Impellers, Shafts & Couplings

Once the drive end of your mixer is installed on the tank, it's time to connect your shaft couplings (if your
mixer has multiple shaft sections) and assemble the impellers.

Before beginning this stage of the assembly, check to make sure you have all of the components,
hardware and tools you'll need to correctly connect the shaft couplings and impeller assemblies. You can
refer to your assembly approval drawing for a list of all of the parts associated with your mixer.

Cleveland Mixer recommends using thread locking compound on all connection hardware. A calibrated
torque wrench is required to keep balance in the connections and to ensure the connection bolts are
stretched and tightened so they won't come loose during operation.

SHAFT COUPLINGS

1. Each shaft coupling connection will have a male and female register. Check these registers for dirt, dings and dents
that might have accrued during shipment or staging of these components. For proper alignment, it's important these
registers have a clean connection.
2. Once the registers are mated, insert the pre-lubricated connection bolts. Each set of hardware will include a bolt,
split spring lock washer and a nut. You can check your assembly drawing for the wetted parts material of construction
to make sure you're using the correct hardware. The hardware will be either 316L stainless steel or zinc. Stainless steel
hardware should be used in sanitary or corrosive applications.
3. Add a few drops of thread locker and hand tighten the nuts to the lock washers. Use the torque chart from this
manual to find the torque value for the size of the bolt. Torque the nuts down each of the nuts down to the same
value to ensure proper alignment of the coupling connection.

IMPELLER ASSEMBLY

Assemble the impellers using the same procedure described above to tighten the connection hardware.
1. Check the center bore of the hub to make sure it's clean from dings, dents, scratches and dirt. The bore tolerance
might be as close as +/- .005", you don't want to force the hub on the shaft. Forcing can cause it to gall up and get
stuck on the shaft. Check the hub for the marking "TOP" make sure that side of the hub slides up towards the mixer
drive. The hub should slide up the shaft nice and easy with minimal assistance beyond supporting it's weight.
2. Starting with the top hub (if you have multiple impellers) slide the hub up over the key slot.
3. Insert the key into the key slot with the gib end down. You should be able to slide the hub down and let it rest on the
key without a fastener.
4. Add a few drops of thread locking compound or fastener lubricant and torque the set screw to the key. The set
screw should line up with a dimple in the center of the key.
5. Fasten the blades to the bottom of the hub ears. Blades with stabilizer fins should have the fin side down. Double
check this assembly before operating the mixer. Operating the mixer with the blades or hubs on backwards or upside
down can cause catastrophic damage to the mixer.
