How to Bore a toy steering box

flip · Jan 30, 2010

I heard that it is possible to bore out a toyota steering box. I realy dont want to run hydro so this would be helpful. So if someone can tell me how it is done, or where could I find out how to.
Thanks.

Im thinking your talking about drilling/tapping for hydro assist? If so search Pirate, Good pics of the area's do work on.

That has nothing to do with your steering box. That is modding your pump.

ya think a good external cooler would help at all Bill?? Or were you running one and still burn em up?

if you drill that resrictor out it will work a little better but the pump will go out right at the worst time & place, Ive seen it twice its a pain in the ass when you have to do it in the mud when its dark Trust me

5+ years on the same junkyard pump 3 of that with full hydro. Drilled restrictor completely out and shimmed the relief valve. Not a problem at all. Guess it helps that I run a cooler and a ginormous reservoir.

A stock Toy res. is not doesn't have a enough capacity to handle a moded pump. I ran a shimed and drilled pump with only a bigger cooler and it work but it wasn't very happy. I think the only thing that saved it was the bigger cooler.

I'm running 2 years on a drilled and shimmed junk yard pump. With hydro assist. I keep a spare in the trailer spare parts box but have not had any problems yet. A big cooler and a big resivior will keep these pumps alive. Sure makes a **** ton of noise though.

My system holds almost 3 quarts.
