A cam bearing removal and and installing tool is the proper way to get these bearings removed and replaced without damage to the block or the new bearings. Cam bearings can be very "soft" and will distort if not inserted square with the bore and the oil holes need to be aligned properly. Almost any garage or automotive machine shop will have this tool,and can do this for a very minimal fee.

NAPA sells the KD tool kit for performing this job. Check with any good auto parts store and they will be able to order one up. The kit is not cheap. Also check Summit.

Unless you have done this before, and have the tools, take it to a shop for that process. Most will do it super cheap, esp if you have them clean the block. A couple shops here if you pay them for cleaning, they'll do the bearing remove and install for free or for a $20.
They did my bearings for much less than the cost of the tool. (although I HAVE done it before, I no longer have the tool for it) Don't try it without the correct tools, a mistake can be very costly. And if you don't get them in straight or lined up with the oiling holes, wow, what a bad thing. |

Best thing to do take it to a machine shop and have them put new cam bearings---why do it the hard way?

If you find the right guy, we even had a young guy in town who would drive out to the shop and knock them out and a new set in for us.
I think he charged like $40 for the road trip, labor, we supplied the bearings.(dealership, long story) If your going to do it, you might as well just get the shop to do the clean and new bearings. Saves you time and effort and if it's a stock bore block you can have it honed and checked ready to go when you get it back. Never hurts to scrub it out one last time before assembly though! |

i honed the cylinders myself last night. it went really well. they look really good.
i may just build my own tool to do it myself. i don't like the idea of pounding the bearings in. i think some lube and pressure would seat the bearings better. just my opinion though. i would have just used the stock bearings, but they are all broken. they literally split apart when i removed the cam. i ordered new bearings from summit and the summit 8600 cam while i was at it. it came out to $95 with shipping. this motor is going in a jeep wagoneer, so i'm looking for some better low end torque. are there any instructions anywhere for installing this cam? how is it supposed to be degree'd? i'm just looking for some reading material before i start the process. this is my first engine rebuild, i'm really enjoying it so far. |

Did you force the cam out?????? if you did, then that is why your cam bearings are broken.......I would not put the new cam in the same way--you will break the new bearings the same way..................You are supposed to turn the cam as you take it out.........................

My guess is you broke the glaze...... using a standard parts store glazebreaker. Proper honing takes the right equipment and the correct grit for the type of rings you intend on using. You'd use a different surface for moly rings as opposed to cast, for example. If the surface is "too slick" the moly rings will take FOREVER to seat. Did you measure the out of round, taper, etc.? Is there any ridge left at all? If you can even slightly 'catch a fingernail' on it............... |
