Firewood Processor Hydraulic Questions

[SweBota]

Reg HP ratings, even if they are correct, they are instantaneous values. Small engines will never last if you aim to load them down anywhere close to the max ratings for any longer amount of time.

Driving a hydraulic machine is HARD work, thats why we need to oversize the engine.

.58 ci saw motor at 650 PSI = 60 in/lb
!

Is that the size hydraulic motor you are planning on using????. What kind of motor is it, Gear? you might want to rethink the size before you buy, I think the motor is way to small for a saw

Is this the motor you are considering using, 0.58 cu in PARKER MGG20025-BA1A3 HYD MOTOR. If so, I have read several processor builds that chose that motor, and all the builders complained about not having enough saw power and eventually had to swap the motor out for something larger. The advertised torque numbers are based on 5000rpms, when sawing wood, the motor doesnt have the power to maintain that speed. Another thing you might find out the hard way is the shaft lenght isnt long enough to pass thru the pump mount and still put a sprocket on it, just something else I have read about and dont have any actual experience with.

Did a little math, ouch!!! Anyways, running 17gpm of oil thru that motor will result in a speed of 6771rpms, and the motor is only rated for 5000rpms max. Motor wont hold up, you will endup blowing the seals. I am going to suggest you go with a bigger motor, 1cuin at least and use a bigger sprocket to run the chain. The bigger motor will give you more hp and torque, but less speed. The larger sprocket will increase the chain speed.

Glastron23 I am going to build a processor I noticed your post about a triple Salami sectional pump could you give me more info on this like the name of the pumps used to make this sectional pumps .

I am interesting in seeing how the .58cuin motor worked out for you

Firefighter222, If you haven't already, you might also want to PM Glastron23 to see if he answers there.

Muddstopper, Not much has changed since last year. Well, we haven't run any more wood since last year. We set the processor back up a week or so ago and found we have a cracked weld in the oil cooler. This could be a blessing as it was severely undersized and needed to be upgraded. Hopefully we will get reimbursed for the broken one as it is less than a year old.

I'm thinking of going with the Cool-Line or AKG C-48 which looks to be the core of the thermal transfer coolers. We'll get a low amperage draw automotive fan to cool it, or maybe another box fan for the short term :ashamed: Given how hot it is, we can't do much until we get it replaced.

I'd still get the .7ci motor to replace the .58 if we were to destroy it.

Never ending work when you build a one off project. Always something you wish you had done or done a little different. glad to see the little .58 motor is working out for you. I had read a couple of threads on another forum where the .58 cuin motor was the first thing that got replaced on their processor builds. I cant remember for sure, but believe they also stepped up to a .7cuin size. anyways, its whatever works that counts.

Been trying to get back to my build. Torn rotator last sept and now a knee replacement has pretty much kept me out of the shop. Hobbllng around pretty decent now and been doing some tinkering with my tractor, but its too hot to want to do much.

How do I find Glastron23 info to PM him I have never done that before Thanks

 

[Wild Bill the 2nd]

Simple as clicking on his name (handle) to the left of his last post and then selecting "Private Message"

Hopefully he will get back to you. If he doesn't I can at least offer that Salami is a brand of Italian made pumps that can be connected together to make double, tripple, or quad section pumps. you can find some more info by googling "Salami hydraulic pump"

I have started the processor build I see on you info sheet for the saw you put down in the notes section for the motor a 15 tooth sprocket and then in the discription you put sprocket 16 tooth ,404 ,.080,JA. Is the 16 tooth the one you used ? I bought the same Parker Motor from Surplus Center as you did if you could let me know the parts you used to make the chain move it would help me thanks a lot Peter

 

[Wild Bill the 2nd]

I did in fact end up going with the 16 tooth sprocket. The 15 wasn't stocked, and well, the 16 toother will get you greater chain speed.
Not sure what you mean by "make the chain move" I got a JA sized QD bushing from McMaster Carr (part # 6086K118) to mate the sprocket to the motor shaft if that is what you are talking about.

If I remember correctly the keyways were not the same size and we had to machine out the bushing from McMaster.
