Here I go caveman-ing it again. With the cover face up I stuck a 35mm impact socket into the hole, and smacked it out with the sledge hammer. Did I mention I really need to get a shop press? LOL! What can I say, I'm such a Stooge. Image Unavailable, Please Login Image Unavailable, Please Login
With the pulley bearing out of the cover it exposed at o-ring inside that needs to be replaced. I carefully removed the o-ring using a pick. Image Unavailable, Please Login
Now for a side by side. This is the front of the bearings. Old one on the left and new one on the right. Image Unavailable, Please Login
And the back of the bearings. The new one has a seal on the back, where the old one doesn't. Image Unavailable, Please Login
There wasn't a manufacture name on the new bearing, only these numbers. 170787 Image Unavailable, Please Login
Before I installed the new bearing, I fitted the ring clip to the groove on the front side of the cover. Image Unavailable, Please Login
They are known to be overfilled with grease, and the seal fitment is very inconsistent. They can throw grease within 10 minutes, 10 days, or 10 weeks --- but I have yet to find one that is actually as good as the original SKF. Whoever is manufacturing them (it is not SKF, Timkin, NSK, etc from what we can determined) is doing so under contract from Ferrari and stamping a Ferrari part number onto it (170787), but ignoring all the other BICC conventions on product labeling, and presumably QC
AH HA! Thanks for the heads up Daniel-San! And good looking out! But it's already too late. The bearing has already been installed. Guess I'll be the guinea pig and see what happens. Hopefully I'll get lucky. It's not that I'm ignoring Daniel's warning, it's that it really is already too late. All these posts are all after the fact. The belt is already on the engine and everything has been timed. SO it really is too late. I'd have to tear it all down again and I'm not gonna do that. If the bearing bites the dust, I have to tear it all down. If I head Daniel's warning, I have to tear it all down again. Either way it will have to get torn down, AGAIN. So SCREW IT, the Stooge in me will roll the dice and see what happens.
I have struggled heroically with Hill Engineering on this one. Hill has a bespoke design, but it has been held up in a legal fight over T&C with the core manufacturer. Maybe somebody else has a quality replacement (in lieu of the Hill eventually getting released -- but we're going on over 1 year now ). But it ain't me. We pulled the 170787 from our shelf and literally threw them into the dumpster. Luckily, they're not very expensive.
Okay lets get back to putting this thing back together, after SOMEONE was a party pooper. Hahahahaha!!! I'm ONLY KIDDING Daniel-San!
Now to install the new mystery bearing into the cam cover. "WARNING, WARNING, DANGER WILL ROBINSON!" I turned the cover over and set the bearing into the hole as even as I could. Image Unavailable, Please Login
It's already back together Tim. I mean the bearings, the cover, the bottom sump pan, the water pump, cam belt bearing, cam belt, and the timing has been set. It's already finished. If I have to open it back up I WILL be keeping this bearing in mind!
Ok so I then gently tap the mystery bearing into the cover, but NOT all the way in. Image Unavailable, Please Login
I stop just before the front of the bearing gets to the grove for the o-ring. I'm pointing to the groove with the tip of the pick. Image Unavailable, Please Login
Then the mystery bearing gets finished being tapped into the cover. Now the shim gets centered over the outer race of the bearing. Image Unavailable, Please Login
I fitted the snap ring, but not all the way. I only inserted it on the inner rim of the cover. See the shim is not an exact fit and moved around while I was trying to get the snap ring installed. So the snap ring got installed on the inner diameter of the bearing hole in the cover, just about the shim. Image Unavailable, Please Login
Then I set the widest socket I could fit in the hole, made sure the shim was still centered, and sharply pushed the snap ring down, setting it in the cover. Image Unavailable, Please Login Image Unavailable, Please Login
And here we have the new mystery bearing locked in place ready for work. Thanks again for the heads up Daniel, and the suggestion Tim. Guess we'll find out how well this bearing holds up. Image Unavailable, Please Login
Now to reinstall the timing chain cover. After making sure the surface of the cover is clean, and the mounting surface on the block is clean, and oil free, .. I apply some Hondabond to the cover. The set the gasket on the cover and smear some more Hondabond to the seal. Image Unavailable, Please Login Image Unavailable, Please Login
