Bobcat 450 Plumbing help???

[diggerdave65]

Hi All Im in need of some expert plumbing help on my Bobcat 450 skidloader. (sorry I don稚 have the machines numbers with me now but will get them if if will help.)

If I recall correctly I bought it in 1994 -95. It was the smallest machine width-wise at the time at only 36 inches wide) It has the BICS system. I needed a powerful small machine that I could use to pop out Christmas tree stumps and not hit the trees behind or next to it. (trees are 6X6 grid). It works perfectly for me.

So my question is about Aux hydraulics. Lets say I wanted to add another cyl for a brush thumb. The question is how can I plumb this additional cylinder?? In looking at the machine it has all the factory bracketry on the lift arms where additional wet lines would be threaded thru. This leads me to believe it is possible. What do I look for on the pumps????

So if this possible given the 450痴 pump configuration, how would you operate it?? As it stands now the right and left foot pedals control the lift arms and bucket and the hand levers control forward and reverse.. how would I control the thumb???



Thanks in advance
dave

There is a kit for this. The control valve already has the extra spool for front auxiliay, the front aux is operated by moving the right hand steering lever side to side. There is a lock pin in the linkage that you take out to enable moving the lever. The kit includes all the plumbing needed to get fluid from the control valve out to front and back to valve.

Hi Thank you so much - that is exactly what I was looking for. Now any chance someone can point me to a dealer or site (hope this is not against rules..) that has someone knowlegeable about this kit? I tried 2 dealers near me here and got absolutley no where. I did google it and got no luck. Maybe it is no longer being made??
Appreciate any leads or info. thanks dave

I did the same conversion with my 440B last summer. Bobcat no longer sells the parts in kit form, only as individual parts. So you will need your parts guy at your dealer to look up the individual parts and order them. I have the tech bulletins that walk you through the modification and they do have the parts list in the back. Let me know your e-mail address and I will send them to you.

Cheers,
