Belt Replacement 4. Lift forward idler pulley (item C) by hand and remove cotter pin (item E) to disconnect the link rod from the bellcrank. 5. Remove reverse v-belt from engine pulley, and then work it out around reverse idler (item D) and over link rod. 6. Work reverse v-belt out around forward idler (item C), over link rod, and off tiller. 7. Install new inner belt in reverse order of its removal. 8. Reinstall both link rods in bellcranks and reinstall cotter pins (items E and F). Be sure rods are in forward bellcrank holes and cotter pin legs are spread. 9. Install forward v-belt. Check to be sure belts are seated in all pulleys. 10. Check belt stop and clutch adjustments according to Adjustment Section instructions. 11. Reinstall belt guard. 14 Adjustments CONTENT OF SECTION This section contains adjustment procedures for the rotary tiller. These adjustments are made during assembly and thereafter are normally performed only to correct specific problems. Follow all instructions in the order given. À WARNING To avoid serious injury, perform adjustments on tiller only when the engine is stopped. Always remove spark plug or remove spark plug wire and insert terminal in V-notch on cylinder ccver. See figure 14. Figure 14. Inserting Terminal In V-Notch ADJUSTMENT PROCEDURES For access to some adjustment points, the belt guard (figure 15) must be removed. To remove the belt guard, remove the two screws (one on each 15 side) and loosen (from inside) nut on the washer headed capscrews. BELT STOPS The purpose of the belt stops is to disengage the belts when the clutch lever is released. Incorrectly adjusted belt stops may prevent the drive from disengaging. To adjust the belt stops, remove the belt guard and proceed as follows. For the model 1003 tiller, the belt stops are correctly adjusted when there is a 1/8 inch (3 mm) clearance between belt stop and engaged (tight) v-belt. To check, press the idler pulley tight against the belt and measure the belt stop clearance (see figure 16). If clearance is not 1/8 inch (3 mm), loosen capscrew and adjust belt stop. Tighten cap-screw while holding belt stop in position. Recheck and readjust as necessary, and then reinstall belt guard. Figure 16. Model 1003 Belt Stops the model 1005 tiller, proceed as follows: 1. Push both idler pulleys together with one hand to seat belts (see figure 17). 2. Measure gap between belt stops and forward and reverse belts (see figure 17). The clearance should be 1/8 inch (3 mm). If not, loosen capscrew, adjust belt stop for proper clearance, and retighten capscrew while holding belt stop from moving. Repeat check and adjustment as necessary, and be sure to check both belt stops. fmEmnhtsSiu Adjustments When a clutch lever is squeezed to engage the clutch, an idler pulley (items A and B, figure 18) moves against and tightens the related belt. Power should then be transferred from the engine pulley to the driven pulley without belt slippage. If a clutch is not disengaging properly or if belt slippage occurs, adjust the clutch as follows: 1. Loosen setscrew (item C, figure 18). 2. Slide wire clamp (item D) up clutch rod (item E) to increase belt tension or down rod to decrease belt tension. 3. Retighten setscrew. 4. Check, and, if necessary, repeat adjustment until clutch operation is satisfactory. BELT TENSION Normally, belt tension can be adjusted by increasing clutch tension (moving wire clamp further up control rod). After some use, however, belts may stretch so that this adjustment cannot be made. If this occurs, loosen the four engine mounting nuts (see figure 19). Slide out one or two of the slotted shims which are stored under the mounting nuts, and insert the shims between the engine and frame as shown in figure 19. Retighten engine mounting nuts and readjust the clutch as necessary. PULLEY ALIGNMENT For model 1003 tillers, the engine drive pulley is properly aligned when it is 0.688 inch, or 11/16 inch (17.4 mm), from the end of engine shaft (see figure 20). If not, loosen engine pulley setscrew and adjust as required. Be sure to retighten setscrew. Then visually check the alignment of all three pulleys. If the worm gear drive pulley is not aligned with the engine pulley, loosen the setscrew and move pulley as required. Retighten setscrew. J.6 Adjustments For model 1005 tillers, the reverse pulley (item B, figure 21) should be positioned so there is a gap of 0.20 inch, or 13/64 inch (5.2 mm), between pulley face and shaft seal. A distance of 1-1/2 inches (38 mm) from center to center of the two drive pulleys is then correct. Loosen engine pulley setscrews and adjust as required. Be sure setscrews are retightened securely. Visually check alignment of pulleys (items A, B and D). If pulleys are not aligned properly, loosen setscrew in worm gear drive pulley (item D) and move........ forward or backward as required. Retighten setscrew securely. fwimaiiriiu Assembly CONTENT OF SECTION The ...
