Manual was destroyed and this purchase made it possible to recover my manual . It was easy to down load and smooth to use thanks .

Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.

Bearing Assembly
The Teres bearing was designed to have a lot of viscous damping. This damping helps swamp the effects of stylus drag, resulting in better speed stability. For this reason heavy oil (30 weight) is provided. With heavy oil the bearing will turn smoothly but there will be a lot of resistance. This is by design. Please read this information carefully before assembling your bearing. The Teres bearing has been machined with very close tolerances. The radial clearance in the bearing is only 4 to 5 ten-thousandths. This tight tolerance results in superb stability reducing rocking to microscopic levels. However, with these tolerances it is imperative that the bearing is clean and that proper procedure is used for assembly. The objective is to have the bearing completely full of clean oil, including the recess in the top of the bearing housing. If air becomes trapped in the bearing it will not seat properly. The bearing must be assembled dry to avoid trapping air. The procedure: 1.Using the included 6-32 screw attach the bearing ground wire to the bottom of the brass bearing housing. Pointing the crimp connector toward the center of the bearing will make it easier to install the bearing into the base. 2.Attach the brass bearing housing to the base
using the supplied 1-1/8" nut. Hold the bearing housing tightly in one hand and tighten the bearing nut with a large wrench or pliers. The bearing nut should be snug but not excessively tight. 3. Clean the bearing housing and spindle thoroughly. Wiping down the bearing surfaces with rubbing alcohol on lint free cloth works well. 4. Fill the recess in the bottom of the spindle with oil and press in the ball bearing. This displaces air in the recess and will hold the ball bearing in place. Be sure to completely wipe away any excess oil. 5. Place the brass thrust plate in the bottom of the bearing housing with the white Delrin button facing upward. The thrust plate needs to be held flat as it is lowered into the bearing. A simple method is to attach a small loop of tape to the end of a pencil. Then stick the thrust plate to the pencil and lower it in place. Be sure that the Delrin button is facing up! 6. Carefully pour about 5ml of oil into the bearing housing without getting any oil on the sides of the bearing. A syringe or eyedropper makes this much easier. The oil level should be just slightly below the top edge of the lower journal as shown in the illustration. This is slightly more oil than is
