How to proceed:
• Switch off the engine.
• Unfasten the large black cover plate (read § 11.4.12).
• Leave the tensioning roller to cool down before disassembling it.
• Unhook the tension spring that keeps the tension arm in a neutral position.
• Unfasten the starlock locking clip at the back of
the bolt. This will now have to be replaced also.
Stock code starlock BB 011 000 090
• Unfasten the fixing bolt (M8, size 13 spanner).
• The tensioning roller can be ordered from an authorised ELIET dealer under stock code
tensioning roller BA 599 005 300.
• Apply some extra lubricant to the bearing joints to avoid dirt penetrating around the new
tensioning roller.
• Remount all elements to their original position and securely tighten the tensioning roller.
• Hook the spring back on and verify that it is properly mounted. A loose spring can disrupt
control of the electrical height setting mechanism.
• Remount the black cover plate
11.4.6 Chain tightening
The machine has one chain drive: the chain that provides transmission from the first roller to the
rear roller as well as the drive of the rotating drum in the seed reservoir.
• Its capacity and RPM are very limited, hence the choice for a single (simplex) chain.
• This chain may turn forwards and backwards, depending on the direction in which the machine
is driving. A chain tensioner with a double function has been provided to accommodate this
feature.
Caution:
Never tighten the chain too tight. Too much driving capacity would be required
as a result, leading to extra wear of the chain and sprockets. Furthermore, a high
radial tension can harm the cap seals and bearings.
