Yes, it is a common thing to replace those rubber bushings on the shoe. But I can't believe that he paied $8000 just for this. If you find a way to press the old ones out and the new ones in, it is fairly is to do yourself.
Pull type, Something is wrong there. You can buy every bushing on the shoe for less than $400.00. I've replaced them in my shop and I don't have a very big press. K.A.
We had local alberta combine mechanic replace them for $500 cdn and he came to the farm and did it.Was the bill he showed you just for bushing. It gets expensive if they let them hammer away to long. Neighbour broke both chaffers and the supporting hardware with cast update brace they were still under 4000.
