Check all hydraulic filters and check hydraulic valves. Filters is maybe not good or old, hydraulic valves is damaged or soiled. If your model hawe oil cooler check is it clean out and in!

Kobelco sk210 hydraulic excavator engine getting overheated.what is the reason?


the first thing I would check is the radiator fins for a build up of dust preventing the air flow
next would be the viscous fan hub if it has one
next would be to check if it has a radiator cooler for the hydraulic system and if it has then check why the transmission oil is getting so hot
check fan drive belts for condition and tension
Lastly have a compression test done to check for head gasket or cracked heads

What would cause my hydraulics to keep heating up on a 648g3 skidder?


Friction is usually the cause of hydraulic overheating. Every time the hydraulic oil moves through the system the moving of the hydraulic fluid against the hoses,pumps, cylinders , etc. creates friction. Any restrictions such as valves or filters can be hot spots because of the friction created as the passages get smaller the fluid moves faster creating more friction. Friction = Heat.
I would check the filters to make sure they are clean. Check the valves to make sure they are opening fully. Check hoses for any kinks or pinched spots.Try to operate the skidder at the lowest r.p.m. need for the work being done. Over revving can also cause heat buildup.
Hope this helps.

Y dose the john dear 6330 run hot all the time even after it blowen out



Engine or hydraulic system overheating clearpix.gif clearpix.gif clearpix.gif clearpix.gif clearpix.gif clearpix.gif Coolant system low on coolant in 6020, 6030, 6030 Premium, 7020, 7030 and
7030 Premium Series Tractors.

]clearpix.gif//-->
Symptoms
After several hours of work, warning system indicates hot engine coolant or hot hydraulic oil.
Situation or Problem
Coolant level in reservoir is between the "MIN" and "MAX" range but engine or hydraulic system is overheating.
Summary
Air is entering cooling system, hindering coolant flow. Check coolant level. Fill to the "MAX" line on the coolant reservoir.
Bleeding Cooling System:
The bleed valve (see Operator's Manual for location) on the radiator must be closed when the tractor is operating. Open the valve when coolant is drained or filled. If the bleed valve is left open, coolant will internally bypass between the low temperature circuit and engine high temperature circuit causing overheating. When bleeding the system, open the bleed valve and run the engine with no load for 5 minutes at 1700 rpm. Then shut engine off for 5 to 10 minutes before closing the drain valve. Check the coolant level. If level is below the "MAX" fill line, repeat this procedure until coolant level stays at the "MAX" line.

Simplicity Champion Hydraulic Oil overheating


I would have to say you will continue to have this problem until you resolve it. If it continues to overheat with an oil cooler installed, I would check to see if the pump is operating at the proper pressure.

I replaced the brake master cylinder on my 91 Lincoln Mark 7 with a non high pressure master cylinder and the rear brakes do not hold. Do I need to change the cal. on the rear also?


ANTI-LOCK BRAKE SYSTEM (and HCU-Hydraulic Control Unit)
General Information The 4-Wheel Anti-lock Brake System (ABS) is an electronically operated, all wheel brake control system. Major components include the power brake booster, master cylinder, the wheel speed sensors, and the Hydraulic Control Unit (HCU) which contains the control module, a relay, and the pressure control valves. The system is designed to ****** wheel lockup during periods of high wheel slip when braking. Retarding wheel lockup is accomplished by modulating fluid pressure to the wheel brake units. When the control module detects a variation in voltage across the wheel speed sensors, the ABS is activated. The control module opens and closes various valves located inside the HCU. These valves, called dump and isolation valves, modulate the hydraulic pressure to the wheels by applying and venting the pressure to the brake fluid circuits. Some models are equipped with a Traction Assist (TA) system. The TA system senses wheel spin upon acceleration, turns on the Hydraulic Control Unit (HCU) pump and applies fluid pressure to the appropriate rear wheel. Two additional isolation valves in the HCU will also close to permit fluid to flow only to the rear wheels. The TA system monitors TA usage to avoid overheating the rear brakes. If the system does sense brake overheating, the ABS module will inhibit TA operation until the rear brakes are permitted to cool down.

SYSTEM COMPONENTS The anti-lock brake system consists of the following components:
  • Vacuum booster and master cylinder assembly
  • Hydraulic Control Unit (HCU)
  • ABS module
  • Wheel sensors
  • Pedal travel switch

On 1992-1994 and 1995-00 a scanner is used to perform the brake bleed. But on yours, I think it's different according to the manual.

What do you mean change the cal. on the rear also? Do you mean Caliper?

Suspect hydraulic driven main cooling fan not


the fan speed could be one problem...the other problem could be wth the radiatr cores being blocked..check whether the heat on your radiator is even front top to bottom and on all sides...if it is not, clean the radiator and check for the problem

Overheating and now engine 'clicking noises.


possible causes of overheating are, dirty cooling system, clogged radiator, bad thermostat. Use only distilled water with a good quality coolant.

still overheating? have your top head checked - warped head, valves, valve seats, etc. You might need to have your engine's compression checked if it is still within specs.
