My experience with the order process, delivery and use of this product could not be better.
The motor came as advertised. Bolted right on . No issues. Contractors Direct delivered quickly. No issues . I would buy from them again
motor replacement bolted right up to existing tile saw. Has already paid for itself. Quick shipping and comparable pricing.
Nice upgrade to a MK270. Slightly stronger motor than original MK270, which is a good thing. And very timely delivery.
Bought this replacement for my 770EXP. Love this saw. Lost everything in Hurricane Ike except for this saw. Tore up everything else but this saw. Motor even ran for a few days till the salt water it was submerged in corroded it. Was amazed how well it held up, still cuts straight and true. Love this saw! Durable and light weight! Only had to replace the motor!
This was a good replacement motor works great and its very quiet compared to my first one.
very capable motor; easy to work on for repairs; design of gear head is inferior, needs a dust filter to protect the interior of the motor for longer life. best motor that m-k has available to date..
Motor arrived quickly after ordering and was a spot on match and fit perfectly. The only thing is that I wish replacement parts were available for the MK motors. My motor that I replaced was only needing the main drive gear and shaft due to the gear loosing some teeth. Otherwise the motor was good.
I purchased this for my MK 270, which is about 20 years old. It fit, and works perfectly. About a third the price of buying the comparable saw new.
Perfect fit. Easy change over.
CUTTING TILES AND GRANITE AND MARBLE MADE IT EASY
Motor works fine on my MK 770 tile saw. Would of gave it a five star rating, if it wasn't made in China!
I wore out my "little" saw by using it so much because of the convenience of it's lighter weight. So when the moter gave out I tried to find replacement parts. No luck! But the price on the replacement isn't too bad considering buying a new one! Just be careful about the replacement screws. After years of usage, they may not want to let go and you can round them out if not careful.
