Tail rotor grip tool and other tail questions...

[in2deep]

Working on a Srimok 90n classic

I bought my kit second hand, and it didnt include the tool to allow my to take the tail grips apart. Is there a part number for this tool, or anyone know where i can buy one?

Second, I'm having vibe issues (I know, its shocking ) I feel that there is excessive end float in the tail shaft, leading to inconsistent gear mesh in the tail gears. I know the tail gears were updated at some point, just wondering how to tell if I have the new gears? I also thought about buying some extra shims (ksm60-096) and trying to control the slop by shimming on the rotor side of the bronz tail gear bushing (ksm20-t24)

My serial number is 316 and ive put in bold all the items I know have been updated:

SRIMOK 90N 2010 version are improved follow the list below:

1. KSM10-T09 Tail boom support Drive: Make more thickness on top.
2. KSM10-C01 Swash plate : Change material from 6061 to 7075 at Swash plate base.
3. KSM10-C01 Swash plate :Change Spherical bearing from IKO to ELGES.
4. KSM10-F17 Engine Damper support: Change to KSM10-F31 Adjustable engine mount.
5. KSM10-T18 Service cap tail gear box: Make bigger hexagon.
6. KSM20-TS04 Hexagon start coupling: Change to KSM20-TS10 Starter coupling (Hexagon joint).
7. KSM20-TS06 Starter shaft(OS): Change to KSM20-TS11 Starter shaft OS (Hexagon head).
8. KSM20-TS07 Starter shaft (YS): Change to KSM20-TS12 Starter shaft YS (Hexagon head).
9. KSM10-90H02 Main rotor grips (3mm): Change to KSM10-90H08 Main rotor grips set 4mm screw lock
10. KSM10-90H02 Arm grip (3mm):Change to KSM10-90H09 Arm grips blade 4mm screw lock
11. Throttle control rod 50mm (share with KSM20-C09):Change to KSM20-C10 Throttle control rod 60mm.

I know for sure that my main grips and arms are the 3mm versions, the swash bearing and throttle control rod I am unsure about.

Well I can answer one of your questions: KSM10-T04 is the tailrotor grip tool.
