The thread is RH, loosen the nut un till its just flush with the top of the crank threads, use an soft metal drift, copper, allly, brass etc.
hold the fly wheel and strike the top of the nut with the drift it will pop the fly wheel off. you may need a hand. if it wont come off use a screw driver under the fly wheel and pry it up when you strike the nut..Dont hit the nut /shaft without the soft will destroy the shaft.

the clutch thread is LH..

Dont split the cases! the bolts that hold the cover/bar on are square heads that sometimes fall back into the bar oil reservoir.Use an extending handle magnet to go thru the bar oil fill hole & retrieve it and reinsert it with same magnet. A 30 second job. I just did exactly what you did. got as far as the flywheel and realized what I had missed . DOH!!

I have a Husqvarna 44 chain saw,s/n 5031839 and need the stud that actually holds the chain var and cover on.Any help would be great.Just getting the year the saw was made would be helpful.Thanks in...

The stud never changed through production, it is part no. 501454301 should be available through your local dealer, or on the web, it can be fitted without splitting the crankcase, with some thin wall tubing and pulling through the oil filler hole.

How to seperate crake case

You need to give us a little more info so as to help you, the model and serial number of the machine, pro saws have a vertically split crankcase, where as semi pro medels have a horizontally split case, the vertically split case would need you to heat the case to expand it away from the bearings, there are special tools for certain models, i can advise more when i know the model.

Only will run when squirting gas in carburator.I have replaced carb plug air cleaner end fuel filter.Taken to repair shop,they say something internal.SO what?

Could be a massive air leak, possibly the crank seal has fallen out, or the cylinder base gasket has blown out, remove the flywheel and check the crank seal behind, remove the clutch, sprocket and oil pump and inspect the crank seal on this side,if they have fallen out, or are very wet, replace them, there are kits available to blank off the inlet and exhaust so as to put a pressure into the crankcase to quickly show where the leak is.

I have a husqvarna chainsaw 41(1994-05) is what the model number is showing the carb has been rebiult new gasgets it has fire but will not run can u help

The 41 was quite prone to blowing the crank seal on the flywheel side, remove the flywheel and check, at the same time check the flywheel key has not sheared, behind the carb fixing plate is a rubber induction tube, make sure this has not split, als check the impulse seal underneath the induction tube.

Model 141 husqvarna saw would cut off as soon as i hit the throdle now it will not start

For some reason its running too lean on the mixture, this may be due to a fuel blockage, or it just wants richening up on the mixture screws, start by replacing the fuel filter in the tank, check the fuel hose up to the carb for signs of leaking/cracks or splits, if the carb has standard screws to adjust the mixture, turn each one ( H and L ) out 1/2 turn ( anti clockwise ) on each, if it still does not run any better it may need a carb service. To remove the carb, first remove the two screws securung the air filter, then remove the two 10mm nuts securing the air filter back plate, remove the wire throttle rod, now remove the two cross head screws from the carb back plate into the crankcase, finaly remove the the two 7mm studs securing the carb, remove the fuel hose from the carb elbow ( use a suitable plug to stop fuel sqirting out of the hose a set of forseps works well ) with the carb off remove the single cross head screw in the alloy pump cover, here you will find a gasket and a pump diaphram in that order, there will also be a main fuel screen which will need cleaning or replacment, if the pump diaphram looks aged replace this importent component, now turn the carb over and remove the four screws securing the metering cover, here you will find the metering diaphram and a gasket in that order, replace the diaphram if it looks aged or the metal disc is bent, the metering lever controling the inlet needle should move easily and be set level with the sides of the carb body, if too low just bend it up, if too high bend it down, this is about as much as you can do with the carb without special tools. Whilst the carb is of check the induction rubber, to do this remove the two m4 allen screws holding the carb back plate on, pull the back plate up and out,behind here you will find the induction tube, make sure it has not split, below this tube is the impulse seal check this is seated correctly and not split.
Let us know how you are getting on.

Ive removed the cover on the crankcase side in order to change the chain itself. The cover is held in place by two studs. I cleaned the crankcase and then went to fit the chain assmebly and cover back on....

I really can't see the studs falling inside but it sure could drop out. But to make sure and satisfy your curiosity take your saw and shake it, or turn it upside down then right side up and listen for noise to see if it could be inside your saw. Sometimes when you remove the nuts the stud comes with it and you don't think too much of it. I have done that myself. I hope this helps, thanks.

How do I lock the flywheel to unscrew from the Crankshaft

I take the rewind cover off and use a large strap wrench like for plumbing to hold it in place, I've also wrapped the flywheel with webbed strap and clamped it in a vice. Don't hit the end of the crank with a hammer to get the flywheel off, purchase a flywheel puller, they are cheap and will avoid damaging the crank.

066 stihl, have all screws out but can't split case.

Assuming all screws are out, intake, exhaust and cylinder, oil pump and all oil pump related items are removed Screw the clutch carrier back on to the crankshaft (this protects the crank threads) and tap the crankshaft with a brass hammer. (TAP not Whack.) The tapping should loosen the 2 halve of the crankcase. You must replace the crankcase gasket.

Spltting a crankcase on a Husqvarna 394 chainsaw?

the gasket is what is holding it together, if all the bolts are off. you gotta peel it apart. put one side in a vice is how i do it. and do it slowly. everything should slide out .im just telling you from my memory and i cant visualize that particular engine at the moment.
