Installation Directions 

(Main Discharge Chute 108-4939 + Upper Deflector Procedure Style)

 

Hilly Ridge Sales & Service tech tip: Take 2–3 quick photos of the discharge chute rotation gear & bracket components, latch components, deflector linkage & control cable routing before you take anything apart. It makes reassembly faster and prevents confusion.

Safety / Prep

 

• Park on a flat surface. Shut engine off, remove key, and disconnect the spark plug wire or Battery.
• Let all moving parts stop completely. Wear gloves—sharp edges and packed ice can cut.
• Clean packed snow/ice from the chute base, ring, and gear area before disassembly.
• Take a visual Documentation of Parts (a quick phone photo helps).

 

A) Remove the Existing Chute Assembly

 

• Remove the chute mounting fasteners evenly. If the chute is stuck to the base/ring from ice, gently wiggle it free—avoid prying hard on plastic.
• Inspect Chute Ring and other Lower Chute Components - In Most Cases if Further Diagnosis is Need you will or May need to Remove the Plastic Engine Shrouds or Bumpers as well as Chute Ring Retaining Components Depending on Design Type - Due to Variation Between Models if Further Diagnosis or Replacement of Lower Discharge Chute Components are Needed Refer to the Diagrams Above and the Lower Chute Associated Part Reference Above to Determine the Usage and Placements of Associated Parts for Each Design Type Listed.

 

B) Transfer / Install the Upper Discharge Chute Deflector

* If your deflector (upper flap) and linkage are being reused, transfer them to the new chute now. If you are replacing the deflector components, install them onto the new chute before mounting the chute to the unit.

 

• Remove: The pin/springs/trigger parts as needed - All Components are Clip Together or Inter Fit to Retain Each Other - Hinge Chute Deflector Pin's Retaining Ring 104-8310 Pushes on and is Retained with Little Metal Reversed Locking Tabs that may Require it to be Bent out of Shape or Cut when Removing it off the Chute Deflector Pin so it is always Recommended Replacing it when Removing the Chute Deflector Pin (common: 136-8672 hinge pin, 104-8310 chute deflector pin's retaining ring, 136-7136 compression spring, 108-4941 trigger). * Chute Deflector can also be Un-Bolted from the Main Discharge Chute, Chute Deflector, Seal Erea and Independently Disassembled and Re-Assembled for Convenience.
• Transfer or Assemble: The pin/springs/trigger parts as needed - All Components are Clip Together or Inter Fit to Retain Each Other - Hinge Chute Deflector Pin's Retaining Ring 104-8310 Pushes on and is Retained with Little Metal Reversed Locking Tabs that may Require it to be Bent out of Shape or Cut when Removing it off the Chute Deflector Pin so it is always Recommended Replacing it when Removing the Chute Deflector Pin (common: 136-8672 hinge pin, 104-8310 chute deflector pin's retaining ring, 136-7136 compression spring, 108-4941 trigger). * Chute Deflector can also be Un-Bolted from the Main Discharge Chute, Chute Deflector, Seal Erea and Independently Disassembled and Re-Assembled for Convenience.

 

C) Install the New Main Discharge Chute (108-4939) to the Lower Ring / Base

 

• Inspect the chute ring/base and clean debris from the mating surfaces.
• Set the new chute onto the ring/base, ensuring it seats fully and evenly all the way around.
• Install mounting fasteners finger-tight first, then snug them gradually in a crisscross pattern (even clamping helps prevent distortion and stiff rotation).
• Do not overtighten screws into plastic—snug is enough to prevent cracking and to keep chute rotation smooth.
• If Further Replacement of Lower Discharge Chute Components is Needed Need you will or May need to Remove the Plastic Engine Shrouds or Bumpers as well as Chute Ring Retaining Components Depending on Design Type - Due to Variation Between Models if Further Diagnosis or Replacement of Lower Discharge Chute Components are Needed Refer to the Diagrams Above and the Lower Chute Associated Part Reference Above to Determine the Usage and Placements of Associated Parts for Each Design Type Listed.

 

D) Final Checks & Adjustments

 

• Rotate the chute fully left and fully right. It should turn smoothly without binding.
• Rotate the deflector fully up and fully down. Confirm it does not bind and the deflector holds its position.
  
• Reconnect the spark plug wire or Battery and do a quick functional test at idle speed only.
