DIY018 Lincoln Steering Box rebuild Rev B Jan 2016

Post by 59lincolnrag » Sun 9. Feb 2014, 06:42

If your car is fighting you every time you make a turn ..you have an internal pressure leak....
Rebuilding your steering box is really not that hard. You need to be neat, clean and patient.
There are a few special tools required.
Steering arm puller.
Piston ring compression tool.
As for the parts ...Basically its "o" rings, 2 seals, the one gasket and the main piston seal. You can source these parts where ever they sell Hydraulic parts.
Note that the piston seal is NOT an "o" ring.
Make sure you don't destroy the top steering column shaft seal and sector shaft seal when you remove them you need the part number.

Here are some helpful suppliers:

Lets look at the exploded view of all the parts. Thank you Sam for this great picture ....
Don't be alarmed, you can rebuild one sub-assembly at a time.

Get your vehicle safely supported. Wear safety glasses.
First you want to disconnect the steering linkage from the Pitman arm. Using the steering arm puller remove the Pitman arm.
Remove the three bolts holding the unit to the chassis.

Opps ....You might want to disconnect the rag joint first. Inspect the rag joint carefully and replace it if necessary.
I also removed the brake booster for accessibility.

Set the unit on the bench or vise and remove the 5 bolts and remove the adjustment cover. Do not change the adjustment on the adjustment screw. Just leave it alone. If your leaking fluid from there. go ahead and replace the seal ...I believe its a copper ring...maintain the correct adjustment.

Here are the sub assemblies. Im also showing extra parts so you can see how everything goes together.

Carefully inspect the casting for cracks on stripped threads....this one looks good...

Here is the unit broken down ....

Take each part clean it, replace all the seals. I would caution you if you decide to take apart the piece with the ball bearings in it. I'm just sayin....
Look at the piston at the far right ...the red paint is highlighting a crack in the piston! Naturally i discovered this problem after I re-installed the unit and had the same problem. I can whip this steering box in and out in record time...! So don't let this happen to you.
I carefully honed the cylinder before I assembled the unit.

Using the piston ring compressor tool slowly insert the piston into the bore tap down lightly with your hammer handle. Be sure to wipe some oil in the cylinder.

I hope this helps. Please use this as a guide to rebuild your steering box ......

Hello, I've got my box all apart now, and desperately trying to find a source for the piston seal. I've been working with my local hydraulic shop and as you've confirmed, it is not an O-ring. Where can this specific seal be sourced? Thank you in advance for your help!

A part number and ID of the supplier would be very helpful! I too am trying to pull a few "kits" together so other folks won't need to go through the same trouble!

Great write up above, gave me the confidence to pull that beast apart!

Give me some time and I should be able to find them ...
