Krásná práce 👍

Djákujem Pékné!

[@fricknjeep]

just looking at other channels . good show thanks john

[@michaelshakib7777]

Thank you for this detailed video. Could you send me the drawings you have of the hydraulic system?

[@stevenkmckendallsr1169]

Awesome job. Great video(s). What does your selected torque of 40 newton-metres translate into for foot-pounds?

[@enginord]

Steven. I'm glad you enjoyed the video. 40 Nm translates to 29.5 pound force-foot.

[@stevenkmckendallsr1169]

@@enginord Thanks. How the heck does one calculate that? I'm almost afraid to ask because I'm absolutely atrocious at math, but it's ovious from your videos that you're quite intellient and the Good Lord has blessed you where brains are cincered, LOL. That being said, I am very seriously thinkig about getting one of these VERY soon, and will definately be applying the caution from your video at the 25:54 min. mark. Their failure to iclude that informatio in the owner' manual or promo videos for the product is a ovbious shortfall and a disservice to the customer - along w/their failure to mention the motor's horsepower specification for the product/model, anywhere. Do you know of any simple formulas to also accurately calculate that? Thanks again for your efforts, time ad wisdom. keep up the great work ! :)

[@enginord]

@@stevenkmckendallsr1169 . the easiest way is just use google. there are many websites that will do the conversion for you from Nm to kgf cm or in-lb. In my torque wrench sheave I keep a printed chart to convert between the units coming from the 16 fingered kings leg to one measured by the atomic nucleus :)

Excellent tutorial of your fix! Good work. Have you kept your motor as a splitter or did you move it over to the press? I’m trying to acquire the log table from Yardmax to fit to another splitter of very similar design. If you utilized the motor to the press and no longer use the splitter I’d be interested in purchasing your log table.

[@enginord]

Hello Stephan. I'm glad you've enjoyed the video. I kept the log splitter in one piece. Comes handy every fall when I'm preparing the firewood for the winter.

[@stephana513]

@@enginord it’s all good! Just thought I’d ask. I’m sure after your professional repair, it’s going to hum along for years!

[@rickgramlin1432]

What size was the Allen wrench for the fluid dip stick (gage)?

[@enginord]

looks like 8 mm

[@goaro2007]

How did you compress the spring and put the cylinder in ? DO you have pictures or a video on how to do the spring?

[@enginord]

I did not take apart the hydraulic cylinder part. Sorry. I just worked on the controls.

[@goaro2007]

@@enginord But when you took the controls out, the spring is longer than the frame. You didn't need to compress it to put back the controls in ?

[@enginord]

@@goaro2007 you can see the assembly at 8:35. Not sure what can I add to it.

[@vincentquinn8030]

Do you know where you can buy the valve pin assembly

[@enginord]

try contacting these folks: [e-mail]

[@nickstevens885]

I have electric log splitter force The Pusher is broke can you tell me where can I get that part

[@enginord]

try emailing yardmax. they're pretty responsive.

[@user-sw3hf6zd1v]

Excellent Job !!! Thank you very much!! Any Idea in which direction I would have to turn the last valve you installed (16 rotation ;-) in order to increase the pressure of the unit? MIne, although only rarely used, is actually quite weak as far as splitting the wood is concerned. So maybe 15 turns would make it stronger or the other direction and 17 turns will give more torque/power? Thank you in advance from Germany 🙂

[@enginord]

hello dear user from Germany! I'm glad you enjoyed the video. If you turn it clockwise as shown on the video it'll increase the pressure. try to do half a turn or maybe 1 turn at the time. also be aware that the increased pressure can damage the unit, since the seals inside are designed to a specific pressure level. 17 turns will make it stronger. also note, when a pressure vessel fails it'll spill out all the oil in matter of seconds, so testing this would be the best to do outside.

[@user-sw3hf6zd1v]

Thank you very much for the Quick Response 👍👍👍

[@user-uv6uw5vs7q]

Where can I buy the seals

[@enginord]

which seals are you referring to?

[@gerrycochrane7842]

All

[@michaelshakib7777]

My machine works on the forward stroke but doesn’t return very well. Like it’s pushing against fluid. Do you have any suggestions?

[@enginord]

Hi Michael. Glad you found the content beneficial. Acc. to the hydraulic diagram the valve routes the oil (pressure) to the business side of the piston in normal mode, and will let it drain in return mode. I would remove the lever, and pull out the valve stem and check the o-rings. if any of them is torn that might be the culprit. When the valve is removed I'd use a flashlight to see if the galleries are free of debris/foreign matter. Hope this helps. LMK how it goes.

[@michaelshakib7777]

@@enginord Thank you. I did this and found the o rings were slightly damaged and hard. I replaced them and it seems to be working ok now. Thanks again.
