To replace the drum you need to first remove the clutch, there are two ways to remove the clutch, fisrt by entering a flat blade screw driver into one of the two cut a ways in the clutch centre, these are designed for this, now use a suitable hammer to jar the clutch off against compression, the other way is with a workshop tool part no. 502541601, this fits into the clutch centre, it then has a 19mm nut on the end so as to use an impact gun to jar it off against compression, the clutch is just spun onto the crank with a left hand thread, it is then self tightning.

Partner 370 how to replace worn sprocket drive on clutch drum

You need to remove the clutch there is a special tool that fits into the two cut a ways in the sides of the clutch centre, the tool then has a 19mm nut on the other end this allows you to jar the clutch off against the compression of the saw, the clutch is just spun onto the crank with a left hand thread so it needs to be jarred off clockwise, an impact gun with a 19mm socket will work very well, the tool is part no. 530031112, should be available on the web.

How to remove the clutch & sprocket from Husqvarna chainsaw

The clutch type on Husqvarna chainsaws fall into two types, inboard clutch, this is where the drum is on the outside of the clutch, and held on with a clip, and outboard clutch, where the clutch is on the outside of the drum and holds the drum on. There are a number of reasons as to why you may need to remove the clutch and drum, to replace a broken spring, to replace the whole clutch,to lubricate the drum bearing, or replace the sprocket. On the pro saw range it is possible with outboard clutches to grease the drum bearing through the end of the crankshaft, there is a channel to the bearing from the outside, this is not possible on hobby, and domestic saws.
All Husqvarna clutches are just spun onto the crankshaft, with a left hand thread to make them self tightening, due to this they should NEVER be run with the bar and chain removed,and the clutch in place, or there is a very good chance the clutch will spin off on the over run, and can cause serious injury. Clutches should be jarred off against the compression of the saw, many have a 19mm nut on the outside so as to fit a socket, or the combination spanner supplied with the saw, the quickest way to remove this clutch is with an air impact wrench. If there is no nut on the outside, there will very likley be two cut a ways in the clutch spider, these are designed to take a flat screw driver blade, and with a suitable hammer you can strike the screw driver and jarr the clutch off, there is also a special tool for this type of out board clutch, it fits into the sides of the clutch with a 19mm nut on the outside part no. 502541601 available from Husqvarna dealers. The hobby saws from Husqvarna are produced in America, and as such use the Poulon clutch, this clutch should never be struck with a hammer, it is made from a sintered material and will shatter, there is a special tool to remove this clutch part no. 530031112.
The inboard clutch on the 371/372/365 also has a special tool available so as to use a 19mm socket, part no. 502522201.
The tool for the 357 clutch is part no. 502522202.
As a personal thing i never use piston stops, i have seen too much damage to internal engine parts when useing these, it is far better to jar the clutch off. As a rule of thumb you should not be able to pull the clutch shoes out by hand, if you can, the spring.springs are weak and require replacement, the clutch soes are also shamffered on there edge, the bottom of which is the wear limit.

Do i need any specal tools to change my clutch on myc90 suzuki

Check this
If you need to take apart just the clutch plates and replace them, you don't need any special tool.Just remove the right hand crankcase cover and the 5 bolts with the springs and pull out the pressure plate and replace the clutch plates.To remove the clutch basket (part #1 on illustrator), then you do need special tools such as air ratchet gun and the Suzuki special tool that holds the basket still, to remove the nut.

Ok, start by removing the side cover, there will be a large plastic nut with a flip up lever, undo the nut anti clockwise, now remove the guide bar and chain which are now free, there will be a c clip and washer holding the clutch drum on, remove the clip witha suitable screw driver, remove the large washer, the clutch drum will now just pull off, there is now a small washer to remove, you will now see the clutch, there is a special tool required to remove the clutch, it fits into the two half circle cut a ways in the clutch centre, the clutch is threaded onto the crank with a left hand thread, once the tool is fitted you put a 19mm spanner on the tool and jar it off against compression. The special tool is part no. 530031112.

It realy depends on wheather it has an internal clutch, or an external clutch, if the clutch is internal it is a straight forward job, start by removing the retaining c clip from the end of the crank, remove the washer, the drum shoud now just slid off, be carful not to lose the needle bearing, assembly is simply the reverse, if your machine has an external clutch you will need to remove the clutch first, there is normally a nut on the outside of the clutch, or two half circle cut-a-ways in the clutch centre, these are to take a special tool ( a cylinder with two pins and a 19mm nut on the top ) the part number of this tool is 530031112, the clutch is a left hand thread, undo clockwise, do not be tempted to use a screw driver or punch on the centre spider as it may snap the legs off.

How do i change my clutch and plates on a 1996 harley davidson roadking

On your '96 model, you need a special tool to disassemble the clutch pack. The tool is # HD-38515A clutch spring compression tool. Jim's and several other manufacturers make this tool. JP Cycle has a Jim's Part Number: 620-198 for $50.

Disconnect the battery and drain the primary. Remove any floorboards and other thing necessary to get the outer primary cover off. Using the above mentioned tool, compress the clutch spring and remove the lock ring that holds the spring in. Take note that there is a lock ring seat on top of the spring. This part is like a solid ring that goes behind the lock ring. It is "L" shaped so pay particular attention to the way it is positioned. Once you get the lock ring off, release the tension on the tool and allow the spring to come out of the clutch outer drum. Start taking the old disc out and laying them aside. Notice where the "sping plate" goes in the clutch stack. Replace it in the same position. Soak your new plates in oil overnight and then install them into the clutch drum exactly like the old ones came out. Install the spring and use the compression tool to install the lock ring and seat.

Adjust the clutch according to service manual directions and replace the outer primary cover. Add oil and reconnect the battery.

On my petrol chainsaw the cog that turns the chain is not moveing

The sprocket should be fixed to the outer clutch drum. With the engine off, and the bar and chain off, hold the sprocket with channel lock pliers and turn the outer clutch drum by hand. If the sprocket does not turn, but the drum does, then the clutch must be replaced. (Left hand threads) To keep the engine from turning while trying to remove the clutch internals, stuff starter cord into the upper cylinder head area so that the piston cannot rise above the top of the exhaust port. If you have a saw service shop near you, you might farm out the clutch replacement. It usually requires a special tool to turn the clutch internals. Good luck!

Need to replace clutch & drive sprocket

The threads are left-handed. Remove the spark plug and with the piston high enough to prevent entry into the exhaust/transfer ports, stuff some pull rope into the cylinder head and upper cylinder to block the piston from rising much further. You may need to get a special tool to remove the clutch core assembly--don't use an impact wrench as it will shear the flywheel key. If the clutch won't drive the chain and is full of oil, try washing the clutch drum out with spray carburetor cleaner and let dry. This might save the expense and trouble of replacing it. Hope this helps!

How to remove a clutch drum assy.

A serial would have been helpful. She has an outboard clutch (chain between clutch drum and engine). Use this as a guide:
R² Drive Link Outboard Clutch by
  1. Check the IPL for your saw to see if any special tools are needed. Poulan (Craftsman, Jonsered, Husky) clutch removal tool part number 530031112 if needed, is under $5 from many sources,
  2. There are metal piston stops available, when square (almost never) with the piston top these work well, if not square they have been known to punch through the piston. I suggest a length of starter cord or nylon rope 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 damage the piston as it rises.
  3. Everyone I have ever removed had a left handed thread (tighten it to loosen it).
This often helpful too:
Enter the 3 digit model number (no XPs, Es, just the numbers)
Serial number decode – useful when downloading IPLs and Manuals
06 1500198
06 = year produced – 2006 (single digit before 2000)
15 = week produced - March
00198 = 198th unit Husky produced that week
Good Luck, If you need any more help you can can reply below.
