My 10mm plug stripped out so I wust welded a nut to it. It came right out after that. (the heat helped)

so, I just took apart my steering box and I'm all ready to drill and tap it. my problem is that I stupidly unbolted the input shaft housing before turning it all the way to the right until it stops to remove it, I got that and the piston out of there, but the piston was about 3/4 of the way or more from being off the input shaft, then it came off the rest of the way, there are a bunch of loose ball bearings in it and I'm not sure what to do to re-assemble it. it I just let the ball bearings chill in the bottom and try to put it back together, it's not too smooth, perhaps the bearings go inbetween the shaft and piston? hoping I'll get a helpful response on this by the time I finish tapping the box, and hopefully I explained that well.

thanks

Well for anyone rebuilding their box heres a "How too" http://web.archive.org/web/20050322011020/http://128.83.80.200/taco/box.html

I got my box back together and believe it or not it works! For the square cut teflon o rings just use a hose clamp to make them smaller once you get them on. Theres a pretty easy way to get the 44 little balls back in place.

On the piston the worm gear threads into, it has a cap that can be unthreaded and taken off. Then fill the little "tube with as many as you can and put the worm gear in an inch or so. Dump the bearing into the top of the piston and thread it in and they will fall into place. Took me about 5 minutes to get them all back in.

thanks man, I tried the tube thing, but didn't manage to make it work. what I did was grease the inside of the piston, and put 3 ball bearings in at a time, then ran them to the front as far as they would go (into the tube for the first few) and repeated. wasn't that bad, I kind of got a description of how to do it from that link you posted a little after I posted the question.

sorry for not seeing what you quoted earlier.

hopefully this will at least help someone else later on.

my restrictor plate doesnt look like that or come apart it is off of a 97 3rz anyone have any ideas.... i am thinking to just drill it out

freds40 · « **Reply #306 on:** Jan 11, 2010, 08:18:30 PM »

If your Taco pump is like the one I worked on with 2 smaller holes next to each other rather than 1 in the middle, then you can't drill it out. The restrictor on the one I worked on had a large air gap in the middle so drilling into it just opened up the whole area. Kinda sucked..........but now I know.

potter85 · « **Reply #307 on:** Jan 11, 2010, 09:37:37 PM »

mine has a single hole in it but it is one piece. so ima just drill it out and run it seems to be what everone else did.

potter85 · « **Reply #308 on:** Jan 21, 2010, 03:31:59 PM »

this is not a grinder mark it is from beating the sector shaft out with a hammer. one of the teeth scarred the housing because the teeth are off centered from the sector shaft and if the teeth are not centered when removing or installing they will scar the housing like this due to forcing the shaft.

That sounds right. I filled it with JB weld and smoothed it out and its been like 2 years now and still not a single leak.

yeah it isnt on the high pressure side and the seal only sits inside the box about an 1/8th of an inch

83yotachad · « **Reply #311 on:** Jan 21, 2010, 07:57:52 PM »

Very good post! I ended up with to boxes do to not reading completely. The 1st one I have not been able to get it back together do to them little balls gerr it got me drinking. The 2nd one I got it done and installed yahoo! I read some where that some one took two stock reservoir's cut the bottom off one and the top off the other cleaned them out and welded them together I have it plumped in I don't think something is wright I have so much pressure that it comes out the bottom of the cap so I took the reservoir out and connected the steering box to the pump and did not have that problem of high pressure but when I shut the engine off it over flows out of the top of the power steering pump even thoe there is hardly next to nothing in the psp before I shut it down. O a little insight to what I have 82/83 toy pickup with a Chevy 283 stock steering pump toy steering box and a 2X8 ram . I might of left something just ask ! Iam open to any ideas .

Anyone?

potter85 · « **Reply #313 on:** Jan 26, 2010, 02:04:35 PM »

well your ram is too big most people use a 6 in ram. and you need to increase the volume in your system by adding a cooler and/or cutting the resivoir and scabbing one together.

I completely drilled mine out to 5/16" then filled it with JB weld and then re drilled it to 12/64 or 3/16" i might need to go up to 13/64 because...
Well its all done and back together AGAIN! and the darn thang dont work right. If im sittin still in the shop tires on the ground it works great feels good and super easy to turn the tires. If i turn the wheel too fast or at a normal turning speed its like the power steering has gone completely out!!

I guess i should check out those saginaw pumps. cause I know everything is correct I have pulled it all apart 3 times now! This is givin me such a headache. It wont even turn as easy as a regular stock steering system.
Any one got some more input?
And i replaced my nicked teflon seal with a good one!

well if you would have read the hydro assist thread you would know that you need to run a 1.5 in ram and not a 2 in one. and you would know that 8 in is also long no matter what axles you have.

To long ? I can turn full lock to lock and not have any problems! I know jeep people running the 2x8 for quite a long time and have never had a problem. I just wish I had enough room to run an Saginaw steering box then all my problems would be over with this steering issue!

nope I like my Toyota! "O" BTW I did read the whole wright up 3 times over! At the time I had the money to buy the ram the 2X8 was the only one they had and It was local If I wanted the 1.5 I would of had to wait and it would of been $120 + shipping + everything .

I payed $110 for 4 fittings 2 hydro lines and my ram all new not used

potter85 · « **Reply #322 on:** Apr 04, 2010, 07:56:08 PM »

surplus center has quick disconnect fittings now that hold high pressure which would be cool to run out of your box just in case a line gets snagged or any other reason you would want to remove the ram

I stripped mine out as well and got it out with a "bolt extractor" set. However, now my 10MM plug is junk. Does anyone know what thread/size this is?

I was told m20x1.5 straight thread. I have also found M20x1.5 pipe plugs. This is the ONLY things stopping me from getting this back on the truck.

Thanks!

put a stock one back in and see if it fixes the whine, and see if it performs the same?

about 3/8ths on an inch down. be carefull not to go to deep. just keep checking it once you get down a little. better safe than sorry. it will be very obvious when you get to it. usually, the bit will catch a bit right before you get into the vein. hope this helps.
