Drive shaft pin
I have a 127 hydrostatic. Early this fall I bought a new coupler and a used driveshaft that I made sure a new roll pin fit tightly. I'm positive that I haven't put ten hours on the replacement parts.
Tonight the roll pin just fell out while plowing snow. Luckily I found the pin and managed to drive it back in. I was going to wrap a hose clamp around the coupler to make sure it stayed together but didn't have one to fit. Ran it about ten minutes and it did it again leaving me sit in the middle of the road as I turned around.
I am at a loss as to why this is happening because I had to use a hammer and drift to drive the pin back in. The new coupler is made of steel instead of aluminum like the old one and I am thinking about putting a tack weld on the pin and coupler to keep it all together.
Does anyone have any advise on this recurring problem???
