9 MAINTENANCE ALWAYS ENSURE THAT THE HYDRAULIC MOTOR IS PRIMED WITH HYDRAULIC FLUID PRIOR TO USE FOLLOWING ANY REPAIRS TO THE TRENCHER, OR THE PARENT MACHINE IF A LEAK IS DETECTED WHILE CONNECTED TO THE TRENCHER. DO NOT ALLOW THE TRENCHER TO RUN WITHOUT OIL AT ANY TIME. NOSE ROLLER BEARING REPLACEMENT FIG FIG 2 FIG 3 2. Use a press to push the bearing out ensuring the pipe underneath is larger than the bearing Fig 2.. To replace the nose roller bearing, firstly remove circlip using a pair of straight circlip pliers Fig. NOTE: A HAMMER IS NOT RECOMMENDED FOR THIS PROCEDURE AS IT CAN DAMAGE THE NEW BEARING. 3. When pressing the new bearing in ensure the drift used is the correct size. ie; The drift must sit against the outside shell of the bearing being careful not to damage the ring that holds the bearing together, make sure the bearing is sitting against the lip on the opposite side of the nose roller and replace circlip. SCRAPER SHOE REPLACEMENT SCRAPER SHOE (PLASTIC) The Scraper shoe is designed to be able to flip end for end when worn. This gives the operator an extended use before replacing. To either flip or replace the shoe remove the 3 bolts. With a new shoe, it may be flat when purchased. To mould this into an arc form simply place shoe between the jaws of a vice and over bend, replace bolts bottom first. HEAVY DUTY SCRAPER SHOE (METAL) The Heavy Duty scraper shoe is designed to be used with the Hydrive XD and the Bigfoot XD. 9

10 MAINTENANCE SPROCKET REPLACEMENT FOR BIGFOOT FIG Firstly remove ½ bolt holding the auger, then remove auger. Using a 3/6 Allen key loosen the 2 grub screws in the retaining collar and slide collar off the shaft. (shown in Fig ). FIG 2 Slide the sprocket off the shaft and replace with new sprocket. It is recommended Anti-seize be applied to shaft before replacement of sprocket (Shown in Fig 2) SPROCKET REPLACEMENT FOR HYDRIVE FIG 3 Firstly remove ½ bolt using a spanner, remove the spocket washer and then slide sprocket off the shaft. (shown in Fig 3). FIG 4 Slide the sprocket off the shaft and replace with new sprocket.

11 A B MAINTENANCE NOTE: IF THE SPROCKET CANNOT BE REMOVED BY TAPPING WITH A HAMMER THEN A PULLER MAY HAVE TO BE USED. IMPORTANT: SHUT DOWN TRENCHER & MACHINE BEFORE ANY ADJUSTMENTS ARE MADE HYDRAULIC HOSE CONNECTION BOOM ADJUSTMENT SUPPLY FROM MACHINE. The Trencher chain must rotate in an anti-clockwise direction (when viewed from the Motor side of the Trencher). The Supply Line from the Parent machine must be connected to the A port on the Trencher Motor. Use spanner supplied to wind adjuster nut clockwise for loosening, anti-clockwise for tightening

12 MAINTENANCE CHAIN ADJUSTMENT. To either adjust chain or remove chain remove the ½" Bolt holding spanner to outer boom. 2. Use spanner supplied to wind adjuster nut clockwise for loosening, anti clockwise for tightening. Chain midway point between sprockets 3. To achieve the correct chain tension: Adjust the tension on the lower chain section at the midway point between the sprockets to allow 5mm of vertical movement. 5mm SCRAPER ADJUSTMENT. The adjustment of the scraper/chain gap via the inner danger bar is done by removing the bolt with two ¾" spanners at the end of the outer danger bar. The inner danger bar is moved out and the bolt relocated in the second or third hole. 2. The three holes in the inner boom to allow for Scraper adjustment. The hole indicated is the setting from the factory. 3. Use these holes to adjust the scraper distance when the gap becomes less than 00mm. 00mm 4. The gap between the chain teeth and scraper plate should be at least 00mm to prevent any binding. 2 Trencher: Service and Repair Manual - 203

13 SEAL REPLACEMENT MAINTENANCE FIG Before the seal can be replaced remove retaining collar and sprocket as shown in sprocket replacement. Then remove the key and seal protector. Place a screwdriver between outside of seal and inside of housing. Tap gently with a hammer until the seal can be levered out Fig. Inspect the inside of the housing for damage and if damaged or burred, clean up with emery cloth. FIG 2 FIG 3 Before the seal can be replaced run some grease around the inside lip of the seal for lubrication to the shaft. Ensure there are no burrs on the shaft between the end of the shaft and the end of the housing. File if necessary. Using loctite 243 (or equivalent) run a small bead around the outside of the seal see Fig 2. Proceed to fit the seal by using a large punch and gently tap the seal into place ensuring the seal is punched in evenly (see Fig 3). This is very important as any misalignment could cause damage to the seal and promote a leak. The seal must be flush with the end of the housing. Replace seal protector, key, sprocket and retaining collar. Refill the planetary with gear oil (See lubrication for correct amount, grade of gear oil, and oil filling procedures). NOTE: MAKE SURE ALL GEAR OIL IS DRAINED AT THIS POINT. AUGER ADJUSTMENT. The spoil removal Auger is double ended. When a 50mm or 200mm chain is being used. The Augers must be on the correct way around. This illustration shows the Augers being fitted with the narrow end closest to the chain. IMPORTANT When a 250mm or 300mm chain is being used it is important that the Augers are turned end for end and fitted with the wide end closest to the chain. If this is not done the chain may foul with the Augers. 3
