Thread: Does this look right

When you say the bolts dont come out easily what exactly do you mean - once cracked they should come out of the conrod easily enough - don't just undo each bolt individually - loosen one a bit then the other a bit and back to the other etc. Most should come out of the bottom part of the conrod (not sure what it is called) but I did have two bolts that would not actually come out of the bottom part of the conrod but did no cause any issues in the rebuild process.

The bolts should be splined (if that's the right word) so they fit through the top side of the conrod without spinning. They should be quite difficult to take out.

They are 'supposed' to be single use only as well.

That is the whole of the bottom end of the conrod - but the removable bit that contains the lower bearing shell of big end must have a specific name.

You cannot actually pull the big end off the conrod.

I meant after cracking them one side at a time then taking them out each side a bit at a time as Gary said, even when they were half way out they still would not turn by hand, right to the last thread, it became apparent why whn I got them out, there was some type of threadlock goo on them, thould there have been ?

Here is some picss of the bigend bearings and the crank, im bot taking them all off yet cause I have to source a 1-5/16 impact socket to get the crank pulley off and get the cam out as well, so im stuck for the moment.

When I put mine back in on the weekend I thread locked them as an extra precaution so I don't believe it is an issue. While I did not use ARP bolts on these I did for the mains and ARP said it is Ok to use threadlocker on them and I did.

Excuse my Noob questions here but what are ARP bolts and why cant you reuse the bolts?
