Rear Seal For Counter-Rotating Engine
This was posted on the GB Board on 2-11-04:
The owners of JD 6-404ís may want to put a note in the parts book regarding the rear main seal for the counter-rotating engine.
The parts book calls for AR 49650 which changes up to a new number, RE 17352, which is a directional seal, made for a standard rotation engine. I talked to Chicago Rawhide who made the original OEM seal, and for the counter-rotating engine, they said to use a C/R # 49920, which is a standard lip seal the same as the original.
