Product Description

?

This Ball Bearing has metal shielding on both sides. This is a genuine Dewalt replacement part that is sold individually. • Ball bearings are used to reduce friction between rotating parts. The balls or rollers take the load and spin, distributing the weight evenly while the minimal contact area of the ball reduces friction. This reduces wear on the tool and allows it to run smoothly. • Bearings experience constant wear when the tool is in operation from pressure, heat, vibration and friction. Because of this, many Bearings need periodic maintenance or replacement.

Total Repair Time:
15 - 30 mins
Tools:
Socket set
Parts Used:
605040-20, 605256-01, 176638-00
Removed front housing,
Used snap ring pliers to remove snap ring,
Used different sized sockets on bench vise to remove broken spindle and front housing bearing.
By using sockets to straddle spindle and slowly tightening vise it works like a manual press and spindle pushes out easily.
Bearing and spindle can then b e installed using same idea.

Magnet Ring broke in pieces!!

Hugo from Miami, Florida

4 of 4 people found this instruction helpful.
Difficulty Level:
A Bit Difficult
Total Repair Time:
30 - 60 mins
Tools:
Screw drivers
Parts Used:
N618274, 605040-20
1. Removed the End Cap.
2. Carefully searched for pieces of the broken Magnet Ring.
3. I used the Gear/Ball Bearing Puller to removed the Ball Bearing (Is supposed that the Puller help to remove the Ball Bearing without damage it, but that wasn\'t my case, luckily I bought also a replacement of the ball bearing).
4. I fo und the inner piece/ring of the magnet ring still mounted, so, I used a flat head screw driver to remove it, this helped me to see what is the right side to put in place the new one.
5. To put in place the new ball bearing I have used a hammer and a socket with the same size of the inner race of the bearing.
6. Then placed again the End Cap.

Blade wobble

Ed from Edmonds, Washington

A Bit Difficult
Total Repair Time:
More than 2 hours
Tools:
Screw drivers, Socket set
1. Typed in blade wobble for a DW706 miter saw in U-Tube and found a video that showed me everything to do. Everything in on U-Tube.
2. Replaced the two main bearings and the two needle baring assemblies.
3. Replaced the spindle gear, but probably didn\'t need to.
4. Put saw back together and still had blade wobble. Too k off the blade and noticed the washer that fits inside the blade was worn pretty badly. Ordered a replacement, which cost about $3.50 and put the new washer on and all is well:)

The original bearing was causing vibrations and seizing-up the reciprocating blade.

R. from York, Pennsylvania

2 of 2 people found this instruction helpful.
Difficulty Level:
A Bit Difficult
Total Repair Time:
30 - 60 mins
Tools:
Pliers, Screw drivers, Socket set
Parts Used:

Since the original bearing flew apart after I disassembled the motor housing and tested its operation. I cut off the remaining bearing race with my Dremel tool using the cut off disk. I then installed the new bearing using a long socket with a connection size slightly larger than the diameter of the shaft for the bearing. I ensured that t he surface of the bearing being driven against was kept flat with a heavy, thick washer so the force did not cause the bearing to come apart. I then used my 5-pound sledgehammer and two pieces of scrap 2 x 4s to protect both ends of the shaft and the long socket.
I used this method since I neither have a small gear/bearing puller nor a press.
