Check if a servo remains slightly open, I had the same problem on the kabolite the valves did not return oil to the tank because a servo remained slightly open
@@TheNZSlayer yea this issue should have been resolved on the Work bench. Way before you start digging with it. While it’s a part. Now it’s more pain in the ass to Get it a part
Check with the shipper on your parts. I ordered a brand new axle for my dump truck in September. Ask them to check it and they sent me another 1 and it arrived within a week and a half.
Hello my model building friend. Something is wrong with your CAT 374 excavator. I would let's say the pump runs around in a twisted manner. And the lines twisted closed. And so can not build up any pressure . You can hear that too. Greetings Kalle from Germany
Hello and what else I wanted to say! With your swing drive (rotating excavator superstructure) there makes the gear also noises. Something was probably not put together correctly. Greetings Kalle from Germany
Great Video 👍 I know it sucks when it doesn’t work as it should. But from the get go it didn’t sound good. What pump are you using from Premacon I got a 1200ml pump and their 6 v2 valve block and I hope you got their pressure regulator valve sometimes they can cause problems. I think you definitely got some air in the system and sounded like it was starving for oil. And check your pressure gauge where it’s at
Its the 1200 ML. I have the premacon pressure relief valve but wont install it till i get the servos for there valve block. The lesu is still in it now. Your the second guy that said it sounds like its starving for oil.
I like how the certain amount of people on here are saying they know what’s wrong and Say they would do this and that and wouldn’t do this and that but yet they really don’t know shit, hahaha f’n people …
You must be glad to finally play with your excavator! Looking forward to see how well the powder coated track will hold. I hear a strident noise when you move the tracks, what is it?
Well at 11 minutes, I see it is not much fun playing. The line between the between the pump and valve may have restriction or the pump assembly has too much scealant in it creating flow restriction. You could verify it by installing the pump pressure gauge on one valve exit and see what pressure you get with valve fully open.
Hey, did you use the 6mm Hose for the Tank to pump input connection. I had exactly the same issue with the Lesu pump and going from 4mm to 6mm Hose in the input fixed it.
