My forklift steering rod seal decided it didn't want to work for me anymore so it was time to replace before the machine goes back on a blacktop job next week.
Got most of the crud cleaned up.
Disassembled.
The seals are installed in both ID and OD grooves in this part. It's a weird design and hard to torque it. From my experiences in the field trying to tighten it up I knew that although it seems designed to be torqued with a spanner, you can't swing the spanner in that space. So I always used a filter wrench and this chews up the part and dings up the rod when it slips.
so I brought it to a machine shop and had additional grooves milled into it. These aren't indexed so they were just eyeballed because there was no need to be fussy. Here's the modified part, with new seals installed, seated on the rod. It was quite difficult to seat it without banging anything up. I didn't want to make it look easy so I missed and hit the end of the rod with a ball peen hammer and gouged up the threads. Fortunately they still worked fine.
After tightening a bit I quickly discovered my wrench needed to be modified to clear the counterweight.
I was impatient and used it while still hot (careful not to touch dust wiper) and got most of the way with that iteration before I ran out of room again. This time I made a compound offset and then called it a night.
First thing the next morning I realized my new wrench, while a nice fit, was worthless because your hand imparts an off-axis torque that unseats the hinge area of the business end of the tool, causing the whole thing to slip off the part. So I finished up with a trip to the store for some brass punches as the cast iron part is easily damaged by steel punches.
I got it seated and tested the hydraulics favorably.
Then it was time to align the wheels which was kind of a pain in the behind but I got it done in about half an hour. After that I took a break to write this up and now I need to go clean up a puddle of hydraulic oil and all the tools.
