[QUOTE="PA.Johansson, post: 76328, member: 9558"] Yes, the spring was in the drive motor. The shuttle valve is damaged somehow on one of the drive motors. The spring was broken/rusty and it had somehow damaged the drive motor inside where the shuttle valve is moving. I don't know if this is possible to repair somehow, i've been looking at loader parts source fore a while, but if the damage can't be repaired i need to buy two new ones. So, today i put a new hydraulic filter and changed the oil. A local hydraulic firm told me to try regular 10W engine oil since its thicker than the 10W-30 universal hydraulic fluid i've been using now. I started the engine and it was totally worthless now. I tried to drive if for a while and it did only get worse, i also tried to remove all the air from the hydraulics but there was not any air in the fluid. No bubbles, no nothing. So my question now is, should i use the 10W-30 universal hydraulic fluid instead of the 10W motor oil? the motor oil was worthless. The old filter was filled with dirt, i'll check the new filter if there is anything there now. with what should i cap the large hoses? [/QUOTE]
