070 part

[agg221]

I'm confused! Has the grey metal tube that connects to the flywheel broke? Or has the little metal ring inside been stripped? The ring is an easy fix and still readily available!

 

On the early ones the ring inside is nylon rather than the corrugated metal type. This is nla, although you could probably make one out of a bit of nylon rod easily enough if you had to.

 

The connection to the flywheel is through three lugs at the back which can sheer off. These can be rebuilt if necessary.

It was the aluminium cup itself that was damaged, not the steel ring. Has now been repaired and all running nicely again.

 

Glad to hear there are plenty of others still making good use of these saws!

Haha, I bought mine in a well used state and rebuilt it, they are fantastic saws and designed to be repaired cheaply/easily

Hi guys i have recently dug out an 070 i would like to get going again . I have found there are a few places on ebay for parts . But do any of you know where i may be able to sorce just the fly wheel side of the crank case?

 

The origonal has broke where one bolt for the pull caseing ataches and where the front handle attaches i dont see the origonal beeing repairable. Dose any one think it could be repaired? Have found a whole crank case on ebay but seller will only sell as full caseing and fule tank

These saws were made in a way where two crank halves from separate saws could not go together, each casing is hand drilled and specific to the saw, on the other hand, the hole could be filled with chemical metal and shaped

That particular point is a common weakness.

 

If you want to do a useable job it can be rivetted (one of mine was repaired this way when I got it.

 

If you want a good job done it can be rebuilt in weld and dressed off neatly.

You can get aluminium brazing rod to build up broken parts using copper backing plates. We once attached a fairing bracket to a Suzuki frame using it and it stayed on for the life of the bike till it was sold.

Thank you for the reply guys didnt realise they where drilled buy hand . What are the chances of the head fitting well on an reproduction crank caseing can sorce one for about 80 od quid of the ebay

 

i like the idea keepin the saw as origonal as poss as its only gonna be a toy

 

The old man had it runing some 15 year ago

 

Braseing seems a good idea but wats left is a bit oxidised would thiss afect the the bond

 

Thanks

Yes, you need to get the surface clean. Grinding off with a small dremel, or heavy wire brushing will do a good enough job. You will also need to take the paint back from the break as aluminium is a good conductor of heat so the paint will otherwise burn off. Some people reckon a good inch but on old Stihl parts I have got away with around 3/8".

Chears if i need to make up a bolt hole for the pull casette would you recoment braseing on a pice of alloy or building up anuff to make a fixing point
