Thread: D@mn Cam Bearings Wtf!

Tweet

Well, me and my frend and my brother in law were putting the engine together and every thing went smooth untill the #4 cam bearing. The cam came to a dead stop! So, my frend looked at it and started fvcking with it, and it was tighter then a nuns twat on on sunday. The cam got totally stuck in there! The bearing is screwed. Well So I am going to call the shop that installed them tomorrow and see if that can fix it.

sound like to many helpers. you could of drive it in cocky? i only had a ford 300 6 like that. i had to send it out for in line bore and get the cam housing bore open up. ford used one under size cam bearing in the block. came form ford that way .sounds like you mix them up positons? like ch-1 is #1... ch-2 is#2or5... ch-3is#3or4... the oR means they will need them to go in the posted positions

yeah i didint install the Cam Bearings the shop did. i just hope they can fix it

well i check them with a old cam .if they drive the cam bearing in and hammer the hell out of it then they put a burr on it .this can happen. this is no big deal.. if not beat to $hit just clean the bur off with a bearing scrapper

I have seen that cam bore on the block is undersize and have to machine the OD of the bearing down to make it fit properly. So measure the bore and check in the engine bearing book for Bore size. Those Chrysler are bad about having undersize cam bore. I have seen the bore undersize tight as .005 to .010 too small.

this is a chevy bbc i build my share of bbc chevys only seen one that was on the small side . i just bore the cam bore out were it needs. not the out side shell of the bearings ? but what ever makes you happy . how or why if you do not mind me asking would you go thru all the time to make up a drive mandrill to hold the cam bearing not to spin and trash the finsh were the cam would run in it. then find the center of the bearing with no run out then cut it ? that is how you do it right? i use the ground outer i guess you could do one of that type. but not the rolled butt clench type of cam bearing

well when i couldn't get the cam in my Friend wonted to look at it well he was a little Ruff with the cam and all the bearings are nicked bad now
so what i am asking now is where can i get a tool to install new bearings that is under $50??
i see them on summit and there $200! like any man i love tool but not if there that much!

Let the shop do it ,its about that price,just talk to the guys that did it originally and they should atleast cut you a deal on the new ones and let them know the reason is because the cam was really tight and would not fit.
I would also take my cam with me when I picked the block up and try to install it right then and there so they can see for themselves if it does not fit correctly.
Cam bearings are picky about installation /orientation and thats why the tool is 200 bucks,plus they are no fun to deal with way up inside the block.
The cheapest tool is not the one you want for this job.

they can be pickup from many but not for $50.new i have one i like it works fine it has paid for it self many times over .but there some thing i do to the cam bearings and the bores .i just do not slam then in .so less you build alot of engines or machine alot of blocks you may just want to find a shop to do them for you. there is times when you have to work on them in the block if one as a hi spot but if you have never done any of this it better to pay some one that put the in every week for a liven , i have a machine shop and not one block will go out the door with out me checking it . must be alot of 1/2 ass shops out there. this one of the less hard jobs to do ? but over look by some ???

well the shop i talked 2 wants $100 to due my bearings

The number 4 cam bearing looks way to tight or is it just the picture???

looks like you hit every one with the cam lobes you have to be more careful to hard to see any thing but the dents in the cam bearings. i get $45. to put them in have to raise my rates

wow 100.00 for cam bearings..is that american money? i really need to look at my pricing..i must be stuck in the sixties..sometimes you do have to kinnda work on em (with a broke ring my favorite) to get it right (dang dodges) but that much for a standard install..WOW

I agree with Pat. When you install the cam, you have to be very careful, plenty of thick lub, and rotate the cam as you install it. That may be another reason you think they were not correct. You couldn't get past a point, because you didn't gently rotate the cam, and the cam may not pass past the third bearing unless you do.

You can scratch those bearings with your fingernail. That's how carefull you must be.

yeah i know butt that bearing i think is to small
