hydraulic pump

[RWolf]

I had to replace most of the hydraulics on my 14HP Power King FEL and used the Haldex 7gpm pump off of a belt. They work very well and were very inexpensive compared to some of the others. Of course now that I got the pump working good I need to rebuild the cylinders. The nice thing I like is that if I wanted to I could use them as a hydraulic motor.

Another nice thing about belt drive is the cheap ability to change pulleys. Had a buddy who built a splitter and had plenty of speed but a little pressure would stall the engine. He was all set to buy another pump when I told him to put a smaller pulley on the engine. Even though it slowed the cylinder down a bit,it was still fast enough for him and definitely cheaper than another pump.

The Cad Digger plans of built and prov-en models have been around a while. Any defects for them probably has been worked out by now. If you try and go from scratch, you have a lot of work ahead of you. If you purchase prov-en plans, you save yourself time, headaches, and money, unless you already have the metal, but understand that the metal has to hold up to the force of the hydraulics, and if done wrong. you end up with a boom or something in the shape of a pretzel. Not really that bad, but you know what I mean.

I looked at the CADDIGGER plans. Do you have any approximate idea of about what parts would cost to build this for my craftsman?

Thanks

Most of the guys I have talked to have at least a couple grand tied up in towables...

I believe that some of the CAD planes have a 3 pt design. You should be able to obtain the large metal locally, and then acquire the valves, cylinders, hoses, etc. The cost would be variable depending on your scrounging abilities. Some people can just look at something and copy the item. Most of us have to have some kind of plan.
