1st run of the Lesu 374 was not good!

Lesu 374 and my new expandable trailer

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]

Sounds to me the pump is starving for oil , and it’s extremely noisy

[@goranb3062]

Yea definitely and he needs to check the pressure and all. Something is definitely wrong I wouldn’t run it like that

[@TheNZSlayer]

@@goranb3062 yes indeed, will end out blowing the pump, running her dry. The oil flow valve is set to lean. Hence why she is screaming

[@goranb3062]

@@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

[@kaydennewman804]

I love your transport haller/trailer i love the blue

[@TheNZSlayer]

So cool buddy best video iv seen of this trailer. That truck does very well. That trailer is beautiful

[@yellowironcowboyrccon7484]

Thanks, its a very nice trailer for sure.

[@johnnolan8074]

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.

[@koryperry7253]

LOL lots of fun .

[@redundantlol8760]

The tank is just too small for that model, it needs more volume to work properly.

[@wolfgangroll1439]

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.

[@yellowironcowboyrccon7484]

Yes its 6mm

[@slickeydew]

The Zetros are the best rc truck to pull heavy loads,plenty of power and ground clearance

[@saehrfarmsandagrepair]

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 …

[@samdutton1612]

hi i also have a C374L with major hydraulic issues, im on my second lesu valve block, not cool, going to replace it with a csmi valve block and pump

[@yellowironcowboyrccon7484]

I got a premacon in mine

[@goranb3062]

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

[@yellowironcowboyrccon7484]

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.

[@goranb3062]

@@yellowironcowboyrccon7484 yea it definitely and you probably have a some air in the system. How big is that oil tank on the 374.

[@terryperrott8567]

Did you get it to operate like it should? It should just plow through that loose dirt.

[@vbdino]

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?

[@vbdino]

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.

[@yellowironcowboyrccon7484]

I belive that noise is the esc's my other excavator does the same thing.

[@scottharris6423]

Are you going to hook up the ramps with eclectic or hydraulics???

[@yellowironcowboyrccon7484]

At this time im not, ive got two many other things going on. But in the future it would be cool to do that.

[@karlheinzwill7898]

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

[@scottharris6423]

Well it looks great but it's disappointing that it doesn't operate like it should. Hope you can fix it soon.

[@yellowironcowboyrccon7484]

Thanks Scott

[@karlheinzwill7898]

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

[@rym81]

hi.you should reduce the speed of the pump. It does not need to go at full speed. Has set mine at around 50%

[@r.ccustomtruckingsydneyaus4632]

yes about time

[@awesomusmaximus3766]

That pump is running way too fast it can slow down the actuators due to cavitation

[@yellowironcowboyrccon7484]

This vedio is pretty old..the excavator runs real good now

[@r.ccustomtruckingsydneyaus4632]

still has lots of air in the lines mate

[@FREDeierschmalz]

Sehr langweiliges Video 😢

[@malawicarsten]

Hi I have sent you message on facebook regarding spitting oil out of the tank

[@yellowironcowboyrccon7484]

I haven't seen them.
