ONLY remove the outer bolts that hold the pulley onto the crank snout. One more thing, you'll need to remove the crank pulley to get the new belt on. Start to finish to replace the belt and bent pushrods, adjust the valves and start it up was about 1 1/2 hours. Just did a four cylinder version of this same engine yesterday. The pushrods are the weakest link, and they'll likely be bent. One huge caveat though, if your belt broke WHILE the engine was running, the valves WILL have hit the pistons. The pins are then removed, and the engine is turned over a couple of revolutions by hand.and the timing is checked again. Once the crank and cam are in the proper position, the belt can be put on and tensioned with the offset idler. It doesn't fit into a machined hole in the crankshaft like the other pin holding the camshaft does, it touches against the crankshaft when the crank is in the proper position. The other pin goes on the opposite side of the block near the front. (There are threaded plugs for both of the timing pin holes that take a 10 mm socket to remove.) It threads into the hole once the camshaft is turned into its proper position. One of the pins goes into a hole near the rear of the engine block, on the side. To properly time these engines, you should buy or rent the timing pins.look on eBay by entering keywords like "Deutz timing pins". Diesel oil is black enough already, but when it gets into the cylinder and is partially ignited, it gets really messy and difficult to remove from nearby vehicles, windows, buildings, etc.) The oil that's going through the cylinders is getting *burned* a bit before it gets expelled from the exhaust. (Don't run the engine near anything until you get it fixed.
Installing the proper one is essential because the piston's protrusion above the block deck is compensated for by the proper gasket. There are three different thickness head gaskets available for your engine. They're identified by counting the notches in the corner of the gasket itself. When you go to buy a replacement gasket, you'll need to take note of which gasket you need. We've replaced a few Deutz head gaskets on the 3 and 4 cylinder versions of this engine. The reason you see "raw oil" coming out of your exhaust, is that oil under pressure is being pushed into the cylinder through the blown part of the gasket whenever the engine's stroke position allows oil pressure to overcome internal cylinder pressure. The engine oil that's being pumped throughout your engine, is being pumped at whatever the engine's oil pressure is. One big difference between more conventional cooling systems and the Deutz, is the coolant's pressure. Like a more conventional cooling system that uses an antifreeze solution, the *coolant* is pumped around through the engine's coolant passages and then through a heat exchanger.then back through the engine again. There's a coolant jacket that surrounds the upper area of the engine cylinders, and passages exist for cooling oil to flow around inside the cylinder head also. The Deutz engines like yours use engine oil for coolant.
Your engine likely has a blown head gasket.
