What's on your bench today?

[spudulike]

Well that was a waste of time.

 

I must learn not to go out on a Saturday night and rush a quick job in.

 

Ts400 pot and piston turned up today so after doing all the family stuff today thought I would just go and pop it on.

 

All went well fitting, no problems there. The saw started really well, run for a minute then stopped dead, pulled it over and could hear the fatal sound of ting ting ting, great.

 

Took exhaust off, rings are fine. Looked into plug hole and could see pitting. So then the swearing started.

 

Took it apart again and yanked to pot off, the piston was badly scored on the transfer port side, only one side, the score goes from the top ridge of the piston right through to the bottom. The intake skirt is also scored.

 

The scoring on the transfer side of the piston is not consistent with a snagged ring, as it goes through the rings, and the amount of bits on the top of the piston that fell out where too much for a bit of ring and piston.

 

So after checking my parts left over in the tray there was a gudgeon clip missing, so this must have been in the crank case on refitting. And got sent up the ports.

 

This saw was given to me so there is nothing lost by a customer, but if it was there is no change in procedure, another pot and piston to order, just have to take the hit.

 

Lesson very badly learnt, never ever ever go and rush a quick job in, I can't believe I didn't check the left over parts tray before I started the saw, its lesson 101 for crying out loud....

 

So let the slating begin, go on I know I deserve it.....

 

I always put a bit of paper cloth down between the crank lobes and spin it round to clear any debris and puddled fuel/oil from the bottom of the crankcase before re-assembly - not a nice result but glad it wasn't a customers!

I did that. Even turned it upside down. Must have been stuck in there somehow. Gave up and went home. Next time its a good flood out with petrol and a good blast from the airline.

 

Just one of those moments that I really should have left it until Monday......

Lucky it didn't take out the rod, at least it is repairable!

True. I'm not going to replace with another genuine pot tho. Can't take that big a hit on something that is not a customers.

 

And the machine is just too handy to sell on to be honest. One of those tools that once you have it it comes in really handy.

 

But now I'm starting to sweat as I have a makita cut off saw to do aswell.

 

That one I REALLY can't afford to do it again.:laugh1:

 

Making myself all nervous about them.

Where do you guys get your spares from for your repairs i always have trouble sourcing the items i need which delays getting my kit back up and running!

[wisecobandit]

Dare I say it Rich weve all been there and done something silly.

 

I put a new top end on a saw a few weeks ago in a bit of rush then just as I was about to pull it over I had one of those moments.... I couldn't remember doing the rings or whether I checked to make sure they where the right way up! , pondering I thought well I doubt if the piston would've went in the cylinder but I still ended up restripping the topend just to double check only to find them both fitted correctly.

Luckily that was just a time thing not damage.

I did up a Stihl 032AV some time ago and it sold on Ebay, it came back in last week with no spark! The local agent said it needed a new coil, now obsolete so was scrap.

 

The owner got in touch and asked for help - first thought was the coils are normally robust and it may be the contact breaker.

 

On removing the flywheel, the breaker was open circuit when closed - after a clean up - now closed circuit. Gave the flywheel and breaker area a good clean up, replaced the HT lead and cap that now had a big split in it.

 

Bingo - spark now nice and fat - saw fired second pull - all good:thumbup:

So much for Stihl backup/dealer/agent. Perhaps more interested in flogging a a new machine, than even looking it over properly. Good news for owner, is that it lives on.

The owner is a happy man and he should be for the work I have done and the small price I am charging, got to be fair though as it was one I sold him - fault showed up a few months later but should be all good now:thumbup:

[burrell_]

now that's why we should all take are stuff back to a stihl dealer

SO THEY CAN SELL U A NEW PRODUCT :sneaky2:

rather than fix the one u have

i no not all dealers are like this i think a big % are

 

good service again spud was it the nice 032 u had
