[predator]

rite read your posts i,am going to get something to eat been out all day splitting logs etc ive been and picked it up and will get some pictures up etc then with the help from you boys i can sorce a bar sprocket chain etc

I think the challenge is going to be identifying which, if any, of the currently available sprockets will fit.

Oregon do a book that lists saw manufacturer, model, chain options and what order numbers they are

They do, and it's also available as an online selection tool, but it only goes back so far (unless the book version goes back further?)

 

Otherwise there are several ways I can think of to do this.

 

The easiest would be to contact the people in Somerset referred to earlier. It's possible they know the answer!

 

It would be worth dropping Magnus a PM as he may well know the answer, and if not it is likely that he will know a man who can.

 

Gordon at Carlton Trading may well have original parts and if not he may well know the modern equivalent.

 

As a last resort, measure everything up - for the bar you will need to measure the following:

 

Diameter of studs

Spacing of studs (centre to centre)

Distance from back stud to clutch drum

Diameter of tensioning pin

Vertical distance down from centreline between studs to the centre of the tensioning pin

Horizontal range of travel of the tensioning pin, although this can probably be guessed at from the photos

 

For the sprocket you will need to take it off and measure:

 

OD of clutch drum

ID of clutch drum

Depth of clutch drum

Diameter of crankshaft where it passes through the bearing

Diameter of bore through the sprocket

Depth of sprocket

 

There will be some flexibility around the above, and some degree of bodgery may be possible, but starting from that it should be possible to measure up a few existing ones and see what's available.

just been on oregon site no bars or sprockets

OREGON®: Selector Guide so unsure about the chain aswell till i,ve sorted a decent bar/sprocket

it looks like i may have to modify a bar to suit thats not a problem to me but the sprocket chain matching going to be a pain me thinks

[shavey]

i will have a look tomorrow and i will speak to the man in somerset and he might have a bar lying around he done a chain and service earlier this year
