Hydro Lift Initial Findings

[Austin]

Decided I should get an early head start on some of my “winter” projects. Got everything disassembled the best I could today, but with my vice still not mounted down getting the ports and the bolts with valve/spring/ball out of the port “block” did not happen. I was unable to even move the ports and they started to slightly round-off. Everything looks fairly clean otherwise but the o-rings and seals were definitely all bad/going bad. The oval/rectangular-like o-ring was as stiff as a rock, when I bent downwards it stayed bent.. Thankfully I have all the normal o-rings to install (thanks to @GregB). Another plus is that the lift cylinder itself was not leaking or even barely wet so I will leave that alone, though I do have the o-rings for if. I’ll probably regret it later but it’ll be my own fault.

 

Now for the questions :

 

How should I go about getting the ports out ,with keeping in mind that they started to round-off?

Where can I find the two oval like o-rings? Local hardware store??

And where can I find the pulley-shaft seal? (The thick seal for the shaft driven on the engine) Again maybe a local hardware?

Austin,

Have you studied this article?

In it Kirk used regular o-rings for those oval ones, said a #34.

When I did my rebuild I bought the pricey kit from parker and they came with the kit.

Also make sure while it is out you look at the pressure relief pin, it is shown in the article.

A pin with a tapered head and the spring.  The conical surface gets a step pounded into it.

So it could need the spring shimmed, cleaned up or re-made.

The clipped packet under the envelope in the first photo is a print out of that write-up. I have it but have not read through it yet. I suppose I will stop at my local hardware sometime soon and take the castings and old o-rings/seal to match new ones. I will take a look at the pin, but minus the severe leaking the pump worked extremely well. Next time I have a chance I will update this post with more findings.

here is a snip of the pump kit I bought for mine.

But when I did the rebuild kit was only $73

A hardware store probably won’t have many o-rings to choose from. A hydraulics specialty shop would be more likely.
