Yes. The thickness of the adaptor compensates for the length of the cam. |

Re: 59 AB engine rebuild
I finally got one of the valves out.
Thanks to everyone's help. The camshaft does not rotate I think some of the lifters Are stuck. How can I go about removing the valves that are in the Open position? |

Re: 59 AB engine rebuild
Try this, if the valve is open, turn engine on stand with valve pocket facing up, pour a small(capful) amount of your favorite flammamable product, I used denatured alcohol, then light it. Let it burn completely out then go in with your valve fork and try to move the guide. The direction you move it will depend on wether the "C" clip is still holding guide.
I'm tearing apart a 1940 block now and all the exhaust guides are stuck. P.S. Do this in an open area, and keep a fire ext handy. |

Re: 59 AB engine rebuild
Unless you are wanting to save the valve and springs for some reason the best method is to cut them. You will be forever trying to take it apart otherwise. A cut-off wheel works as do other instruments of destruction. That's just the nature of the beast with an engine that is completely curded up and even at that it is a major job getting the guides out. You will be far better off replacing the valves and spring and guides on an engine in this condition.

Re: 59 AB engine rebuild
We talked about full floating bearings above and that was the main reason for my post. I was surprised they fit so easily. Or, am I missing something?

Nope, just thought you might get more noticed on a new thread, if you like it here great.

Re: 59 AB engine rebuild
Hi Larry, just an important tip to others here doing any assembling on ANY build, doesn't matter the mfr, the very first item to check is to make certain the cam fits the newly installed cam brgs, this is done first!!
When we do the cam brgs here we always try a cam for fit BEFORE the job is delivered and the customer finds the issue. We have almost all brands (mfr's) of cams to work with, we tape up ALL the lobes and any gears and try it for fit! There is nothing worse than a customer calling and saying "I can't get the cam in OR I can't turn it when it goes in", this is very frustrating to the assembler. And this is why I say this should be the very first checkpoint. Too many assemblers go ahead and install the crank, rods, and pistons first and then "hit" the panic button when it's the cams turn! Having it all together makes a "cam-brg-repair" that much more difficult. Thanks, Gary in N.Y. P.S. I'm curious if you "honed" directly on the cam brgs OR the cam brg holes in the block?? You cannot "hone" babbited material, the grit WILL embed it self in there!

Re: 59 AB engine rebuild
I was hoping to reuse these valves if I can.
The only way I have been able to get the keepers to drop out is to lift the valve up with the bar "pickle fork tool" and place a piece of wood on top of the valve and hit it down with a hammer. Hoping this method is ok. |

Re: 59 AB engine rebuild
I know not to hone Babbitt, but did not know what else to do. I've bought bearings for two engines now and both sets of cam bearings were two small. Who makes bearings that fit?

We use only the Durabond line and we have them "Teflon" coated by Calico when the customer requires the coatings. We've been using this procedure since the coatings began. We like it due to the fact most cam-to-journal clearances on this platform are generally on the loose side, hence the coating! Thanks, Gary in N.Y. P.S. I would strongly recommend getting an accurate size on all 3 cam tunnel holes, this is a starting point! The holes should be 1.928" +/- .0005"! Also double check the cam journals, they should be between 1.796"/1.797".

Re: 59 AB engine rebuild
I have been using the Valve spring compressor and think I have gotten the hang of getting these valves out. Only four more to go. Thanks for all the help.

Re: 59 AB engine rebuild
Good luck on your 59A build! I built mine last winter with the help of Ol'Ron's book and many members of the Barn. My 37 is my daily driver and so far no problems. you could probably search my threads and posts to help answer some of your questions. Good Luck!

Ask the shop if they use a block-plate when finish honing the bores?? and see if they are able to pin the heads and gaskets to the block like the SBC's?? Thanks, Gary in N.Y. P.S. Also ask about modifying the block for the 95% oil filtering setup. This is the time to have that done.

Re: 59 AB engine rebuild
What does the block plate do when finish honing the blocks?
And what does pin the heads and gaskets to the block mean? How necessary is the 95% oil filtering setup? |
