YM2000 brakes

[California]

First guess: That isn't a filler, it's still a brakeshoe anchor pin, but some kind of replacement. Maybe handmade.

Second guess: He has a tractor assembled out of dis-similar parts.

And: ask him to unscrew that 'fill plug' and probe the level of the fluid inside. I would be interested to hear what he encounters.

Does the design of the brake cover in the top picture, (without the adjustor), look familiar to anyone?

 

[kenmac]

looks like a different outside cover but, the same inside part that houses the brake drum. I would be willing to bet that if he removes that outside cover on the one pictured on top that he'll find the same brakes as the one pictured on the bottom.remove those outside covers & then take the picture

The plot thickens ...

Hard to argue with Tom Fredricks.

Toms not big on long emails is he . I wonder what a "wet brake conversion" consists of? I have never heard of such a thing. Does it have the friction discs like a typical wet brake system or is it just the normal shoes floating in oil? I'd sure like to see the inside of one of those. Very interesting.

I guess that goes to show that one (including myself) should never say never. I wonder why tom told me that ym 's didn't have with wet brakes when I bought my tractor ?

I just talked to Tom. He said that he has come across a few YM models with the conversion. It is an add on kit. Not sure if it is a Yanmar or an aftermarket kit. The conversion actually replaced the shoes with discs like a normal wet brake setup & it uses the same oil reservoir as the rear axle. He also made a very good point that, while they seem to work better & last longer than the dry shoes, you will not find replacement parts if the wet brakes ever failed... you would need to convert back to dry brakes.


kenmac,
The YM '02 & YM '20 series tractors all have wet brakes. I'm sure he meant that the '00 series did not come with wet brakes.

As do the YMG models I believe.

 

[HoyeTractor]

Wayne, My books show the YMGs to have the same dry brakes.... or were you saying that the YMGs do also have dry brakes.
