steering box overhaul

Post by ppeters914 » Sun Apr 23, 2017 2:52 pm

Searched the TechWiki and forums first.....mentions of folks doing it, but no details.

My steering and idler boxes appear in great shape; little to no play..... wooHOO! I'd like to replace seals and gaskets (surprised no one has posted a list of items...maybe it's obvious), which means pulling the arms off the shafts.

Any tips before disassembly, i.e. things to note or punch mark, etc.?

Thanks.
Pete

Yes, a good idea to punch orientation marks in the relevant shafts and arms.
From memory, the splined shafts on my '65 SP310 were tapered and required very little effort from a pitman arm remover to dissemble.
Undoing those big mutha nuts might be a challenge if the boxes are no longer mounted to the chassis.
Mine were shot and I had an Auto Trans Workshop recondition the shafts and hone the bushes to suit.
Nissanman, just trying to help.

-A big bench vise comes in handy when removing the lower nuts.

-You don't really need to mark anything, but it can't hurt. The pitman splines have a larger spline every 90 degrees IIRC, meaning you can only put the arms on in 4 orientations

-The lower seal on the idler side is meant to be compressed at all times. You'll know what I mean once you see the seal. Since the idler side rides on a threaded shaft, the shaft will "ride" up and down ever so slightly as it rotates. You'll have to index the pitman arm on the idler shaft to get the proper compression on the seal. It's not hard to figure out.

-The worm has o-rings on both end plates, plus a small seal that the input shaft goes through. It's all very easy. Steering box lower seal is just a seal and not like the idler side. It doesn't need to be compressed. The top cover gasket is paper and one can be easily cut out of gasket material.

-When removing the steering shaft from the worm box, be careful that the roller ball does not fall out of the housing. If it does, the needle bearings could fall out, and it's a pain putting them back in.

Yup......that, and a 3/4-inch drive socket set!

Hmmmm, I didn't notice this at first, but my more knowledgeable friend did. Mine looks like there's two rubber washers (only see one listed in the parts manuals) that are a little "loose" at the end of one rotation, and snug when rotated fully the other way. We decided not to pull the arm to replace those, but now you have me rethinking that.

The space between the arm and the end of the idler housing may change, but there should be a seal in the bottom to keep the grease in, correct? Wonder if the two washers I'm seeing were added by a PO at some time.

So I discovered. The seals are still in the Nissan stock system, and cheap. I'll go to hydraulics store to match up the o-rings, and cut my own top gasket.

Getting the arm off the steering box required heat and a press. In the process, we learned about the peg needle bearings......spent 30 minutes with magnets before finding them all. :smt013 Interesting that Rallye says there's 38 (matches my count), Scheeler's Roadster Book says 40, and the Nissan manuals don't mention them at all. Regardless, can't wait to reinstall those. :roll:

Yet another example of an answer to a question I never knew I needed to ask.
That's what makes this forum so fantastic.
Now, I know, if I ever get to that point, that there is a thread that I may look back at.
Thanks.

Could have to take up space, but, if you thread the idler shaft in a little bit, you don't really need the washers. The top of the pitman arm should contact seal.

I had 38 needle bearings as well. 19 on top, spacer, and 19 on the bottom.

Suggest adding a paragraph or sentence about using wheel bearing grease and a wooden dowel to
hold the needle bearings in place, in the unlikely event they drop out inadvertently.

Would be nice to see a few pics or a video if someone is doing a rebuild.

I'm busy to rebuild my steering box with new bearings and new oil seals. It's an early type.
The oils seals I found replacements for in the tech wiki, but are there for the NSK BT18-2 bearings also replacements?

Geez....has it really been two years? :(

Finally back to this. I have 1/64-inch gasket material. Think that's thick enough?

Today I learned that you can put the worm shaft in backwards. Yup, it's true. The bearings and cover bolt patterns are identical making it easy if one isn't paying attention.

:smt013

Notice the taped up shaft on the right? Should be on the left. Luckily, there's just barely enough slack to lift the peg out after removing the top cover. Really wasn't looking forward to pulling the steering arm off. Still have to wait another day for the paint that covers my repairs to dry before installing.

Anyway, triple-check before you button it up.

Hey, Steve, might want to add this to the TechWiki.

Cheers.
