I'm in the process of repairing a pesky and substantial leak from the rear of the Front Differential (L235DT) and have come across a part shown in the diagram that I can't locate. I've determined that the reason for the leaking stemmed from a missing Oil seal (#14 on the Front Axle Support) that showed no signs of ever being there, and also it was missing an O Ring (#10) that goes inside of the Oil Seal Collar (#6). No real challenge there, easy fix. Of course, to do this, the front axle has to be removed. Checking to see if I might need anything in the Axle Bracket after dropping the Axle, I find the Thrust Washer (#14), Bushing (#19), and the O Rings (#'s 9 and 8) only. No signs of the Seal Cover (#2). Looking up the cost of this part, it is $93.67. From the diagram, I can not figure out where this Seal Cover is supposed to go and if is may be something that the previous owner neglected to replace because of the price (as a side note, I've noticed other areas on the tractor that certain short-cuts were done). Looking at it again and again, I can not establish if this is really a necessary part. If possible, I don't really want to spend another $93.67 unless absolutely necessary.
Is there anyone that is familiar with this particular part. Is it merely a rubber boot covering the end of the Pinion Bearing Case at the point where the drive shaft connects (I'm hoping not at $94.00). This has me and friends baffled by what the diagram is showing
Thank to all that might have some enlightening information.
