Introduction
Removal of lock rings
01
In order to remove and refit lock rings or split rings,
always use the correct pliers - Fig. 34.
Attention needed: the engagement holes (1) for pliers
are usually tapered in order to secure the pliers more
easily when removing or fitting rings.
But for that to occur, the rings should be fit so as the
small diameter of the tapered holes be towards the
pliers.
It will be hard to handle a ring when it is up side
down, since the tips of the pliers tend to be forced
out of the ring. See picture.
Besides making the operation more difficult, with
potential damage to the ring, there is serious risk of
the ring being abruptly thrown out, causing serious
injuries.
Always wear goggles.
Massey Ferguson special tools
These should be stored in their boards, properly
identified and numbered.
NOTE:
Otherwise, precision measurements like
crankshaft wear will be unreliable, and
can lead to serious mistakes!
Troubleshooting
This usually takes some experience. Even so, you
should follow a logical procedure, which will prove
its value on many occasions.
This basically consists of following a defined order
of problem solving with a "beginning, middle and
end".
Basically, we can define the steps as follows:
a) Determine what the problem is, by analyzing the
symptoms.
b) List the possible causes.
c) Keep a record of what you have checked.
d) Do the tests in a logical order to find the true
cause of the problem.

It is very important to talk with the operator
of the tractor to get the most detailed
description you can of the symptoms.
e) Work out the time and the parts needed for the
job.
f) Do the required repairs.
g) After repairs and before delivery, perform a final
check and if required a practical test by
simulating operating conditions.
h) If necessary, instruct the operator so as the
problem presented be avoided in the future.
