Since I’m planning a transmission fluid change, I’ll have to loosen the bolts on the diagonal bars for the rear suspension.
I found that the nuts/bolts on these should be tightened to 65 Nm/48 ft-lb; but have also seen some information that the bolts connected to the body (I think the most forward bolt on each side) have a higher torque spec, maybe 88 Nm/65 ft-lb.
Can anyone confirm the torque spec on the nuts and bolts for the diagonal bar? Does it differ for any of the nuts/bolts?
This is for my 2012
987.2 Cayman
Your numbers certainly rings a bell for me when I was working under my 2010, and sounds right for a
987.2
.
The forward most nuts of a
987.1
has an even higher torque spec ( a bit north of 100, I think?), which can cause some confusion when looking up specs online. The rest of the bolts are the same between the two sub-generations.
I cut a 1 1/2 - 2 inch hole in the brace to avoid disassembly
I was looking at doing that while I've got the car up on
quickjack
. With that brace pan in place I couldn't tell exactly where to drill so the drain would be centered in the hole. Didn't want to guess so I passed on it for now. Maybe some other time. I only have 30K miles since the last time. If anyone has a good idea where to drill, let me know. There's already a small hole there on the center line to use as a reference point.
At some point I heard 110 Nm (I think) for the most forward bolts. Maybe this was for the
987.1
. I'll try to find it again; but will probably do 88 Nm for my car. If I remember, I'll throw a
torque wrench
on and see where they're at before I remove them.
This video
may help you locate where to drill.
I'm hoping to do this job soon and do a write up after including instructions for drilling this cutout.
... just waiting on LN Engineering to send me the magenetic transmission drain plug they had backordered ...
Thanks for the video tip. I was hoping to drill the ~2" hole while the skid pan was still attached. I think there is enough clearance between the plate and the oil pan as long as the pilot bit isn't too long. On my previous tranny oil change, I had a hell of a time getting the braces re-attached. At that time the Porsche was my daily driver so I was in a hurry to get it back together and didn't take the time to drill it while it was off the car.
