SERVICE
Grease
Use grease based on the expected air temperature range during the service interval.
The following greases are preferred:
· John Deere Moly High Temperature EP Grease.
· John Deere High Temperature EP Grease.
Other greases may be used are:
· SAE Multipurpose EP Grease with 3 to 5 percent molybdenum disulfide.
· Greases meeting Military Specification MIL-G-10924C may be used as arctic grease.
Gear Oil
Use oil viscosity based on the expected air temperature range during the period between oil changes.
John Deere GL-5 Gear Lubricant is recommended.
Other oils may be used if they meet one or more of the following:
· API Service Classification GL-5.
· Military Specification MIL-L-2105D.
· Military Specification MIL-L-2105C.
· Military Specification MIL-L-2105B.
Oils meeting Military Specification MIL-L-10324A may be used as arctic oils.
Adjusting and Lubricating Drive Chain
c CAUTION: Avoid injury! Do not operate snowblower without chain shield.
|
5. Push chain shield left to provide tension on the chain. Deflection should be 4.7-10 mm (3/16-3/8 in.).
6. Adjust chain, if necessary:
· Loosen chain shield (A) by loosening four lock nuts (B) on chain shield.
· Slide chain shield right or left until deflection measurement is right.
· Hold chain shield in place and tighten nut.
7. Rotate snowblower several turns and make sure chain has at least 4.7 mm (3/16 in.) deflection at all times.
8. Lubricate chain with John Deere TY6240 Chain Lube Spray or equivalent.
9. Start engine. Run snowblower briefly to distribute oil.
10. STOP engine. Wipe off excess oil.
11. Check condition of chain and sprockets.
Checking and/or Adding Gear Box Oil
1. Remove filter plug (A). Oil should be even with bottom of hole.
2. If oil is low, add 80W-90 GL-5 Gear Oil.
Lubricating Auger Shaft
· Lubricate grease fittings (A) with John Deere Moly High Temperature EP Grease or an equivalent.
Lubricating Driveshaft
Lubricate driveshaft grease fittings with John Deere Moly High Temperature EP Grease or an equivalent as shown:
Replacing Shear Bolt
When auger hits an object, shear bolt may break. This helps prevent damage to rotor and snowblower. If you break a shear bolt, do the steps listed below:
IMPORTANT: Avoid damage! Replacement shear bolts MUST BE same as original shear bolts on your snowblower: |
1. DISENGAGE PTO to stop snowblower immediately.
3. Lower snowblower to the ground.
6. Wait for ALL moving parts to STOP.
7. Remove broken shear bolt (A), one on each end, or (B) in center.
8. Turn auger or blower impeller to line up holes in shaft. Remove spare shear bolt (C) from snowblower.
9. Install bolt and nut. Tighten so that the two paddles that the shear bolts connect are touching. DO NOT OVERTIGHTEN nut.
10. Find and correct the cause for shearing.
Reversing and/or Replacing Scraper Blade
1. Check scraper blade for wear or damage.
3. Place wood blocks under collector assembly.
4. Lower snowblower onto blocks.
5. Remove nuts from carriage bolts (A).
6. Turn scraper blade (B) end-for-end or replace blade if both sides are worn.
8. Tighten nuts on carriage bolts.
Removing Discharge Chute Cables
NOTE: When removing the black cable shield (A) an angle bracket will fall from underneath the snowblower. This bracket needs to be installed again when the black cable shield is installed.
1. Remove black cable shield (A) and angle bracket by removing four hex head bolts (B) and lock nuts.
2. Loosen two lock nuts (C), from threaded studs on discharge chute.
NOTE: For ease of reassembly and proper cable routing, remove one cable at a time.
3. Remove each cable (D) from snowblower.
4. Remove cables from pulleys (F).
5. Install new cables on pulleys. (See Replacing Discharge Chute Cables in this section.)
Replacing Discharge Chute Cables (Right-Hand))
NOTE: For ease of reassembly and proper cable routing, replace one cable at a time.
When replacing discharge chute cables, route RIGHT-HAND cable around snowblower FIRST.
IMPORTANT: Avoid damage! Hydraulic cylinder plunger MUST BE in the RETRACTED position (all the way in the cylinder) when beginning this procedure. |
1. Turn snowblower discharge chute to the left (as viewed from the tractor seat.
2. Standing at the rear of the snowblower, put cable (A) through hole (B).
3. Wrap cable around middle pulley (C), and around right-hand pulley (D).
4. Wrap cable counterclockwise around discharge chute and put it around threaded stud and behind washer and lock nut (E).
Replacing Discharge Chute Cables (Left-Hand)
NOTE: For ease of reassembly and proper cable routing, replace one cable at a time.
IMPORTANT: Avoid damage! Hydraulic cylinder plunger MUST be in the RETRACTED position (all the way in the cylinder) when beginning this procedure. |
1. Turn snowblower discharge chute to the LEFT (as viewed from the tractor seat).
2. Standing at rear of snowblower, put cable (A) through hole (B).
3. Wrap cable around middle pulley (C), and around left-hand pulley (D).
4. Wrap cable clockwise around discharge chute and put it around threaded stud and behind lock nut and washer (E).
IMPORTANT: Avoid damage! Make sure you install the long bolts through the black cable shield and bracket. |
5. Install cable shield (F) and angle bracket and fasten with four hex head bolts (G) and lock nuts.
Service Lubrication Intervals for the Broom
Grease
Use SAE multipurpose EP grease.
Lubricate Wheel Bearings and Spindles
Lubricate four points (A) with John Deere Multipurpose grease or an equivalent (two on each wheel).
Lubricate Driveline U-Joint
Lubricate points (A) with John Deere Multipurpose grease or an equivalent.
Check Gearbox Oil level
NOTE: You do not have to change gearbox oil.
Left brush sections removed for photo.
1. Remove plug (A) when oil is cold.
2. Oil should be level with plug hole.
3. If needed, add John Deere GL5 - 80W-90 gear oil or other gear oil meeting API GL5 - SAE 80 W-90 classification.
Replace Shear Bolt (Brush Section)
NOTE: Shear bolt for driveline is longer than the brush shear bolts.
Location of the extra shear bolts is in the frame rear.
1. Remove part of shear bolt from end of driveline.
2. Install shear bolt and lock nut (A).
Removing Brush Sections
Replace sections when they are worn to 229 mm (9 in.) diameter.
2. Use a safe method of holding broom on its back.
NOTE: To remove locking collars, use a punch in countersunk hole. Tap with hammer until loose.
3. Remove allen screw (A) and rotate locking collar on each side until free.
4. Remove eight screws (B) and end plate on each side.
5. Remove lock nut and shear bolt (C), two screws (D), and retainer (E).
6. Remove spacers and brush sections.
Install New Brush Sections
