SOURCE: my excavator hitachi ex200-1 weak swing and when you swing then stop vibration begin on turn table when i stop to swing,and when i swing and lift cylinder raise,vibration on the turn table will contin

Not sure would need to have a good look ,but i suspect a safety valve isnt closing properly causing thumping within the hydraulic system which is the vibration you can feel,shouldnt cost a lot to repair providing the faulty valve can be located so return to the dealer as they will have a good idea as yours isnt the first to go wrong iam sure

Hi Rodney:
Sounds like an excavator with a bad pump.
Time to call a service technician (mechanic) who knows the machine.

Why does my boom on my 325 bob cat excavatoe drop quickly to the ground on it's own.


You need a new valve block assembly thats all inside the assembly is a restrictor valve to prevent this but on the old plant i worked on 40+ yrs ago it was allk mechanical and repairable but new stuff is predded together and not readly repairable like the old gear from my youth

i used to know some one that had a hitachi. was always having problems with it not moving. if i remember right it was the brake leaking think its air system and it was just leak. he had it fixed and added an air line indicator fitted think the boom works on the same system. if i remember right there is a foot brake and a lock brake lock brakes hydraulic . and the normal braking. but in the event of the air brake falling the hydraulic brakes take over. but this is from memory and it was a long time ago you dont see meany round here any mor they all jcb's and other makes.

I cleaned the egr valve on my 1996 Altima and now it barely runs and smokes. The egr valve moves freely and seems to work properly?


it may be moving to freely as it should have some resistance from the piston inside.if the piston moves to freely it will open strait away insted of move slowly up and dow with the speed of the engine.
