How do I remove the back beater and gearbox on a 1030 knight manure spreader?

check the fuse next to battery --and check all the safety switches and connections

Ask them, they made it.

I too have been going crazy trying to find instructions for this seed spreader. Go to Ortho Products online and select chat. Tell the agent the UPC code for it, which is: 71549-08450. They can then email you the one-page instruction sheet for it. Otherwise try this site where I uploaded it: http://pdfcast.org/pdf/whirlybird-spreader

....As Ray Sabourin said, the front beater bar drive is a problem area. On my Windtunnel Dual V, the front gear overheated and upon cooling, the melted plastic on the gear fused to the gearbox housing! It was a pain to remove the gearbox, but once it was removed, I managed to separate the fused gear, turn down the damage on the gear in a lathe and machined out the damage on the case with a vertical mill. I then lubed everything with machine oil and put it all back together. It fixed it and saved about $75.00 because the gearbox is not available without also buying the electric motor that drives it. -A Difficult fix that could not be done without high mechanical skills. :-)

There is no way to repair a worn gear, this is due to the heat treating of the metal to toughen it against wear and tear of use, otherwise it wouldn't last but a few hours of operation, this precise heat treating of the steel can only be done with special equipment and requires special skills to pull off correctly, so no you will need to get new gears. I know from personnel experience that you can get parts for these old farm implements, call around and see what you can find out. I will say that worn gears are not the common reason for hard gear engagement, that would be worn shift dogs and synchro ring cones or worn gear shaft bearings.

Check and make syre you have not sheard the pin on the chain sprocket, and the that the chain is still on.

back yard fix
use the right size nail
use the right size split pin
use the right size bolt

An axle or “beater bar” is located inside the bin next to an open slot in the floor. Attached to the axle is a series of beater arms or paddles. When the axle turns, the paddles break up the material and direct it toward the opening where it is deposited evenly on the soil.

If this is one of the later-model Sunbeams, the housing has an upper half and a lower half. By removing the upper half, you can see the motor and the gear train. You will have to take out one of the beater gear posts and reinsert it to align properly. I suggest you look at both gear posts and check for worn or broken teeth. In which case, you will need to replace the bad part[s].

Older model Sunbeams have a gearbox housing that mounts onto the front of the motor housing. When you remove the gearbox housing, you will see the gear posts inside. Check for worn or broken teeth and replace as necessary. To insure proper alignment when reattaching the gearbox housing, align the two gears relative to each other then push the gearbox housing back onto the motor housing. The motor spindle will slightly turn both gearposts simutaneously during this process but will keep the proper alignment. You may have to repeat this process a number of times until you get it right.
