He will start it as soon as all my parts from Hoye come in and he puts it back together
Are we certain that the front (or rear) ring & pinion ratio is the same, between Yanmars with turf tires or ag tires? Or maybe a there's a different ratio inside the transmission depending on tires?When new, the Yanmar YM165d came standard with ag tread. The turf tire option was about a thousand dollar adder. You can't swap between turf and ag tires withot also swapping the wheels.
Not me. I only use 4wd for short distances as necessary.Scotty I thought it was you who posted long ago that their little Yanmar stays in 4wd continually because it is operated only on loose ground. No, somebody else?
My YM186D 4wd shifter is real stiff, apparently from seldom being shifted. An urban landscape contractor was the first owner so the tractor must have seen a lot of pavement in its first 30 years, as well as being operated by inexperienced labor. No evidence of damage.
I only shift to 2wd if I get out on the unpaved lane, to exercise the shifter and keep it usable. The orchard here is all disced, rough to drive on, so I assume the ground is loose enough to slip and avoid damage.
Musta been someotherbody.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.
124060-21600 YANMAR 124060-21600 Gear, Ring Z=105Anyone 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?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.
