Low flow to high flow conversion

[scottb]

Hi, I'm new here and had a question. I've had an 03 T-190 for a couple of years and would like to convert it to high flow hydraulics if possible. Does anyone know if this is possible and the components I would need to switch over. Thanks, Scott

I have never or know of anyone that has done it , I am pretty sure it would be possible but expensive and a lot of work , a trade in might be a better move --------------------I know for the Takeuchi's there is an aftermarket set available to convert them to high flow and none of the Takeuchi's have highflow to start with , the company is out of Florida , maybe talk with them as they might have some aftermarket thoughts

The only way its worth it is if your control block is the high flow version. I don't know if they are all standard flow or they cover both. If you need to change it to handle the extra oil, its not worth it.

Thanks for the information. I guess I'll ask one of the mechanics the next time I'm by the dealership with it.

I priced it out for my s185 and we were at $2100 for parts only. it uses a tripple gear pump (no idea why a double is not sufficent) that only Bobcat could supply at that time for @$1100
If the pump could be sourced elsewhere and you did your own labour its possible, but still expensive. plus the dealer would still have to program your computer to tell it the hi flow option is now installed.
Forget about hiring it done, better off to just trade machines.
If a aftermarket kit was available, that would be the way to go. if you find something, let me know, I'd like one too.
I converted my NH ls160 (simular size to a s150) and there is too not much to the setup on them. Still took a couple days of screwing around. A aftermarket company could easily supply that setup if they desired.
With bobcat the 3/4" lines are already on the boom and the couplers are the same, where as the NH had to be updated from 1/2" stuff. After that it should just be plumbing the supply to the extra pump and the pressure to a selector valve that combined the high flow pump section to the standard flow pump when high flow was desired and bypassed the high flow pump to the tank when it was not needed.
NH just plumbed the high flow section into the same control valve in a port between the 2nd and third spool, this way only the 3rd (aux couplers) spool seen the extra oil and the tilt and lift only seen oil from the main pump. (operated the same regardless of hi flow being activated or not.)
Only when you are not currently useing the lift or tilt valve, is the combined flow of both pumps available to the aux couplers.
The nice part is when your are using the lift and tilt, the front aux couplers still have a dedicated pump suppling them, but at a reduced flow (only the high flow section) as opposed to the attachment being completely starved of flow.

Thank you Ken. I will still look into it but you seem to have told me what needs to be done. Thanks, Scott

Scott, If you do it on your Bobcat keep me in the loop. I'd still like to switch my s185. If I don't end up with a hi flow track loader first.

TheTool (Shane) did a T300. He discussed it in the thread High Flow Conversion.
