Spltting a crankcase on a Husqvarna 394 chainsaw?

Does anybody have experience splitting open a crankcase on a Husqvarna 394 chainsaw? Head is off, all bolts removed. Not sure if I need a special tool for this? If anybody has advice please send it my way!

    This is how I split my crankcase apart. This tip came via an amish man. Lightly heat the area where the bearing is housed. Go in circles.Then use a rubber mallet to pound on crankshaft end. I did this 2-3 times and it came right off. repeat for other side.

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.

I have a 394 chainsaw wont stay running

The plastic sleeves are anti tamper devices, if you screw a small self taping screw into the centre of it, it will strike the screw under neath and drag the plastic sleeve out far enough to insert a 2mm screw driver through the hole in the centre and adjust the screw beneath.

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.

Revs up when pointed down slows down when pointed up without throttle on

A number of possibilites here, first are the anti vibration rubbers sound? if not the crankcase will move on the tank and engage the throttle prematurley, if the fuel hose is hunh up in the tank, or split this will lean the mixture and result in high tick over

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.

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.

Wanted coil ignition module for Husqvarna 394xp chainsaw

I found an IPL for your saw here:
Enter 394 as model number (no XPs, Es, just the numbers)
Serial number decode – for use with IPL
06 1500198
06 = year produced – 2006 (single digit before 2000)
15 = week produced - March
00198 = 198th unit Husky produced that week

I chose the 92-10. The coil and wire were manufactured as separate pieces. I found both at Jacks Small engines. It is interesting that the same ignition wire fits a Poulan at 1/2 the cost. About $86 for both pieces at Jacks. HTH
