I was having issues with the unit shutting down High A E temp code 1 on the on board computer screen I tried topping the oils up and coolant but still shutting down after 20 mins on full demand. I had no issues with oil in my lines the only reason I swapped the air oil separator was it was because it is over the 1000 hours since last change and I topped the oil up on a job (hydraulic oil) not the proper grade but will do me for temporary measures as I couldn't get hold of no rotary screw oil. knowing soon as I get back I was planning a 1000 hour service
500 hour is the same service with out the oil air separator.
my 1st feeling was the rads was blocked and thats not cooling the oil 60/40 split on the rear 40% oil cooler 60% engine coolant turns out it was a little dirty but not enough to make her shut down.
back to work tomorrow on the hopes its fixed the issue as I have no means of running the unit up under full load in my yard :( im feeling confident as ive also removed the thermostat (coolant diverter) Its a must that this goes back in but im going to run it for 1 day without to see if its fixed then pop it back in as it is opening in a cup of boiling water but for what it takes to try it without I will risk it for 1 day then if it does shut down after I know what to order :)

You should try to avoid replacing the air filter with the engine on. The dust collected around the filter is sucked in straight into the engine,same for the pump. Also,having dust on the inner filter support is not normal,it should be clean. Maybe the sealing around the filter is not good,filtration material is not good enough,or the filter element is damaged.
@Mobileblaster
@Mobileblaster 2 года назад
Yeah Thanks probs a good idea my method was warm the oil up so it would drain and I was a little impatient so started with the air
@michaelovitch
@michaelovitch 2 года назад
@@Mobileblaster I understand. If the engine sat for the night,don't need to start it to warm up the oil,just drain it. Warm oil is maybe more fluid,but an engine that just worked is full of a nice thick coat of oil that will not be drained, being on the parts everywhere inside. A cold engine has all its oil in the pan,and nothing elsewhere inside.

I've had good service from mine 6 year or so 8 hours aday 5 and 6 days aweek I believe my issues I've had are brought upon by myself ecu failure possibly because it lives outside and its in a little crap spot for water ingress other than this solid air end and good engine. If I was to buy new I would be picking doosan only because of pervious service I've had from past units 👌👍

@Brett Stanley is any oil passing into the air before she shuts down? Dose it start back up and run for 20mins after it shuts down or dose it need to cool down before it will run again I'm trying to find out if eva you clipped the black plastic thing ontop of the air oil separator as its a tricky to line up if that's got broken it will make her shut down also add oil to air. I would check you have the air pipes on the right direction from top hat to pressure valve. It was working fine before the service?

Yep and I always seam to need to do crap like this when it's eva cold or raining. When I had a heated lockup everything ran smoothly 😂 soon as I'm ruffing it in a yard with no shelter heaps of issues haha. It looks a shitter now but when I got it about 5 year ago it had 0.4 hours 4 ish year ago the hour clock stopped working at 2650 I estimate its in the 6k hours now possibly more I give it a service around 3 to 4 months every other service do the oil air separator. I will also service my filter on the breathing line for my helmet around the same time I've got that on order. They should be done 3 to 6 months I do them on the 3 month as I possible be on the top end of the hours used

I honestly cannot take much more bad luck. Anything happens seriously like a fault with the van compressor or blast pot I simply cannot afford to restart.
