Husqvarna 345 Intake Replacement

[Onan18]

The site has been hurting for build threads lately, so I thought I would document what is a standard job for a dealer. We all know how failure prone the intake clamp is on the 340/345/350/351/353/346/357/359 and this is what it takes to replace one on the "junk" saws.






Partially disassembled and initial cleaning.


First step is to remove the clutch.

 

[Onan18]

These are so cheap it is really not worth trying to do the job without one.


Easy as one...

Two...

Three.

That saw is really clean. Did you just blow it off with air or what? If it weren’t for the rust on the muffler and some little stuff on the top handle, I might assume it looks new.

 

[Onan18]

Flywheel next, loosen the nut.


A little leverage...


A sharp tap with a persuader and it's off.


Make sure your ground strap is in good shape, and if you choose to remove the coil do not lose it.

Pressure Washer, does wonders.

Getting the carb off is easy, first, pop the retainer wire out of its catch.


Mash the trigger.


Hold the throttle shaft and release the trigger, pop the linkage out.


Remove the throttle rod and bellows.

 

[Onan18]

Drain the tank and remove the fuel line.


On the E versions disconnect the purge line.


Here is how the wires go.


Remove them.

 

[Onan18]

The air horn is held in with two vibration dampeners.


Release them.


Two 4mm screws.


Carb is out.

 

[Onan18]

Disconnect the Choke.


And apart.


I won't tell you what to do with these.


Carb kit is always a good idea.

 

[Onan18]

Muffler should come off with a 4mm Allen.


Sometimes more drastic measures are in order.


Five screws.


And the tank and handle will come off as an assembly.

 

[Onan18]

Cylinder screws come out from the bottom.


5mm Allen.


You don't have to, but pulling the flag makes life a lot easier.


Did I mention that you don't have to take the muffler off? LOL


See.

 

[Onan18]

Tasty.


Excuse me a minute.


That's better.


New intake kit.


Installed.

 

[Onan18]

Starting to go back together, I used Dirko because I was out of Hondabond HT, they both work well.


It is a Husky after all.


Screws in.


Flywheel on.


And tight.

 

[Onan18]

Typical.


I prefer the Echo vent anyways.


Tank on.

 

[Onan18]

Worm gear in.


A little grease on the bearing.


On.


Clutch and drum on and tightened.

 

[Onan18]

Flag is held on with shouldered screws.


The detent goes in a notch in the flag.


Like so.


Air deflector on and wires routed.


Starter on, if your rope is questionable replace it now.

 

[Onan18]

Starting to look like a saw again.


Gee, look what happened.


New kit.

 

[Onan18]

Gasket goes on first.


Then the diaphragm.


Other way around on this side.


Like so.


Air horn back on, don't forget to hook up the choke, doh!

 

[Onan18]

Slide everything in at an angle and get the screws started.


Pop the dampeners back in.


Tighten the screws, hook up the wires and purge lines.


Throttle rod next.


And the fuel line.

 

[Onan18]

Clean and reinstall or replace your air filter, new plug is always a good idea.


Top cover.


Bar and Chain, clutch cover, fuel up, and off to the races.

I hope this helps somebody out.
