It may be a left hand thread. In normal motion, the drive should tighten the nut. This sometimes results in having a left hand thread. Bicycle pedals are a prime example, one is right hand and one is left hand. Give it a sharp tap CLOCKWISE.

Maintenance Manual if it is any use?

The compensating sprocket nut is indeed right hand threads. It is torqued to 150-165 foot pounds of torque and usually has Locktite 271 (red) in it. A lot of mechanics go overboard with the Loctite. I've seen the entire inside of the nut "painted" with this stuff. The book calls for "two lines" of the stuff when putting the nut back on.

The easiest way to get the nut off is with a GOOD air wrench. I bought one of those Ingersol-Rand Titanium air wrenches. I've seen nuts on so tight that I've had to use a 3/4" air wrench to get them off. If you don't want to purchase an air wrench, load the bike on a trailer and take it to a tire store. Ask them to take the nut off for you. Usually they'll do it free but they may charge you a couple of dollars. It is worth a couple of dollars to get the nut off.

When putting the bike back together, the compensator sprocket torques to 150-165 ft lbs. of torque with two lines of 271 Loctite in it. The clutch hub nut torques 60-80 ft. lbs. left handed with one line of 271 Locktite. Make sure your torque wrench will torque in the left handed direction. Not all wrenches will.
Good Luck.

SOURCE: how do i remove the cam chain off the sprocket?

Remove the spark plug then put the piston at Top Dead Center compression. Look at the position of the timing marks on one side of the cam, parallel with the gasket surface. Remove the cam as you described.

SOURCE: cant undo nut

No they are not left hand thead,normal r/h thread.
make sure chain is still on bike and front sproket and then try good rattle gun. if this does not work,put bike in gear and hold on rear brake and use long breaker bar, if still no good will need to heat front sproket nut with oxy set very carefully and rattle off with rattle gun while nut is hot

No, But they do offer a real nice chrome cover for them. Much less expensive than chrome plate. You can get one at your local Harley dealer or most any cycle shop can order you one from aftermarket supplies like Custom Chrome or Drag Specialties.

95 gpz chain tighten how to

hey Dominico,
This is the way PROFESSIONAL mechanics do a chain/sprocket check and drive chain alignment and tension.. Proper chain tension is very important to the life of your chain and sprockets and performance of your bike. First, you need to check to see if the chain/sprockets need replacing. (Chain and sprockets are ALWAYS replaced as a set (-all-3)..if you replace a chain on worn sprockets.. the chain will stretch out QUICK.. and if you put new sprockets with a worn chain.. the sprockets will be worn out QUICK too!!) ...To do this..the bike needs to be on the center stand or bike stand...NOT on the side stand... the chain guard-- next..Sprocket check time - take one hand and squeeze the chain (grab the chain above and below the swingarm) at the point between the axle and the swingarm bolt.. as hard as possible. to take all the slack out of the chain and put the tension completely around the back sprocket.. while you are squeezing the chain as hard and tight as possible.. - with your other hand - try to lift/pull the chain off the rear sprocket.. IF you can pull the chain off enough to see if there is a .200" or 5mm max. gap between the chain and sprocket - under the chain... or MORE THAN A HALF a tooth groove under the chain..or the chain pulls up more than two teeth...OR the teeth on either sprocket are "pointed thin" or rounded need to replace the chain/sprockets.
...ONCE you are sure the chain/sprockets are good..its time to CORRECTLY align and adjust the chain tension. Loosen the axle nut.. DO NOT remove it.. now - tap it gently to make sure its loose...loose the chain adjuster nuts.. back them off a good bit, but do not remove may,also need to loose the rear brake caliper mounts should be able to move the rear wheel forward and backward with your hand.(this is to assure you have sufficient "looseness" to make the proper adjustment...NOW - pull the rear tire backwards until it stops.. - run the adjuster nut(s) until they are just snug..ALIGNMENT - This is CRITICAL - (did you remove the chain guard yet?) - do that now. You must be able to see down the entire length of the chain (above the swingarm)..The chain MUST RUN IN A STRAIGHT LINE!! .. The little marks on the swingarm are just "guides".. never use them as perfect.. the only way to assure CORRECT ALIGNMENT is a visual check of the chain to make sure its in a straight line!!!! - ...ANY bend, crook, or mis-alignment will cause premature wear and tear, and make it harder for your engine to make it turn. - Now - Rotate the wheel and find the tightest point of the chain... there is one, and its normal... LEAVE the tight point located between the two sprockets on the top of the swingarm. This is where you will "feel" for the correct tension.
The biggest thing most people miss when adjusting the tension is having the AXEL/NUT and the SWINGARM PIVOT SHAFT and the COUNTERSHAFT C/L (front sprocket shaft) IN A STRAIGHT LINE - ALL THREE ARE ON THE SAME PLANE!!!!!
. NOW, You may have to get a buddy to help pull the swing arm up.. (I use a tie down strap through the rear wheel and over the seat pulled tight enough to make AND KEEP the STRAIGHT LINE!!)
..Once you have established the straight line - --- - --- - and MADE SURE the chain is RUNNING STRAIGHT on both sprockets.. NOW _ its time to adjust the tension. There WILL be a tightest and loosest point of the chain..(normal).. you MUST adjust the tension using the TIGHTEST point of the chain....set the tension so you can move the chain up and down (total movement) about 1 3/8 inch to a max of 2 inches!! Once you have established the chain is straight and the tension is correct, its time to TIGHTEN EVERYTHING in order... start with snugging the axle nut.. then snug the adjuster nuts more..-- DOUBLE CHECK you chain alignment.. now - tighten the axle - TIGHT!!... tighten the adjuster nuts..lock down the lock nuts.. tighten the caliper.. TRIPLE CHECK the alignment... double check the tension...double check all the nuts... install the chain guard... REMOVE whatever you use the keep the straight line straight..

KNOW you have done a job correctly!! (I am a factory trained mechanic, race engine builder, port work guy, race tuner.)..

Timing chain cover

the fix will be to remove the timing cover and that will leave the broken bolt as an extension which you can grip with a pair of vice grips to undo

Procedure for chaincase removal front sprocket inspection 2002 1200s gfs

Remove the gearbox sprocket cover, this may mean undoing the gear lever, First put the bike in gear. This will lock the sprocket so you can undo the securing nut, you will also need to loosen the rear axle to allow the chain to be taken off the sprocket. Then remove the sprocket, refit is the same process in reverse. I would suggest you change the complete set (front & rear sprockets and the chain) that way you only have to take it to bits once. And it will also mean the chain lasts longer as the wear will be the same at both ends.

Need to put a new chain on a Husqvara 235 14 inch chain saw?

Check that the chain brake is in disengaged position by
moving the front hand guard towards the front handle.
Remove the bar nuts and remove the clutch cover (chain
brake). Take off the transportation ring.
Fit the bar over the bar bolts. Place the bar in its rearmost
position. Place the chain over the drive sprocket locate it in
the groove on the bar. Begin on the top edge of the bar.

Make sure that the edges of the cutting links are facing
forward on the top edge of the bar.
Fit the clutch cover (chain brake) and locate the chain
adjuster pin in the cut-out in the bar. Check that the drive
links of the chain fit correctly on the drive sprocket and that
the chain is in the groove on the bar. Tighten the bar nuts
Tension the chain by turning the chain tensioning screw
clockwise using the combination spanner. The chain
should be tensioned until it does not sag from the
underside of the bar.
The chain is correctly tensioned when it does not sag from
the underside of the bar, but can still be turned easily by
hand. Hold up the bar tip and tighten the bar nuts with the
combination spanner.
When fitting a new chain, the chain tension has to be
checked frequently until the chain is run-in. Check the
chain tension regularly. A correctly tensioned chain
ensures good cutting performance and long life.

I cannot get the automatic chain lube to work - it is a mac 335 chain saw - any ideas

The pump is fairly simple, however you will need to remove the clutch and sprocket to gain acsess to it, start by removing the two bar nuts and the chainbreak side cover, remove the guide bar and chain, the clutch is just spun onto the crank left hand thread, there are two cut a ways in the clutch centre, this is to take a special tool, once inserted into the cut a ways you use a 19mm spanner to jar the clutch off against compression, an impact wrench works well, the tool is part no. 530031112, you could maybe make a pin spanner to do the job, once the clutch is removed the sprocket will just pull off, there are then two cross head screws securing the pump assembley, the drive gear is pressed onto the crank, the pump pinion runs at right angls to the drive gear, the pinion is nylon so check the condition of the gear, behind the gear is the pick up pipe and filter, you will need to pry off the silver bar protection plate.

Having problems undoing front sprocket ! Would it be left-hand thread Also cant get socket on very far do i need a special socket as its got two different sizes 27mm on first part of nut and 32mm on rear...

There should be a bent washer over the nut to stop it from turning. Have a good look.
Flatten the bent washer with a flat cold chisel, gently, as you need it again! Put the bike in top gear to hold the sprocket and use a spanner 27mm to undo the nut. It is a clockwise thread.
When you put a sprocket back on, don't forget the bent washer and a drop of Loctite Threadlock will help to hold it on.

Hi. My problem is that i dont know hw to tighten my chain of my nc30 vfr 400r.can u please assist me in telling me how i go about in doing that?

hi, yes i can help. the chain is adjusted by turning the ecentric nut at the back of the rear sprocket, if you look carefully you will see a large caselated nut, you will need a C spanner to perform this operation, undo the 17mm bolts in the rear hub to alow the ecentric to turn, place your spanner on the nut and pull upwards from the rear of the machine untill you reach a prefered chain tension of about 30mm slack, then reetighten the bolts in the midle of the eecsentric rear hub.WARNING DO NOT USE A CHISEL OR SCREWDRIVER ONLY A PROPER C SPANNER SHOULD BE USED ON THIS NUT.
