Recoil rope replacement on Ryobi 825R. I am a pretty good mechanic. But unable to remove clutch hub from the shaft. Have removed the drum and shoes. Cannot pull the center (hub)off the shaft. What is the secret?

Fix Factor: EasyDuration: 25-30 minutesFrequency: As necessaryTools Required: Receptacle for draining fuel, Phillip's screwdriver, ratchet and socket set, Torx drivers, starter rope (or similar object), spark plug wrench or socket, adjustable pliers, long-nosed pliers, shop rags.

FLYWHEEL REMOVAL:

Use long-nosed pliers to remove the washer from the shaft.

While applying steady upward pressure to the flywheel, firmly strike the end of the shaft with a rubber mallet until the flywheel breaks free. Several blows from the mallet may be necessary to free the flywheel from the engine assembly.

The starter rope normally rewinds automatically when the recoil unit is functioning properly. If the pull rope has stayed out, disassembly will be required. Here are instructions for that problem. The recoil spring can break and is replaceable, but the nylon hub in the starter recoil unit is usually the problem or the rope has broken and jammed inside.
Remove the tube that holds the flex-drive shaft from the front of the motor cover.Remove the rear engine cover. Remove the throttle cable from the carburetor. Mark and unplug any wires for the on/off switch that go to the ignition coil (underneath front cover) if possible. Now if you have pulled the driveshaft tube out of the way, the clutch drum is up next. Inside it, screwed into the very end of the engine's crankshaft is a Torx #25 screw. Before you loosen it, you will have to lock up the engine. To do so, remove the spark plug. Pull on the starter until the piston is down, then insert a length of clean, soft rope into the engine. The engine will come up and compress the rope, thus locking it in place to allow clutch drum and clutch removal. Loosen the T-25 (Star bit or Torx head) screw inside the drum.. You may be able to remove it with a long thin-blade screwdriver also.It probably won't come completely out...it is made this way. Next, remove the clutch. It is screwed onto a small threaded section of the crankshaft Removal is counterclockwise.. It will be pretty tight. To help, apply peneterating oil. Whack the ears of the clutch near the center with a hammer and a dull flat-blade chisel or a small piece of wood unless there are bolts. then use a wrench. It will turn counterclockwise for removal and there will probably be a removal direction arrow on it's face. After getting that off, remove the Torx screws holding the cover to the engine. The starter unit should be mounted inside as it mates with the top of the flywheel to start the motor. Remember to preload tension (5-7 turns) on the starter unit. Make sure the handle is installed. Jam the unit with a screwdriver or vise grips so you can insert and tie off the new rope. Then remove jam device and let recoil pull your new rope into place while holding the handle. Reassemble and you are done. Disassembly requires Torx head drivers and a good flat-blade screwdriver. Here are more details for servicing the starter/recoil unit....With the starter/recoil unit OFF the machine, with no rope in it, and no tension on it.....grasp the little nylon hub and turn it (clockwise is I recall) round and round 6-7 times until you feel the recoil spring get nice and tight...DO NOT LET GO OF IT!...hold it in place and then JAM the starter/recoil unit in place (still tight) inside it's housing by either clamping it with a tool like vise grips or by sticking a screwdriver thru it and thru the vents in the cover. If you have ANOTHER person to help you...one of you hold it in place....and make sure it is lined up to where you can NOW insert the new lenth of pull rope. Always use new rope....Feed the end thru the hole in the recoil unit and tie it off, by wrapping it around itself outside the nylon hub and then screw the little self-tapping set screw back in holding the rope down. OK...then feed the opposite end into the hole in the front engine cover and attatch the T pull handle....Now mind you, you are still jammming or holding the recoil in place against the spring!...Now, unclamp it or unjam it and slowly let the recoil pull the NEW rope you just installed back onto the pulley. Make sure it is fastened well on top of the pulley around the nylon hub and also fastened well onto the T pull handle. That is it. Then reconnect your wires, put your throttle cable back thru the engine cover and reinstall the Torx screws in the cover...and you are doneervicing the recoil unitl

First off, here is an exploded parts view with part numbers and diagrams for the machine.

Secondly, the clutch does not enable the engine to run. It is a centrifugal clutch and only works when its speed reaches a certain RPM. It controls the string/blade head only. I am including all instructions regarding the removal of the clutch and pull start mechanism. It is up to you if it actually needs replacement parts.

With the proper tools, it is a moderate level project for the DIY mechanic. You will need T15, T20 and T25 torx drivers. 5/8" spark plug socket, Large lip-joint pliers, phillips head screwdriver, 40" of #3.5 rope and about an hour. Start by removing the shaft from the engine. Take pictures as you go. This will make reassenbly easier. The black housing removes next. This will expose the clutch drum. There is a T15 or T20 screw in the middle of the drum. It removes counter-clockwise. Next is the clutch itself. Remove the sparkplug and lower the piston to the bottom of the cylinder. Push as much of the old rop down into the cylinder as you can, then raise the piston up to "lock the cylinder. Now you can use the pliers to turn the clutch counter-clockwise to remove. Don't lose the little washer that is ontop of the clutch, or the thick washer that is under the clutch. Be careful with the clutch, you don't want to damage or misposition the springs on it. They are pretty difficult to reinstall. Next, remove the airbox cover and disconnect the throttle cable. Remove the remaining screws form the tan plastic housing and take it off. Inside this housing is the recoil pulley. Remove the pulley, install the new rope. Wind the rope on the pulley and pass the loose end thru the eye and tie on the handle. To tension the spring, install the pulley and wind more of the rope around the pulley. Reassmble in reverse order. Make sure to get the clutch tight. Failure to tighten the clutch properly can cause major damage.
Good luck!

remove spark plug put a piece of rope in hole to stop piston from moving there is a torx screw in center of clutch bell where drive shaft would go re move screw to remove bell use large channel locks or brass hammer to remove clutch assm still with rope in spark plug hole hope this helps

1) check oil supply holes in the bar
2) With the bar removed, run the engine for 30 seconds, does oil come out of the side of the saw.
3) If no oil on the side of the saw, inspect the clutch drive spring and worm gear on oil pump shaft

Outboard drums (drums on the outside of the clutch) are held on by a nut or e-clip.

Inboard drums are held on by the clutch which is threaded onto the crankshaft. And there is the challange.
***NOTE all chain saw clutches have LEFT hand threads, so, rightey loosey, lefty tightey. (just backwards from everything else)

*** NOTE #2: DO NOT USE AN IMPACT GUN
this will most certainly shear the flywheel key or damage the flywheel !!!!! (after 35 years, you can ask me how I know that, LOL)

1) Use a piston stop to hold piston from moving: THIS IS A MUST !!!
Ok, so you do not have one, let's make one.
a) remove the spark plug
b) insert a piece of recoil rope into the cylinder hole, leaving a tail to remove it by. (rope, large shoe string, anything that is soft, that is aprox 1/4 to 5/16 in diameter to place into the spark plug hole to help the piston to stop it's travel by filling up the empty space. Just make sure you can remove it later)
c) secure the saw (extra set of hands may be needed) and with a suitable wrench on the clutch center, rotate the clutch to the right until piston comes to a stop. With a hammer, tap the wrench to aid in rotation. This can be very difficult, and may take several taps.
d) after removed, inspect and grease the drum bearing before re-assemlby.
e) upon re-assembly of clutch, tighten by hand only, NO hammer required. The force of the chain will tighten the clutch.
f) remove the rope, and re-install the spark plug.
