[AT] 8.9 liter Perkins was collection dynamics.

[Cecil Bearden]

The high pressure 3000+psi for lift, the 1500+ for steering and then the 
+/-500psi for multi power clutches controls and PTO controls.   We had 
one for several years.  MF left out a snap ring in the PTO clutch and it 
did not work for the original owner.  It was 6 years old when we bought 
it.  We had to pull the cab and the top deck to find the problem.  A few 
years later my Dad put the wrong oil in the hydraulics and the multi 
power and PTO started to have problems.   Later found the o-rings were 
going bad and to repair meant nearly a complete disassembly of the 
tractor.   It went to Mexico.

A few years later we bought a 7030 Allis Chalmers to replace that 
tractor.  The Allis has the same features and a few more, but only one 
pressure system.   After I sealed off the dash to get the Air 
conditioner working it was  very good tractor and very simple. The 
problem with it now is a large diameter o-ring in the main clutch is 
going bad.  It means a split of the tractor, but can be repaired for a 2 
day job...

I really liked that 1155 Massey, but it developed so many problems and 
used so much fuel it was a pain.  The V-8 has to be kept running above 
1900 rpm or it gets hot...    Our 1155 was built while Massey was having 
a lot of problems.  I grew up in a MF dealership, and I bled red & grey, 
had red & grey underwear too.  But that 1155 we had just ruined Massey 
as far as I am concerned.   They got more complicated than necessary.

Those Masseys have a hydraulic system that has three separate pressure systems.   the O-rings can go bad and give you a real headache.   Make sure the multi power works and try the PTO on the mower to be sure the pto clutch is holding.    That V-8 diesel has to operate at a lot higher rpm than a 6 cyl and it uses a LOT of fuel....  We owned one for several years.
