| If you've got a very late model 748, you'll discover, as I did recently, that for some obscure reason they've changed the design of the "sludge trap" tube thingey, so instead of a simple hex head, there's now a cover plate, which needs a massive allen key (14mm from memory), and then the filter behind it needs the 14mm allen hex again to remove it. Best is to get a 1/2" socket set attachment for the allen hex. You can get them in Halfords as "car sump plug sockets".
It's pretty self-evident which type you've got. |
