I'm guessing this is going to be expensive!!!
The "7T Spiral Bevel Pinion Shaft" broke on my L2850... This is the shaft that connects to "Propeller Shaft" (I'd call it the front drive shaft..). I'm not sure if that is the only problem. I've only removed the propeller shaft so far.
Questions...
Will I have to remove the whole front axle case to get at this part?
How complicated is this job? Will an average home tractor owner (reasonably mechanically minded) be able to handle it?
What will it cost to have a shop do this?
Looks like the cause was some of the bolts holding assembly up came loose and let things drop... Lesson learned is that you need to get under the tractor and check bolt tightness frequently!
I'll attach the drawing from the parts list... Like I said, I don't have it all apart yet, so, I'm not sure if any of the other parts are damaged. At any rate, it looks like the part I'm interested (160 in the pic) seems to come in an "assembly" (read: "more money")... The parts list is below...
Oh well, #$@#$#$ happens!
Just looked up the part on Tractorsmart... OUCH!!!
