Wrenching on the.......

[always-learning]

Stole your idea, Gregski.

For some time now, my yoda's PS pump has been seeping out the back. Since today was a good weather day, and I had no work scheduled, I figured I'd take on the task of fixing the leak. Since I enjoy wrenching on my own vehicles, this was actually fun for me.... for the 2.5 hours it took to get it back on the road.

First I pulled the pump out, and removed the crud from the outside. I disassembled it and cleaned all the parts. I installed all the new seals and recommended parts to replace, and put it back together. So far, no leaks and I saved myself a ton of $$ doing so.

Originally, I was going to swap out the leaker for a reman or New pump from Toyota. Since they wanted $500 smackers for the pump, I figured I'd look for a reman kit on the net. I found a dealer that sells the kit (toyota kit) for $39. shipped to my house. It went smoothly, although the inside of that pump is much more technically advanced that I had imagined. There are little steel plates (look like chicklets in the pic) that move in and out of a rotary hub against an oblong retainer.... giving it pressure. Ingenious design and I had fun doing the job myself.. and saved a few $$ in the process.

Here is the pic of the engine with the pump removed, and the parts lined up on a worktable ready to be rebuilt. You can see the 3 main seals that are to be replaced (look like 3 broken circles,. along with a few others.

Here's the pump re-assembled with new parts, and then reinstalled.


I love working on technical stuff and having it all go back together without issue.


Fun day..... although I should have powder coated it blue, or green to make it stand out !

Chrome plate ?

You guys with wrench skills have my envy. Woodbutchery is my limit. I did rotate the tires on both of the vehicles here yesterday, and I usually change oil also. My wife needed new wiper blades and I told her she should go to NAPA, ask which kind to buy, and ask the guy to put them on. I could not figure out the mechanism..........

Nice fix and if it was 15 years ago I'd have done the same.

Sold all my auto tools last year from 15 years of non use. Steering pump went in my truck last year but my extended warranty covered it cept for $100 deductible.

Sure don't miss the grease and laying on my back.

I just wish that I had taken a picture of that pump mechanism... It was really cool. It uses centrifugal force on those little black (chrome in real life) metal pieces. They fit into their respective slots on the gear, and when the gear is turning, they are forced outwards towards that oblong retainer. I'm in awe of humans who engineer such things.

Here's the best I could do.

Sounds like some type of a planetary gear system.

If that got your interest, take apart an internal multi-speed Sturmey-Archer rear bicycle hub.

Here it is....

Damn, I'm freaking fast.....


I put it back together and I'm riding down the road on the bike already !


Superman fast ! ;-)

I rebuild a few of those back in the day...I felt like my eyes were going to explode.

[GaryJR]

Yep that's it, there's also a 5 and 7 speed version. Rebuilt plenty of them years back when I wore another hat.

Chucky should try an automatic transmission. between the front pump and planetary sets, he'll be beside himself with joy :-)

I got to agree that you guys that can work on your trucks have my envy. It is an especially bitter pill for me to swallow since my dad is a retired mechanic. Besides working on his trucks he often is helping rebuild some guy's tractor or hay baler or some thing else. I can out build him but I never did pick up mechanics. About the best thing he taught me was that a paint tarp was not for painting on. I cannot tell you the number of times we were repairing a tractor in the middle of a field and before he started taking things apart he would spread this paint tarp on the ground under where we were working. Sure saved us looking for the dropped bolt or nut that fell into the dirt or grass.

He does not do as much as he used to but at 80 I should guess not. I know he still has an awful lot of tools but without the computers to hook the engines to I doubt he can do lots. But he still changes his own oil, will take a day to rotate his tires, does his own brakes. One thing too, my folks drive way more than I do. They are constantly heading off in the truck to go to some farm auction, head down to Branson or up to Iowa. Cannot get them to come to St Louis but they run around a lot. They are enjoying their retirement.

...my dad is a retired mechanic.

Mine, too! I learned a lot from him about auto repair over the years but probably only retained 20% of his total knowledge. I think I broke his heart when I told him I preferred sawdust to grease.

[Randy Bush]

My Dad is a machinist and mechanic with his own shop 45 yrs, is going to be 80 this next year , but is still running the shop. So I grew up doing that to , just got tired of it and decide to do the construction/ remodeling 15 yrs ago.Still work on all my own stuff and a few friends. got one of my diesels to rebuild and also rebuild a 460 and put it in a 79 F- 250 4x4 this winter hopefully. So will have greasy hands again.

Ok... a new chapter to the story.


Wife's SUV Yoda. About 95K on it, and it's almost 8 years old.

The truck was following the road grooves, too much, and the front tires were scalloped at the outer edges. For sure, I thought that the outer tie rods were bad, but came to find out that the PS rack mount bushings are notorious to go bad in these trucks. I called the dealer, and they said the rack was about 1k and the install was a few hundred more. They said that they do "NOT' replace bushings but change out the whole rack. I found that ludicrous.

Went onto a Yoda forum and found that Energy Suspension makes Polyurethane bushing kits for these trucks for $20. Had it shipped to my house, and it took about an hour to replace the 3 bushings.

[always-learning]

Here is the center bushing being removed. It was the most difficult of the 3 to do because the bolt head in up above directly below the oil pan / tranny. Took longer to get the bolt out than it did to to the whole install of new.

The bushing on the left was the main culprit, as it's supposed to prevent sideways movement of the rack, as you turn the wheels. Since it was worn out, it allowed the rack to shimmy horizontally and destroy the outside of the tires.

Straight as an arrow now, and I saved over a grand.
