DG/DJ Spigot bearing
Posted: 28 Feb 2018, 11:47
I am just about to get my 1989 2.1 DJ engine rebuilt and am a bit confused as to the spigot bearing set up.
Looking through the hole in the flywheel I can see three sizes of bore gradually getting smaller. The 21mm in dia. spigot bearing I have, will not go through the flywheel. Presumably the flywheel has to be removed to put in a new bearing?
Should there be a felt oil seal just behind the flywheel? The Bentley diagram shows a spacer, what is this? Is there something that holds the felt seal in or does it just get clamped between the spigot bearing and the flywheel?
Could the second level of bore, I can see, be the remains of a previous spigot bearing without the rollers? because the new spigot bearing will certainly not fit in here as it is smaller than the hole in the flywheel.
The third and final bore goes into the crankshaft quite a way, is this just for grease?
I don't really want to take off the flywheel to have a look, as the engine is going to the rebuilders soon and they will remove it anyway. Just curious as to how everything fits?
