hydraulic pumps

I was just wondering if anyone could give me some info on fitting a hydraulic pump to a 90? how much they are, how to fit them etc. any help appreciated!

Not sure how much, but they bolt to the back of the transfer case.

whats it for?

4x4winches.com - WINCH-A-MILE

this chap may sell you a pump on its own?

thanks for the link, basically i was just curious. i saw an article about a bloke who had taken the tipper body off a transit and put it on his 110, but it also had six wheels which was great! i know you can get landy tippers anyway i just wanted to know if you can get a pump on its own for things like this.

You could shove a electric one in for that. Thats how most of these ones work, however you do get ones for the transfer case for winches and hydraulic PTO.
