Alltech KEENAN MechFiber340 - Chain Maintenance and Inspection; Checking Chain Tension Arms; Automatic Oiler Reservoir Check

Revision G04 July 2018
8. Maintenance
The KEENAN MechFiber Mixer Wagon has been designed for optimum perfor-
mance with a minimum of maintenance. Chains, bearings and grease points
have been kept to a minimum without compromising function. All components
are of high quality and provide excellent durability. Regular routine maintenance
will ensure your KEENAN MechFiber Mixer Wagon gives you the best results
with a minimum of problems.
WARNING:
Prior to carrying out any maintenance on the
machine, always ensure tractor engine is stopped
and disconnect the P.T.O. and hydraulic hoses
from the tractor. Observe safety precautions at all
times when working on machine, read Section 5
on safety before attempting to work on machine.
The recommended operating pressure in the hydraulic circuit is 170 bar and
a ow rate of 40 litres per min. Replacement hoses should comply with DIN
EN 853. When replacing hydraulic hoses, always wear suitable protective
equipment.
8.1 CHAINS
1. Each week check the condition of the chain tension arms and adjust as
required. There are two chains used on the KEENAN MechFiber model.
The primary drive chain (ASA120) drives the idler shaft and the auger shaft
from the input shaft (see gure 9) and the secondary chain (ASA160SH)
drives the rotor. Both chains are tensioned by spring assemblies on
the slack side of the chain.
Note: ASA120 chain uses split pins in the joiner link as
shown while the ASA160SH chain uses roll pins due to
the high loads involved.
2. Each day check the level of oil in the automatic
oiler reservoir (where tted). If the oil level is
low, top it up with light oil, grade SAE 10 or similar. The capacity of
the reservoir is 1.89 litres.
Note:
A: Do not use heavy/high viscosity oil, as the back pressure in the pipes may cause
them to be blown out.
B: Do not use grease on the chains, as it is unsuitable for the application
and will not allow lubrication of the vital internal parts of the chain.
C: The standard automatic chain oiler attachment gives a squirt of oil (approx. 15ml)
every time the guillotine door ram cycles. In this way, the machine is oiled in direct
proportion to the number of cycles and adequate lubrication is assured. There is an
adjustment screw on the base of the automatic oiler, turning clockwise applies less
oil and anticlockwise more.
