SOURCE: Excavator circuit diagram

Hi, firstly check that you are getting power to the solenoid when it tries to run as these solenoids have 2 power supplies.
One is for bringing the solenoid in the other is for holding it in place.
Sometimes when these solenoids fail the pull in connection still works but then they fail to hold.
Sounds like your problem.
We repair these types of machines in our garage so if this dont work let me know as I may be able to get a diagram.
The engine ciruits are all the same for all these *** engines.

I would like to know what will cause a JS160 excavator swing motor mounting bolts to break ?


Hi Wongani:
I would be suspicious that they had not been adequately torqued when installed. The chabces are very good that at some point the swing motor had been removed and re-installed, and the bolts were not tightened properly.
My suggestion would be to remove the broken bolts, get new ones of the appropriate hardness, and put it back together.
Then go and play!
Cheers

How to stop water from coming in the passenger floor board


That depends upon the cause of the water. There are a few possibilities, depending upon the vehicle. See this list and use what applies as a way to narrow down the source.

1. Rust hole in floorboard. Only way to fix is to repair hole.
2. Leaking door seal on passenger side. Locate and repair leaking seal.
3. Leaking sun/moon roof. Some vehicles that have these run their drain lines down the passenger side door pillar and down thru the floor pan. Sometimes the hose shrinks with age or breaks and allow water to get on to the floor. Remove the passenger side kick panel and inspect and repair as needed.
4. Leaking heater core. Feel and smell the water. If it smells like antifreeze or has an oily feel, it may be coolant leaking from the heater core. Of course there should be a loss of coolant associated with this problem. Here the only solution is to bypass or replace the heater core.
5. Leaking windshield seal. Most car windshields today are glued into place. These glue joints can break loose and allow water to leak. Also, rust can form around the windshield seal and cause rust holes that can leak. Lastly, extremely high-powered car stereo systems that pump mega-bass can cause overpressure inside the vehicle that can cause the seal of the glass to separate.

I have an oil leak from the engine. what could the problem be


Check the sump gasket at the rear of the sump tension sump bolts. Check that the rocker cover gasket is not leaking down the back of the engine and giving the appearance of a sump leak. Rear crank seal would be another point of leak and front input shaft (clutch shaft) seal leaking. Check the engine oil level and correct if necessary and check gear box oil level and correct if necessary. If you have an auto the oil will be pinkish and indicates a torque converter to gear box seal leaking.. Either of the shaft seals will require the box removal for repair.
