I have had my Massey GC2310 for three years and have 788 hours on the tractor. It was three months out of warranty. All services have been completed in a timely manner since it was purchased. The tractor was sitting idling the other day and I went to raise the backhoe. I heard a click and a faint whirr?? and lost all hydraulics. After consulting the dealer I decided to see what was wrong myself. When I pulled the pump out I found that all of the splines were worn off on the first half inch of the shaft. Upon further investigation I found the following problems:
1. The pump shaft only went into the 1 1/2" deep gear 1/2".
2. The front 1/2'" of the gear was worn like the shaft.
3. The raised area on the pump which should have snugly into the machined port on the transmission housing wasundersized by 1/4".
A. These two surfaces are used to correctly align the pump shaft to the gears.
4. The pump was installed with a bunch of liquid gasket material to try to fill the void left by the underszed raise area of the pump.
I took the tractor and pump to the dealer. The factory was notified and so far has offered to replace the arts fo free. Since this is a labor intensive job, that's some help but not alot.
Has anyone else had this failure?
As soon as I get the old pump number I will post it so you can check that this pump is not installed in your tractor.
More when I get more.
