| Can't believe i didn't take a post cleaning picture but I didn't, have to take my word for it that it cleaned up nicely. |
 |
| After cleaning I was able to see some 'brindling' on the bearing race. Have to decide weather or not to replace the bearings on the hub. Not sure it will make to much difference if it's cleaned up and greased? |

| Taking the springs off the shocks |
 |
| Interesting for the fact that the spring has OEW and red overspray |
 |
| Cleaned and painted radius arm |
 |
| Springs? Cleaned and painted |
 |
| Cleaned up, control arm ready for paint tomorrow. |

Are those marks brinelling or false brinelling? I've heard false brinelling is pretty common on IRS bearings since they don't move very far. That grimy IRS is going to be a thing of beauty when you are done.
ReplyDeleteInteresting point Drew, how do you tell the difference? These certainly were not moving, in fact I think that all the bearings in the suspension were sliding instead of rolling....
DeleteI don't know a whole lot. I read about false brinelling sometime back on JL. False or not I believe there may still be damage that requires replacement, but I am just now learning about aspects of an IRS rebuild. JL probably has reliable info on how to tell them apart and deal with them. Brinelling is permanent damage caused by a heavy load event and false brinelling is caused by wear over time. More info on them here: https://en.wikipedia.org/wiki/False_brinelling
ReplyDeleteThanks Drew
ReplyDeleteLynn, I found the same when I re-did mine, and I replaced all. However, I would not do it again, at least with the level of "damage" I had. On mine, you could see marks, but you could not feel them. Seems like if you can't feel the difference, and the assembled units work smoothly, I'd leave things as they are. You also have to consider whether the replacement stuff will be as hard as the originals; we have seen that when measured big differences are sometimes found. James Douglas did this and finally had to get special hardening done to match the originals. (I don't recall what part it was, but you can probably find out from James.)
ReplyDeleteThanks Jerry, I appreciate your thoughts on this. Your right, it sometimes seems like a crap shoot with some of the aftermarket parts.
DeleteFor the front suspension, I ordered Timkin bearings for Ruby. Shouldn't they be as good or better than the originals?
ReplyDeleteHi Drew,
ReplyDeleteI think Timkin are the best but that being said I had issues with some that were manufactured in Poland under the Timkin brand.
