Product Description ?

Genuine Manufacturer Sourced replacement part used on Hitachi Power Tools. This part is made out of Metal and it 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.

    I had bearing failure on the armature lg bearing & also in the gear spindle. I also replaced two broken pointers, a bad cord, & installed a new cord with clips that had broken.

    Stephen - August 5, 2018
    1) Disassembled the saw & ordered the parts I needed to repair. When replacing bearings it's best to replace all of them due to their age.
    2) I began the repair on the bearings on the armature the small one first. It came right off with the bearing puller I cleaned the tiny shaft & placed the new bearing in the shaft and tapped with the hammer once square pushed it in by using an 8 inch C-Clamp.
    3) The larger bearing on the other end by the fan was really bad but the puller had to be modified so I could get behind the bearing to be able to pull it off. Once off the same procedure was used to install the larger one.
    4) The Armature bearings have been replaced now to reinstall it into the handle portion, cleaned then installed the new bearing, installed the armature then installed the set of new brushes & reinstalled the handle section to the saw.
    5) The gear spindle bearings I thought would be a challenge but the larger recessed bearing came right off easily by pulling the aluminum holder with the bearing once off push the bearing out if the aluminum holder with your fingers.
    6) The smaller bearing on the end by the gear was so close I had to use 2 putty knifes to pry off enough to be able to get 2 larger screw drivers under it to finish prying off.
    7) Once apart clean and reinstall both bearings being mindful to assemble the larger one first into the aluminum holder & making sure it starts square. For squeezing this on I used a deep well socket that fit over the shaft but making sure it was also touching the inner race as not to damage the bearing. I then squeezed it on by using the C-Clamp it will stop in the correct place on the shaft by itself. Now for the smaller bearing in the other end start square then squeeze on but this time you have to use a small washer that fits over the small shaft cause the bearing goes by the end if the shaft by .020 there bearings installed.
    8) Grease and install into saw finish installing blade guards and new blade.
    9) I then installed the new cord with clips and new pointers.
    All parts now installed and the saw is like new again. I have had and use this saw so much I hated to buy a new one because of it' simplicity I am very pleased with the repair as well as ereplacement.com for making the parts available for purchase. Just take your time and pay attention to detail and you will have the same success.
