Default Killer Dowel repair

I have to make this repair to my engine.I have done a fair bit of research about the repair.I have accumulated all the parts except for the gear housing.My housing cracked from the dowel coming out.I am wondering if there is a way to remove the push rods without removing the rocker pedestals?Next, I would like to know what size of doweling will work for holding the tappets up to remove the cam?I have gotten info from the internet,1995 Dodge service manual and advice from a Cummins service advisor.Additional help would be welcome.Thanks.

Thanks for the info.Must the oil pump come off.I was under the impression that the gear housing cover can be removed without taking the oil pump off??

to tell you the truth chucks i am not sure about that are you going to have your front cover welded or are you going to try and find one i heard on here they can be hard to find and quite expensive and they have had pretty good luck with welding them with the right welder

the oil pump doesn't have to come off, it'll fit back thru the case. you can use 1/2" dowel rods and you bevel the end to fit down into the tappet. tap em down in lift the tappets off the cam n pull the cam out. put a piece of pvc pipe in place of the cam just in case any of your tappets fall, they wont go clear to the oil pan. n when my pin went thru the case, i took it to the welding teacher down at college n he welded it n i haven't had a drop of oil leak past yet.

Isnt it easier just to pull the cam gear? Or Is it easier to just pull the cam out? I have heard both ways.

Don't pull the cam gear. That requires heating of the gear and if you heat the gear you are just asking to break it not to mention you would have a hell of a time reinstalling the gear without driving the feeze plug out of the block.

I have a gear housing coming from an auto wrecker.I did show a machine shop the general location of the crack from a parts picture, but without it off,a proper estimate for the repair couldn't be given.I wanted to have all the parts before I tackled the job.Once mine is off,I can get it looked at by the machinist and maybe I will be able to help some one else with a replacement.After it is welded of course.Cummins95,What size of PVC pipe is recommended??Sounds like a good precaution.Thanks for all the additional info.
