....back in the saddle again....
I just did my power steering pump this weekend, it was pretty straight forward
ok, that's only mostly true...
first: I was forced to do the job by a hose blowing off of the steering box. It was the low pressure side, but still got fluid allllll over the engine bay, hood, fender, motor, pump, etc
Yuck.
Once I got most of that cleaned off (mostly), I still had years of grime on the vacuum pump and steering pump that needed to get scraped off so that I could access bolts without eating too much atf/oil/dirt gunk.
then, I didn't have my fsm and was mistaken about which bolts to remove, so I pulled two of the three bolts that hold the two halves of the pump together.... you can't get at the third bolt, really. which was good, because it helped me realize that I was doing it wrong.
Oh, also, getting the hoses off of the pump is not convenient. things like the IP and the steering stabilizer make it a little tricky to spin wrenches in there.
finally did get the pump off, and cleaned it up and broke it open on the bench.
first thing that was *definitely* not right was that the 12pt nut on the shaft had worked itself loose over time and at the end of the shaft, where it had basically stripped itself and the shaft. getting it off wasn't too hard, and fortunately I had ordered the shaft when I ordered the rebuild kit
the old shaft had some pretty good wear from the seal, as well.
also- getting the gear off of the shaft took a little bit of work with a slide-hammer gear puller thingy. It would have worked much better to use a more appropriate tool.
Unfortunately: when I ordered my rebuild kit, I got 2 kits (one for me, one for gifu) and one of the kits that came was the wrong kit. I got prompt service on getting a replacement kit, no worries. however, I seem to have kept the wrong kit near the top of the pile and so I managed to have the wrong kit on-hand when the pump was torn down.
the right kit is buried in a box somewhere because I'm part way through moving house. shucks.
so the project got put on hold (and the pump got a fresh coat of paint).
fast forward to day 2.
I found the correct rebuild kit and got to work on the pump again. Unfortunately, I didn't get a replacement nut on saturday when some places were open.... so I tried to find one on sunday. that didn't got well. that nut is very large (14mm ID?). after failing to find it for sale, I did manage to find a replacement by digging through a 5gal bucket of bolts and nuts (thanks to gifu). problem solved.
I should mention that on saturday I did buy a new bearing. Napa had it in stock. part number of the old bearing was 6203z, I think. I'm pretty sure. but this is from memory.
anyway, after getting the new bearing onto the shaft (not that easy), I had trouble getting the shaft and bearing to fit into the space where it needs to go.
as it turns out, the oil seal sits pretty low in the housing. lower than flush. once I got it seated all the way, the shaft and bearing weren't so difficult to put back in. I used a tapered punch in the center of the shaft, and a deadblow hammer to seat the bearing all the way, after coating it with atf. No worries.
then I had some issues with the little woodruff (?) key that sits in the shaft and holds the gear. apparently something had changed over time as the key was just a little wider than the slot in the shaft. I sanded the key down (after spending 20 minutes cleaning/fitting/fiddling/scratching my head) and it fit just fine.
then the gear went back on, but also didn't seem to seat far enough. finally got that settled into place. due to operator error, I marred three teeth on the gear (vise and leather glove is not a good solution when using impact.... better to use wood, or to hold gear with glove in hand. Lesson learned). so I had to clean up the gear teeth with a file. the 'damage' was pretty superficial, but time consuming to fix.
*finally* got the whole thing put together (with red loctite on the nut this time) and got it back into the motor.
had to redo that partway when I forgot to re-route the high pressure line before attaching the intake tube (you'll see what I mean when you get there)
on my motor swap, there isn't much free space down there, so the high pressure line runs very close to the pump.
ok
for real
Now it was time to put the hoses back together
except that I needed to cut a new hose from the pump intake to the reservoir. that's a large hose (5/8" ish) and the high quality gates hose that I had was really (really!) snug. getting it back together was a bear.
and getting to the hose clamp on the pump intake tube is a challenge.
but we finally got it done, and the improved pump is quieter and smoother and all-around, better.
