Hello, I just bought a 1972 Ford LGT 145 Lawn Tractor. Overall its in good shape. My #1 problem is the Hydraulic 2" cylinder that lifts and lowers the mower deck is leaking badly when the deck is lifted and lowered. What do you all suggest.
If the cylinder is leaking from the seal around the rod, you will need to get the cylinder "repacked". The cylinder has to come apart and have all the internal seals replaced. You must make sure the rod is not pitted with rust, dinged up,etc. or it will destroy the new seals. If it is in poor shape, sometimes they can be repaired or re-chromed or simply replaced. I just recently did mine on my Bolens. Had to file/polish down some rust pitting and dings and some were filled with JB weld and sanded down with 1500 grit. Others were filled with braze and similarly polished down smooth. Silver brazing is also a good or perhaps better choice I would think but have not tried that option. In any event, if you elect to repair the dings pitts, and some of the chrome plating gets worn off, be sure to treat the exposed metal rod with phosphoric acid to "phosphotize" the steel which gives a small degree of corrosion protection. If the repair is in an area exposed with the rod extended, store it with the rod retracted so exposed/chrome worn area won't rust. My seal kit cost me about $42 bucks. Local hydraulics shop was able to match up the individual seals by sight since the actual kit is no longer available.
