| Time to take the bar down from the frame. You need to separate the cutter bar at that module so you can clean the debris that is now between the spacer and module. If it has run like that it has also worn the splines on the connecting drive shaft and probably on the pinion in one of the modules. If you catch it in time a new drive shaft should be all you need.
The latest procedure on tightening the tie bolts is to oil the threads with 80-90 oil, torque to fifty pounds and then tighten the nuts another 5 flats instead of 6 flats which is a full turn, I split the difference and go 5 1/2 flats. The oil makes tightening the nuts much easier.
To remove the cutter bar, put a floor jack under each end, remove the four mounting bolts, two each side, and lower the bar. Check the wear on the mounting bolts and bearings on the cutter bar mounts the bolts go through. To much wear will cause the cutter bar to sag forward. What this does is open the gap between the anti wrap rings on the cutter bar drive shaft and the gearbox. This allows material to take out the seal causing a gearbox failure. The other thing that can happen with severly worn mounting bolts and bearings is the yoke attached to the gearbox shaft will not slide fast enough under a load and will push the gearbox output shaft up breaking the gearbox.
Unless someone put shear hubs on the mower it does not have them.
If the material feeds through alright I would not worry about the hood. I would like to know how that happened though. | |
