Komatsu PC200LC-6 Hydraulic Oil Cooler Problem

[BDiSab]

I have a 200LC-6 and the Hyd Oil Cooler is leaking everywhere out of the base and the machine is unusable, A quote on a new Cooler is several thousand dollars. I have been told this is a known problem with these machinesm I have found a few websites that sell replacement Oil Coolers, do you think they would be worth a try considering they are cheaper? It doesnt make too much sense to me to replace an expensive part that prematurely fails with the same part again. Any opinions or suggestings welcome.

Thanks,
Ben

Komatsu is uber proud of their parts, I would try an aftermarket unit in a heartbeat.

Our coolers are holding up much better than OEM units.
The majority of our sales on this model are to dealers.
We also offer a 1 year warranty on ours.

I've worked at a Komatsu dealer for about 10years now and haven't heard of a problem with those coolers leaking or blowing out, only that they're not big enough to handle the flow of a high flow attachment and tend to overheat. Komatsu is very good at fixing their problems and won't sell a bad part if there is a common problem with it, that's why they have so many superseded part numbers. If it were me however, I'd go with the aftermarket, if it's cheap enough to buy something else if that doesn't work the first time.
