Spider and coupling shattered over time (16 yrs.)

John from Columbia City, Indiana

Total Repair Time:

Socket set, Wrench set

The thing that really helped was building an carriage cradle to hold the motor and another one for the drum & housing, to keep them positioned in the correct plane. And that facilitated the removal of the bolts holding them all together without them crashing apart as the bolts came loose.

This technique was especially helpfu l when reinstalling the unit after the repair was done to install the now repaired shaft coupler and spider.

Loosened the 4 motor mounting bolts with a socket set. Removed both couplers with allen keys. Replaced sanding drum side with the new coupler and then motor side. Fit spider in the sanding drum side coupler and remounted motor back into place matching both couplers to each other. Closed any gaps between couplers and tightened with allen k eys. Good as new!

Spider coupling tore

The parts were used on a Supermax 16-32. There are four bolts on the drum side to the frame that will need to be removed. The couplings have two alan set screw\'s that will need to be removed. The couplings slide off easy / some have said they had to use a puller (I did not). The replacement of these parts also solved the clicking noise t hat I had since the first day of getting my \"NEW\" Supermax 16-32. I would not recommend replacing the spider without the couplings (2). Careful examination will show that they have damage and cause the new spider coupling to go bad. Total time was less than 15 minutes.

Spider cushion (coupler between motor and drum) was worn out and vibrating badly.

Darrell from DUBUQUE, Iowa

Tools:

Parts Used:

1. Remove the extension table.
2. Remove the drive belt and the motor assembly.
3. Remove the entire drum head and the motor assembly from the stand.
4. Break the drum assembly and the motor apart.
5. Insert the new spider cushion, the motor, and the drum assembly back together.
6. Replace the drive belt asse mbly and the extension table.
7. Reset the parallel position of the drum relative to the table.

Not any really hard steps, just a lot of them. They also have to be done in this order. You can\'t get the drive belt off until you remove the extension table, and you can\'t get the motor and drum sander off until you remove the drive belt. There is not a way I know to get the spider in without separating the motor from the drum.

Unbolt motor from drum,put in new spider, attach motor to drum. VERY IMPORTANT, must have good grip / support on motor. I thought bolt was still in motor housing, I sneezed,dropped motor on floor, and jammed shaft. Now have to have motor rebuilt or replaced. $500.00 accident.
