At the risk of seeming stupid or breaching some unknown forum etiquette I am asking for help in finding the correct torque values for all the bolts and nuts involved in replacing the sc 430 water pump and timing belt. Although their is an excellent article with photos of the timing belt procedure, I am unable to find the torque specs. Now I know I can do as some do and use blue locktite and just snug things up nicely, but my experience with aluminium engines has shown me that if I can find the exact spec, use it. I don't seem to be able to find a service manual for this car in the usual cheap (and somewhat crappy) Chilton's or Hayne's books, and my local dealer is rather difficult to get trustworthy information from. I tried to get information from the RX guys forum as someone here suggested and was told nicely to take my sc questions to the sc forum. Any help?

Sorry you got chased off the RX forum. I, for one, was really looking forward to seeing the bolt together tool you said you developed for harmonic balancer removal. Are you going to share that info here?
Thanks,

I have the 2003 SC430 repair manuals. I believe the engines are the same for all years. As you know, there are many fasteners involved with a water pump and timing belt replacement.

For the water pump, the five bolts, two stud bolts and nut are listed as 18 N-m ( 185kgf-cm, 13 ft-lbf ).

The section for the timing belt replacement runs from 14-114 to 14-123 in Volume 2 of the repair manual. Unfortunately, I could not find a consolidated section with bolt torque specs. They list each fasteners' specs either on the detail diagram or in the text at the corresponding step. Hopefully another member that is more computer capable than me can somehow post this section for you. Short of that, I can make copies of the pages in that section and mail them to you. Just PM me your address.

I will share photos later today, but tool is really quite simple and should work for many different engines. Use two pieces of steel or aluminum angle that is made with holes already punched along both surfaces (usually available at hardware or "box stores". Cut one piece long enough to bolt to one hole of the pulley and lock against the cars frame rail. Cut the other piece about one foot long and bolt it to the other crank pulley hole, using either flat washers, sections or old steel water pipe or oversized nuts as spacers between the recessed area or the pulley and the back side of the angle iron. Bolt the angles to the pulley such that you can then move the free ends together and use one short bolt to join their free ends and form a long thin triangle. Rotate enough to lock the big bar against the frame and use your biggest breaker bar (and maybe a cheater pipe) to loosen the crank pulley bolt. Mine came off very easily and the same tool will be used to hold the pulley when torquing the bolt back on. Did you also check that the bolts used to install the tool to the pulley are not so long they go through the pulley and into the plastic cover behind it? Mine did so I will use a small dab of RTV to fill to hole I made. Photos to come, but I hope you get the idea. Simple no?

Ok, here is 1st attempt to post photos of crank lock tool. Hope they are clear enough.

Simple and elegant. I love it!
Well done and thanks for sharing.
