Traction IH-574 1976 Hydraulic Noise Very Loud

[elsmootho]

IH-574 makes a **** of a moaning/groaning sound when the hydraulic transmission gets engaged or loaded up. It gets a bit better when warmed up but it seems very very loud to me. Almost as loud as the engine maybe louder sometimes. The noise increases in loudness as you load it up more, it seems to be much worst in the low speed range compared to the high speed range.

I'm a mechanic with very little experience with tractors so i'm not sure how loud is too loud, is it me, or do these trannys sound very loud?

Thanks & Best Regards...
