The type 3080 Rollomatic bar for harvesters is now   Bar                      Bar
produced in a version with a groove width of 2.0     version                  length

mm (0.079") to complement the existing version       Part No.                 cm (in)
with a groove width of 1.6 mm (0.063").
                                                     3080 000 9923            64 (25)
This means that STIHL guide bars with a groove       3080 000 9931            75 (30)

width of 2.0 mm (0.079") are now available in
lengths of 64 and 75 cm (25 and 30 in) for

harvesters which accept type 3080 guide bars.

As the rail width remains unchanged, the thickness
of the new bar has increased 0.4 mm (0.016") to

6.2 mm (0.24"). This has resulted in a 22%
increase in flexural stiffness.
All other product features are the same as those

of the type 3080 guide bar with a groove width of
1.6 mm (0.063") (see TI 42.92).

When used together with 40 RMH saw chain
(type 3996), with a drive link gauge of 2.0 mm
(0.079"), this guide bar offers the user an
extremely high-strength, heavy-duty cutting
attachment designed for tough professional
applications on high-powered machines.

4. Service note

As the guide bar is 0.4 mm (0.016") wider, the
individual parts (adapter and countersunk rivets)                                  2,0 mm
have been modified accordingly. The nose

sprocket is 2.0 mm (0.079") thick to match the
bar groove width.                                                        8,7 mm
