INTRODUCTION
This manual shows how to maintain the Series 5TM high impact tank cleaning machine from
Lechler.
Due to varying operating conditions that components are subjected to, we recommend
performing a maintenance in two steps: (1) Minor maintenance after 500 operating hours
(Maintenance 1), and (2) Major maintenance after 1000 operating hours (Maintenance 2).
Note: Maintenance 2 is a comprehensive service that also includes all steps included in
Maintenance 1.
A visual inspection must always be carried out at each maintenance interval of the parts for
wear. Under correspondingly harsh operating conditions the time to maintenance should be
reduced.
Recommended maintenance intervals
Operating hours Scope of maintenance
500 Maintenance 1
1000 Maintenance 2
1500 Maintenance 1
2000 Maintenance 2
Only use original Lechler parts for maintenance. All cylinder and hexagon head screws are se-
cured with thread lock lacquer. For use in the food industry we recommend LOCTITE

DISASSEMBLY
During maintenance, a visual inspection of all parts should always be carried out.
The components that require special attention are described in the following steps.
The following tools are required for maintenance::
Allen wrench with ball head 4 mm
Hexagon socket wrench insert (8 mm)
Round rod (brass or plastic) approx. Ø 4.0 mm
Rubber mallet
Allen wrench 2 mm (maintenance 2)
Open-end wrench (flats 19) Nozzles (maintenance 2)
Open-end wrench (flats 10), alternatively a flat nose pliers, width <4.5 mm (maintenance 2)
Vise with protective jaws (maintenance 2)
Face wrench (pin Ø 5.0 mm) (maintenance 2)
Info disassembly
All cylinder and hexagon head screws are coated with thread lock lacquer which makes it
dicult to loosen the screws. Since we recommend to replace all parts included in the main-
tenance package, the dismantled maintenance parts (including Cylinder Head Screws and
Hexagon Head Screws) can be put aside and disposed of later.
Remove the cover 5TM.000.1Y.33.C0.0
pos. 35 with the four hexagonal screws
wrench size 8 (SW 8). The cover may
stick due to screw locking lacquer on the
nozzle body. In this case, gently tap on
the side of the cover with a rubber mallet
to break the bond.
Cover Pos. 35

14
Loosen the four cylinder head screws and remove the cover 5TC.000.1Y.31.00.0 (item 34).
Cover Pos. 34
Information on bearing (pos. 32) on the shaft (pos. 9)
To loosen the screw that fixes the bearing 5TM.000.T7.29.C0.0 (item 32) to the shaft (item 9),
it is necessary to lock the impeller 5TC.000.1Y.05.00.0 (pos. 7) to prevent rotation.
For the size 5TM.410.XX.XX.XX.X, instead of the guide wheel 5TC.000.1Y.03.00.0 (pos. 3) a
ring 5TC.000.1Y.03.R0.0 (pos. 3) is installed. To prevent rotation of the impeller, it is recom-
mended to disassemble the connection piece according to your model.
Pos. Product name Product number Picture
3 Guide wheel 5TC.000.1Y.03.00.0
3 Ring 5TC.000.1Y.03.R0.0
(nur bei 5TM.410.)
For all other sizes, the impeller can also be locked even with the assembled connection piece.
Note: When carrying out maintenance 2, the connection piece must be removed in
any case.

15
Remove guide wheel. For the power size 5TA.410 the ring can be removed. However, this
is not absolutely necessary.
Unscrew cylinder head screws ( 5TC.000.1C.02.FS.0 / if necessary 5TC.000.1C.02.FR.0 )
and remove the connection piece.
Connection piece
For the 5TM there are dierent connection pieces (female thread, male thread, flange
connection- see pos. 1 spare parts list).
All connection pieces can be loosened with a 4 mm allen wrench. Depending on the type of
connection, a hexagon socket wrench with ball head may be required.

16
Size 5TM.2XX and 5TM.40X:
From the connection side push a rod
made of brass or plastic (diameter approx.
Ø 4.0 mm) through the guide wheel into
the impeller, thereby the impeller is locked.
Size 5TM.410.XX.XX.XX.X:
With the connection piece removed, insert
a rod made of brass or plastic (diameter
approx. Ø 4.0 mm) into the impeller, there-
by the impeller is locked.
Bearing pos. 32 – for shaft pos. 9
Now it is possible to loosen the cylinder head screw which is located in the shaft
5TC.000.1Y.11.00.0 (Pos.9) on the side of the bearing. Remove screw, washer and
bearing.

17
Note: Inspection of the worm gear during maintenance 1
During maintenance 1, the worm gear should be checked for wear. This can be done by a
visual inspection. In case of premature wear, caused by harsh operating conditions, the shaft
pos. 9 should also be inspected.
The following further steps are necessary for this:
Impeller Page 68
Gear frame Page 69 – 70
Shaft pos. 9 Page 70 – 71
If the shaft pos. 9 also shows heavy wear, it is recommended to perform maintenance 2.
new worn

18
Loosen hexagon socket screw and
remove together with the washer.
Impeller
To loosen the screw that fixes the impeller 5TC.000.1Y.05.00.0 (item 7) it is necessary to lock
the impeller with a round rod (e.g. made of brass or a plastic).
Lock impeller
Remove impeller

19
Remove the four cylinder head screws of the gear unit frame.
Attention! The screw with visible washer must not be removed.
Then the gear frame can be removed.
Hint:
It is possible that the impeller can not easily
detached from the shaft. In this case the
cylinder head screw (without washer) can
be screwed in for approx. 3 rotations in the
shaft. By striking on the head of the screw
gently with a rubber mallet, the impeller can
be detached from the shaft.
Gear frame

Hint: Before removing the gear frame, press the shaft towards the connection side.
Shaft pos. 9
Remove the shaft upwards.
