Husqvarna 137

[D. Akins]

I picked up a used 137. Saw is in great shape. Seller said it would cut then chain would just lock up after a while of cutting. I just put fuel
Line and filter, dressed the bar, filed chain, carb was clean. clean looking little saw that doesn’t appear to have much time on it. Engine fires right up and runs good. I noticed the bar plate is missing, I’m gonna guess this to be part if not all of the issue.
Oiler is working.

1. Do you think the missing bar plate was letting the bar and chain overheat and seize?

2. how much play is acceptable on the clutch drum? Seems like it has quite a bit.

So I was cleaning a little on this saw , I think the clutch has been hot. If you can, notice the melted plastic behind this metal band. I think that needle bearing is worn , drum is pretty sloppy.

And, looks like a hole is wore through the oil pump housing. Guessing previous owner ran the chain so dull it wore the bar and sprocket, bearing and I guess the chain got over in the oil pump housing.

suspected cause of damage is,
. Bar plate missing
. Bar mount plate missing
. Oil seal for that mount
. Oil pump had hole wore in housing
. clutch drum bearing seems sloppy
I measured pto shaft where clutch bearings rides, 10mm across the whole surface. Hoping the needle bearings wore and not the shaft.


whoever put this one back together didn’t have a clue.
