MF50 Diesel Questions

Well-known Member
I need to do a little service work to my MF50
diesel and have a few questions.

1. I am almost 99% sure my tractor has the AD-152
Perkins in it (vs the AD3-152, which I think some
later year model 50's may have had). Can anyone
confirm my tractor has the AD-152 engine? Based
on S/N (532855), I believe mine is a 1962 make -
52 years old and hardly broken-in... ;-)

2. I asked the above because I need a valve cover
gasket for the engine. The guy that replaced my
head gasket didn't warm-up the engine and re-
torque the head, so I'm going to do it. The valve
cover gasket is a part numbers based on A3-152 vs
AD3-152. Anyone know if NAPA carries cross
referenced Perkins/MF gaskets?

3. Hydro oil. For years I've been using the
MF1103 90wt oil. I believe it's 100% mineral oil,
but last time out at the MF dealer, the price was
crazy high. Tractor Supply carries 100% mineral
oil in their Traveller® Ford Tractor All Mineral
90 Transmission Fluid, 2 gal. About $17 for a 2
gal jug. Any reason I shouldn't use that - is
100% mineral oil just that, regardless of brand?

Finally - I can't explain it, but even though I
bought a new JD tractor, I still like this MF50.
Such a nice machine all-round. I've had it for
over 10 years, take care of it, but run it hard.
Should I back-off now that I have a new tractor?
I still like using this one, it's handy, but I
need to make hay with it (cutting, raking and
square baling) and some heavy brush hogging chores
too. What do you think - pedal to the metal (with
care) and run it until something breaks (and of
course fix again) or lighten-up? Anyone still
using their MF50 diesel or 135 diesel with the
Perkins engine hard, all day long - just like it
was a new tractor? My MF50 sure takes a likin'
and keeps on tickin'

THANKS FOR YOUR HELP!!!!!!!!!!

If the fuel injectors are vertical, it is the older style indirect injection engine. The injectors go in at an angle on the later direct injection engines.
 
The tractor was made to work. I would not be afraid to use it for any job within its rated hp capability.

Working it is better than letting it set around IMOP
