743 Tow Valves?

[rick427]

Does a 743 have tow valves and if so, where? I may need to winch a 743 up on a trailer and don't want to damage anything in the hydraulic system. Thanks, Richard

Humm Pop the hose off the wheel motors, on that model if I'm noit wrong. Most people just drag it up on there trailer.

There are no tow valves in the 743. I have heard of people dragging/rolling the machines while someone moves the steering levers to allow the wheels to spin a little. If you are concerned about the hyds, set the parking brake and just drag it, wet the area with water to help it slide easier.

If I recall correctly there are some relief plugs that can be taken out of the pump somewhere to allow you to tow the machine. I've never done it this way but remember seeing it in a manual somewhere... There are a bunch of Manuals available on this forum that Oldmachinist has generously put up if you need one. Hope this helps...

The potential problem with towing the machine while the relief valves are removed is the possible damage to the drive motors from being rotated without lubrication.

The older machines could be moved by unbolting the hydraulic motors from the gearboxes. As mentioned above it is not a good idea to move the machine by allowing the hydraulic motors to spin, unless you fill them with oil and loop the hose. Most newer Bobcats can be towed by disengaging the traction lock solenoid but again, only for a short distance.

I personally just use brute force and drag them around. Even if you can wet the floor of the trailer to help it slide.
You can buy tow valves, but have you seen what you have to do to access the plugs to installed said valves? honestly, drag it around with the wheels lovked up or open the lines to the motors and move it SLOWLY. Un-mounting the motors from the gear boxes is a good idea too. 3 hoses and 4 bolts, it will roll easily then.

There is a special melroe tool that is used when towwing a 743etc. The towing tools are fitted in place of the relief valves in hydro pump to allow towing at low speed..
Has anyone ever actually used these or even seen them as I would like to make a set if a sketch/drawing was avaiable.

Thanks to all for your informative replies. I wound up not buying this 743, so didn't have to deal with getting it up on a trailer, but if I had, the knowledge about how to move a dead machine would have been very useful. - Richard
