter though, but didn't seem right somehow and I wonder if there is a different seal that is needed for this gear box variant...
I didn't notice at the time as it was covered in oil but the old filter was actually cracked, quite badly, so it's possible this could have been causing a problem with oil pickup!
Got the sump back on and proceed to fill up. It took 5 litres cold. Then went into the filling procedure and it took another litre or so before hitting level. I had done this before so it was quicker and easier but still ended up with oil everywhere.
So now I have pretty much all new fluid in there, having done the flush just a few weeks ago, with a new filter, however a question about if it's fitted woth the right seal, or even if it's the right filter...
The old O-ring was fitted as in the picture at point A, which is where I put it on the new filter. However I am now thinking that maybe it should be fitted at point B, which is a bigger diameter and would stretch the O-ring a bit, it may be where it's supposed to seal to the box... I couldn't find any literature on this. Can anyone who has done this confirm what type of seal and where it should go on the filter? The O-ring had a very small OD approx 2mm.
I have a feeling I may be doing this job again at some point in the near future.
