Says this video is not available when I click to go!!!
If that unit has hydraulic boosted steering clutches check to see that the control valve rods are not hanging up.
i think video should work for you now.
All I hear is the engine running but then my hearing isn't the best.
Well maybe a slight change.
You have a wonderful day. Best wishes. Deas Plant.
Hi, wlf89..
Some thing that just MAY give you a clue is the function of those pedals. The first 3" of travel disengages the steering clutch while the rest of the travel applies the brake. Taking note of where in the pedal travel the noise occurs might give a clue to it. Also, check your transmission fluid level.
Just my 0.02.
Deas is on to something, these are 'boosted' steering clutches, oil is being relieved all the time he pedal is pressed, they all make some noise, maybe you haven't noticed it before.
fluid levels are good, my brother was there yesterday and he said he has never heard the noise either, but i dont know what wouldhave changed for it to just started. if they are "boosted" do they work off the the main hydrualic system or just the transmission fluid? wondering if got air in them or something?
Have you checked the steering clutch/bevel gear fluid levels? also how long since you cleaned the strainer and changed the filter ? Both are under the seat
By boosted, I mean that oil is being constantly relieved so the piston travel is relative to pedal travel, they use oil from the bevel gear compartment, advice about oil level and the screen, already posted, is very useful.
Try checking the adjustment of the steering clutch control linkage. With the roller just touching the valve stem and steering pedals held against the stop bolts adjust the linkage control rod to the longest length that will permit an easy fit of the pins in the pedals.
There is a pressure relief dump valve in the booster control. Maximum oil pressure will occur if a steering clutch will not disengage or pistons in the control valve are sticking.
That's probably the relief valve you are hearing. Pressures are fairly high, 800 psi max, 600 psi relief pressure.
Booster has its own separate circuit, pump, suction screen and filter.
