When the wife is away.....

I noticed that you have an electric oven, they get hotter and heat more evenly than a gas oven, so I'm not surprized. The bearings need to be at the bottom of the bearing cup with the outer race against the cup shoulder. Puting the bearings on the crank will leave them out of contact with the bearing cup shoulder and make it much easier to spin a bearing, which will ruin the case in most instances.

The last time I was at HVA in Sweden I watched two female workers standing at the end of the paint curing oven with a freezer full of bearings, they would flip the case over so the gasket surface was up and drop in the appropriate bearing. I don't know for sure but I'll bet the paint cure over was at 200°C!

 

Dang Brian I missed the most important thread on the site..... congrats my friend!

My wife and I find out what we'll be having next this thursday.

 

Bryan did you run the 7900 today or sell it to Dexter? LOL!

 

Hahaha I did get to run it and Dex isnt getting his mitts on it anytime soon. He, joshmain and myself (plus the boys) had a nice time running the 70cc saws.

The 7900 runs really well and just feels nice.

I picked up my 346 on the way and ran it in the 12x12. It really held its own. Eric builds a nice saw.

 

That messing about with a hot case is bad enough with the bearings, let alone trying to get the crank in both sides and keep the gasket where it is supposed to be. Buy the tool, you won't have burnt fingers when you are done. Lincoln welding gloves are also a big help, my wife uses them for oven mitts!

 

Wait a few tanks till she breaks in, then you will get the full effect! They are very nimble for an 80cc saw! I am so glad that you are pleased!

And Master Mech put up your video.

 

A minty 056 mag would be cool....but I have enough saws already Dex. Thanks again.

 

As stated earlier, not every saw on the planet benefits from a MM. The 7900 is one of them. Take out the screen and open up the factory outlet a little and put the screen back! It is very easy to mistake 'loud' for better performance.

 

When the wife is away does the dishwasher become a parts washer?

 

A while back I tried to pull that dishwasher trick with my wife, it didn't work. 1. She was pizzed as all get out 2. The dishwasher detergent changed the color of the bare aluminum parts. She stormed out of the house and jumped in her truck and took off.

Returned about 45 minutes later with a new 20 gallon parts washer in the truck "the oven is one thing but my dishwasher is off limits" was her only comment.

 

Stihl recommends putting a little Dirko or 1194 around the outer surface of the sealing ring where it meets the case prior to installation. I have started doing the same thing with HVA saws I restore. Do yourselves the favor of getting the factory seal puller be it Stihl or HVA, that drywall screw method can cause big problems bu maring the sealing ring surface in the case.
