Small Engines (Lawn Mowers, etc.): scotts 2546h governor replacement, sectional index, 6 digits


Question
my scotts mower 2546h is at full throttle no matter what throttle is set at.  The linkage is intact and all springs are in place.  I have adjusted the governor by turning shaft clockwise with carb at wot.  this did nothing to help.  I ran engine manually with the governor arm loose but got no feedback from governor shaft no matter what engine speed was.  Am I correct in assuming the governor gear is broken or misaligned with governor shaft?  If so could you please help me with a link or procedure to replace internal governor gear?

I have read your discussions on governors and believe the problem is internal.

thanks

Answer
Hello CW:

From you Description and After Viewing the Breakdown for this Unit, it Sounds like the Internal Governor has Broken and Requires Replacing.
You can View a Breakdown/IPL of the Engine and Mower at this Site Addy, http://jdpc.deere.com/jdpc/servlet/com.deere.u90490.partscatalog.view.servlets.H... and Enter the Model Numbers (Scotts)and Click Find. Then Select your Model from the Search Results Area. Then Select the Sectional File. Then Select the Section of the Mower you Wish to View Online.
You can View a Breakdown/IPL of this Engine at this Site Addy, http://www.smallenginepartswarehouse.com/parts.asp and Select the Shop Online Parts Look Up. Then Select the Model Tab. Then Select the OEM and Enter the Model (5 or 6 Digits) and Type Numbers (first 4 digits Only). Example: 445777-0027. Then Double Click on the Model in the Results Area. Select Sectional Index. Now you can Select the Section of the Engine you Wish to View. Select the Controls, Electric Starter, Flywheel, Governor Spring File. The Internal Governor is Shown as #219 in the Breakdown.
The Following is a Basic Instruction File for Examining the Inside of a Small Engine and will Assist you in having Access to the Governor, Oil Pump (if Applicable), Cam and Crankshaft Gear. Any Input is Appreciated. **This is a Simple Process. Drain the Oil and Remove the Engine to the Work Bench with the Oil Pan Facing Up. I have a Wooden Rest that was Especially Made to Hold the Engine when in this Position. Using Fine Sand Paper, Remove ALL the Rust and Debris from the Crankshaft. Remove the Oil Pan Bolts. After All the Oil Pan Bolts are Removed; Tap Lightly on the Sides of the Oil Pan to Loosen it from the Dowel Pins. When the Oil Pan is Removed, you can See the Governor Resting on Top of the Cam Gear. ****If Required: Lift Off and Replace with a New Governor. Check the Engine Block for Debris from the Old Governor and Wipe the Inside of the Block With a Rag, Until Clean. Set the Governor Shaft So it will be Resting on the Governor whine the Oil Pan is Replaced and Carefully Replace the Oil Pan. If the Crankshaft Seal Was Not Leaking, then Leave it Alone. It Should be OK. You can Easily Replace it While Mounted on the Machine if Required Later. Make Sure the Governor Stays in Contact with the Governor Shaft while Replacing the Oil Pan. Re - Mount the Engine to the Machine. Refill With Oil. Your Internal Governor May Differ.**
Please, Do Not Hesitate, If you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck
