Supercharged Camira..

Back to the good stuff

Ok back onto topics that people actually care about. In our last camira related post, we mentioned that we had been waiting on modifications to our camry crank pulley. We’ll after we were about to give up on the person who was suppsoed to be doing the mods, something finally got done.

Unfortunately there is still more to be done after we ran into a couple of problems. The machinist made a really nice sleeve to expand the width of the pulleys internal shaft, as we needed somewhere to drill the required screw holes. The shaft depth on this pulley is approx 3 times longer than the camira pulley. So just get some longer bolts you say, well turns out the original bolts have an unusual thread, and are very hard to find in the required diameter/length.

We then came up with the idea of countersinking the heads down far enough so that the existing bolts would work, however they also have rather wide heads on them which would have split the shaft and make it weak. So the solution we came up with? We drilled new holes (8mm) at a 45 degree offset to the original holes (so they are now aligned with the keyway). We also need to remove the crank sprocket that the pulley screws into and drill / thread new 8mm holes to match the pulley. The 8mm bolts are easy to come by in the length we need.

So thats where we are at the moment. We intend to remove the sprocket on saturday morning and have the holes drilled saturday afternoon if all goes well.

Pic 2 is a back view of the pulley showing the machined sleeve that sits over the original shaft (the ring that runs through the holes is the outer edge of the original shaft)
Pic 3 is the crank sprocket that we need to remove and drill/thread the new holes for mounting into.

  1. Hi there,

    If my old man was in Oz you could have gone over and borrowed his threading kit to re-thread a longer bolt! doh. He’s over here in the UK with me.

  2. Hey Mark,

    There were plenty of threading tools in the machine shop, however these bolts just seems to have a non standard thread. We have to thread the crank sprocket anyway once we drill the new holes.
