Excavator hydraulic pump full rebuild...Can it be done by an amateur? (Hitachi EX120-2)

[@pabohoney1]

The "extra" oval o-ring looks like it's supposed to go under the front cover of the pilot pump. You can see the groove and the corresponding mark where it sits.

[@PacificNorthwestHillbilly]

Yup, I missed that...good catch

You have put more quality time in the rebuild than any shop would ever do. When all is done you will know you have done a perfect rebuild like you did on the dozer.

[@johnalexander4356]

Congratulations! That was a major accomplishment and a very intricate. I spent 30 years supervising an aviation rebuild facility for the military including an hydraulic shop that did major rebuilds. It takes a very skilled person to do what you've done!

Funny story: We decided to raise chickens and had a dog that loved to play fetch. We let the chicks free range. My dad was working on the car one day, and the dog wanted to play fetch. She would drop her ball at his feet, and he would mindlessly pick it up and wing it for her. Well, a chick roamed into the area as the dog dropped her ball. My dad reached down and picked up the chick and threw it, and after he released the throw, he realized it wasn't the ball. 😂 The dog ran after the chick and very gently caught it mid-air before it could hit the ground, carrying it back and placing it before my dad. Unharmed. He never threw the ball without looking at it after that.

[@jayc4562]

One of the most important things is cleanliness. I ran a aircraft hyd shop for 17 years. If you keep it clean and follow the technical data it is like any other job. Use brass seal picks and stay away from scratches. I have used jewelers rouge to polish and lap.

[@TechGorilla1987]

@19:24 - It's cool to watch a thing get rebuilt with decent-ish parts and extreme attention to detail. There are a lot of "fix it cheap" channels, which, for the record, I like too, but your method is also most satisfying.

[@PacificNorthwestHillbilly]

just wait till I add in a transfer case to drive the pump

[@dadgarage7966]

I've worked along side a lot of "pros" who did things like fill a brand new Gardner Denver screw compressor with oil using an improvised funnel from a scrap of cardboard that was lying on the floor. Or use the hydraulic oil drum pump to pump out a caustic soda tank and then put it right back in the hydraulic oil drum. Be glad you're an amateur.

[@wrstew1272]

Noticed the bright red squirt can, 👍! Makes sense with the price of brake cleaner, and you know beforehand when you are getting low. Everything seems to take longer when you aren’t working at a full time shop, I’m a past tense professional and working at home and don’t have specialized tools for seemingly small simple projects everything seems like it takes four times longer than when I was punching the clock. But now I’m allergic to clocks😂. Great to see the progress on a very complicated series 😊.

[@RegWhite-g3u]

Loved the little duckling he's so cute

[@markamcampbell5795]

I rebuilt one of these pump after attending you tube university. It turned out great except the people didn't want to spend money on new parts. Got to back together and it worked great but i told them no garentees. It is still working, never got paid.😢

[@johnbullwinkle4111]

You do such a great job with your parts. You clean them up and put it together looks great.

[@aguiaia1]

"It's not that complicated, you just need to spend a lot of time with it" My man, that was over 50 pieces (I'm not counting) mounted in easily over a 150 steps (really not counting), with several torque and quality checks (seriously, I refuse to count) that you disassembled, cleaned, resurfaced, rematched, replaced and reassembled. Seriously, I love the humility, but that's the DEFINITION of complicated.

IMPORTANT: PUT OIL IN THE HOUSING AND LINES. Pump will seize if rotated without A LOT of oil. I did a similar job once on a big Parker pump, on that pump the valve plate is flat, the barrel rotates on top of it and the piston's ball end in mounted on the swash plate. The pump had been eating dirt (blown filter). The valve plate had 1mm scratches in it. Been laping on a flat stone for a few days hahaha
