Loader capacity disappointment

[aczlan]

Mr.Wallace please tell us how you are gonna increase his lift? Just curious.

Probably by:

1. Loading Rear tires
2. Adding Wheel Weights
3. Increasing the hyd relief valve pressure to the max recommended pressure

All you need to do is adjust the relief valve setting ie increase the system pressure. But I am sure that is bad idea since the loader cylinders will put out more force then the rest of the tractor can handle.

It is not necessarily a bad idea, it depends on what the relief valve is currently set to and what the system rated pressure is. If the system is rated for 3000PSI and it is currently running at 2200PSI you can safely bump it up by 800PSI.

Anyone ever do a Bobcat PSI bump up? I assume its a shim deal in the relief valve.

The system rating is for the pressure that the pump, valve, fittings, cylinders and lines can handle. The tractor axles, bearings and frame members are not designed around the force generated at the higher pressure. I'm sure it'll work for a while but you will shorten the life of the tractor.

I saw a great video of these guys that modified a kids power wheels jeep from 12v to 18 volt. It worked great and was really fast...until the little plastic gears gave out. Same concept...smaller scale.

Kubota (for example) has in the service manual a "recommended maximum relief valve pressure", however they often come with the pressure set lower than that from the factory, as long as you do not go over their recommended pressure, there shouldn't be any issues. There is a thread here where someone had a L2350 that came with the relief valve set to 1300 psi rather than the rated pressure of 2500 psi.

Note: I do not recommend setting the relief valve pressure unless you know what you are doing and you know what the system pressure rating is. otherwise things could get expensive in a hurry.

A better analogy might be a 12 volt powerwheels car that came with a 12 volt battery which was stepped down to 8 or 10 volts. It will still work but it wont do what it was designed to do.

I agree if the relief valve was set low at the factory or buy the dealer. You need to put gauge inline to see what your're really getting.

Of course, I would not recommend doing it any other way, way too dangerous.

Dealer secrets.

First thing first make sure the releif pressure is set to spec.

 

[tinman955]

Line pressure check is deff the first thing to get a baseline on for sure.

Secrets haha thats funny, nothing is a secret anymore with the internet!!!
