HERO Maker Posted October 24, 2016 Report Share Posted October 24, 2016 Thought I would start a new thread on this part of my project to change leaking pressure hose. Noticed the gasket was leaking a bit, and decided that this was a good time to tackle this as well. I have all 4 bolts off of the top of the steer box and tapped it with a rubber mallet and it spun clockwise pretty easy. It now is spinning itself apart in a clockwise motion? Is this supposed to be the way to remove it, or am I about to have everything in the bottom half of the gearbox fall apart, and then I would be really up a creek without a paddle?

CDR Posted October 26, 2016 Report Share Posted October 26, 2016 I don't know Volvo, but most boxes get rebuilt not resealed. The tolerances get so bad it causes the seals to leak.

HERO Maker Posted October 26, 2016 Author Report Share Posted October 26, 2016 730,000+ miles. No seals are leaking just the gasket on the top end. Was needing to change out 1 leaking hose, decided to change all three, and then thought maybe I should take care of the slowly leaking gasket. Not getting any answers regarding pulling the top half and shaft out of the body. I am worried about what might fall apart inside the body, or be left behind like ball bearings! But no one is giving me the facts of what happens if I pull it out. So using so gasket maker and putting it back together today. I expect it will leak some, but will turn it over to the mechanics when I get to the valley next month.

I'mdonewiththis forum Posted October 26, 2016 Report Share Posted October 26, 2016 Rocky, take a look at this PDF and see if it is similar. STEERING GEAR BOX If you mean the over center adjustment, the center stud is screwed into the cover and is attached to the shaft underneath. It will raise and lower the shaft to make the gear 'lash' tighter or looser. To pull the cover on the boxes I have dealt with you need to pull the pitman arm and make sure the shaft is clean. Pul the four bolts and the cover and shaft will pull straight out.You won't be getting into any of the ball bearings so it is no problem. You do need to be careful that you don't get the adjustment too tight because that will cause accelerated wear. Just keep in mind that my experience with steering gear boxes is limited to the type on my Dodge....... Link to comment Share on other sites More sharing options...
HERO Maker Posted October 26, 2016 Author Report Share Posted October 26, 2016 Trying to post a photo of what I have: Thanks for the PDF file, but it doesn't look like what I have. My shaft that connects directly to the steering column, rotates with the top 1 inch of the box. If the picture showed up, you can see where I removed the 4 bolts around it. It moves very easily to the right (clockwise). Rocky & Sheri Rhoades '01 Volvo 770 2016 DRV Mobile Suites, HoustonHERO Makers Ministry Link to comment Share on other sites More sharing options...
Chad Heiser Posted October 26, 2016 Report Share Posted October 26, 2016 I had an issue with leaky seals in my gearbox. I had my mechanic put new seals in. It stopped the leaking for about a year and then it came back even worse. I finally just bit the bullet and put a new gear box on. No more problems since then. I know this doesn't help with your question, but it may help in the long run if you run into the same issues I did. The gear boxes are pretty standard across makes.

HERO Maker Posted October 26, 2016 Author Report Share Posted October 26, 2016 Thanks Chad. Trying to track down what the tourque amount is for the 4 bolts now. If this "fix" was to end up stopping the leak, then great! But will probably get the whole thing replaced when in the valley this winter for the mission trips.

jkennell Posted October 27, 2016 Report Share Posted October 27, 2016 In all the years I've been a farmer and worked on all my old stuff...don't think I've ever had a steering gearbox apart! I've adjusted a couple...thats it. Just not real common knowledge how to take them apart. No camper at present. Way too many farm machines to maintain.

Yes, I'm not thinking about taking it apart now. Just getting it put back together (with I'm sure a little seepage) and get a whole complete replacement. It's only $$ - and work.

Scrap Posted October 28, 2016 Report Share Posted October 28, 2016 Sorry Rocky I had no time but I wanted to get the manual out. Hopefully it is the right one as the Volvo one is mounted inside out from my world and it throws me off. There is a lot of stuff behind those four bolts so I think you made a good decision to glue it back together and press on till you get 'home'.

HERO Maker Posted October 28, 2016 Author Report Share Posted October 28, 2016 Scrap, you're right. That manual scared me into thinking straight on this project! Too much to go wrong, and I only have another week to get the rig moving again! Will let you know how it all ends up tomorrow when I get some fluid in it an crank it up. It only has to make it a about six hundred miles. Who knows, I might have fixed it!!!!!!

HERO Maker Posted October 29, 2016 Author Report Share Posted October 29, 2016 Well, after using the gasket maker in a tube stuff, I needed to let it sit for around 1 hour to set up, and then I could torque the 4 bolts down. I was able to determine, using Scraps PDF file, how much torque to use. Then I must let it sit for 24 hours before adding back the fluid. Added ATF yesterday and started the truck up. Worked the steering shaft back a forth a lot and everything moved as it should. But there was a lot of groaning (like what I heard at the Rally before discovering I had a leak), so checked for any leaks. Not leaks but some of the fluid had dropped a little lower in the reservoir so added some more. I did not drain the whole gear box, so I was only adding what had been in the hoses, reservoir and pump. (took about a total of 2 quarts) Fired up the truck today and by grabbing the shaft I was able to turn the wheels to their stops both ways, but still had a lot of groaning. Took it for a ride (about 10 miles out and back) and shut it down with a lot of groaning still going on. Checked the reservoir again and it was low! Filled it up and all groaning has departed. Must have had air in the box, but didn't bleed it out. Nothing explained about how to bleed the air (if I even had some in it, since I really didn't take the box apart) or how much ATF should go back into the unit. Even checked the original service manual I have for the old truck. It says what to use, but doesn't give capacity in the capacity section of the manual. Still no leaks, and nothing from that top seal around the shaft (which I didn't touch), so we'll keep monitoring it in the future. Hopefully I escaped a big $$ item and made a simple little hose change project last a lot longer and learned a lot through this project. Like needing to remove the alternator in order to get to the high pressure hose, and then how to reinstall the alternator (not fun).

HERO Maker Posted October 30, 2016 Author Report Share Posted October 30, 2016 I'm glad I could actually work on it myself! Didn't have to crawl under my steering wheel, and get contorted into twisted positions (like you did for me) and that made me thankful.
