Should you observe any damage on any of the delivered crates or palettes please annotate this in the delivery documents and notify dynoKRAFT immediately per email (info@dynoKRAFT.de) by sending us a copy of the annotated shipping documentation.
Without a copy of the shipping documents with appreciate delivery-damage notes, signed by carrier, we will not be able to process your claim!
In most cases the dynoKRAFT dynamometer is delivered on disposable wooden palette, wrapped with black stretch foil.
In case of over-sea transport the dynamometer is delivered in closed crate and wrapped in protective foil. In addition to that an humidity absorber may be found inside the packages.
Additionally an protective wax-film may be found on non-painted surfaces. This film should be removed/cleaned with appreciate non-corrosive and non-abrasive chemicals and cotton cloth as required.
Please take care of your environment and dispose or recycle all packaging materials according to your local regulations and laws. 

1. Open the wooden crate using crawl-bar or similar tool. Please proceed with care not to damage the equipment.
2. After opening the crates / removing all packaging material make sure that all parts are delivered as per packaging list and this manual.
3. Remove all coverings from all parts of the dynamometer to allow easy access to the internals of the chassis / frames.
4. Using fork-lift relocate the frames on the palettes near the intended installation place. Then you may unscrew the dynamometer vibration damper feet from the pallet using TX40 bit.

Initial checks

Before installing the dynamometer make sure to check following:
1. Please check the flatness of the surface/floor on which you plan to install your dynamometer using spirit level. Required flatness is min. 2mm per 1m of length in any direction.
In case your installation place does not meet this requirement it may be necessary to use sheet-metal plates to level the dynamometer accordingly.
Such spacers are to be installed underneath the vibration dampers, between the workshop floor and the dyno feet.
DO NOT loosen the vibration dampers from the dyno chassis and install any washers to rise/lower the main frame.



2. Please clean the floor from any dust and dirt. Make sure it's not slippery.
3. Make sure that you have all the tools and hardware required for the installation. This will speed up the process.

00. Pit installation: Wall profiles (OPTIONAL)

NOTE: This step is applicable only in case you're installing the dynamometer in a pit.
Before lowering the dynamometer into the pit make sure to install the grating support profile (marked green below) on the back wall of the pit, using provided M10 (M12) concrete anchors.
Should you lower the frames into the pit before installing these wall-profiles you may experience difficulties when doing it at later stage.




Support profile installation height is 518,5mm (approx. 20,4" ):



0. Subframe

Start the assembly process by positioning the Subframe in the intended final installation place.
The subframe carries the FRONT ROLLER (in driving direction) and it's adjustable to allow different wheelbase settings.
Lift the front Subframe using one webbing sling, or similar, near the drive shaft bearing support (at the center of gravity), so that it can be rotated 180 degrees once hung.


Rotate the Subframe 180deg then gently lower it in place. Note the position and orientation of the blue gearmotor-drive.
Use wooden blocks and rubber pads not to damage the paint.




NOTE: This step is applicable only in case you're installing the dynamometer in a pit.
Position the Front frame in the pit as per drawing below (rear pit wall to subframe ~220cm)


01. Front Frame

Lift the Front Frame using two slings - one on each side of the chassis.
Route the sling through these holes in frame (marked green below):



Like that:

Please note the orientation of the chassis / position of the retarder -> on the LEFT in driving direction.
Position the Front Frame above the Subframe and lower it.




While lowering guide the Front Frame into the threaded M20 studs found on the Subframe cradles.
DO NOT tighten these nuts yet.


02. Horizontal bars

Install lower horizontal bars into the Subframe and tighten losley (by hand), so that the bars can be moved freely to left or right at later stage of the installation.
No lateral movement is allowed. Support the free ends using wooden blocks.


Note the orientation of the bars:



03. Rear Frame

Lift the Rear Frame in same way as shown in chapter "01. Front Frame" and position it close to Horizontal bars / lower it in place.
Please note the orientation of the chassis / position of the retarder -> on the LEFT in driving direction.
Keep the Rear Frame swinging in the air, just few millimeters above the ground, before attaching the Horizontal bars - this will ease the installation:


Bolt the Rear Frame to the Horizontal bars using supplied M12 bolts and self-securing nuts.
Tighten it loosely so that the Rear Frame can be still moved to left or right, but in lateral direction (in driving direction) there is no exessive free-play possible.





04. Angular axle position

Before tightening the M20 nuts on the Subframe cradles please verify the angular position of both Front and Rear Frames with respect to each other.
To do so please place the spirit level on the side of the rollers and press it firmly against the roller side.
In the example below the FRONT Roller is base for this check while the REAR roller shows some distance to the spirit level (represented by green line in drawing below).



Measure the difference in this distance between two edges of the same roller so verify that the angle between axles is near 0 degrees.
NOTE: Due to manufacturing tolerances the distance X must not necessary be exactly 0 - some offset is allowable - usually less then 10mm.



If X1 = X2 the angle is zero
If X1 ≠ X2 the Front Frame angle "A" must be adjusted on the cradles accordingly



After the axle angle has been setup please tighten the M20 nuts bolting together the Front Frame and Subframe cradles.:
Torque: min. 150Nm



05. Link shaft installation to Rear Frame (slit version)

Suspend the Link Shaft in the air to ease the installation.
Make sure to have the central support bearing moved onto the Link Shaft as shown below.


Attach compressed air to the Air Supply inlet and release the pneumatic brake calipers by pressing the orange button on the pneumatic valve.


While holding the pneumatic valve open rotate the rollers so that the feather key on the Link Gearbox is on the bottom of the output shaft.


Using flat-head hammer-thru screwdriver widen the slit in the cardan-joint:


While having the screwdriver positioned under an angle insert the Link Shaft through the hole in Rear Frame


 and move the cardan-joint over the Link Gearbox:


If the joint is hard to install on the output shaft you may use crawl-bar to push it in.
Caution!
Do not excessively stretch the cardan joint with the hammer-thru screwdriver as you may damage it.


Push the universal joint over the output shaft so that approx. 3mm of free play to the joint itself is provided.
Look through the slit - the output shaft must not touch the joint itself:


Install two 80mm Collar Clamps over the Universal Joint to clamp it on the output shaft of the Link Gearbox.
With the dyno there are a total of 4 clamps delivered. On some dynos with pre-glued shaft Support Bearing two of these clamps are used to secure the bearing during shipping.
Please re-use them to secure the cardan joint.

Mark the bolt heads with paint marker as shown.
Torque: 34Nm
Caution!
This is critical step thus make sure to keep the specified torque of 34Nm.
Please make sure to orient the slit of the Collar Clamp directly above the slit in the cardan-joint itself.


06. Link shaft installation to Front Frame (slit version)

Connect the Compressed Air pass-through hose to supply air pressure to Front Frame and connect the air coupling inside the Front Frame.
Connect the black power connector to electric cabinet (found on the back of PC-trolley). 
Turn the Mains ON and press green "Reset" button to supply electric power to Front Frame gearmotor drive.
You may use the Wheelbase adjustment during this step to ease the installation of the cardan-joint on the Link Gearbox.
Simply press the respective button on the wired remote to move the Front Frame back and forth.

While holding the pneumatic valve open rotate the rollers so that the feather key on the front Link Gearbox is on the bottom of the output shaft.
The feather key itself is held in place using cable-tie, which will be removed during this installation as soon, as the cardan-joint is moved over the key.


Using flat-head hammer-thru screwdriver widen the slit in the cardan-joint, which is later installed into the Front Frame:


Move the cardan-joint over the gearbox shaft and pull the screwdriver out:


Then relocate the hammer-thru screwdriver to the inside of the frame, slit the cardan-joint again and remove the cable-tie:


Push the joint further so that it's flush with the housing.


Remove the screwdriver and install 80mm Collar Clamps in similar manner as previously in Rear Frame.
Mark the bolt heads with paint marker as shown.
Torque: 34Nm

Caution!
This is critical step thus make sure to keep the specified torque of 34Nm.
Please make sure to orient the slit of the Collar Clamp directly above the slit in the cardan-joint itself.


07. Support Bearing part 1

After installing the cardan joints on both ends please adjust the wheelbase to the middle setting by pressing the respective button on the wired remote.



Loosely install the fixing brackets on the Support Bearing housing



and push it against the Subframe:


Mark the bearing position over the shaft to determine the position of the bearings inner race.
Apply medium thread-lock (glue) around the whole circumference of the drive-shaft, to glue the inner race onto the Link Shaft.

Push the Support Bearing back in place (push against the Support frame as shown below) before the glue dries out!
Leave the bearing for min. 15 minutes to let the glue set.

Caution!
On dynos with pre-glued central Support Bearing this gluing operation was performed during manufacturing of the dyno.
In such case please spread the cardan-joint slit in the Rear Frame before pushing the Central Bearing against the Subframe.
Should you try to bolt down the central bearing without spreading the slit in cardan joint and pushing the bearing housing agaist the Subframe
you will damage/tear the vulcanized rubber in the bearing housing.

08. Central Bridge part 1
