2017 jaguar ftype v6 im trying to find the torque specs for the crankshaft mounting bolts. can anyone help me ?

 

For the crank pulley?

Crank pulley bolt is 200Nm + 270 degrees, it's very tight. There is a special tool to counter-hold the pulley during removal/torquing. Be mindful of the threading, they are reverse bolts.

 

Good info from RoverJoe. For the future, check out the sticky "How To" thread and download the shop/repair manuals.

 

I'm glad I haven't had to remove the crank pulley. I can't recall finding reverse threads on a crankshaft beyond some two-stroke motorcycles of my younger days.

I interpreted "crankshaft mounting bolts" as those for teh main bearing caps, but either way, the downloadable manuals are an invaluable first resource.

 

"the downloadable manuals are an invaluable first resource"

And props to Dave Sperry (DJS) for uploading/hosting those.

 

Yeah that's what I would think as crankshaft mounting bolts, but we don't do internals even at dealer level and it's far less common than the pulley bolt. That's why I asked.

 

it’s these four bolts there’s 4 on each side so 8 total

 

Ahh, we don't take those apart at dealership level so we don't have specs. I will look through the engineering stuff tomorrow and see if I can find it, should be able to.

 

I'm guessing those are the crankshaft main bearing cap side bolts.

 

Thank you Joe!
