Oil reservoir repair

[mattel]

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

Can you not get a new tank???

 

Might save a few quid. Not familiar with the saw so don't know the setup of tank to exhaust.

I'd try sticking a patch on with araldite, used it on an 020 tank once, lasted well.

How big and what shape is the hole.

+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

I`ve used that quicksteel, as linked above, and had good results as well. Just a note, make sure the surface is clean and oil free before using, a bit of carb cleaner should do the trick.

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,

Clean it well as said all ready. Push the filler right through in to tank and dome it off, but tank will need to be clean as well.
