Mast wont come down
  • bob_c

I have an old Manitou rough terrain forklift recently aquired. On raising the mast high oil started to run out of the top ram between the outer and inner shafts quite fast, on raising and lowering a few times the flow reduces to a very small trickle, as the forklift hasnt been used for a while could this be a dry seal or worse ?
The other problem is the mast wont come down now more than about half way, it will rise above that point no problem but when lowering stops at exactly the same spot with the lower ram showing fully and the forks at about half height.
I have looked around the chains, slides, rollers etc and cant see anything stuck in the gear or that would stop the mast traveling down.
Any advice would be appreciated.
All other functions like side shift and tilt work as they should.

is this a compound lift cylinder? it sounds like it.
try lifting with a load and see if you come down then.
everything you are saying is pointing to an issue inside the lift cylinder which is unfortunate if it is a compound... $$$

I dont know what a compound lift cylinder is, how would I tell which type it is ? Where would the lift cylinder be is it part of the mast aseemlbly ?
I cant put a load on it as the forks are stuck up in the air.

A result!
I hand loaded a pallet of concrete blocks on to the forks while it was up in the air and on the third try it came down so maybe its just lack of use ?
I have taken it up and down with the full pallet on and it seems to work ok now although not tried it without the load, might be best to only elevate it when there is a load on in future.
Thanks for the suggestion
