Husqvarna 357 rebuild

[spudulike]

Made my "factory tool" from an old pallet, it worked, just need to think about these things.

Finally made some progress on it today. Stripped the complete saw down, put the case halves in the sink with plenty of hot water and fairy liquid to soak and they cleaned up well.

 

Pressed the good crank out of the donor case and had a few issues with one bearing sticking to the crank. Should have waited to get a small puller but muddled through. Gave it a good clean up, washed the big end out with petrol, blew it out with the air line and put plenty of two stroke oil in it before fitting it.

 

The new bearings dropped in quite easily with the use of the heat gun to expand the cases, and the crankshaft pulled into the bearings quite smoothly. I've loctited the bolts holding the crankcase together and wound them in nice and tight.

 

I used a GTS crankcase gasket, and wasn't especially impressed with the fit. Next time I'll go genuine. I've fitted a new fuel line and filter to the tank and then called it a day. I think I'm going to fit the crankcase to the tank, then carb plate, then piston and carb as it seems an easier way to thread the fuel and vent pipes through.

Don’t forget to give the clutch and flywheel crank ends a couple of wraps with a copper malet whilst it’s still stripped !

[spudulike]

Yup, de-stress those bearings or they will fry!

[Toad]

Oops! I spun it over by hand once it was all together and it was nice and free so didn't bother. I may come to regret that!

I think that one is heading for the bin! My father has been collecting random things and stripping all the non ferrous metals out of them to scrap. Sadly I think he's making about 50p per hour at this rate.

So, finished reconstruction today. Had about ten minutes of looking for where I hid the coil bolts from myself, and the clip for the intake boot is a total bastard to do up, I assume with some shaped pliers it would be fairly easy though.

 

Fired it up with a new bar and chain on, and let it clear all the excess oil I'd used for lubricating the bearings and piston. It started and restarted nice and easily.

 

I didn't do much to the carb on it apart from check the gauze filter was clear, and left the settings it arrived with on the carb when I took it to have a bit of a test with some bits of wood on my pile. 

 

The saw went really well in my opinion, was surprised how quickly it nibbled through some admittedly past it's best beech, but the idle was staying a little bit high at the end of cuts and slowly dropping back down. I had a check with my taxi and found the idle was a little bit high at over 3000rpm, so I backed the idle speed screw out a bit which settled it. Max rpm was around 13900, which is a bit fast, but I found the H jet to be against the limiter - it's the not fully adjustable epa carb on this one. - so I couldn't bring it down. I'm tempted to remove the limiters and see if that let's me slow it a bit, or if there is another issue. I did try adjusting the L jet but it became very boggy if I increased that one.

 

Now going to have a little panic that the issue is that I didn't distress the bearings and they've cooked themselves and the seals and that's why it's running fast. I'm sure it'll only play on my mind for a few weeks. ?‍♂️
