HYDRAULIC FORUM FEEDBACK

[J_J]

I see lots of hydraulic questions about information on how to fix or install something, and recommendations for hyd components.

A lot of people are providing good logical answers and helpful info, and then a lot of them never respond to the info given, whether it helped solve the problem or not.

I believe the reply's to the data given, whether the info helped or not would at least let us know that we did provide correct and useful info.

Most of the data provided will probably save you lots of time and money in your endeavor to keep your tractor in working order and improve your operating potential.

Not looking for thanks, just a reply to the data provided, was useful or not.

J J- I always enjoy your posts. They are amazing in the detail and speed you respond. I always read them in detail trying to learn. Just yesterday you gave a good explanation on open and closed centers. A bunch of it is over my head but I am trying to learn. I can see that it would be nice to find out the final results from the advise people gave.:thumbsup:

I totally agree that persons seeking diagnostic information of which I will gladly give should report back as to what actually solved their equipments problem.

J.J. -
I agree and wish more people would provide follow-up in every forum. I actually consider it a duty to let people know how things worked out when I've asked for their help. Call it good manners or just a plain thank you, it doesn't take much time. As you state, it is extremely important from a data gathering standpoint.

Perhaps a note from Muhammad in the monthly newsletter and a "sticky" for new members would help. Without a doubt the greatest benefit of TBN for many of us the help we get in fixing/solving problems. Feedback can only make it better.

Agreed. It would be helpful to know how things worked out for future reference

I agree. I know sometimes when do a search I find lot's of threads with no outcome. Very frustrating when you are in need of answers.

I've been guilty of doing exactly that. In my case I don't post unless I've got something constructive to say, ie, I'm not one to add ditto marks for sure. As far as any information I've received regarding hydraulics or anything for that matter has been spot on and appreciated, so accept my apologies for running off to the next of my problems and not acknowledging the last one fixed.

I have to agree with JJ

As a manufacturer technician who used to advise a world wide network, when we gave a dealer a fix to a technical issue, very few people ever came back to say that our solution fixed the problem!!

It is nice to know that the advice , freely given has helped fix an issue and get a customers machine back working!!

Good point JJ. Follow up would help those replying & ALL others reading. I appreciate reading your suggestions and I think I remember cyrush with some good one's as well...... and now that I might have both of you guy's attention, In theory (hyd) can/could you have a pump/motor combination that made equal input/output in rotation? That is how close can this be (assuming all HP, cooling, etc. is available) to 1 rev. of a pump = to 1 rev. on a motor. I'm thinking a low rpm situation. Sending horsepower through a "hose" fascinates me (hydraulics) and I wish I knew more about the math and the hyd. symbols on a drawing. Sorry for the slight "hijack" JJ.

Rustyiron !!

In theory it is possible to have a system where 1 rev in = 1 rev out but in practicethis does not take account of pressure, temperature, leakage and slippage??

As temperature and pressure raise then the possibilities of leakage and slippage between the pumping element become greater particularly if relying on gear type pumps and motors. A more accurate system would use something like an axial piston pump and motor and this gets rid of the slippage problem.

With a rise in temperature the fluid becomes thinner and more likely to leak , same applies with pressure, and again on the motor if the load increases the torque to turn the motor increases , ie pressure goes up so system becomes more leaky.

IH with their hydrostatic transmission use a pump of given capacity matched to a motor block about 2 sizes larger to give an effective gear reduction across the hydro unit.
