I have no Mondeo/Escort manual so can someone tell me the tightening torque for the bigend and main bearing bolts on a 2.0 silver top Zetec...............just been checking the shells.

Hi

If you are using standard bolts you need to fit new ones.

Torque is Big Ends
Stage 1 15 nm
Stage 2 +90 deg

Main bearings 80 nm

I don't have any european manuals, but for a 2.0L zetec in a 2000 Escort for north america the torque specs are:

Main bearing caps 80-90 NM in sequence

Install the connecting rod caps.
Install new bolts and tighten in two stages:
Stage 1: Tighten to 35 Nm (26 lb-ft).
Stage 2: Tighten an additional 90 degrees.

Madman: I'd be amazed if the bigend torque was higher than the mains?????

I agree, posted before I thought. I was thinking Focus and not Escort, I've updated the post and like I said I'm not sure if the european engine is the same. I got the specs directly from the Ford factory online manual, which I'm sure are acurate and up to date
Maybe I shouldn't have posted if i wasn't sure, but I'm surprise that it is different. There must be more variations of the 2L zetec.
On the Focus it is indeed:
Tighten the main bearing bolts in two stages.
Stage 1: 25 Nm
Stage 2: 60 degrees
Tighten the connecting rod bearing bolts in two stages.
Stage 1: 35 Nm
Stage 2: 90 degrees
Dependant on the thread pitch 60 degree may yield a higher torque on the mains.

If I fit ARP bolts do they have to be replaced if removed or are they reusable?

here is a bit about apr bolts from the tiger forum.

there should be instructions, on mine i had to torque them up to 36nm (I THINK!!!) release and repeat twice more, you must use the molly grease supplied and make a note of their precise length for future use, if they become permanently stretched they are scrap!, they must also fit the bearing block precisely to accommodate the chamfer of the bolt between the head and shank. not sure about the zetec but i had to send my con-rods to be checked for ovality and re cut, this is because the caps are not doweled and were held in a new position thanks to the APR bolts, proceed with caution or it may waste the expense of the other work carried out! they are not just strong bolts! its the tolerance in the bolt hole in the cap that gives the added strength, its not as straight froward as many people believe!

Good luck!!!!!!!!!

Thanks for that............

nothing's as easy as it seems is it!!
