Hello all i have just joined the forum to ask a question regarding the turbo on a wheel loading shovel cat 988h, i have been informed that due to the machine being at an angle whilst picking up some heavy gear (rear end off the ground approx 15-20 ft in the air) that the turbo has been starved of its oil and therefore it has broke and its costing £7000 for a new one, i was just wanting some answers to state wether the machine being in this state would break the turbo ? (if so how long would it have to be in the posistion to sustain the damage to the turbo) and would the turbo blow straight away if it is starved of its oil or would it take a couple of days before it broke? cheers for your help appreciate it

If the oil pan sump is at the rear of the machine then there is good chance that the oil pump was starved of oil with the back end up in the air that far. Did you have any low oil pressure warnings in the cab? Are your warning lights functioning? If you starve the turbo of oil there will be damage to the bushings very shortly after. What kind of symptoms are you having that makes you think the turbo is damaged?

Well....



Ok so based on the hight of 20 feet assuming your talking at the counterweight, your loader was at an angle of 53 degrees. That is a pretty steep angle for a loader to be at. Now your in a little bit of a grey area: would hitting a 53 degree angle toast your turbo right away.. No. Continued operation at that angle could cause it to have lube issues, it would have to use up the oil in the bushings and after that it would spool into pieces. In terms of timeline it could depend of the amount of damage done to the bushing could be a couple on minutes could be hours it is hard to tell, in my experience once a turbo starts to fail it is not long before full failure. Hope this helps

I take it, that, by your comments, you must be a machinery operator, and it sounds like you did something with extremely questionable behaviour.



In your profile, you did not include any personal data, but I would guess that you would be about 18 to 22 years old, and had limited working experience. After all, it would have to be someone young and with a certain lack of knowledge to do what you did. You must have spent too much time on YouTube, watching some of the other people trying to destroy equipment.



Tell me: if you owned that piece of equipment, and you watched someone do those sort of things, just what would you do to the operator?

Hello I also just join the forum to ask a question regarding 988H wheel loader

My machine has a problem The 988h is running good in forward gear and when we shift the gear. Reverse the machine hardly moves and making noise near front propellor shaft. We checked transmission oil both the differential oil front and rear. But the oil is clean.

Somebody please help me to solve this critical problem.
