How to remove drive sprochet nut

Remove black rubber look for the 2 two mounting bushes on either side and fasten the drive gear in a vise and unscrew the head nut at the front then pull the mechanism out completely.

Its not hard! You need to purchase a tool that goes into your spark plug hole. You remove the spark plug, put this tool in the hole. This tool stops the piston from moving so you can remove the nut holding the clutch. The clutch is what the drive sprocket is attached to. The drive sprocket is where the chain fits on at the engine side. remive the bar and chain and you will see the clutch. Use the tool and then use a wrench that fits the nut on the clutch. be sure you know which way removes the nut. It could be opposite of what you think. some are left hand threads some are not. I think these are not. After you replace the clutch be sure to lube the clutch bearings. Most people don't know this! use a grease gun made for saws and insert it into the hole at the end of the shaft that holds the clutch. Also next time your saw cant saw through a piece of wood, do not give it gas to make the chain try and move.This is what burns up the clutch! If your saw stalls out, and you press the throttle and it still doesn't turn. Always allow the chain to move, pull back and lift up on the saw slightly to get the chain moving again.

p1340 means camshaft sensor is out of adjustment and the engine timing belt jumped a tooth.
make sure the #1 piston is at TDC(top dead center) and camshaft sprochet mark to corresponding mark. dont let the sprochet moves when installing timing belt.

This problem occurs when the second image transfer is preassure/retraction failure.

You have to:

1, Check the M1 connector
2, Check M1 for proper drive coupling
3, Check SL4 connector
4, Check PWB-A connector
5, PC5 sensor check
6, SL4 operation check
7, M1 operation check
8, Change PWB-A

Chain saws don't have an arbor. They do have covers over the clutch system that drives the chain that are held on by two (sometimes one) nuts. You only have to remove the cover to change the chain, not the clutch. The nuts are the normal lefty/loosey righty/tighty on all the chain saws I've worked on. Can't say much more without knowing what kind of chainsaw you have.

You should have a stamped metal box-end wrench that came with the saw. Place it over the blade retaining nut, and drive the motor belt by hand to allow the wrench to tap on the table behind the blade. This will loosen the nut so that it can be removed by hand (this is a left-hand thread situation). Tightening the nut is the reverse operation and it is not necessary to drive the nut tight with a hammer--it will tighten enough during saw operation. A safety manual will say to remove power from the machine when doing this! Hope this helps!

Remove the side cover on the saw Should be 2 nuts on studs

Either in the front between the bar and the saw body or in between the nuts on the side is a chain tightener. Use a flat bladed screwdriver to loosen the tightener and remove the chain from the drive and the bar. NOTE the direction of the chain teeth.
Replace with new or sharpened chain Reinstall the side cover Install the nuts DO NOT TIGHTEN just snug to contact Adjust chain to where you can just pull the chain free of the bar at the center of the bar length Tighten the nuts
Happy cutting!

I'd try that site for any help or parts for this Grand Old Lady.

I did a search for "Remington SL4" and found quite a few threads here:
