Hi Ghibb, Can you give me some more details of the vehicle and what is the intended use of the rod end. Can you also link me to the information confirming the rod end size and radial loading. Cheers Chris

Hi Chris, rod ends are for watts link in 68 Camaro,7/16 bore 1/2” shank , proposed ends are from fk rod ends , RSM 7 or heavy duty RSMX ,radial shear 9685lbs and 23470lbs , regards Hiya Ghibb, I've bounced it around the tech team and the answer is the rod ends will have to meet the minimum sizes and radial load rating. The minimum size rod end you require for the application you've suggested above is a 16mm (5/8") with a minimum radial load rating of 3340kg (7350lb) The problem is at some point in the future as the rod end wears out (they are a common replacement part) they might be replaced with a lower load rated spherical rod end because they are cheaper and we would end up with an unsafe situation. Cheers Chris

Hi Chris, 5/8 being the shank size ? 1/2 bore, the 7/16/-1/2”rod end only comes in the rating that I quoted so possibly of being replaced with less rated joint is nil , regards

Morning Chris, is this worth getting your design committee to have a look at this ? As even a $7.99 qa1 joint in 7-16 bore 1/2 shank is rated at 11000 lb static radial load which is the cheapest I can find in this sizing and all joints I have been able to find exceed load requirements from hctm, regards

What you have only meets the radial loading. Regards Chris

hi chris,table 6.4 in hctm decribes rod end required for weight range of car as a 16mm/5/8"shank 12mm/1/2"bolt rod end as being the reqiured size for my project, table 6.3 states a 16mm 5/8"rod end as needing to have a 7340 lb rad load rating i assume that the 16mm/5/8 refers to the shank size as table 6.4 states only a 12mm 1/2"though bolt is reqiured? Also i cant find any required size for the watts crank centre bolt size, bush/bearing requirments, would it be advisable to design crank povit bush,thoughbolt around the same size as rod end requirment ie 12mm/1/2"if bolt suported on both sides or 16mm/5/8"if it was a stud type povit ie el falcon? regards

In table 6.3 - the rod end size is taken from the shank measurement. So for your Camaro, the spherical rod end size would be a minimum of 16mm shank size, 12mm bolt size and a 7350lb radial load rating. Cheers Chris

Hi Ghibb
A bolt that steps down in diameter to under that listed in requirements would not be suitable. It would need to be at least the diameter listed in the requirements through its full length.
Regards
Chris
