CASE 580B CK FUEL TIMING ISSUES

[nickakacowboy8]

Hello, I currently have a 1971 case 580B CK that we did an engine swap on. We are having a hard time getting to start. It was a incomplete long block, had to swap flywheel and complete front gear train and injection pump. We have set the engine at 8* BTC and lined the lines up in the window on the injection pump. We get smoke out of the exhaust but it will not even try and fire. My question is it possible to install the flywheel incorrectly? Any help with this would be greatly appreciated.

The flywheel on most all engines i evever worked on has only one way the bolts will all go on ,,..if , this engine ran before , it should run again ? perhaps you are pulling in air ?

Have good fuel at all nozzles, not sure if engine ran, it was a reman from back east somewhere, (I'm on the west coast). I had one of my
guy's put the flywheel on and install engine into backhoe. What makes me wonder is with the timing marks at 8* the exhaust valve is open on
cylinder #1 and looking at the old engine there doesn't appear to be any locating dowels or bolt holes misaligned

Sounds like you are 1 revolution off. You are 8BTC #4

So that means the flywheel could be put on wrong, what would be the easiest way to go about getting the timing right with out pulling the engine back out and reinstalling the flywheel.

Pump AND camshaft turn at 1/2 engine speed. With the valve cover off the valves on number four cylinder should be rocking when crank is at pistons one and four are at TDC, this will verify number ONE is on compression stroke ready to fire. Injection pump timing mark SHOULD be in the window at this time, if not pump is off 1/2 turn.The CAMSHAFT determines which cylinder is ready to fire, and the pump MUST match it.

The flywheel bolts only fit one way, the holes are NOT evenly spaced, unless someone really messed up and left bolts out it is on correctly.

I do not think you can put the flywheel on wrong unless you leave a couple bolts out. jmho gobble

You posted ''What makes me wonder is with the timing marks at 8* the exhaust valve is open on cylinder #1''.

I'm with John Saeli and Dieseltech. It very much sounds like #4 TDC was in the firing position when the pump was installed, not #1 cylinder. #1 and #4 are TDC at the same time the marks on the flywheel line up. To be on the firing stroke both valves on #1 need to be closed, both have clearance at the rockers, and the valves on #4 will be ''on the rock'' (exhaust valve just closing and the intake valve starting to open, little to no clearance if you try to move the rockers). If the exhaust valve on #1 is open at 8 degrees before TDC, that tells me it is about to close as it just finishing the exhaust stroke and will be starting to open the intake valve at TDC for the intake stroke. That means #4 is ready to fire at that point, making your pump timing 180 degrees out. Turn, in the direction it runs, the engine one full turn until the 8 Degree mark lines up. #4 cylinder's valves should be on the rock if you look at them and #1 valves closed., then install the pump.

I hate when that happens, hard enough to eyeball the timing marks on the flywheel nevermind doing it twice.

So found out something huge today trouble shooting this darn thing. My mechanic used the bell housing bolts to mate up the engine to the transmission, in doing so the flywheel broke. Now I know why the timing was off every time we tried to start it. Does anyone know of anyone that has a flywheel for sale, it's a 1971 580b CK PowerShuddle.

I have one Give me a call at 740-992-two 128 any time. It's still in the parts backhoe so engine would have to be removed.
