21887815 Volvo.Penta Breather pipe

TYPICAL EXAMPLE1. Turn the crankshaft until the timing mark on the crankshaft gear (1) is in alignment with the timing mark on camshaft gear (2).2. Make a mark on the teeth of the fuel pump drive gear and the idler gear in their engaged position at location (A). Mark the engaged teeth of idler gear and camshaft gear at location (B). This will give assistance in the correct timing of the camshaft for the fuel injection pump during crankshaft installation. 3. Fasten a hoist to the crankshaft.4. Remove the caps for the main bearings.5. Remove the crankshaft. Weight of the crankshaft is 95 kg (210 lb.).6. Remove the crankshaft main bearings from the cylinder block and from the caps.Install Crankshaft
1. Clean the surfaces on the cylinder block for the bearings. Install the upper halves of the main bearings in the block. Put clean oil on the bearings.2. Put the crankshaft in the block with a hoist. Be sure all timing marks are in alignment.3. Clean the main bearing caps. Install the lower halves of the main bearings in the caps. 4. Check the main bearing clearance with plastigage (A). Install the caps in their correct places. Be sure the number on the cap is toward the number on the pan surface on the left side of the block.5. Put 2P2506 Thread Lubricant on the threads of the bolts and on the faces of the washers that hold the main bearing caps. Install the bolts and washers. Tighten bolt bolts to 40 4 N m (30 3 lb. ft.). Put a mark on the bolt heads and bearing caps. Tighten the bolts 90° from the mark as shown. Remove bearing caps and measure the thickness of the plastigage (A). Main bearing clearance (plastigage thickness) must be 0.074 to 0.165 mm (.0029 to .0065 in.). Maximum permissible clearance is .025 mm (.010 in.). 6. Put clean oil in the lower halves of main bearings. Install the caps in their correct places. Install the bolts and washers. Tighten to 40.7 4.1 N m (30 3 lb. ft.). Put marks on bolt heads and caps. Tighten each bolt 90° from the mark. 7. Check the crankshaft end clearance with tool group (B). End clearance is controlled by the thrust bearing (1) on the rear main. End clearance must be 0.064 to 0.368 mm (.0025 to .0145 in.). Maximum permissible end clearance is 0.64 mm (.025 in.).8. If the accessory drive gear, idler gear, camshaft gear or crankshaft gear has been removed or replaced it is necessary to put the accessory drive shaft into correct timing after the engine is assembled.

start by:a) remove valve liftersb) remove timing gear cover 1. Bend lock (tabs) (2) and remove bolts (1).2. Turn the crankshaft until the "C" mark on the crankshaft gear is in alignment with the "C" mark on the camshaft gear. To keep the engine timing correct during removal and installation of the camshaft, put a mark on the teeth of the idler gear, camshaft gear (3) and fuel injection pump drive gear locations (A).3. Remove the camshaft and gear. Do not cause damage to the lobes or bearings when the camshaft is removed.4. Remove the bolts that hold the camshaft gear to the camshaft. Remove the camshaft gear (3).Install Camshaft
1. Install the camshaft drive gear on the end of the camshaft. Put clean SAE 30 oil on the lobes and bearing journals of the camshaft.
Do not cause damage to the lobes or bearing journals when the camshaft is removed.
TYPICAL EXAMPLE2. Make an alignment of the "C" marks and marks put on during removal. Install camshaft (1) in the cylinder block. 3. Install thrust washer (3), lock (2) and the bolts that hold the camshaft in place.end by:a) install valve liftersb) install timing gear cover
