   Step thirteen: Verify that "H" arm does not interfere with the slider seal retaining ring. If necessary, mark, and grind as shown on adjacent image.

   Connect TeleFlex cable (hardest part of this job!). Install upper and lower spacers with the champhers facing the rod end.

   Step fifteen: Torque all bolts as specified and safety with .025" SS safety wire.

   Grease new slider with one to two shots of red grease.

   Step ten: Trial assemble TR mechanism and check for alignment and slider travel for binding.


   If everything checks good tighten and torque pulley bolt. Lightly grease slide rails.


   Ensure that shaft bearings are slightly loosened to facilitate self alignment on installed to TB rails.

   Step three: Remove the TR belt intermediate swing pulley.


   Remove the third TR belt from the pulley so that the whole slide assembly can be removed from the TB.


   Identify the pulley spacers "top" and "bottom"

   Step six: Start dis-assembling slide assembly. Remove L/H end plate. Remember that the locking collar should release by a sharp blow opposite TR shaft rotation.

   Note: That some collars may have an additional Allen set screw.

   Step five: Remove TR slide assembly.

​   ​Step two: Requires the existing slider to be disconnected at the "H" arm and from the two TR blade pitch link turnbuckles.

  Step twelve: Re-install intermediate swing pulley. Number three belt is on the upper sheave. Install spacers as previously marked. Tighten bolt to specified torque.

   Locate, by rotation, the Allen lock set screw. Tighten with a 1/8" Allen wrench.

   There are two ways to remove the pulley from the shaft. One is to use heat from a Propane torch or heat gun the other with a three jaw puller as shown.

   Sometimes a 5/8" shallow socket helps to remove completely.

   Disassembly is always the first step to most upgrades. This upgrade is installing a new style slider with a elongated nose. 


   The purpose of the longer snout is to prevent the slider from sliding off the TR shaft keyway and to provide a unit able to be greased via Zerk fitting.


   Step one: Loosen the TR belts and remove the aft end plate.

   Step eleven: Install TR drive assembly. Align slides with TB rails and slide on evenly. Note: DO NOT FORGET TO INSTALL BELT!! Engage Teleflex adjustment rod into R/H slide casting and install bolt.

TR Slider Upgrade

  Step fourteen: Install end plate. Ensure slides are even by measuring their aft edge to the end plate. Tighten aligner bearing retainers to lock bearings.

   Lock the bearing collars in the direction of TR shaft rotation.

   Step four: Disconnect the anti-torque TeleFlex cable. At this time you also need to disconnect the adjustment rod from the TR slide assembly.

   I recommend cleaning the interior with ScotchBrite to facilitate installation. You should also take this opportunity to champher the bolt holes maybe spotface them as well if you have the tooling.

   Last step: Adjust belts to proper tension using pre-flight tension tool. Install tail cone fairings. Actuate anti-torque pedals and verify clearances and smooth operation. It is a good idea to also verify TR blade angles (8deg and 24 deg). Adjust as necessary. It is recommended to torque stripe all jam nuts as a pre-flight enhancement.

   Step nine: Slide new slider onto shaft and mark operating area for continued stripping and cleaning of paint and debris.

   Step seven: Remove TR drive pulley. Identify bolt orientation by marking the head to the pulley. I suggest you also mark the shaft. These are initialy drilled by builders and not perfectly centered. Usually the bolt, pulley and shaft have to be be matched for re-installation.

   Step eight: Remove R/H slide using the same method as with the L/H slide. Clean TR shaft with ScotchBrite.

   Maintain alignment mark for pulley bolt hole as indicated in adjacent photo.
