skyludeboy Posted October 3, 2011 Share Posted October 3, 2011 I am in the process of rebuilding my engine using arp rod, main and headstuds, for the rods its specified at 28 ft.lbs do I apply this setting plus 90 degree turn as stated in the factory manual? Also main studs I lost the paper which had the specs on does any one know what the torque for the main studs should be? Thanks Quote Link to comment Share on other sites More sharing options...
Scott Posted October 3, 2011 Share Posted October 3, 2011 I did the head studs a few weeks ago. I think it was 80ftlbs off the top of my head. They aren't stretch bolts so the 90 degree turn thing doesn't apply, you just follow the instructions with the studs. The only part of the manual process you follow is with regards to the order.

skyludeboy Posted October 3, 2011 Author Share Posted October 3, 2011 I also recall in my head a figure of 80ftlbs but lost the damn paper, also the rod bolts remain at 28ft.lbs also no need to do the 90 degree turn right? Quote Link to comment Share on other sites More sharing options...
Scott Posted October 3, 2011 Share Posted October 3, 2011 I didn't do the rod bolts, I just followed the instructions I had to the letter mate. Are the stock rod bolts stretch bolts also? Quote Link to comment Share on other sites More sharing options...
skyludeboy Posted October 3, 2011 Author Share Posted October 3, 2011 yeh stock are stretch bolts so are arp ones I am assuming you can follow factory manual procedures Quote Link to comment Share on other sites More sharing options...
Scott Posted October 3, 2011 Share Posted October 3, 2011 The ARP ones are stretch? The head studs definitely aren't, that's why they are torqued far higher than stock. Quote Link to comment Share on other sites More sharing options...
skyludeboy Posted October 3, 2011 Author Share Posted October 3, 2011 Yeh they are same as factory rod bolts 1 piece with arp 2000 stamped on the head and eagle logo came with eagle rods Quote Link to comment Share on other sites More sharing options...
Scott Posted October 3, 2011 Share Posted October 3, 2011 No idea in that case bud. I would just go with the instructions though rather than the manual. http://arp-bolts.com/pages/technical_torque_us.shtml#usrodbolt Quote Link to comment Share on other sites More sharing options...
Scott Posted October 3, 2011 Share Posted October 3, 2011 http://arp-bolts.com/instructions/203-4205.pdf Found that too, that's the instructions for the head bolts. 80lbs right enough Quote Link to comment Share on other sites More sharing options...
Scott Posted October 3, 2011 Share Posted October 3, 2011 I think I've found the rod bolt info. However, it seems you may be working with something completely different as it says in here to torque them to 65ftlbs whereas you said it told you 28? http://arp-bolts.com/instructions/203-6005.pdf Quote Link to comment Share on other sites More sharing options...
skyludeboy Posted October 3, 2011 Author Share Posted October 3, 2011 i just realised I was looking at the wrong head size the head I have is a 11mm multipoint head which I think is 7/16" size equates to 43 ft. lbs reckon I still need to do the 90 degree turn with this applied? I am getting the figures from the spec sheet that come with eagle rods Quote Link to comment Share on other sites More sharing options...
Scott Posted October 3, 2011 Share Posted October 3, 2011 In my opinion I would say no, I would get clarification from someone else though. The ARP bolts will stretch differently to OEM bolts, therefor you will need to follow the ARP instructions.... IMO anyway. Are the instructions you have not specific to the bolts you have? Are they just generic instructions like the table I listed above? If they are I would contact Eagle or a distributor and find out exactly what you should be doing. If I were in your shoes I would contact ARP direct though as noone is going to know better than those guys. Quote Link to comment Share on other sites More sharing options...
