valve seat cutter question

Postby papscub » Wed Jun 12, 2019 9:04 am

I want to touch up the valve seats but don't want to pay the Neway price for a one time only job and don't want to split traactor to take block to machine shop. Looking online i see so many choices (most from India). Anyone that can recommend a brand they've had luck with?

Talk to a local automotive machine shop. You've got the head off. If you pull the valves out, haul the tractor down and have them grind the valves right there. No need to split the tractor. It would be cheaper than buying a decent cutter...

Yes! A small engine place may be able to do them for you as well. It's like a drill with a grinder on the end (way more complicated than that though) to grind valve seats. I did mine with a friends valve grinder. Go to page 25 here viewtopic.php?f=1&t=92172&hilit=valves&start=360

Can new seats be done on the tractor? I just plan to putter around the farm on this, won’t be worked. The valves were absolutely unreal with the carbon and sludge they had on them and it ran good enough drive in a parade. Dummy here let it get hydrolocked and here we are. I’m debating putting it all back together after I lap the new valves in best I can and see how it runs. That’s why I was looking for a cheap valve seat cutter to try and get just a small amount cleaned up.

That carbon and sludge provided a seal - which is no longer there.
