Oil reservoir repair

Recommended Posts

Hi,

 

I'm after a bit of advice regarding a repair...

 

A bolt holding the exhaust on my saw (Hitachi CS33EB) sheared off recently and the red-hot exhaust slipped down and melted into the plastic engine case, resulting in a hole in the oil reservoir.

 

I've tried to repair it with fibreglass, but used the saw today for the first time and there is smoke/smouldering coming from the repaired area. There is only a small amount of clearance between the exhaust and the case, so I don't think the repair can take the heat that's coming from the exhaust.

 

Any suggestions as to what I could use for the repair of the plastic case which could withstand the heat from the exhaust?

 

Hope you can help,

 

Matt

NEW CarGo QUICKSTEEL STEEL REINFORCED EPOXY PUTTY REPAIR METAL WELD - 2oz on eBay!

 

Try this, its great stuff, ive fixed alsorts with it, you need to take your time and get it right tho.

 

+1 super stuff, much easier to use and sets much harder than JB Weld or araldite. no messy mixing: just slice a bit off, knead it and fix it

Buying a new engine case is an option, but I've not been able to source one in the UK. Also, they're around $40 in the US, so may be £30+ over here.

 

A picture of the damage is attached. The hole is around 2" long.

 

I've ordered a tube of Quicksteel from Amazon, so will give that a try.

 

Thanks very much for your help,

 

Matt
