Loader Tc33da hydraulic noise

[Justin259]

I have a 2005 NH Tc33da that has recently started to make a loud whine when raising the loader and bucket curl up. I have checked fluid level and replaced the filter, not to sure where to look from here any help would be great thanks!

Have you owed this tractor for a while? Are you in a cold region?

I have owned it about 5 years now, 700 hours on it now, iv always kept up on filter and fluid changes. Yes I am in a upstate NY but iv ran it year round the whole time iv had it and never ran into this

Double check the shut/off for the hydraulics. On my tc33d, it was on the right side (under your right foot), on a gray block, where all the steel hyd pipes are coming out for the loader. Amongst the pipes, there is a place for a flat heat screwdriver. One way is off, the other way is on.

I did not know about that shut off I will check that first, i am getting a ton of vibration on the line coming from the cooler to the filter housing

You can switch that while it is running too while you try the loader.

I could not find the shut off for the hydraulics, I did notice it is making the same noise when raising the 3point so I ended up taking the loader off to get a better view of the pump area

Here is a picture of the diverter valve (item 2). It should have a valve you can turn with a big flat screwdriver (on/off).

What did you find out on this? Plugged or restricted line (bent, etc)?

 

[Justin259]

I haven’t gotten it fixed yet, took the pump off and apart that all looks good going to start looking for a restriction somewhere

Have you tried a fluid and filter change?
Sounds like a possible flow restriction. Never hurts to replace the filter.

It has been 2 months.
What did you find?
