Bobcat 743

I recently bought a Bobcat 743. Having no service info on the machine I decided to change the seals in the rams, all fluids, and filters. I pumped out the chain box today and got about a 1/4 gallon of H2O from the bottom of the box. Any way with the drive chain box empty I discovered that the left chain was a lot looser than the right. I am wondering if there is a chain tension adjustment or what. Both chains seem to be in good shape, but this anomly has me puzzled. Any help or suggestions would shur be appreciated. I hate reinventing the wheel if sombody allready knows the answer. Viking1285R I have the service manual

Tilt it forward and mop it out with rags there is no chain ajustment but are some better new style guids one ten ft box of 80 HD will do one side with a few links left over

Were the lift and tilt cylinders hard to rebuild? I need to replace seals in all of ours.

If you are doing a complete service, use your old hyd. oil in the chain case, it will save you several dollars and will work just as good
