Combines Help Rotor pulley on R 7

I know that you don't have to move elevator.I've helped on mine lots of times. Installed a new tourque tube last year and it really wasn't that bad. I think that you must remove bolts that hold sheaves on the innner assemby and remove it in pieces.I'll check and get back to you.John

Honer, The chattering noise you describe may just be the torque sensor spring covers rattling.I have several rigs that have this chatter at certain RPM's.With the machine off,see if you can move the covers,if so,this is probably the chatter you hear with nothing to worry about.You should take a prybar resting it against the concave adjustment and hooking the back side of the rear torque sensor sheave and see if you have any up and down movement of the input shaft to the gearbox.Usually you will see some movement start to develop around 2000-2500hrs. If this is a problem then you will need to disassemble the torque sensor asy..You don't need to remove the clean grain elevator and it isn't that hard to take apart.Require about 30-45mins. once you have done it,but life is alot easier with a service manual.

Thank you to everyone who posted and e-mailed me the help. It is much appreciated. The covers do have some movement, but last harvest when it was making noise, my hired man grabbed the grease gun and greased it about 50 shots while the combine was turning( I just about crapped my pants when I saw him grease while the machine was turning) and the noise went away, so I'm assuming the torque sensor needs some attention.

Hello Honer, Here's how we removed the top rotor pulley.

as does the life insurance policy of your hired man ............
