If you have done a compression check the next step is to take off valve cover and look.
a broken valve spring could be the cause, or a lifter. Start by checking the compression for the number 8 cylinder, then remove the valve cover to inspect the rockers and lifters.
If the spring is not physically broken, it is probably still good.
Take off one of the valve covers, if the rocker has a roller tip on the side which it touches the valve spring then its a roller, if no roller tip is present then its a normal tappet rocker.
If they're spring brakes, you won't be able to get them to release. The brake chambers won't actuate when you push on the treadle valve (brake pedal), the brake control valve won't remain pressed in.
Take the valve cover off of one bank of cylinders, have someone turn the engine over, and watch to see if the cam is turning. If not, the timing chain or belt is broken.
Only by replacing the wiper arm can you change the tension. Rarely is this necessary unless the spring is broken. You can easily tell if the spring is boken. No tension on the blades and the spring is broken. Try replacing the entire blade assembly with a new set of quality blades. Trico are inexpensive and very good.
Remote is not transmitting, codes are not set the same, receiver is not working, motor burnt out, no power to motor, drive chain jammed or broken, counterbalance spring broken, etc. No way to tell at long distance.
use a piece of modeling clay,( you can get any wal-mart craft section). place on top of the intake valve relief . place the head on the motor with a few bolts and with a week spring and your valve in place, compress the valve and measure the clearance with a dial indicator and this should tell you thickness of the head gasket you need.
Unless it is an electronic governor on the turbine, there is a mechanical overspeed trip device which closes the trip valve (or trip throttle valve [TTV] on small turbines). This device is a spring loaded weighted pin set into the turbine shaft. At a particular set speed (110% of maximum operating speed, typically) the pin overcomes the force of the spring, flying part way out of the shaft and striking the trip mechanism linkage. This linkage up to that point was holding the trip valve open, now with the release of the linkage the spring on the trip valve instantly closes the valve stopping all flow of steam to the turbine. On electronic governors, when the set point on the turbine speed is reached it opens a solenoid valve (which requires a manual reset) which dumps all hydraulic pressure from the trip valve, allowing it to close.
You can tell a bad valve by doing a compression test.
If its broken it won't work
no you cant
