Mk1 rod end help...
It's a long shot...
Does anyone happen to know what the part number is for the right hand threaded 3/8 rod end (as used on the Mk1). It's made by Aurora

Aurora AM6T - 3/8 Bore, 3/8 24 UNF Thread x 1.25" long, 9544Lbs Radial Static Load Capacity, 12 degree angular movement.
"AM" = Right Hand, "T" = Teflon liner.

If you already know - why am I asking on your behalf?

Re: Mk1 rod end help...
Only just learnt a few minutes ago. If you want to store the data and delete the thread thats fine.
I thought I would post the answer as I have probably driven a number of people mad with all the PMs.

As this bearing is not currently stocked by any of the suppliers in New Zealand I have used an equivalent from QA1 of the USA. The QA1 XM rod ends are constructed from chrome moly steel and have a hard chrome plated, precision ground, 52100 bearing steal ball. Both metal components are heat treated. The race is Teflon® /Kevlar®, self-lubricating and self-sealing.
Below are some other cross references for the 3/8 male rod end:
Aurora   AM6T
National  TSMX6T
NMBÂ Â Â Â ART-5ECR
Rose    RC05H
FKÂ Â Â Â Â Â JMX6T
QA1Â Â Â Â XMR6

I know this counts as thread necrophilia, but I just saw this again due to the MK 1 forum re-organization and it is a very important issue.
The QA1 web page says the race is "Kevlar® Reinforced Nylon 12 with PTFE Lining" constructed with "Loaded Slot Injection Mold". If that is anything like the Aurora SPM, it can have serious consequences when it fails. Click here for a picture.
If you can't find a local source for the Aurora products, you can PM me and I'll send you the name of the Aurora application support engineer I talked to, and he can point you in the right direction.

Re: Mk1 rod end help...
Terry,
The QA1 rod ends I have look nothing like the picture of the Aurora one you have linked to. They have far more metal to them for one thing. What's more the local company that I purchased them from is a supplier to motor sport, in particular Speedway. In NZ Speedway is raced on rough oval dirt tracks, not smooth seal. The rod ends need to be able to take a hammering. My have done 1000's of kilometers now and show little sign of wear.
Aurora AM Rod ends have 9544Lbs Radial Static Load Capacity. QA1 XM Rod Ends also have 9544Lbs Radial Static Load Capacity.
You can read about the QA1 XM here

Re: Mk1 rod end help...
Mine (the incorrect Aurora part shown in the picture) was fine for 7000 miles, before it dropped the frame on the ground. If it had been in the front instead of the rear, it could well have been fatal.wisp wrote: The QA1 rod ends I have look nothing like the picture of the Aurora one you have linked to.

This was something I noticed when I looked at over a half dozen different manufacturers of rod ends. Either loads of people are using the exact same computer models, or there's some copying of datasheets going on.Aurora AM Rod ends have 9544Lbs Radial Static Load Capacity. QA1 XM Rod Ends also have 9544Lbs Radial Static Load Capacity.
The weakest point on male rod ends is generally the area near the head where the threads stop. Strength variations there (aside from changes from varying the size) are likely from differences in the metals used. That's probably also why parts from different manufacturers often have the same rating. But if the bearing race loosens up, that will cause rapid repetitive radial shocks, leading to an increased chance of failure.
Yup, that's very similar to the QA1 page I linked to in my reply. I'd still be worried about the "Loaded Slot Injection Mold" construction.You can read about the QA1 XM here
I've never seen one of these parts in person, so they may well be perfectly fine. I'm just telling you what happened with a part with similar construction from Aurora.
