My sewing machine started making a clunking noise


Try a brand new needle. A bent, dull, or damaged needle will cause havoc. Changing the needle frequently is necessary to keep the machine functioning well. It is a "very" inexpensive fix for a lot of sewing machine problems.

Is there an adjustment to increase hydraulic power on Komatsu pc35mr-2 mini excavator? Or is there a sensor that is responsible for relationship between engine rpm and hydraulic operation?


you assumption is right
the pump is operating at idle as at full rpms and is controlled by pressure relief valves
When demand for pressure is low the valves will be partially opened and will operate when the pressure is reduced ( ram valve is moved)
Higher rpms maintain the pressure for faster ram operation
I would suggest that you have the system pressure tested by a service centre as it could be a malfunctioning valve (solenoid) or a failing pump

How do I remove the engine on a IHI 35nx mini excavator to rebuild it


Undertaking that major a project, even on a "small" machine like a mini-excavator, should be done using an authorized service manual. I suspect with all of the hydraulics and other mechanicals you really want to be sure of what you're doing. If you're looking for a free service manual, I can't help except to say to consult your local dealer. An online source I found for a manual, albeit for a fee, is found here:

Ex40-2 slow on one track motor,may be loosing digging power when working hard,have change hydraulic filter and track motors oil


I am assuming this is a Hitachi EX40-2 mini-excavator. Two tests that need to be run. First is the propel motor pressure equal to both propels? Secondly, but possibly more important is to check the slow propel motor for excessive case drain. This would indicate the propel motor is worn out. Find in your hitachi service manual the accepted amount of case drain for that model, disconnect the case drain line from the propel motor and cap the line. Install another hose to the case drain port with the other end in a 5 gallon bucket. Start machine and run propel for 30 seconds. Shut off and check amount of oil in bucket as compared to acceptable amount of leakage from machine spec book. All this does is measure the amount of leakage past the propel motor slippers, which gives an indication of excessive wear tolerances. Replace propel motor if needed.

Possible problem of slow movement of Hydraulic cylinder and Travel of Komatsu excavator


hi, have u checked ur fluid and filter, if so u need to check the pressure.
u can buy a normal guage and and get a bit of pipe made up to suit ur job.
you might be able to get away by increasing the spool valve. but if ran low on hydraulic then it is a new pump.

I have an Hitachi ex40 excavator. it has started to nearly stall


I have a EX200-3 it starts but has no power. when I use any function it wants to stall. Except for the bucket function, when i use this function the engine frees up. I brought it to a mechinic but they couldnt find the problem and even made the problem worse. So when I start it up the engine sounds like there is a heavy load on it and ready to stall, this problem began and has become worse to the point I can not use the machine. Help please....
