Hey everyone, long time reader, first time poster.
I am working on a friends '01 discovery and am having trouble getting the timing cover off?? Does the oil pump have to be disassembled
and or the oil pan removed? The studs on the bottom of the cover are preventing me from tilting the timing cover out far enough to get it off the dowel pins.[/QUOTE]
They are not dowel pins. They are studs. When the switch happened to the GEMS timing cover, the three bolts that came up through the sump andf thread into the timing cover bottom were changed to three studs coming down from the timing cover bottom through the sump. You will see three nuts at the front of the sump that thread onto those studs.
What you are doing now, by tilting the cover, is either cracking the timing cover (800-900$) or the sump (400-600$) so I would back off for a little rest and a cup of tea or a beer depending on your country of origin.
Undo the nuts on the studs. However, I am not sure that will allow you to
remove the cover anyway (as you will still have to pull it up) and I am not sure it would help you if you could (depending on which model you have).
I think I can remember 3 different timing covers from GEMS on. One has the oil pick up pipe attached to the pump cover and that will have to be removed. That might require the removal of the sump (which is not difficult.).
Have you removed the crankshaft bolt yet? If not, how do you intend to do that?
