Can't get clutch plate off of makita 340 dcs

What tool do i need to remove the clutch plate from a makita 340 dcs? I can get the nut from the bolt by rotating it clockwise, but then, the clutch plate moves in syncronicity with the threaded shaft, so i have no way of moving the threaded clutch plate in the opposite direction of the threaded shaft, in order to remove it. I am in north east canada. my email is

You need a piston stop to stop the engine from rotating,then with a clutch tool you can spin off the clutch,most of them are left had thread.if you don't have a clutch tool you can use a hammer and punch on one of the main arms of the clutch itself.for a piston stop you can use a piece of 1/4"rope.put the piston at the bottom of the stroke and stuff the rope in the sparkplug hole,this stops the piston from reaching it's full stroke.

Makita LS1030 (not LS1030N) won't turn.

The nut is not on the bottom, but under the snapout kerf plates. You remove the plastic kerf plates to access the bolt. Once you remove the nut the turntable will lift straight up and off. Check the stainless steel wear plate at the rear for burrs or wear.
Do not use oil or wd40 etc - it will collect sawdust and cause problems down the road. I recommend a pure silicone spray that will dry completely and provide lubrication.

How to replace a clutch drum on an 09 Electra glide

Pull primary cover and then pull primary chain adjuster and compensator and clutch and chain out and then remove six metric bolts and remove clutch pressure plate and discs and then replace hub and bearing assembly and replace clutch disc and pressure plate etc as you took them apart. Might not cost that much more to simply buy a whole new clutch assembly and have it all new. You will need a bar to lock the primary and compensator together when you loosen and when you tighten the retaining fasteners.

Tighten compensating sprocket bolt to 100 ft-lbs (135.7 Nm) and then reverse the drive locking tool and loosen the bolt one full turn and then reverse the locking tool again and tighten the bolt to a final torque of 140 ft-lbs (190.0 Nm). Install the locking tool again and tighten the clutch hub mainshaft nut to 70-80 ft-lbs (94.9-108.5 Nm).
After the compensator and clutch fasteners have been torqued Install the primary chain tensioner and tighten the fasteners to 15-19 ft-lbs (20.3-25.8 Nm).

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.

If you just want to remove and replace the clutch plates then no special tools required just open the cover remove the pressure plate bolts and start removing old plates and then replace with new ones in exactly same way - tip with installing new clutch plates - soak them in oil few hours at least best over night before you install them back in -
If how ever you want the clutch hub and clutch basket off as well for some reason then you will need a clutch holding tool as well as you rarely could undo the lock nuts with out it
when changing your clutch plates go slowly take care and special notice to how it is all coming apart. from model to model sometimes there can be a little spacer or little spring or little ball bearing somewhere that with out care and attention may fall on the floor so go slow give notice to the order of the parts as they come out and you will have no dramas at all, as is reasonably simple job to do
good luck regards Jamie

Need to remove and install inner primary cover

You really need a manual for this job if you have never done it before. readers digest version is as follows. Drain Primary Fluid, remove outter primary cover, Remove compensating Nut its the one on the front, use a snap ring plyer on the clutch, remove the clutch adjuster nut rod plate . will come out in one piece, Remove the Chutch Hub Nut it turns opposit ( in other words tightening is loosening it) remove bolt on the chain tensioner, whole system will now pull out.
Leave the stator magnet on dont have to remove thats the silver plate up front. Remove the jack shaft bolt on the starter pull it out. Go to other side of bike remove two starter bolts you will need LONG allen..then remove all the bolts on the inner primary and remove it. If you dont understand any of this you need a manual for your bike. or any Harley FL its all the same.
