Install and torque rod bolts in closed up case?

Hi all, how do I install the last piston rod in the case? How can I ensure that the rod bolts are landed? How can I torque using the nut rotation gage? Thanks in advance. Cheers, Mike.

No responses yet?

You should be able to install each con rod assembly after the crankcase is assembled. You may not be able to use a torque-angle wrench, in which case use a torque wrench in 2-3 steps to final torque.

Instead of creating a step by step, perhaps a video is easier to follow.

Review the series of engine D&A videos by Nick Falljames. Here's the one on installing the cylinders.

Hope this helps.

Just to complete this thread, another variation of doing this is to install individual con rods after the crankcase is assembled, then install each piston/ring assembly and cylinder individually.

After installing the cylinder base gasket, install one piston/ring assy. onto the con rod (with one pin circlip first installed in the appropriate side), then slide the cylinder onto the piston assy using a take-apart ring compressor.

Recognizing there's a limited flash time for most gasket sealers, complete the cylinder blank by fitting and aligning the cam housing to the cylinder heads as shown in Falljame's video above.

Locktite on rod bolts?
ARP recommends (and supplies) their own lube, looks like some sort of moly grease.
I like using a stretch gage, which obviously only works if the crank is outside the case.

I don't have Wayne's book with me but I thought it said to use red thread locker on the rod bolts. 1981SC 3.0L no mods. I'll look when I get home. Cheers.

Loctite and anti-seize lube don't produce equivalent torque specs. Neither does regular anti-seize and ARP's lube. What are you going to do?

I am not going to take them apart. I used the torque 90 degree method to torque them. I (accidently) torqued them dry, but apparently this is one way to do it.

Thank you.
