Helping Waterloo out with an inframe ...

Can you elaborate on the oil and stone on the block? I'm assuming that is to prep the deck for the head gasket and to make sure it's flat. What grit stone are you using for the proper RA on the deck and where in the world did you get a stone that big and flat?

Did your engine have the updated retainer on the cam? The thicker washer that goes under the bolt that is supposed to be more resistant to breaking? I keep hearing of an improved one, haven't seen one yet, or a part number. Want to make sure I have one on hand when the time comes.

Did you guys pull the front structure? I'm still trying to get eyes on this, to see what that entails. When I do mine this summer, I want to reseal that.

The ifsm, is there a master o ring kit that comes with the rebuild kit? I want to say there is a screen and a few other parts that need attention besides the pumps and actuators, didn't know if these came with the inframe kit from Cummins or not.

I'm still out running. I have been thinking of dropping by on my 34, but it now looks like I have an injector or something on it's way out on my truck. Idles like ass and drinks fuel. It's always something!

Those bowls are a great idea. Still envious of what you are learning. I bet it'll feel great when you drive it again!

That stone is just a small flat one, say 3.5-4" long, 1/4" thick, 1.5 inches wide. Looks to be regular cutting oil that Rawze uses for the first round, and then for finishing a mix of acetone and transmission fluid. As far as the stone grit, I am going to say around 800 or there about.

The retainer on the cam, it was what came on the motor from the factory. 2007 build date on this particular CM-871. I'll ask Mr Hagg if I remember, see if he knows or has heard anything. He has three ISX's in the shop being overhauled right now and more waiting in the wings. Mr Hagg orders more rebuild kits than anyone in the state if I heard correctly the other day. If anyone knows, it will be him.

The front structure? Are you asking about the structure that holds the gears or the front structure that holds the CAC and radiator? The structure that holds the gears was left on, we simply removed the front cover to get to the cams, and lifted the head out at an angle with the crane. The actual front structure that holds the CAC and radiator is held on with two bolts under the frame. We removed the entire unit in one piece with the crane. That has to be removed, as that is the only way to remove the cams.

As far as the IFSM, like Signature stated, the gasket is what comes in the kit. Mr Hagg is putting together some other parts he believes I will need. I'll see what other extras we will be getting, and you are the second person to mention the IFSM, I will look into that and more than likely order those parts. I know I will need an AC o-ring kit, need to order that too.

Yes on driving it again, but still much work to be done, this is not an easy job. Not something I would attempt in my driveway just yet, I would want a shop to do this in.
