| Post subject: | crankshaft removal |
1965 d100 225 engine on engine stand. engine rotated on engine stand to allow pan removed and displaying rotating assembly upward for ease of work. I have done this on "other manufacturers engines" by simply removing timing chain and removing rod and main caps. I ask this question in hypothetical for a soon decision to be made by me to, utilize a different engine or continue with this one. I have no intention to disassemble head, pistons etc. So, here is my question,..... Can the crankshaft be easily removed at the juncture described in the first paragraph above ? |

Just like Doc said with the main caps, rod caps, and rear main seal removed it should lift right out with a tug...that being said easy isn't the first word I'd use on an early forged crank as the thing weighs more than the late forged cranks and any cast crank...make sure you use both hands, plant your feet and don't twist your back. -D.Idiot |

Engine Background,.. only 65000 miles on one owner truck. I put a 79 head on it so,.. 1500 miles later I started to hear a slight thunking noise. it was different sounding than a rod going out. So then I watched the oil pressure under acceleration for main bearings and it held stable. So I decided to have a look see. Due to it being a "thunk" and unlike a "rod sound knock" I yet admit to being unsure. Pretty cold out today in the gravel pit. I hope to examine either today or tomorrow. The question about crank removal was for my options. I am looking to that area first. due to knowing " knocking rod sounds" from my hot rod youth,... Right now I am downright curious |

"Exploratory surgery"... fair enough. Let us know what you find. As an FYI, I have some .001 & .002 under main bearings if you find some badly worn mains. DD |

Hey Doc, Sounds as if you are stocked up on undersize main bearings,... hmm,. that makes me think,.. Lol I am anxious to see. It may be just a short while to respond, but is surely will. I am pushing 80 yrs. Plus it is still cold in my environment. Gordo |

Well, I did get back to it today. After micing the rod journals I could use some undersize bearings I am looking for one thousands undersize rod bearings. the ones in it were Clevite 55 CB 606 G I went to my local Napa and they told me that the CB 606 was a undersize one thousands. !! I say they are full of "Bog Fooey" I believe CB 606 G is standard size,.? What say you,?,... and where do I purchase one thousands undersize rod bearings.? Gordo |

Yes, and these lack that. Bad news is they no longer make a .001 undersize. So,.. either grind the crank to .010 or put a V/8 in it. Lest someone knows where I can purchase .001's |
