What's with the weird link address for ebay?

When I copy the link it gives,

When it shows properties its the below.

For a test I'll do a yahoo link.

http://www.yahoo.com/

That's some weird stuff because the properties for the yahoo's link says,
"//api.viglink.com/api/click?format=go&drKey=200&loc=http%3A%2F%2Fforums.rennlist.com%2Frennfor ums%2F996-forum%2F690009-casper-labs-ims-kit.html%23post9425992&v=1&libid=1333775631747&out=http%3A%2F%2Fwww.yaho o.com%2F&ref=http%3A%2F%2Fforums.rennlist.com%2Frennforums%2Feditpost.ph p%3Fdo%3Dupdatepost%26p%3D9425992&title=Casper%20Labs%20IMS%20kit%3F%20-%20Rennlist%20Discussion%20Forums&txt=http%3A%2F%2Fwww.yahoo.com%2F&json p=vglnk_jsonp_13337758744902"

Never seen this weird stuff before.

Dunno but it works if you just click on it. eBay does a couple redirects though including the outbound link...

Interesting, look forward to Jake R. to chime in.

The removal tool almost look like a boat plug puller, looks similar to the one used to remove spark plug oil tubes, which reminds me I have to get one before changing the plugs!

There's a pretty long thread at Renntech in the 996 forum. A person from Casper discusses, at length, their bearing and the R&D behind it.

http://www.renntech.org/forums/topic...c-ims-bearing/

+1 That thread has a wealth of information and in-depth explanation from the manufacturer himself. I found that thread to be the first to explain the conditions that contribute to IMS failure, without all of the wild speculation that is rampant on the boards.

logray

You mean the explanation on LNE's site didn't teach you anything?

http://www.lnengineering.com/ims.html

Jump forward to the "Why do intermediate shafts fail (or rather, why do the bearings fail)?" section... most of what Bill said in the RT.org thread is also said on the LNE site.

Palmbeacher

Bill is an engineer, Charles and Jake,experienced as they may be, are not engineers. From the standpoint of a (former) fellow engineer, Bill's explanation(s) are backed by science, whilst Charles' and Jake's sound evidence-based with a smattering of intuitive guesswork and sound-bites from their phantom "retired Timken bearing engineer". That is NOT to say they are wrong or misguided. I feel more confident hearing another physician explain some medical issue to me than a lab tech. Call it professional bias if you want, but there it is.

That said, the Casper retrofit re-uses the original shaft and flange whilst the LN retrofit contains a proprietary shaft of larger-than-OEM diameter, and as a result, a proprietary flange as well. So dollar-for-dollar the two are probably of similar cost. Bill believes the chances of a shaft breaking are not significant enough to warrant upgrading it, whilst Charles and Jake disagree. Personally, even if Bill is correct, I don't see a downside to upgrading the shaft specs. The overwhelming majority of the cost of the retrofit is labour, so another couple hundred in the part for a more complete kit doesn't seem like bad value at all.

its always good to have choices

Anyone ever hear any more about the Casper Labs solution? Just curious, as I am likely going to just have Flat6 do the Ultimate Solution, if not unreasonable, down the road, but, still nice to have choices..

The only thing custom in that kit is the spacer. I've made my own kit using a ceramic hybrid bearing that I bought for $100. Been in the car for 2500km. It's a little too early to declare it as another alternative but things look very promising. The thread is on the a Canadian forum under "I dragged home one of these".

dph928

I am maybe missing something here, but the primary issue appears to be a lack of bearing lubrication and the solutions offered are more robust bearings in addition to allowing engine oil to enter the bearing without a reliable feed. Would the correct/optimal solution not be to use a hollow pin/center bolt with perforations to supply oil directly to the center of the bearing, this in turn could be fed by a metal tube (to guarantee it remains securely in position) passed through the bell housing and connected to the head. This maybe prohibited by the space available behind the flywheel, not having had my 996 in bits yet I don't know, but perhaps an idea to consider?

perryinva

The problem is that the bearing location and design does not really allow a reliable flow of oil, which is why Porsche went with the sealed grease bearing. As many have proven (more than have failed), if the seal stays intact, and the grease within the bearing, 100k miles is not a problem. So along your lines of thinking though, I always wondered if there wasn't a better, more robust REALLY sealed greased bearing instead. If the seal was so good that integrity was never a problem, then problem solved. I assume since this obvious solution has never been proffered that it just doesn't exist.
