Assembly Instructions - 1hp Extension Dynastraight
Motor Assembly:
Important: Be sure parts are clean and in good repair before assembling. Follow grease, oil and torque specifications.
1. Place Rotor into padded vise with male thread or spline facing upwards.
2. Slip 51927 Rotor Spacer over rotor shaft and down against rotor body face.
3. Press 96441 Coiled Pin into 51922 Front Bearing Plate. Make certain, coiled pin does not protrude beyond internal bearing surface.
4. Place a .002" shim into the base of 51922 Front Bearing Plate as an initial spacing and slide 54520 Bearing to the front plate base. Note: 51951 Shim
Pack contains .001" and .002" shims.
5. Press bearing/bearing plate assembly onto rotor. (For 1,800, 3,400, & 4,500 RPM Models) Slide bearing/bearing plate onto rotor and thread pinion
into place. Torque to 17 N•m (For 6,000 RPM Model.)
6. Check clearance between rotor and front bearing plate by using a .001" feeler gauge. Clarence should be between .001" – .0015". Adjust clarence by
repeating steps 4 and 5 with different shims if necessary.
7. Once proper rotor gap clarence is achieved, install well lubricated 51926 Blades (4) into rotor slots. Dynabrade recommends lubricating blades with
95842 Air Lube. Important: Make certain beveled edge of blade follows rotor outside diameter.
8. Install 51925 Cylinder over rotor and front plate raised boss. Align coiled pin on front to cylinder slot.
9. Press 96441 Coiled Pin into blind hole on 51923 Rear Bearing Plate. Press (2) 96445 Coiled Pins into the back side of rear bearing plate.
10. Peel backing off 51924 Gasket and align it firmly in place onto 51923 Rear Bearing Plate.
11. Place 51923 Rear Bearing Plate over rotor mandrel and insert raised boss on rear bearing plate into cylinder diameter, while inserting short coiled pin
into cylinder slot. Be sure inlet slot on rear bearing plate line up with inlet slot on cylinder. Flip cylinder end to end and repeat step 8 for correct assembly.
12. Press 02057 Bearing onto rotor and onto 51923 Rear Bearing Plate until it is seated. Important: Cylinder must fit snug between bearing plates. If too
tight, rotor will not turn freely. Rotor must be lightly tapped at press fit end until rotor spins freely while still maintaining a snug fit. A loose fit will not
achieve the proper preload on motor bearing. While pressing 02057 Bearing, make certain to contact inner race of bearing only.
13. Add one drop of #243 Loctite
slotted screw head. Torque to 2 N•m (18 lb.-in.).
