Today I fixed the cuts to my Stihl 066 Chain Tension Adjustment.
I can’t say I fixed the adjustment. I can say I covered up the holes in the adjustment which makes me feel better that it won’t fall apart as easily.
I mixed some JB Weld Steel Stick and slathered it on where the chain tension adjustment needed repair from being cut by the drive links of the chain.
The photograph at the top of this post shows the results of my chain tension adjustment repair. There would normally be the chain tension adjustment screw and cover plate in this photo. I removed them for the repair.
Here’s a photo of before the repair.
How things look now.
I won’t call today’s repair structural. I’m not even sure I should call it permanent. The repair gives me piece of mind that if the chain is ever thrown it won’t do more damage to the chain tension adjustment.
Last weekend I got to work on my Stihl 066 Chainsaw. I was nervous about what I’d find once I cleaned away all the saw dust. While the saw looks in great shape it shows signs of wear.
The plastic has scratches and the shroud near the muffler is burned. There’s also damage to the magnesium body of the saw.
Here’s where I am after a few hours of cleaning last weekend.
I took DonyBoy73’s advice and put the Sithl 066 Chainsaw shrouds in one box and engine parts in another. I put smaller parts and screws in zip lock baggies with labels because I don’t know how long the saw is going to be apart.
There was one small issue and one major issue with the Stihl 066 Chainsaw.
The small issue was broken magnesium near the oil fill hole. I took a file and smoothed out the rough edges. That’s all the attention the repair required.
The second issue gave me cause for concern. The frame of the saw underneath the chain tensioner was cut by the drive links of the chain.
I was very concerned about this damage because I don’t want to use a Stihl 066 chainsaw that may throw a chain. I visited my power equipment dealer and they told me not to worry. There’s plenty of metal left to keep the chain tensioner working without falling off.
I’ll fill in where the magnesium was worn away with JB weld. After talking to the dealer I’m not worried about structural strength.
There should be a chain catcher on the screw to the right of the plastic circle. It wasn’t on the chainsaw when I bought it. I purchased a new chain catcher and will install it before I use the saw.
Finally, I purchased new studs to hold the bar on. They were worn from use, or misuse, and should be replaced.
If I had seen the damage near the chain tension screw I’m not sure I would have have bought the saw.
Once I use the saw I’m sure I’ll realize the damage to the chain catcher isn’t a big deal. I plan on wearing my chaps and being extra careful the first few times I use the Stihl 066 chainsaw.
