camshaft bearing

My 03 FE400e started making a strange sound and losing power on my ride home. I had about 12 miles to go and it made it. I took off the valve cover an the bearing on the right end of the cam, 360 000-01, has come apart. The outer race is there, but the balls are gone. I assume they would have gone down around the camchain, is this right? I'm surprised to see no damage inside the valve cover or around the valves. Is there any way to clean this out without tearing the whole engine down? That is beyond my capabilities and money is tight right now, as I am unemployed. Any ideas as to what damage I may be looking at, beyond replacing the bearing? Thanks for any help.

Unless you can retrieve all of the ball bearings and misc. metal, you actually need to do a complete teardown. A single ball bearing may ruin every gear, and rotating part in the low end if it gets left in the engine.

At a minimum, I'd pull the engine, pull both side covers, and flush the engine over a pan with solvent to catch all the bits of metal. When you are satisfied that there is no loose metal or ball bearings still inside of the engine, I'd install a magnetic oil plug, reassemble and reinstall the engine. I'd then fill with oil, and start it (after repairing the cam bearing of course). I'd bring the engine back up to operating temperature, shut it off, and drain the oil. Check the magnetic plug, and refill with oil. Start it ride it for an hour or two, then drain the oil and check the magnet again. After all of that, I would maybe be satisfied that you had flushed the engine, but my first chioce would be a complete teardown, cleaning all the internals, and checking for damage from the loose bearing parts.

Good luck.
 
I think a complete teardown would be in order or you will never know if everything is retreived untill the next time it fails and really destroys something.......if it already hasnt, i wouldnt run it at all until its sorted or it will only get worse.....or at a minimum listen to brian011952's advise with the flush but at this point you are already so close to complete teardown why stop there?
 
Hi
Brian has a good plan for you, the only thing I would add was, when you open the clutch cover (the other doesn't has nothing for you to check - stator) you can also use a magnet tool to try to access parts of the gearbox side (there are some holes you can use) and try to recover the max bits of metal that you can.
This is assuming that you have all the balls and that you don't have any damages in the engine, wich is very very lucky.
Good luck

you can usually flush it all out with kerosene or diesel fuel. the problem isn't the balls, its the shrapnel from the bearing retainers if you rode it a long while while it was coming apart. they disintegrate into small pieces that can clog your oil passages such as the oil pressure bypass which requires a teardown on an '03. wouldn't hurt to do an oil pressure check after the flush. should be 10 psi at minimum iirc.
 
way i've always done it is to drill and tap the oil filter cover to the pipe size of the gage i have (usually 1/8 npt) and temporarily mount the gage. then measure it cold, hot, high revs, low revs. then when done, put a pipe plug in it.
 
goodness there is some well meaning but wrong advice here.

OK let's do this LOGICALLY ok? 8O 8O

there were 7 balls in that bearing.

they will be around the back of the valve springs and in the bottom of the engine but their favourite place is on top of the cam chain guide on the power side. there is a little ledge just above the bolted pivot, prise it back and there'll be 2 or 3 in there. the others will all be in the left cover. if they aren't well then they are in the gearbox but I've not known them to get that far!

again a magnet and a bit of flushing and fishing and you should be OK.

remember - 7

and also make sure the new ones retain their oil seals.

That's good info to know. Can you tell me what you mean by the power side? I looked in the doc and it said to use these bearings: 360 000-01 SKF. 2 x 6201, 1 x 6201c3 - 2RS1 (then remove the outter seal). I thought there were only 2 bearings. Does this mean there should be a seal on inside?
Thanks Taffy

Click to expand...

I wrote that you should REMOVE the seal? well that is old info from years ago and I don't say that nor have I for many years.

'the power side' you numpty is the chain pull on the front side of the engine - that is as opposed to the slack side on the back run where the tension is kept taught with a tensioner.

you WILL need a strong flat bladed screwdriver to get the blade back for viewing.

there are only two bearings. I believe you were being given a choice....
