Husqavarna rancher 55 repairs

Assuming you want to remove the clutch spider, which typically is left-hand threaded onto the crank. Not knowing if it's an internal (chain drive sprocket is "outboard") or external clutch, here goes for both. After removing bar & chain.
Internal: CAREFULLY (so it doesn't fly) remove clip from crank, remove washer, clutch drum, bearing and/or rim sprocket. Remove recoil starter. Using proper tool to fit clutch "spider" and impact wrench, turn it CLOCKWISE with wrench to unthread it.
External: Remove bar & chain and recoil starter. Using tool to fit the clutch "spider" and socket on impact wrench, spin the spider off CLOCKWISE. You can then remove remainder of clutch & bearing.
Be sure to grease the bearing while it's accessible.
Starter removal avoids applying any load if the crank turns.

too much load (too large a cut), dull chain, no lubrication oil on chain, slipping clutch.. lots of reasons.. need more information and you need to check all the points I mentioned. The clutch is RPM dependant- once the RPM drops- the clutch will start to slip. Look for oil or grease on clutch shoes also

The "clunking" you are describing is more than likely caused by either a faulty left drive sprocket, the drive shaft or a combination of both. The drive sprockets are equipped with a needle bearing type clutch. When they fail, the clutch does not grab the shaft and drive it correctly. You may just need to replace the left drive sprocket. In some cases you will need to replace the sprocket and the drive shaft.

take a look at the safety switch on the clutch/brake pedal jump it with a paper clip to test it

455 is an X Torq engine, this means it runs very cool on the inlet side of the piston, they are quite prone to gumming the ring in if they have been used on a heavy two stroke mix, due to the designit is a full machine strip down to get to the piston, skilled man 3 hours to strip and rebuild.

ether idlied to high or chain to loose

CHECK THE SCREEN ON OUTPUT OF THE MUFFLER. ITS CALLED A SPARK ARRESTOR, THESE GET OIL FOULED AND MAKE EM A BEAR TO RUN . CLEAN IT UP AND SHE WILL RUN LIKE A CHAMP, THE CARB MIGHT NEED REBUILDING ,FUEL FILTER AND A SPARK PLUG IS THE FIRST THING TO REPLACE .. IF'N I WAS ANY HELP VOTE FOR ME ...THANKS.. JAY

A YouTube video shows the procedure using a Husqvarna 350 here:

1. I looked at IPLs for the 55 & 455 and didn't see any special tools.
2. A length of starter cord or nylon rope may be used instead of the piston stop (retain 6" ± so you can remove it). Make sure the piston is near the top of the cylinder before feeding the cord or it can fall through the exhaust port and be cut when the piston rises.
3. It is probably a left handed thread (tighten it to loosen it).
Let us know how it worked for you. GL

It appears the 455 must be a "spur" type chain drive sprocket. the 55 offers the option of a "rim and spline" drive sprocket. If replacing the clutch drum I recommend the "rim and spline".

have you greased your clutch bearing ever.some times they get dirty and tighten up after running a while.pull your clutch off and clean and grease bearing with a little alex grease,and I mean just a few drops.not meant to have a lot of it,too much will burn the crank shaft and you will have more problems then you started with
