Does the triple row shaft approach incorporate DOF? Otherwise how are its bearings serviced?
The triple row uses splash lubrication, like all other LN retrofits other than the Solution.

Below is the IMS I sent to LN Engineering with a view of the beat up bearing race.
Below is the rebuilt IMS and a view of the new IMSB. This is how I received it back from LN Engineering (well the flange was actually attached to its stud but that hides the bearing for a pic.). If you could enlarge the photo you can actually see the ball bearings and see they are not sealed.
I bought an old style IMS with bearing on ebay - very hard to find - to rebuild my 3.2 with a failed IMS. After reading Pedros thoughts on IMS bearing failure I convinced myself to remove the bearing and check for oil in the IMS, and boy howdy did I find it! Ther was about half a cup of rancid engine oil in the IMS. It was so bad there were chunks of what appeared to be baked oil floating around in there. It even smelled bad. The bearing seals looked good, and the bearing feels ok. No evidence of corrosion on the bearing inner surface or interior of the IMS. Still, a replacement beaing is in order. I see two paths for oil intrusionand subsequent acidification into the IMS. 1) through the non metalic seals on the OEM bearing, 2) around the bearing to IMS interface. I wonder if falures are determined by which path the oil takes?
