Ball Bearing 608VVM

1.) I did all the dis-assembly in my shop.
2.) Since the bearings were pressed on and I didn't have gear pullers I went to a machine shop. In twenty minutes we had the bearings off and the new ones on.
3. It took about 20-30 minutes to re-assemble the saw.
4.) 20 year old saw works as well as the first day I got it

Thanks.

1. Removed the stator cover, as well as motor 'brushes'
2. Used bearing puller to remove old bearing assembly.
3. Tapped new ball bearing assembly in place.
4. Reassembled.

1) Remove Blade
2) Open handle remove & Replace Switch
3) Disassemble gear box and remove final drive
4) Remove & Replace bearings (where we used a puller)

Disassembled saw, removed blade, drive cover (inner and outer)tapped drive shaft from housing with dead blow hammer did not have small enough bearing puller. Used dremel and chisel. removed old grease/cleaned. Heated new pinion shaft bearing on 100 watt lightbulb to 200F and tapped into place. Reassembled drive, greased with EP Moly and reassembled. Saw cuts like new.

1. Remove cover.
2. Drive off the 2 bearing.
3. Drive 2 bearing in.
4. Install all back.
5. Test.
6. Put the tool to work.

replaced with new bearings simply but needed dead blow to remove old and seat new bearings

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.

Completely disassembled the router, used a deep socket to drive out the bearing.
Special care taken to put all the wires back into place and the speed ratio sensor
so that the magnet fit back onto the recess of the sensor
reassembly was completed and the router runs smoothly

Disassembled Hitachi Mv12c router, used bearing puller to removed old bearing, inserted new bearing and rubber gasket. Also replaced carbon brushes as this router was being used in a CNC so was in operation for long periods of time. Reassembled and tested. Runs perfectly!

1-Took blade off, took off screws to remove bearing assy.
2- Pried off both pressed on bearings and used vice to press on new bearings.
3- The process in line 2 is difficult and requires some knowledge in this area. (recommend buying the whole assembly for 73 dollars)
4- Screwed assembly back in.
5- For main spring, unscrewed the two set screws holding main pin and removed pin.
6- Put in new spring and reassembled.
7- Put in new switch to fix auto break function.
8- Put in new brushes which also helped the auto breaking.
