QUESTION:I have an older yale forklift model #& year unknown. no literature It has a
chrysler slant 6 with hyrdostatic drive. The power steering & lift hydraulics
seem to be using the same resevoir. The transmission oilpan has 2 drainholes
about 3 inches apart. Whats that all about? Theres a dipstick close to the end
of the steering column entering the differential casting. Another dipstick is
in the breather cap of the lift oil resevoir . I need to know what kind of oil
goes where & the proper procedure to go about changing it
ANSWER: Best thing to do is to get a real manual. Tough to do if you can't
come up with the Model # and the Serial #. Are you sure there's no
stamped steel plate on the dashboard, or on the back of the starter
battery rack? If you absolutely can't come up with the Model and
Serial #s, you may want to try taking a set of photographs and showing
them to the yale dealer. Heavy equipment dealers are usually helpful
people.
If, on the other hand, you want to wing it:
- Never seen two drain holes 3" apart like you describe. Don't know
why the designer did that; sorry, can't help you here.
- Differentials always have oil; 90 weight gear oil is a good guess.
Certainly nothing with foaming detergents. Drain the old, and fill it
up to the dipstick mark with the new.
- I've always used cheeze tractor hydraulic oil in fork lifts for
the lift oil. Again, just drain out the old if it's ancient, and pour
in the new up to the mark on the dipstick. It's about $25 for a five
gallon pail in most auto part stores. I've been told that the stuff
is actually just straight mineral oil, but I do not know if that is
true.
