044 project

Do any of you guys fit the heat shield between the jug and muffler on your hybrids?

I've just realised that there's one in the IPL I got, but mines not got one, and I'm damn sure that my initial saw, which was complete did not arrive which one fitted.

?

I would say you will get a load of cold air from the flywheel disappear through the rat hole rather than over and through the cylinder..

I don't want you mean Adam. Sorry have my programming head right now!

I think the shield is keep excess heat away from exhaust side of jug, rather than coming straight off the muff....

(I better get back for a few hours, but thx for yer comment)

Both of my 44's don't have the heat sheild. Guessing they started with the straight fin jugs or the 440?

I am guessing the shield does both, it is to stop heat from the muffler and to aid the routing of air from the flywheel fins over the cylinder. If it’s not there, there is a gap between the cylinder and the flywheel side of the casing that the air would just surge out of. The top cover should also shut off around the heat shield to keep the air flowing over the cylinder and out the PTO side rather that leaking under the cover and over the muffler. Without the highlighted part of the shield there is a massive gap for cold air to leak from..

Yeah, cheers Kyle. I'll check the manual later - I'm not sure I even saw it mentioned....

cheers Adam.

F**king nuts! Another part to buy. Hey Adam check your Inbox?

It may not be on yours like you said, but on every new saw there is one lol.. Can only help longevity.. Have done..

The heat shields were only used on the newer saws after they started closing up the mufflers. I removed the one on my 440 after I installed a vented muffler, no problems.

I would not worry about it unless you are running a chocked up muffler.

Why did you remove it, if it was already there? surely any extra heat shielding and air over the cylinder is a good thing?

 

[MustangMike]

My 044 never had one and runs very strong, so obviously there is no advantage to having one on a saw with a properly vented muffler. They only added them after they started chocking down the mufflers.

IMO, it was unnecessary weight. It was a solution to a problem that my saw no longer had. Plus, it is just much easier to install the muffler w/o it.

Deffo, the amount of times I have put a muffler on my 346's 372's etc and then found after popping the cover off that the heat shield is skew wiffy...

 

[BonScott46]

If you put it on the early 44's you will have to cut a bit of the cover. I have a shield sitting on the parts shelf, have not gotten around to it.

 

[BonScott46]

The 10mm I got shipped over from England had a baffled up muffler with a half inch outlet which I thought was pretty restrictive but still no shield.

I ordered one of these bloody shields like yesterday. I'll probably still fit it.

But I'm now wondering, what's the point of putting the gasket back in? The gasket is basically flattened anyways.......and surely the Stihl/Husk must make these shields flat enough in the first case.....as otherwise wouldn't they need a gasket on BOTH sides of the shield. Just my pedantic OCD mind wondering......

(If anyone wants a tip with holding it all -gaskets,mufflers inline - I use 2 thinnish screwdrivers through alll the holed items - right into muffler holes, then carefully remove one driver while threading up the first screw....but I'm sure you guys use similar techniques...)

I know it's not the same saw but the 372xp and most Husky shield gasket sequence is like this..

I dunno what to say.......except.....gaskets suck.

 

[Basher]

On 044`s, shield first against the cylinder, gasket next, it just helps seal the muffler to the shield, the muffler sealing area is seldom perfectly flat or true.

The easy way is to put a cushion (or card board) under the handle and stand the saw straight up. When vertical, the stuff does not shift.

Ha ha! Yeah I guess we all stand 'em up vertical......I like as much help as I can get, and try to hold 'em in line as well with the drivers. Especially if you've got to juggle the lower spacer as well on a hybrid!!
