yanmar ym1500 update

I would replace it now. The longer you run it you risk more damage. The sleeves for the seals are $34 each. I did both seals and the outer bearings. My inner ones looked good because they are open to the fluid. The plate at the bottom needs to be removed completely. Hoye didn't have that gasket so I had to make it. Also look at both drain plugs. Order new ones and the crush washers if they look worn. Check your hydraulic pickup screen also. Now is the time to clean/replace it if necessary. Don't reuse the copper washers for the hydo lines either.

the place i got the pto seal from is just in england and they do sleeves for shafts bearings and seals but i need to get the sizes they do deliver for just £1.50 a order. and its only two days turn around. so will see if any body can come up with the size or i will have to waite till i strip it down i dont know how long its been like that ive just noticed it . thanks

i does definately look like a red rear end,not a green but they do many odd things between countrys. like my YM14 is a 146 but has no hydraulics for the MMM, it is a long lever.

yes im not sure whether its a red back end or green as i think someone said the seal is different. which is not very handy if i order it tin the us and im in the uk as i hoped to get it back on the road asap . ok guys would i notice that the wheel bearing was away and do they just fail i have been using it and never seeen it till the pto seal was replced leaning against the wheel i felt it move forward ? is there any other thing that can be the cause ? thanks

Talk to the guys at Hoye. They will be able to help determine it for sure. But I'm positive it's a red axle setup due to the square housings for the outer bearing and the bolt on brake covers. 30 some years of use will cause the failure. The outer bearings are never greased after assembly so the finally dry out and fail. It has probably been like that for a while. I found mine when it was apart for the hydraulic pickup screen.

ok i will drop them a e mail and see what they say. i can get most parts here except for the sleeves for the shafts? if the sleeve look ok do you think i could get away with out replacing them?

 

[damammel]

If the sleeves look good reuse them. They are probably fine. Might just clean them up if they are rusty.

yep it is a red rear, a green doesnt have the housing extensions on it. the green axles are exposed all the way back to the diff housing.

Thanks Neat. I thought that was the difference by looking at the parts drawings.
