Resolved Do camshaft bearings exist?

[squid267]

Hey, my mechanic told me to get camshaft bearings, but i havent been able to find them anywhere. Do they exist?

I read this thread, http://www.dsmtuners.com/forums/cyl...ely-ability-6-bolt-rebuild.html#post151343234

it looks there just the journal and then the camshaft on top of it. correct me if im wrong. Thanks!

There are no cam bearings on these engines. Like you said, they just sit in a machined journal.

Thanks much appreciated!

Maybe he said CRANKshaft bearings?

You are correct, camshaft rides on a journal

Some cars still use them..my buddy spun 2 of 4 cam bearings on his 96 civic. Freakin' thing ran for 3 months like that..and the kid beat the piss out of it during that 3 months too. Only a honda...

Agreed. Doesn't sound like a mechanic I would trust to work on a DSM.

And FYI- Since the cams do not use bearings, it is important that the cam journals are free of damage and that the cam caps are put on in the correct order/direction. So if he did any work on the engine, make sure to double check that.

The only other thing related to the cam shaft rotating assembly is the cam seals. They may need to be replaced whenever the cam shafts are removed.

DSM camshaft bearings are on the shelf next to the muffler bearings and blinker fluid I was all set to purchase a used head once, and saw that one of the cam caps was jacked up... be sure to always put them in the correct position where they were removed from and facing the correct direction. The jacked up head I looked at was messed up from putting one of the caps on backwards and tightening it down. He didn't even run it that way, but it distorted the cap.

im rebuilding my buddys 95 gdst six bolt swap with 20 g turbo and there is no babbit left on the cam journals and im wondering whether or not I have to replace the cylinder head or take it to a machine shop he has 272 cams and titanium valve springs and don't want to destroy his pretty new 500 cams with the exposed aluminum on the cam journals but im kinda stuck knowing that the cams ride on a thin film of oil and the wear is not catastrophic just the shiny babbit alloy is removed on a lot of these journals

The cams ride on the aluminum journal.

No babbit on the cam journals.

No cam bearings for a 4g63 cam

The cams run right on the head casting.

The Mitsu 4g63 is not a Ford 2.3 that has cam bearings.

96 Honda engines do not have cam bearings.
