Husqvarna 3120xp problems

[smithers1603]

Hi

 

Does anybody know if there is a special tool for tightening the exhaust bolts on the husqvarna 3120xp. Both of ours have both gone down with the same problem in the last couple of weeks. First one was put on the bench by a member of staff saying the baffles had gone, after taking a look both exhaust bolts where missing, also after checking the threads in the head they where gone so I've had to helicoil them. New bolts have come but I can't get anything inside the exhaust holes to tighten them.

 

Any help would me much appreciated

 

Regards Steve

If I am reading parts list correctly, no threads in cylinder the nuts are on the front of the exhaust

The real early ones had threaded holes either side of the exhaust port rather than the square retaining bolts. Not sure what the OP means about the rest though??

Early 3120 had long bolts with squared ends that slipped into cut a ways in the cylinder, the later cylinder has 6mm threaded holes and was from the k1260, the screws should be allen screws to enable tightening them.

Aw damn, wrong way round again, it was bad enough trying to screw the sparkplug in porcelain first

Thanks for the replies, I was scratching my head looking at the square heads on the bolts, I can see the difference now. I will re order the correct ones now [emoji106]
