4-7. REMOVE RIGHT END COVER ASSEMBLY
(SHEET 1 OF 7)
OVERVIEW
It is necessary to remove the right end cover assembly to perform the following maintenance:
• Remove components from under the right end cover assembly.
• Remove components from within the right end cover assembly.
• Remove the bevel gear assembly.
The sump communication tube, lube tube, oil
transfer tube and scavenge tube must be removed before the bevel gear assembly can
be pulled from the transmission Access to these tubes is gained by removing the right
end cover assembly. (The left end cover must also be removed to allow removal of
other tubes that go into the bevel gear assembly.)
• Remove the range pack (located under the left end cover) including the range input
shaft. When the shaft and bushing assembly are pulled out the left side of the
transmission with the range input shaft, the range output gear spacer and the governor
drive gear will lay loose in the right end of the transmission. Upon assembly, it will be
impossible to get this spacer and gear back on the shaft without removing the right
end cover.
