Wife always complains about coffee thermos too tight..

 

Have you contacted ARP to inquire when or if they will continue to produce 250-6303?

Some distributors indicate that an order will ship as soon as April 5 (eg M&D Distributors).

It would be a shame to have taken the motor down this far, only to reinstall stretched rod bolts.

 

They're thinking July or August, maybe.

To be clear, the International manual does seem to indicate you can re-use them.

 

Not to ask a stupid question... but have you called your closest/prefered international dealer and checked inventory and prices from them?

 

International can order them but they want 26 per bolt which is just insane. Some dealers around the US have the Ford bolt for 16 or so but usually only one or two on hand.

 

Well hell if you’re going to pay that much for the bolts you might as well buy billet rods that come with new bolts.

*ducks and runs*

 

Even if I wanted to they all seem to be out of stock anyway : /

I suppose if I really wanted to be cheap I could order a couple bolts from International and see if my bolts are indeed stretched.

 

These guys may have them in stock.

Based on what I'm seeing elsewhere I doubt it. There's one place that might have the Crower rods but I can't justify two grand on rods for a mild HP application.

One International tech I spoke with said that, per their manual, there's no indication that they are "torque to yield" or need replacement assuming they are in good condition. I have a line out to another tech who'll get back to me next week.

 

Justify it for a high-HP build then. 😁

I don't think that bolt stretching can be measured.
Unless they have been stretched to braking point.

Maybe try to source bolts by specs only?

This is apples to oranges comparison:

ALWAYS when forestry machine track extension splits off,it's becouse of assembly with the old tired bolt.

 

If you're referring to measuring a bolt that is been removed and being measured, I think you may be correct. I do know that ARPmakes a device that you would indeed measure rod bolt stretch when torqueing them down.

Rod Bolt Stretch gage

 

I think you meant yield point.



I like the idea behind finding a bolt by spec. The trouble is trying to find the exact spec of the rod bolt.

 

Not rod bolts, but an example of necking that is handy for illustration.





Almost every red-blooded vehicle owner has experienced a little bit of necking.



And when things become too strained... it might be time to replace what was necked.
