Gathering chains
09 / 520
Gathering chains
Special slipping wheels (R) are to secure the gathering
chains and to prevent the penetration of foreign substances.
The position of the gathering chain drivers (A) to each other
is permanently changing, even on normal harvest operation
by response of the slipping function.
When stating a chain elongation (ill. N 107), there is the
unique chance of shortening the chain by one outer and inne
link plate each (B). The shortening to be made in the area
(14) = 14 pces. link pin distance from driver to driver.
The plastic protective rings (O) beneath the slipping wheels
to be checked for good state.
Chain tensioner
The maintenance-free gathering chains are automatically
tensioned via constant spring pressure.
The preset chain tension is also to regulate the driving torque
of the gathering chain and thus the efficiency of the slipping
wheels.
When to change the gathering chains?
= 83 mm chain in new state
= 113 mm chain worn-out, replacement required.
Attention!
Consider also the wear of the frontal reversing wheels!
Dismounting of the gathering chains
The chains can be dismounted with ease by using a special
tool, spare part no.
501190 attached to the header.
Prior to working on the machine,
Diesel engine to turn off.
Special tool may jump back!
The gathering chains are recommended to be
changed once the year from right to left and
viceversa to ensure thus a uniform wear.
Frontal chain reversion to dismount
Tool for chain dismounting to place to pos. (B) as shown in
ill. N 058 and N 198 and to pull tight. Lever to secure under
hook (E).
The frontal reversing chain wheels to be dismounted in the
same way. Special tool to mount into bore (L). Lever to
secure under hook (E), then the fastening beneath the
reversing wheel to remove and tool slowly and carefully to
relieve.
Tool jumps back by !
spring pressure
Risk of accident!
