Hi All,

I have recently purchased a 075 AV. This saw doesn't have a chain brake but I intend to fit one either through buying parts or a second hand one from a 051 or 076 or something.

however I'm confused as to what the differences are between the clutches in the two variants as you can see in the pictures, my saw has the one from the non chain brake image, do I need to swap this for the one in the chain brake version?

anyone have a good idea about where to get reasonable priced parts in Europe to do this?

and lastly don't suppose anyone is selling a chain brake for the aforementioned saw or a 051 or 076?

I've owned them with and without. The brake equipped covers are costly if/when you can find them. Maybe you can find someone who mills with this saw (and neither needs nor wants the brake in that application) to swap with?

I'm normally a fan of safety devices and use the brake on my regular saws religiously, but given the realistic uses for this saw platform and the relatively low chain speed this saw puts out, I felt OK going without. Your mileage and preferences may differ. I ran a 41"/105mm bar on my non-braked 075, and a 25"/64cm bar on my braked 076.
 
I think that lower clutch breakdown image is an isolating type clutch. In addition to the band braking the drum, another part of the mechanism disengages the crankshaft from the clutch allowing it to freewheel. I'd avoid this clutch like the plague.

An 076 brake cover assembly and hand guard matched up is what you need. Drum will be the same between an 075 and 076. I am unsure of the fitment of the hand guard to an 075 crankcase.

Far as chainbrakes on vintage saws, they are nice for originality and safety and they do add value for sure. Just check out what original Husky 2100 and Pioneer P-series brake parts bring in. That said, I don't think loggers could remove brake parts from these saws fast enough back when they were new.

Yeah I agree with you, I think it's going to be a case of keep an eye out for one as and when it come available at the right price.

It's also my first older saw I've bought as a project, any advice?

Thanks mate, looking at it that does fit. I'll be staying away from it for sure!

Cheers, I think I'm just going to have to keep an eye out for one and hope it comes up at the right price. I have a later 075 when I believe the brake was an optional extra so the crank case on the saw has the required mounts for it which the current hand guard is mounted too.

I'll have a look at the husky and pioneer parts , the most expensive parts for the 075 seem to be stuff like the exhaust cover and the exhaust itself, the previous owner has messed around with the muffler on my saw, he's enlarged the opening and done some sort of welding on the back of questionable quality. I intend to replace this at some point to try and keep the saw as original and unmolested as possible but I really do wish he'd messed with something else!
