Post your questions or problems you are haviing with your Yanmar tractor here.
I have a mid 80's Yanmar 336d. Wonderful machine until an issue yesterday. I was moving dirt and everything was working fantastic. I took a lunch break and when I returned to the machine, started it up, put the powershift in 1st gear, let out the clutch and got a grinding noise in the range shift area. It doesn't appear to matter which gear I'm in, even neutral, on the range shift or the power shift? WHen I let out the clutch, I get the grinding noise, like when you shift into gear on a truck or older manual vehicle, and do not quite have the clutch completely depressed. The part which really confused me, is if the power shift and range shift are both in neutral, why would it grind when I release the clutch. I've changed all the filters, oil and cleaned the screen about 30 hours ago. I had no indication prior to stopping for lunch? No clutch slippage, gears all worked properly. Any suggestions to troubleshoot would be GRATEFULLY appreciated. Thank You in advance!
The splines sometimes shear. Try listening with a mechanics stethescope or large screwdriver right in front of the transmission housing or at the rear of the bell housing. That is where the coupling is located.

Is there any other location to find yanmar parts?
Yes, but I don't think it would be fair to list them here. You can google although you will find this is the best sight for parts.
Thanks, I wasn't trying to offend Hoye....They are fantastic to work with and I've enjoyed doing business with them over the years. I've been buying parts from them for over 10 years. I was just wondering if that coupler may be available somewhere else since Hoye has it on backorder. I'm just on a time constraint and need to get this tractor up and running. I hate to tear it down if I can't get the part?
For what it is worth I think the part number is 194110-25220 https://www.southernfarmequipmentimport ... or-splined
