dude Posted April 24, 2010 Share Posted April 24, 2010 Go to the Carillo site , there is a chart , if the part no does not come up then measure the bolt diameter. Quote Link to comment Share on other sites More sharing options...
Lee P Posted April 24, 2010 Share Posted April 24, 2010 If they are carr bolts they are done by stretch. Quote Link to comment Share on other sites More sharing options...
StuartW Posted April 24, 2010 Author Share Posted April 24, 2010 From Carrillo Website; "BOLTS All bolts should be lubricated under the heads as well as on the threads. We recommend the bolt lube included, or as an alternative, molybdenum base paste mixed with engine oil. The preferred method to torque the bolt is by using the stretch figure listed in the table below. In order to check bolt stretch, simply fixture one rod, leaving the cap portion free from clamping load. Measure both bolt lengths loose, then progressively tighten the bolt until the measured increase in length correlates with the figures below. Use the indicated torque reading to tighten all the connecting rods in final assembly." 3/8 WMC H6 .0050 to .0070 in .127 to .178 45 ftlb 61 Nm" So i need a vernier caliper that can measure .000 of a mm:blink: Or do i just torque them up to 45 foot pounds?? If the answer is Measuring can anyone suggest where i could obtain such a measuring tool? I have a £60 digital vernier caliper but that just will not be accurate enough, I need like a dial mike or caliper! Many of you on here must have come across and conqoured this problem Quote Link to comment Share on other sites More sharing options...

TLicense Posted April 25, 2010 Share Posted April 25, 2010 The the torque of the rod bolts is the limiting factor on the weakest link inside the engine. Do it right and buy a bolt stretch gauge. I think mine was about £25, just have a look on-line, I'm sure you'll find something. Quote Link to comment Share on other sites More sharing options...

Where did you get yours from Tony, I hate the bloody things and normally do it by torque, never had a problem yet but might be a good time to start using the stretch method.

TLicense Posted April 25, 2010 Share Posted April 25, 2010 I can't remember exactly, but this would do the job nicely. http://carshop.carshopinc.com/product_info.php/products_id/59234/CSRBSG They are definitely fiddly but are the best way of getting it absolutely spot on.

dude Posted April 25, 2010 Share Posted April 25, 2010 I can get ARP bolts from the people who actually make them FOR ARP, can also get them made to any spec. The mark up is amazing dude, trust me. Quote Link to comment Share on other sites More sharing options...

TLicense Posted April 25, 2010 Share Posted April 25, 2010 Why not use the Carr bolts? They're not torque to yield so can be re-used. Quote Link to comment Share on other sites More sharing options...
