Hi,
As it looks like I'm going to have to take my engine out to resolve a low oil pressure problem I'm thinking I will also fit one of the lip seal, rear main retaining plates at the same time.
It seems sensible to fit a speedi-sleeve to the flywheel boss at the same time but I've found conflicting information on the correct part number.
There seem to be three options people claim to have used, the SKF Part Numbers being 99186, 99187 or 99188. The dimensions of these from the SKF website are:
99186
Removable flange outside diameter2.188 in
Seal seat width0.889 in
Shaft diameter1.868 in
Shaft diameter, maximum1.872 in
Shaft diameter, minimum1.866 in
99187
Removable flange outside diameter2.203 in
Seal seat width0.563 in
Shaft diameter1.875 in
Shaft diameter, maximum1.878 in
Shaft diameter, minimum1.872 in
99188
Removable flange outside diameter2.203 in
Seal seat width0.295 in
Shaft diameter1.875 in
Shaft diameter, maximum1.878 in
Shaft diameter, minimum1.872 in
I suspect the correct version is 99187 as the 99188 has a very short seal seat width.
Before I order one does anyone have a definitive answer as to which is correct.
I don't really want to wait until I have the flywheel off before ordering unless there's no alternative,
John.
