Question & Answers

After installing this motor, the blade is misaligned from the groove on the cutting table by about a 1/4". Any idea why? All i did was change out the motor and replaced with old blade. I found out when I tried to do a 45 degree cut and the blade hits the table out of the groove by about a quarter inch

It may be that the inner flange is not fully seated on the blade shaft. Please send a picture to orders@contractorsdirect.com and we will see if we can diagnose the problem.

My motor for my Mk 770 tile saw works although the gears seem to be worn out and slip. Are there replacement parts available?

The complete MK Motor for MK-270, MK-370, 470, 370EXP, 770, 770EXP tile saws must be purchased. Parts for the motor are not available.

i bought this motor back in march and the motor is locked up sounded like the gear inside broke is there a warranty

Thank you for contacting Contractors Direct.
We are sorry to hear about the issue with your motor. Due to the time elapsed, warranty claims must be submitted to manufacturer directly. Please contact MK Diamond at 1-800-421-5830.

I bought this for my son for his mk-770. The original saw is held in place by bolts that attach to the motor itself. There are no bolt holes in this motor. Is there some additional part that is required to fit this motor to the frame.

Greg,

Thank you for contacting Contractors Direct. The bolt holes are located around the blade shaft of this model.

This motor can only fit on MK 770s produced in 2005 or later.

m-k replacement motor for model 770

by - verified purchaser
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..

MK 470 replacement motor

by
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.

Love this saw!

by - verified purchaser
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!

Replacement

by - verified purchaser
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.
