I doubt their 225-percent markup from LN's price is Luke's doing. Wonder how much they're charging for a Solution? I think I'll ask Luke. I heard slapping the forehead improves circulation.

Luke from Sunset texted me with an answer this morning:

The IMS Solution parts kit is
$4412.82 and we will need to
order it in for you.

That's more than I paid for the engine itself.

This Luke probably wants to make sure and install two of these into your engine. The rest must be the price for ordering.

I'm curious... and correct me if I'm wrong... but...

Are you considering putting in the OEM bearing... and isn't that the part (OEM) that is subject to failure?

As an aside... is Sunset ripping people off? The unsuspecting ones?

No, I"m not, and yes, it is. I'm probably going to cough up $999 for LN's ceramic-hybrid bearing, which is supposed to be a significant improvement over the OEM steel bearing, although LN has a $100 coupon available to purchasers of their Retrofit bearings, so I can get it for $899.

You be the judge. LN's price for their IMS Solution: $1899. Sunset Porsche Parts' price for LN's IMS Solution: $4412.82

Grant, I understand you installed one of these after removing its seals, correct?

[LoneWolfGal]

This might be a naive question, but I have yet to come across an answer: Since double-row bearings are much more reliable than their single-row counterparts, can a single-row bearing and spacer be replaced with a double-row bearing?

No, not with the factory width dual row as the two IMS shafts were different and required different size bearings. LN does have a dual row hybrid replacement for the factory single row which uses offset ball placements to keep the overall size the same as the single row so it will fit the shaft correctly. This LN product does require some specialized tooling for the installation however.

Double D'OH!

Yes. One only removes the outer (rear) seal. This resolves one of the problems with the original bearing... the seal leaking enough to wash the grease out of the bearing but not enough to allow oil back in. Fuller explanations are available elsewhere.

So it's the outer part of the bearing that's exposed to oil and not the inner part? That's counterintuitive to me, but I have yet to remove the bearing from the new engine.

In fact, both sides are exposed, but the inner meets used/trapped oil within the shaft, while the outer side gets relatively fresh oil from the sump. In that sense it's better to remove the outer seal. On the other hand, if you remove both seals (obviously this can only be done if you extract the bearing and install a new one) the oil can go freely through the bearing and won't get trapped in there.

This is a great replacement for the factory dual row, because it's essentially the same, and IMHO is a better design than the hybrid replacements. But it won't work for the IMS that's designed for the single row bearing because simply there's no room for that. So, most of the 2.7 and 3.2 5-chain Boxsters are out. And, you can't swap the IMS either because the chain sprocket is different.

Another that is a challenge on this othervise a very good bearing is, that I have not yet seen anyplace you could order the lockign ring belonging to the bearing groove (pr snapring) to keep the bearing in place - or have I just missed it?
The info I got is that the snapring should not be re-used.

There was no damage on it when I pulled it out so I didn't see any risk of just re-using it.

I did the same thing.

Someone else can comment on that bolt, but I always have the engine mount bolted to the engine. If I need to attach to it, I run a nylon strap (scrap seat belt) around the frame of the mount and chain onto that.

I think I'll follow your lead and bolt the engine-mounting bracket to the engine before installing it. Thanks for the idea. In any case, there's a good chance I'll end up at least replacing the motor mount's bushing, since rubber deteriorates over time. While I'm at it, I might as well also replace the manual transmission's mounts, for the same reason. I want my 986 to be as vibration-free as possible. I once rode in one that almost vibrated the fillings out of my teeth.

7 pm addition: After reading about the travails of pressing a new rubber bushing into an existing engine mount, I think I'll just save time and grief by buying a whole new mount with bushing already installed, seeing as how they're fairly reasonably priced.
