QuestionQUESTION: I have a Honda HRA214 SA from the mid '80's with a GXV120 engine that I am trying to get into the crank case to do a ring job. I have the engine off of the mower, but i can't figure out how to remove the blade brake from the shaft so I can get into the crank case. I have seen the diagram, but it is still not clear to me. I have removed the bottom bolt that appears to hold the bearing on the crank shaft. Do i just use a puller to force the brake mechanism off of the shaft, or is there something else that I'm missing?
ANSWER: Hello John:
>>It Sounds like the Woodruff Key has Rusted to the Blade Clutch/Brake.
>>Soak the Crankshaft with PB Rust Blaster or Liquid Wrench so it will SLow to the Woodruff Key and Allow the Penetrating Oil to Work for a Few Hours.
>>Now Attach a Puller to the Blade Clutch/Brake and Apply Light Pressure to the Puller.
>>Lightly Tap the Blade Clutch/Brake and Increase the Pressure to the Puller.
>>Be Carefull and Do Not Damage the Clutch/Brake Assy.
>>I have had to Replace the Clutch/Brake Assy on Some Mowers Due to the Clutch/Brake Assy being Seized to the Crankshaft and there was No Other Choice than to Damage the Clutch/Brake Assy in Order to Remove it from the Crankshaft.
>>To Prevent this Problem in the Future, Apply a Light Coat of Never-Seize to the Crankshaft.
>>This Prevent the Woodruff Key from Rusting and Seizing the Clutch/Brake to the Crankshaft.

QUESTION: Thanks John. That was it and I am now into the crankcase to replace the
rings (my first time attempting). The crankcase looks very clean with no
sludge at all. The piston is not burned and the cylinder is very smooth
with no gouges.
How important is it that I hone the cylinder before installing the new rings?
Are there any other tips that you can give for this engine (Honda
GXV120)?
AnswerHello Again John:
>>It is VERY IMPORTANT that you Hone the Cylinder before you Install the New Rings.
>>The Honing of the Cylinder Roughens Up the Cylinder and makes it so the New Rings can Seat/Seal Correctly to the Cylinder.
>>As for Tips, Make Sure to Keep the Engine and Components as Clean as Possible when Assembling the Engine.
>>Use the Correct Bolt Torques.
>>All these Small Engines are Simple to Repair/Rebuild and there are Really No Short Cuts when Doing a Repair/Rebuild Correctly.
>>Be sure to Lap in the Valves and Set the Valve Clearances Correctly.
>>As Always, 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. I Hope you Had a Happy Holiday and May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.
