I’ve bought a heap of aftermarket parts for my Samsung from numerous suppliers in Korea because you can’t get them from any dealer or wrecker here in Aus. Funnily they all came bagged up labeled as Volvo and IMO were very fairly priced. They are: Hyco, Partsbank, Topglobalparts and Heavypartsolution. You need part numbers though otherwise it’s fruitless. Postage was surprisingly quick.
Please make sure you flush the case drain down to the travel motors, it's common oil to all 3 motors , IF there was a mechanical failure. If not, just spin a filter on and be happy. BTW, why did you have to replace it?
It was working fine, but was leaking oil out of everywhere. Plus leaking into swing gearbox. Pushing oil up the dipstick tube. slowly getting worse. 7,000 hrs on it. I called 3 local places, Volvo, Komatsu and one hyd shop, to have a seal kit put in. All three said just get a remanufactured one.
I guess parts plus labor gets close to the same $$$ amyways.
No, in the pump room there should be a large spin on filter mounted relatively high up. Should be gold colored 6-8 inches in diameter. That's your case drain filter. It should be serviced at least every 2k hours.
Not everyone uses a case drain filter. Stops a lot of bad catastrophes from spilling over, plus, it gives you a quick look at the health of your hydro system.
BTW high case drain restriction (plugged filter) can cause external leaks and shaft seal leaks. Also tank return filter can cause raised back pressure.
10-4, I have replaced it not to long ago. 1,000-1500hrs ago. I will definitely replace it now and check the insides.
It started seeping out of the sides when parked for the winter, cold building. it would kind of dry up when using it. Same story with all the big hyd cylinders. I have redone them all in the last 2 years. I imagine the orings are just old and hard.
