Wheels for a Yanmar 147D

[California]

There is a shoulder around the spring side to center the wheel on the hub, so I think Yanmar always mounted the hubs springs-out. On the other side the only thing to center the wheel is the lug bolts.

On the YM186D I don't have a ROPS because I need to go under the orchard trees. So I want maximum width for safety on sloping ground.

I put the hubs on the belt sander to verify that the flat side was truly flat. I found they were already machined flat. Then I mounted the hubs springs-in. One problem with mounting the hubs springs-in, is its difficult to tighten the clamp bolts. Also, I have iron weights outside the wheels and would like to mount a second set inside the wheels but that would make the clamp bolts completely inaccessible.

Here's a photo I posted in an old thread about the hubs.

Added: And for anyone wondering WTH we are talking about, I found a photo that includes the hub installed, with the clamp side inward. Here you can see the ring machined on that face of the hub. Its the same diameter as the center hole of a wheel. (I also tied the PS hoses higher up into the loader chassis after discovering they were hanging like this).

Thats how mine were installed (apparently since new by the dealership) because the paint is in super condition showing NO signs it was ever the "correct" way. I'm now wondering if that same dealership was the one responsible for installing the 3 point hitch wrong as well. Thanks for the pics & explanation california.

I figured out the "slop" issue today......SNIP>>>>>. I noticed one missing & the other scabbed together with a long bolt & a bunch of washers (same hack mechanic im sure). My local yanmar dealer tells me to order them in will be $27 each. INSANITY!! Any suggestions where i can get these small little items at a REASONABLE cost?

For buying any and all industrial hardware and metals, there is a source for good prices even on one at a time quantity from McMaster-Carr online.
Everyone who designs machinery keeps one of their catalogues around as a reference book.
McMaster has been around forever and is where most of the small fab and machine shops buy their material and fittings.

That will get you to the online version of their catalogue. Then enter setscrew, chose metric, chose 8mm, and you'll find about 12 different kinds available.
