How to Make SST 09817-16011 ( Special Service Tool )
For H55F use
For H55F use
I Recently had the Experience of having the Need to replace the Backup Lamp Switch on a H55F that was from my viewpoint a clean conversion . The 1/79 FJ43L-KC came to my shop due to a no Back-Up Lamps Issue , I assumed it was a wiring problem of some sort & traced the 2 Leads to be frayed at the switch itself where they come out the " Micro Rubber Grommet " .
As i was examining the Leads the HEX shape switch began to move to my surprise and was simply finger tight / loose .
I then Sourced A New JDM switch & after removing old bad one by hand , installed new Switch & a
New OEM Crush Ring Gasket 90430-A0003 by hand . This is when I Reached for the 27mm pause button
There are casting details on this H55F to the aluminum shift tower that will cause interference & prevent
the Use of a standard combination wrench box or open end to turn & use in order to Torque Down and seat the New back -Up light switch , and Aluminum Crush Ring Gasket
The P.O's in Bogota , Columbia seem to had the same issue 10+ Years ago and why they never finished
this job that day either ?
I Immediately thought of a O2 sensor socket & Hunted for the correct size 27mm at all my local
auto parts store's , NAPA & even called my Snap-On man who said a week or two and like
$100 + ...
With money & time on mind I decided to consult my Trusty Shop manual Pub. No. 36262E
Chassis body ( Heavy duty) 60 & 70 Series to see what if any SST Special service Tool Toyota Recommends . There diagram shows what looks like a BIG O2 sensor socket with handle and groove on one side for clearing the Leads coming out side of a Back-UP switch or 4WD indicator switch as well .
I decided to try to make my own Using A Thin Wall 27MM Chrome Socket , as a Black impact type will be to thick and Not clear the shift tower casting design features . I purchased a 27mm Deep 1/2" drive Chrome 6 point at Pep-Boyz for under $10
I took some basic measurements and marked the socket with body shop tape ,also body shop tape prevents chrome from chipping on edge like glass , using a dremmel tool & a reinforced disc. carefully cut away only ONE of the 6 HEX sides out , having to use notch's at the 2 intersection cuts at the top . if more then one Hex is cut away the socket will loose it's grip and bite ability
I later found out toyota's SST is a 12 point socket , but only high end tool suppliers like snap-on sell a 27mm 12 point deep 1/2" drive chrome , & the 6 point did the job just fine
I then used a small round cylinder shape dremmel grinding stone to ease inside corners and other sharp edges that could cut the new Leads up while My NEW / NOS Shop -Made SST would now be in use !
The end result was My Custom Shop-Made SST 09817-16011 ( Special Service Tool ) did the job on the back-up switch install as outlined in Shop manual Pub. No. 36262E Chassis body ( Heavy duty ) page MT-38 & C-6
