Check the listing for details. Sioux 645 L Valve & Seat Grider - Complete Set. Condition: Used. Listed at 2000.00 USD. Sioux 645 L Valve & Seat Grider - Complete Set. As you can see in the pictures, this is a 100% complete valve and seat grinding system with all the arbors you would ever need to do engines from very small bore to large diesel trucks. There's also a wide selection of stones including the new stones I just used to do stellite exhaust seats on a Jeep 4.0 (5 angle BTW). there are also several adjustable arbors as well. As you can see the valve seat driver motor is a Black & Decker and I've replaced the brushes and the power cord. It's in perfect operating condition and I've installed the star adapter drive that fits the Sioux Stone holders. Both the 645 L and the seat grinder also come with their own Stone dressers. And, I just recently replaced the diamond cutter points on the dressers. This is probably one of the best setups and most complete you'll ever find. I hate to part with it but I don't have a shop anymore and I'm getting older. So, I want it to go to a home where it's going to be appreciated, well cared for, and used. The weight for both items together is probably 300 to 350 lbs. The auction says local pickup only but I will put it on a pallet if you arrange (and cover the cost) for a freight carrier of your choice to come pick it up. If you have any questions, please just message me.
