MS660 fuel tank problems

[landrover 101]

Has anyone got a 660 they are breaking for bits I need the rear handle and fuel tank as mine has a not so nice crack across it after a mishap earlier today and fuel is leaking out everywhere

 

Or failing that has anyone any experience of the Huztl spares that are for sale on eBay - are they any good or are they junk as a complete tank and rear handle assembly from them is around half the price of the bare tank/handle from stihl

 

Guess I may have to try petro-patch first has any one used this on a plastic tank before as it says only suitable for metal but it may provide a short term repair

Can you post a picture of the crack? It may be weldable.

Will see if I can a decent pic in the morning

 

The crack has gone back together quite well but it runs from left to right across the saw just under where your knuckles would be when gripping the handle and is split across the 2 different plastics making up the handle and tank and straight through the seam where these 2 plastics join

 

I did contemplate getting the soldering iron out to see if I could melt it all back together but I don't think it would across the join

I don't reckon Petro Patch will work, plastic welding is probably the best bet, screwing and gluing on a thin metal patch may be an option. Of the sealents I have used, "Seal All" came up best for petrol leaks.

Might have try some seal all then

 

I have used petro-patch before and had good results but on metal tanks which is what it is recommended for wasn't sure if it may have been worth a try but will try and get some seal all in the morning

 

Then just need to be a little more careful in future

You could try with a soldering iron but you would need a pretty high temperature one - check the underside of the handle and you will probably find a code which runs PA6-GF8 which is nylon 6 with 8% glassfibre filling. It is weldable but best done with a hot air gun with a fine nozzle, and it takes 360degC to do it.

 

If you do decide to try to weld it, dry the inside of the tank, then get a hot air gun pointing at it, far enough away that it gets warm but not hot, and leave it running for about 4hrs (really). Nylon takes on water and it spits and won't weld unless you dry it out first. The other option is putting it in the oven on ultra-low but unless you have a big oven you will need to take it to bits first and you also need a rather tolerant wife/partner, or one who is going out for the evening.....

What about fibreglass. I repaired my auxiliary oil tank for milling and it has held ok. Bit of an overkill job and it sure doesn't look pretty but it does the job.

J B WELD thats the stuff i think is good for the petrol/oil engineeringy thingys lol have been told its good stuff i,ve bought some myself but never used it in anger yet but others have used it on petrol strimmer tanks and worked

[landrover 101]

Will give JB weld a google and see what it comes up with -

 

I think this will only be a temp fix for a month or 2 until a new tank and handle assembly arrives in the post just could do with a better inflow of cash at the moment than I have actually got
