That is done alot around here. I was in service repair for 30 years and never done that. If I didn't have service info I needed and would guess , if I was wrong the part came back off. Not around here you pay for the part. I feel if you don't have the service info or schooling don't work on it. They don't even give you the old parts, you have to ask for them.

When I first came down to Mo. my car had a miss. Took it to a place to get some troubleshooting done and I ask if they had the machine to do it. The owner said the newcar dealer don't even use them. Should of stopped right there, but didn't because at the time I didn't even know there was a dealer in town. Well they put a new coil pack on and new plug wires, car ran good. Made them give me the old parts went home checked the coil pack and it was good. Used it later on another car. I went back and talked to the owner and told him, and I didn't like paying for his people schooling.

Exactly, why should I have to pay for replacement of a part that wasn't faulty, or the time of a mechanic who doesn't know what he is doing.

I just ran across this post and I was wondering what the outcome was. And diesel fuel is an approved flushing oil by Komatsu - I keep a 55 gallon drum of diesel/hyd oil mix for flushing my systems when doing hydraulic repairs. ANY time a pump or motor is replaced, the entire system should be flushed and new fluid installed for start up. I use a filtration cart to restore my used oils to <5 micron cleanliness and force the flushing oils through the systems

My M120 had the same problem with a weak hydraulic pump. I was pissed that the dealer did not bother to flush the system and they left a rag in the system that caused the accessory circuit to fail. I flushed the system after bringing it home and finishing the repairs. The old pump lost power especially when the oil was hot. Revving the engine helped but it got so bad that nothing but replacement could fix it.

Check your filters for metal shavings - a key indicator of a pump on its way out.
