Installing Arp Rod Bolts

[r32r32]

Can anyone tell me what's involved in installing ARP rod bolts to standard rb26 rods?

Cheers!

Take bolts out, put new bolts in.

and then

use ARP moly lube on the threads and torque to the recommended tension

Is it seriously that easy as I have been told differently from a reputable workshop!

It is recommended that the rod tunnel be resized when installing new conrod bolts.

From being on the forums I think DiRTgarage is as reputable as you can get .

Thats what they told me.

Then they are correct. I would almost go from 'recommended' to 'required'.

yes all 2nd hand rods should be at the very minimum closed and honed after new bolts are fitted to ensure big ends are perfectly round and haven't distorted from previous service or the bolt removal and fitting process.

Just to add to that

Also because the new torque required by the ARP bolt can distort the bigend tunnel.

Anywhere from 0.001 to 0.003 difference can be found just by torquing them down to the new figure.

Thanks guys!

How much is it to get them installed?

fit the bolts torque to rec arp tension, measure the tunnel with an inside dial bore guage. if you dont have one a rep shop should measure them and charge zip. sometimes you can pull it off and dont need to close and hone. we always check it that way first, if they are not round in the tunnels from there they will have to be closed and resized. usual cost $30 per rod to resize. basic stuff!!!!!1
