[AJD] Mike's B - crankcase

[Duane Larson]

Mike,
That would likely be the oil pump mechanism, and the oil filter.  The pump
has lines attached to it, so it is not that easy to remove just to get a
larger hole.  You have to remove them from above.  The normal access point
is by removing the plate on top of the crankcase that the crankcase breather
is a part of - that is large, and by rotating the flywheel (CAREFULLY IF
YOUR ARM/HAND IS IN THERE) to gain access to different parts of the bottom
of the crankcase.

It is easy for us to assume knowledge that you may not have - you are on a
steep learning curve working with your first tractor, so please don't be
afraid to ask any and all questions.  The next JD will be much easier (and
I'll bet there will be a next one :).
Duane
