Hi there and thanks for taking the time to read this. I have a late-eighties/early-ninties woods 650 backhoe on my Kub. B9200.

The issue is with the high pressure side of the pump. There is a large reducer with a fat o-ring. What keeps happening is that this fitting will not stay tight.

Hence the fitting loosens hit fluid blows out and takes the o-ring with it.

On my fittings there is no washer and it seems as it should be.

You can see where the o-ring bulging.

Any help would help !!
