Farmall 1466 Posted October 23, 2022 Share Posted October 23, 2022 Got some issues with our 1466 that came up a couple of days ago. Clutch is really, really light (overboosting I feel) and engages abrupt, you dont have any control over that with the pedal. And at the same time, steering became dodgy. When driving, it is alright but when standing still, turning the wheel doesnt always make the tires rotate left or right. It takes a couple of rotations from the wheel, like it is building pressure or so. Before doing anything, I wanted to confirm my suspicions on mcv problems. Is the pump tired? Thanks!

snoshoe Posted October 23, 2022 Share Posted October 23, 2022 Clutch sounds like sprag is slipping and dump valve is closing late. Steering could be anything from pump to seals in cylinder. Whole thing could be plugged hydraulic filter. Quote Link to comment Share on other sites More sharing options...
Farmall 1466 Posted October 23, 2022 Author Share Posted October 23, 2022 Filter is clean. I think I'll check MCV pressures. What should they be? Dont have a manual at hand. Quote Link to comment Share on other sites More sharing options...

Don't have a manual either. Here is what I would expect. Steering- 1900-2100. Regulated-200-300. Lube-15-30. Quote Link to comment Share on other sites More sharing options...

Plug below relief valve will give you regulated pressure. Plug at back of mcv that takes a 5/8" wrench will give you steering or the Plug right above it or the Plug at the other end of that bore. Which is flow divider spool bore. Quote Link to comment Share on other sites More sharing options...

While you've got it apart, if it was mine, I'd replace the springs in the MCV, too. They sell all of the springs in a kit, the part number is 830458. It's about $50.

Farmall 1466 Posted November 27, 2022 Author Share Posted November 27, 2022 We had a relative of ours rebuilt the mcv and pump and the pressures are good now. We however still have some issues. Clutch is still funny and steering isn't completely solved either. Is there a possibility that the clutch booster is leaking internally or can this not cause the problems?
