Take regular screw drivers and pound them in a little with a hammer and then pry all the way around till it comes apart.

Hi Remove the spark plug,fan housing and chain cover.Enter in the spark plug hole a piston blockator (a rope with many nods) and block the piston in the cilinder.Remove the clutch clockwise and the flyweel counter clockwise.Remove the air filter,the cover,the mufller,the carburator,the handle,the gas and oil tanks.Locate the 4 screews to remove the cilinder .Remove the oiler and the worm gear.At the clutch side are the screws to separate the crankcase.

I HAVE A RANMCHER 455 HUSQVARNA IT DOESN'T SEEM TO HAVE ANY COMKPRESSION


You stated that you checked the compression, How many pulls on the starter to get 50 PSI?
Also some shops check compression, way to quickly like pulling on the cord one time and then saying yup, No compression. There are a number of other things that it could be, like maybe the de-compression valve is not working or you have a crankcase seal leak.
Anyhow, If you put the correct fuel and oil mixture in the engine, I seriously doubt that there is anything major wrong with your saw

Hto remove crankshaft seals on a husqvarna 136 chainsaw


You will fully disassemble the engine as you must the cylinder from the crankcase. Husqvarna only sells the seals with the bearings they must be pressed on to the bearings. Since the 136 uses the same bearing set as the 141 you can order a set seals for the 141. In this the old seals must be pressed off first.
Here is a link to a site that sales the 141 seals.

How do I know if my husqvarna '51' has a 44 or 45 mm piston..Does it matter if I need a cylinder kit too...


The 50 had a 44mm piston, all 50 specials and 51s had a 45 mm piston, as a cylinder and piston both will fit the crankcase, the stroke was the same on both.

Inherited an older husqvarna chainsaw 50 rancher. Going through it see the start switch has only the wire from the ignition module going to the terminal on the switch...no other connection. Is the other...


If it is an early 50 the sides of the switch are metal, so this creates the earth, the later machine has a plastic switch, this had an earth tag on the switch, which sat on the top of the crankcase and was secured with a self tapping screw, this also held the switch in.

Hi. Is it possible to drill & tap the raised round boss on the crankcase casting of a Husqvarna 272xp chainsaw & fit a decompressor. I really struggle to overcome the compression to start this saw....


Absoulutly not, this will end in disaster, try fitting an additional cylinder base gasket, and move the ignition module out to 0.5mm, make sure you are useing a 50-1 fuel oil mixture, i have done this many times and it will make things better, good luck.
