Stuck yanmar 165D

[California]

Not me. I only use 4wd for short distances as necessary.
A stiff 4wd shifter when trying to shift OUT of 4wd almost always means that there is "wind up" somewhere in the 4wd mechanism because the tires couldn't slip. An easy diagnosis is to use the loader to lift the front wheels. If it suddenly is easy to shift out of 4wd, it was because there was windup and now the tires can suddenly unwind. Often only a fraction of an inch. ..hopefully the torsional windup is only in the front driveshaft, not the tranny.
Probably the dirt let them slip just enough.

Musta been someotherbody.

I'm familiar with windup, driveline tension, after owning a couple of old 50's Willys Wagons and then 70's Wagoneers. The way to unwind them, was to back up in a zig zag pattern while pulling lightly on the 4x4 shifter. That also works for the Yanmar.

But this one's shifter is stiff even after lifting the front with the loader. I've seen posts about breaking the internal parts of the 4x4 shifter and think about that every time I have to shift it.

Anyone know where a flywheel ring gear for this 165D would be?

Might be bent shifter. Do some experiments,,,is it is also hard to put into 4wd?

BTW, our old Willys had a small block Chevy & OD. Girlfriend is driver. My horse Dewey is in the trailer - Dewey was a huge 16 hand Appy who was always willing to squeeze into that tiny trailer & go for a ride. Wish I still had them all.

Does anyone know the differences in liner specs of 2TR13A vs 2TR15A other than 75mm vs 80mm bore? Are they both dimensionally the same otherwise?

I know the part numbers, I'm just curious if a 15 sleeve will fit in a 13? If they are dimensionally the same other than 75 vs 80 mm bore? I wonder how a square block (2.9" bore with 2.9" stroke) 2TR13A would work with the bigger piston making it oversquare. However, I would prefer an undersquare (torque)
