154 Engine overhaul

[cadencewildbeast]

I would probably inspect and test the old springs to see if they are okay. I don't know if the specs are different for the rotator springs, but the regular ones have a free length of 1-31/32 and it takes 23# to compress to 1-1/4.

Thanks for the specs but I really don’t have a way to test the old ones witch is the reason I just spent the money in the new ones. Really didn’t want to spend the kind of money I am on this rebuild to have a spring wear out ans break and send me into another overhaul.

Well then, you've answered your own question.

rotator stuff last time I looked was NA

Thanks for the help. Sounds like I’ll just have to reuse the old ones for the exhaust.

or use all the parts for a normal setup,

That is crazy, since it seems as all the late model stuff (my 68 included) has rotators!

Next problem.... I seam to have a stuck oil pressure relief valve. I am replacing the spring and the plug at the end will not come out of the block. And body got a suggestion on how to get that to come out?

Thanks Bob. I would never have thought of that. Pretty sure machine shop didn’t take it out when they got tanked so afraid their might be some rust in there.

Yet another simple one here. Starting to get things out back together and in my gasket kit from H-Bobs are 2 rubber o-rings that are not listed in their description of the full gasket kit. Are those for the hydraulic pump or something sled that I am not aware of. I haven’t came across any o-rings during tear down. Thanks.

There are two same size o-rings where the hydraulic manifold connects to the pump. Those usually aren't in an engine gasket kit that I know of. What's their OD measurement?

Thanks Bob. That would make since for the F-Cubs. Might have to keep them for my dads machine. They measure right around .850 in OD

I measured the same for the hydraulic manifold o-rings. In looking at HamiltonBob's site, the only pair I see in the full gasket set are the brass ones for the valve cover bolts. I doubt that they would substitute rubber for brass though. ????

Thanks again Bob. I believe I just got a bonus pair of O-rings. I have all the other gaskets that should come in the kit but just also had those so that is what had me wondering. Happy to have more that are not needed than be missing one or 2.

Getting real close to first start on this project. Getting to the point here final checks and fluids are going in. I just added engine oil and I am wondering how long to run the break in oil in it, and if there is a break in procedure anyone recommends. I have Lucas Oil 30 weight break in oil in it. I though I seen somewhere it said about 2 hours?
