What's on your bench today?

[spudulike]

Have been working on a MS150 today, both front engine mounts had spectacularly failed so the engine had to come out, the top end removed, the lower clam split and then the clam side with the damaged mounts supplied. The job is a mare, everything is sooooooo small, the bearings are conventional roller so the crank is held solid by the bearing unlike most small saws.

I had to fabricate a splitter plate to split the lower crankcase, the bottom end is a cross between a clam engine and a vertical split engine and none of my pullers helped that much.

The pics show the damage. The mounts are almost completely worn away - the screwdriver points at them.

The early warning sign is the kill switch stops working SO BEWARE!!!!

Not sure I follow that, the failure is the engine mount bolts coming loose, the earth point for the kill switch is on the top mount so that stops working. Arb types are clever so use the choke to kill the saw and the next step is the engine gets VERY loose. Sharpening the saw wouldn't help......making sure the mount bolts are tight as soon as the kill switch fails is sensible!

you didnt follow at all

 

the tiny chain on a 150 is a nightmare to sharpen unless you are 16 years old with 20/20 vision

Ah - you were telling me that sharpening the saws is a PITA, I read it that sharpening the saw would have stopped the engine mounts disintegrating....Doh

You should know by now, if engines are mentioned I butt out off the conversation

I've a mac 842 carb soaking in acetone trying to get all the chain oil out but im waiting for a carb kit for it.  the customer got the fuel and oil tanks mixed up and left the saw sitting for months with oil in the carb

I put a carb kit in my 036 today. It wouldn't tick over or run apart from flat out. I stripped the carb and it was full of oiled up dust, first time I had it apart and now it runs really nicely. The seized 044 I bought has a new piston and clutch, cleaned the cylinder up and it runs well. It has the 18" 036 bar on but I have a 20" coming for it then need to find some wood to try it on.

Small fix on the chipper. 

Great service from @arbrepservices (think that's their tag)

You back now mate?  I got to get that 150 back to you for sorting.
