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!

Re: 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.

Here is the diagram of the sprocket cover, ive had a similar problem in the past with the part ive highlighted,i seggest you dismantle it all and clean, replace any bent/broken bits and fit. They have a tendency to pack themselves with sawdust.
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.
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.
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
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.
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. ADW
I found an IPL for your saw here: HusqvarnaUSA.com http://www.husqvarna.com/us/homeowner/support/download-manuals/ 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
