Assembly Instructions
Examples of general measurements for identifying assembly accessories according to
type.
To make it easier to identify the assembly accessories (nuts, bolts, washers, pins, etc.)
on the basis of the general dimensions and the type, we provide a diagram that shows
you the accessory parts to which the measurements refer as given in the various steps
of assembly.
The drawings are schematic and do not always faithfully reproduce the accessories,
but they will be of help in identifying them correctly.
Note: the accurate measurements are those given in mm; those given in inches are
rounded off, and for threads the size in inches is given only as an aid, as it does not
accurately describe the thread.
You can see the following examples:
Box “A”: shows springs that are will be identified by the wire diameter, the outside
diameter and the length, thus in this case ø3-ø18x110 (ø0.12”-ø0.71”x4.33”)
Box “B”: shows handles, spring pins, split pins, etc. that will be identified by the
diameter of the shank and the length, thus in this case ø8 x 50 (ø0.12” x 1.97”)
Box “C”: shows shims, bushings, spacers and washers in general that will be
identified by the inside diameter, the outside diameter and the length and/or the
thickness (for washers), thus in this case ø18-ø35 x 30 (ø0.71”-ø1.38” x 1.18”) or for
washers ø18-ø35 x 3 (ø0.71”-ø1.38” x 0.12”).
Box “D”: shows retaining rings for internal housings/bores that will be identified by
the diameter of the bore preceded by an I, thus in this case I35-1.38”, and for external
shafts that will be identified by the diameter of the pin preceded by an E, thus in this
case E35-1.38”.
Box “E”: shows pins, bolts, etc. that will be identified by the outside diameter (thread
diameter for bolts) and the length, thus in this case ø20 x 70 (ø0.78” x 2.76”) or for
bolts M20 x 70 (0.78” x 2.76”).
Box “F”: shows nuts and grease nipples that will be identified by the thread diameter,
thus in this case M10 (0.39”).
Box “G”: shows R-clips that will be identified by the diameter of the shank, thus in
this case ø3 (ø0.12”).

For tightening torques, see the table below (the class of the material is normally
stamped on the head of the bolts).

General assembly instructions for all models in the MK series.
As regards the indicating of
right/left, they are understood to be
attributed observing the machine
from point A (behind the machine)
looking forward.
The machine must be assembled in a suitable area, done by qualified personnel
equipped with the proper clothing, protective equipment and tools necessary for the
job. Only authorized persons should be in the assembly area.
Assembly is correct when the various RH sections A, C, E, etc. and the various LH
sections B, D, F, etc. are aligned and parallel to each other and when the coupling
flanges G between one section and another are flush. NOTE: since these are sections
to be joined by means of welded flanges, there will not be perfect linearity between
RH sections A, C, E, etc. and LH sections B, D, F, thus a certain margin of error
must be tolerated. To reduce this error to a minimum, a few small techniques must
be used. For example, tighten the flange coupling bolts, one outside 1 and one inside
2, if the RH sections A, C, E, etc. and LH sections B, D, F, etc. are linear; or tighten
first the outside bolts 3-4 if the sections tend to curve toward the inside of the
machine, and vice versa tighten first the inside bolts 5-6 if the sections tend to curve
toward the outside.
The alignment of the sections is important, as it also affects the assembly of the rake
wheel lifting pipes and how they slide along supports H during use. Bearing in mind
this advice, you can proceed with the assembly following the steps illustrated in
following. Unless otherwise specified, the assembly is shown for just one side of the
machine, but as it is symmetrical, simply repeat the same steps on the other side as
well. The quantities of the materials to be used for the various assembly steps refer
to both sides of the machine. The weights given near the major components may
vary by +/- 5%.
NOTE: What we are about to describe is an approximate assembly procedure. Each
person, based on their experience and on the tools they have to work with, may vary
the assembly steps to suit their needs. Always use great caution because the
assembly steps are dangerous.

assembly 1 using pin 5, washers 6-7
and bolt 8.
Insert the grease nipples 9 into the
openings in supports 2-3 and in the
crosspiece assembly 1.
In this step, you will use:

given in the drawing at the side.
Note: The central holes A in the
lower flanges of supports 2-3 must
be on the inside.

crosspiece assembly 1 and to seats C on the vertical supports 2-3. Part B of tie rod 4
goes to seat A on the crosspiece assembly 1 and part D goes to seat C on the vertical
supports 2-3. If a small adjustment must be made to adjust the length, loosen nut E,
rotate the head D until it reaches the right length, then lock in place with nut E. Connect
fork B on tie rod 4 to seat A on the crosspiece assembly 1 and part D of tie rod 4 to part

done either with a support K or
with a forklift W. Chocks H must
also be applied to the wheels.
Proceed with caution in the next
assembly steps, even with the unit
stabilized.

measurement is with the cylinder to which it is attached completely closed, and the total
pipe length must be 1670 mm – 65.75”.
Now attach sections 3-4 (RH-LH – 65kg/143lbs) to sections 1-2 (RH-LH) using bolts 5
and nuts 6.

into the holes in the plate with bolt
2and into holes B in the sections.
Place the bushing 4, spring 5 and
washer 6 over the plate 2 bolt and
put nut 7 on the bolt.
Note: the more spring 5 is
compressed by tightening nut 7, the
more the turning of the wheel is
braked, therefore check that it is
adjusted properly when the

You have now reached this stage
of the assembly. The machine
rests on its wheels and thus has
good stability. However, continue
to use great caution during the
rest of the assembly, so as to work
safely. In order to work better,
spread apart the right and left
sections of the machine.

bolts 6 and nuts 7.
In box A the
theoretic
measurements are
given for the
assembly of arms 3-
4and counterplates

necessary to move
the arms 3-4 and
counterplates 5
slightly forward or
backward to allow
the correct
installation of the
cylinders.

(see next page)
Note: for logical sequence purposes we describe the assembly of the rake wheels to the
machine frame, but given their bulkiness, if you wish to work with more room available
skip ahead to the assembly of the hydraulic system and then come back to the assembly
of the rake wheels.
First insert the nylon bushings 1 in the all the seats A in all the sections (RH-LH). Next
insert the rake wheel arms 2-3 (RH-LH) in all the seats A in all the sections and secure in
place with the washers 4 and spring pins 5. Attach the rake wheels 6-7 (RH-LH) to the
