Not sure where to post this. So i figured this would be the best spot.

Just completed my timing/water pump/crank/cam seal replacements.

And like others the harmonic balancer removal is a bear.

I made my own spanner wrench.
Which made the job super easy.
I'm including the file for anyone else wanting to make there own.

Material:
1/4"x 4"x12" Steel Stock
Tools Needed:
Drill Press
8mm Drill
1 1/4" Hole Saw
Angle Grinder with metal cut off disc.

Print the PDF *make sure to print it at full size.
Mount it to the steel plate using spray adhesive
Then drill the required holes and cut to shape.
For simplicity i just left mine square.

Now u can place it where ever u need,
Support it with a jack.
And break the bolt free and or install the bolt 181 ftlb.

 

the handle's length goes all the way under the chassis right ... can't see on the picture.

and how much will you sell one for if I ask you to make one for me ? you can pm me

btw , I need one for the SC300 dampener and not SC400

 

gerrb:

I think the threads and spacing on the main pulley are the same. RX 300 and SC400 are for sure the same [first hand info]. I eye balled it on GS400 and it appeared they are the same.

I made mine out of extruded aluminum [Step of a ladder].

In RX forum, a member claimed the he used a 2x4 lumber. It never occurred to me to try 2x4 wood as the three holes would have made the tool weak.

What i did was, thread in some bolts then used my caliper to measure the distance between them on center. "8mm with1.25 thread

93' SC400 was 65.5mm

I tried the 2x4 split 4 of them.
I tried a 2x6 split that as well.
I tried a 3/4in piece of plywood for the face plate then bolted a bar to it, this just twisted my bolts and i darn near snapped one off inside the balancer.

I wasted about 8hrs trying different methods, this took me 1 hr to make and works everytime.

 

Thanks Salim for the info !
