390xp muffler mount bolt

[Colonel 428]

So the new to me 390xp is missing one of the smaller muffler brace bolts that hold it to the muffler. Anyone know a husqvarna part # for it? Thanks.

For most saws, you can Google the model number followed by IPL and will get some sort of parts breakdown

I typed in “390xp ipl”. #7 holds the bracket to the muffler, #6 holds the bracket to the case, #4 holds the muffler to the cylinder

Pics weren’t very clear. These are better

Thanks Kevin. Kinda hoped and expected to hear from you . I should have just said, "Hey Kevin, can you tell me what bolt this?" But I didn't want to be rude or pushy...

What source do you use to order stuff like that bolt?

I have a few spares that I have removed from junk saws. If they don’t have the flange on the head, I have used Allen head screws from the hardware store

Thanks again. I'll take the one that's still attached out and see if I can find a match locally.

If it’s the one that goes through the bracket into the muffler, they should be m5 x 10 or 12MM or so. Any hardware will have one. The screws that hold the bracket to the case are slightly longer. Maybe 16MM

Thanks man, I appreciate the help. of topic...What's a feeler gauge for measuring raker height?

 

[Colonel 428]

Off topic, sorry

 

[Colonel 428]

Looked it up. Got it and the concept of a straight edge and feeler gauges to set raker height.

They are used for lots of things. Anytime you need to measure a small gap. For measuring rakers, straight edge from tooth to tooth and slide the appropriate feeler gauge underneath to see how big of a gap you have. On a new chain you want about. 025“. On a nearly worn out chain you want about .035 “ gap

Got it. Any particular set or range of sizes best for rakers? Or is a set of 32 on a fan design good?

 

[Colonel 428]

Thanks Kevin. I actually learned something from you tonight that will definitely help me as I sharpen chains. I've kinda been guessing and sometimes I don't guess so good . Sucks to try to cut with a chain that is grabby to the point it bogs a big saw.

Most of them range from .0015“ up to .035. Anything like that will work well for rakers

Thanks again Kevin. Have a great night...
