    Special thanks to you again Nige .... makes it so much easier when you get experts like yourself helping a 74 yr old who can pass on these things. In my town we had real good bush mechanics but sad to say those times have changed with the computer age. I'll check back when I get working on it.

    Thanks. My next move will be clean radiator & oil cooler in front as hard to get the bottom in between. Fan OK & Belts. Can you tell me is there any pressure when I disconnect the oil cooler or can I just unbolt & catch oil? as have no manual.

    CAT 312 Water Temperature Sensor

    Just wondering if anyone has had a faulty water temp sensor & if faulty would this cause the guage to go up & the buzzer go off after 1/2 hour of running. Coolant is OK on inspection, thermostat fine & coolant not overflowing to the holding tank?? any thoughts.

    Komatsu WA30-3 loader very slow at moving

    No clutch pedal as hydrostatic --- only 2 brake pedals & accelerator? I will check hydraulic filter. Yes park brake fully released. Once its hot it runs well. Hard to get parts for these as must come in from Japan.

    Komatsu WA30-3 loader very slow at moving

    I own a Komatsu WA30-3. It starts easy but very slow off the mark. I understand these loaders are hydrostatic but need help as why it takes ages to get off the mark. Motor is fine; hydraulics work well but just need help on why its slow as takes ages to even go up a slight incline........
