Installing Decelerators
Installing an R88G-HPG@@@ (Backlash = 3’ Max.)
Use the following procedure to install the Decelerator on the Servomotor.
1. Turn the input joint and align the head of the bolt that secures the shaft with the
rubber cap.
2. Apply sealant to the installation surface on the Servomotor (recommended sealant:
Loctite 515).
3. Gently insert the Servomotor into the Decelerator.
As shown in the figures on the next page, stand the Decelerator upright and slide the Servomotor
shaft into the input shaft joint while making sure it does not fall over. If the Decelerator cannot be
stood upright, tighten each bolt evenly little by little to ensure that the Servomotor is not inserted at
a tilt.
4. Bolt together the Servomotor and the Decelerator flanges.

5. Tighten the input joint bolt.
Bolt Tightening Torque for Duralumin
Note Always use the torque given in the table above. The Servomotor may slip or other problems
may occur if the specified torque level is not satisfied.
The R88G-HPG11@ uses two set screws for the connecting section.
6. Mount the supplied rubber cap to complete the installation procedure.
(For the R88G-HPG11@, mount two screws with gaskets.)
