I have just bought a 753 with 1500 hours everything appears to work except there is a huge hydraulic leak from the chaincase. Apparently both drive motors are leaking. The seller is going to pay for the repair as I bought a "Bobcat ready to work". But I have a few questions worrying me. If the dealer reseals the drive motors what is the likelyhood of them leaking again quite soon? Because something has caused those seals to leak, either dirt or bearing or shaft wear. Would it be in the drive motors or the seals between the drive motor and the carrier? How concerned, about repeat leaking problems, should I be? A new drive motor is $999.76 and a reseal kit is $80.00 If the seller wasn''t paying for the repair I would be tempted to pull both motors and try to reseal them. Maybe I will have to do this in the future!?!?!? Thanks, Graham.
