Oil leak and clutch issues

[Matthew Jones]

Hi all,

 

I have 2 new chainsaw issues..

 

1. Continuing oil leak. The oil does not seem to be leaking from the bar and chain side of the saw but from around the casing and leaking in and around the flywheel. My question is, can the oil tank itself leak oil out of the actual case between perished seals etc? If so I'm happy to replace the tank but just wanted to check if this was an issue as it's an expensive part. I thoroughly checked all other places for oil leaking and it seems to be coming from the actual tank casing leaking in and around the flywheel.

 

2. After using the chainsaw for no longer than 5 minutes it gets really hot and is overheating around the clutch drum. The chain and bar are definitely getting lubricated so I'm thinking it's an issue with the clutch drum/assy itself.

 

Any help will be greatly appreciated.

 

Thanks in advance

Oh, the saw is a Husqy 440e

Check the brake band in the side case Matthew, it could be rubbing on clutch drum, oil leak 🤔 pic might help. K

The tank/crankcase is cast in two parts and friction welded together, if it’s leaking by the flywheel then the casings are no longer sealed together, is it definitely chain oil and not a leak between the cylinder base and tank/ crankcase, this may explain the heat due to an air leak and running lean

Thanks chaps, will check the brake band although I have just replaced this.

Hmm that's a good point. I think it's definitely chain oil although i'll double check this. The overheating is definitely coming from around the clutch as it's smoking from that point. Thanks for the thoughts guys, will have a tinker!
