- Page 7 LIFTING BOLT HOLES Most NACD products have provisions for at taching lifting bolts. The holes provided are always of adequate size and number to safely lift the NACD product. These lifting points must not be used to lift the complete power unit. Lifting excessive loads at these points could cause failure at the lift point (or points) and result in damage or personal in jury.

Adjust clutch to compensate for wear. 1-3. Clutch driving plates are oil Replace the plates if slippage continues. soaked. - Page 10 7. Straighten the bent portion of the hub nut lock washer (27) from the hub nut (26). Remove the hub nut and lock washer from the clutch shaft. Discard the hub nut lock washer. 8. Fit a loose, steel, protective cap so it makes direct solid contact on the pilot bearing end of the clutch shaft (8).

15. Remove the flexible hose assembly (32) from the split collar (127). Remove the 90 degree fitting (150) and the fitting (149) from the flexible hose (32). Remove the grease fitting (5) from the fitting (150). 16. Remove the hex-head capscrew (12) and lock washer (13) and lock (11) that secure the bearing re tainer (10) against the clutch housing (1).Remove the bearing retainer (10) from the clutch housing. - Page 12 1. Using solvent or steam cleaning, clean all parts. Parts cleaned with solvent or steam cleaned must be dried and oiled immediately. 2. Examine all parts carefully for grit, dirt and abrasives and reclean them if necessary. Cleaning Bearings Do not remove grease in which new bearings are packed. Thoroughly wash bearings that have been in service, in clean solvent.

Page 16: Prior To Installation
(6). PRIOR TO INSTALLATION Most NACD products mount directly onto the flywheel of the engine. Flywheel to driven component interference is possible due to mismatch of components or other reasons. Therefore, engine crankshaft endplay as well as flywheel alignment check must be made before the driven component is installed. - Page 17 Alignment -(Also reference SAE J-1033) 1. Bolt a thousandths increment dial indicator or gauge to the engine flywheel so that the indicator is perpendicular to the face of the engine flywheel housing, and the indicator stem is riding on the face of the flange. See Figure 2 2.
- Page 18 Figure 4: Checking Driving Ring Surface Figure 5: Checking Pilot Bearing Bore of of Engine Flywheel Engine Flywheel 6. With the indicator mounted as in the paragraph above, adjust the indicator stem so that it will ride on the driving ring bore of the engine flywheel. See Figure 6. Rotate the flywheel. The driving ring bore eccentricity of the engine flywheel should not exceed 0.005 inch maximum total indicator reading.
- Page 19 1. Excessive loads tend to deflect parts to which power take-offs are mounted. To determine deflection under actual operating conditions, a dial indicator may be mounted on a rigid part of the engine, such as the crankcase. or independently on the foundation . Readings taken before the drive is installed, with the engine standing still and when under actual operating conditions, will indicate the extent of such deflection.
- Page 20 (Most PTOs have serrations on both ends of the cross shaft.) All NACD handles are cast with this hex.
- Page 21 NOTE: Do not add grease until the tapered roller bearings are adjusted. The only approved method for adjusting tapered roller bearings in NACD power take-offs is as follows: 1. Tighten the adjusting nut (see Figure 8) and rotate the shaft to align and seat bearing rollers.
- Page 22 4. Check the endplay as follows: a. Mount a dial indicator with the stem resting on the end of the shaft. Mark a spot adjacent to the in dicator stem. b. Use a hoist and fish scale to raise the shaft with 200 lbs. force. c.
- Page 23 To determine side load deflection attach a dial in dicator to a rigid part of the engine. The indicator stem or plunger should rest upon the PTO housing at the bearing. If the direction of the load is known, the in dicator reading should be taken directly opposite the known load direction.
- Page 24 Figure 10: Checking Deflection with Direction of Load Unknown. The sealed-for-life pilot bearing should not be lubricated during service, damage to engine crankshaft could result from trapped grease pressure. Clutch shaft, normally, will not be drilled. If drilled, a plug should be installed to prevent inadvertent greasing. Lubricant Use any high grade, high temperature, lithium base NLGI # 2 lubricant with an EP additive for anti-friction bearings, having operating temperatures of 200 degrees F.

- Page 27 Figure 13: Aligning Engine and Gear Head. ASSEMBLY INSTRUCTIONS FOR PILOT ROLLER BEARINGS NACD has available roller type pilot bearings in several sizes for use with PTO’s. Many specifications have been written to include this type bearing. All of the roller pilot bearings available are the separate race type i.e.
- Page 28 INSTRUCTIONS FOR ASSEMBLY 1. Press inner race of roller bearing on clutch shaft flush with end of shaft 2. Place unit on bench with clutch shaft vertical as shown 3. Measure dimension A as shown in figure 1 4. Installation dimension B for bearing outer race is determined by subtracting the bearing width shown in figure 3 from dimension A (B=A- Brg.
- Page 29 THROWOUT COLLAR ASSEMBLY Sealed For Life Type Bearing During disassembly, remove the external snap ring (5), and with a bearing puller remove the collar (4) and bearing (3) from the sleeve (1). Remove the internal snap ring (2), and remove the ball bearing (3) from the collar (4).
