I have cross bolt mains 1,2,3,4,5 and I need to check #1 but the oil pump is in the way of the side bolt and factory steering box limits oil pump removal.I think I can drop the pump 1/2" to loosen the side bolt and then the main stud to check if the bearing is still tight after that.

I have removed the oil pump before with the engine in the car. I can't remember the exact proscess, but I think I had to jack up the drivers side of the motor, and then back out the bolts but leave them in the pump.

If I remember right, when I removed the pump to install a high volume kit , I removed the pump cover first, then the body and rotor and installed in the reverse order, didn't have to jack the engine.
Joe BINGO! I just did that,Thank you.Now I have a clear shot at it all.

Well it is looking like I rolled an oil ring putting it together,The main,rod bearings look perfect[almost,lol] on #1main,rod.The squeak is coming from #1 it sounds like and I could pull that head but if you have an idea to test let me know.

I know some of you will say just pull the darn engine but I take this as a learning exercise,opportunity Yep a lesson in why you did not pull the engine! but I am guessing you already figured it would have been easier to do that. Doing an in line re-build should only be reserved for a big diesel engine or something that runs on NITRO

Well I need a line hone,the top half of the bearing is black on 2/3 of it on a 3/4 groove bearing and by the tab is ok.So now we know and thanks for listening.

There is a high spot at the oil hole and a mark on the back of the bearing from the raised spot so I am sure the others are like that.I had the same issue with the cam bearings!!!!!

Did it feel tight when rotated by hand? Doug Yes it was tight turning the crank with no rods or pistons in it so Yes I screwed up by going ahead.I should be able to get it line honed and get things moving smoothly.I hope the other mains did not mess up the crank so it can just be polished.Wait and see how things work out I can use these to help maybe.What do you think? https://www.summitracing.com/parts/slp-142m1/overview/make/chrysler

would hold off buying any parts untill the machine work is done,then discuss it with your machinist.

So this raised spot that every main has by the oil hole, is this from machining/drilling the oil holes/galleries on the mains, almost like a burr? If so you might not need an align hone, hitting each with a radius'd small hone and working them out by hand might suffice. Id think bad main alignment would've even should up with the looser clearances? You take away .001 to .0015" and now it's to tight? I'd get rid of the burrs (if that's what they are), polish the snot out of the crank and get your .004" bearing clearance back.

Maybe some dye on the area and rub a bearing across it to check or partial bearing with emery cloth lightly.The oil hole is drilled from the crank to the cam so why it is raised idk. ps:the bearing is black for 3/4" on both sides of the oil hole with some along the 3/4 groove on the trailing edge.[fyi]

Thank you for your help on this Everyone!!!Roush did the machine work on the as cast block and as in the past with the oil hole in the cam it is high so if it was honed it did not take it out.I set the thrust after I tq'd the mains.I only did a quick check on the crank and the shop that balanced it I guess never looked.[not that I asked]I will go over it better now[a little late I know] ps: the killer is I asked the engine shop that honed the block to align hone it and they did not want to.[long story]

What the heck!?I have it down to the crank with pistons in and it only takes 28 ft lbs to turn it.I noticed it after removing the cam timing chain.I need to hold up here and ponder this.This does not change that the bearing is burned!!!

1 of the 1st things to do is put the #1 main on and see if it is tight again.I noticed something else,The TC nose has the paint off of it and I wonder if the trans is pushing on the crank making the thrust tight in turn making the engine hard to turn by hand.I will get to checking the thrust bearing and the back of it after checking the engine good.I am open for ideas on the order to check things!!!!

Some good news is all the rods,pistonbores look good.1,2,3 main have just a littler heat in them on the block side and not over the oil hole.I will have the crank measured to start and to be honest I think the .001 under bearings will do the trick but we will see. Thanks for listening.ttyl ps:The thrust was .006 with a dial on it.

The main bearing should measure 2.750 correct?I have used the gauge on the piston bore but not the main.

The bearing # is MB5116HP.001 The tech on the phone said the main over bore will take a couple of thou.[crush] and to just watch for fretting on the back of the bearing when going big.

Can't beat the cost of an eagle crank. The first thing to do with them is take them to a good grinder and have them turned .01/.01. I still have a chance to mess it up.
