Remove the cam cover, remove the spark plugs, turn the engine to number 1 TDC, put a pencil in spark plug hole number one and twist the crank back and forth and make doubly sure you are at TDC. Now loosen the four bolts at the front of each cam sprocket, check TDC again with the pencil and rocking the crank, now take the pencil and lay it across the flats at the back of each cam. Twist the cams very carefully so that the pencil sits flat on each cam square. Snug up the sprocket bolts and use the pencil to check TDC again! Now check the cams again. Repeat the procedure until you have the cams flat and the engine at TDC.

SOURCE: timing mark alignment for 92 bmw 325i 2.5L

your cams have a what looks like a square on them . find it and face them with the dimples on them up. then use a flat edged ruler to make sur you have them right. then turn no.1 cylinder top dead center. then take and put your chain on your exhaust sprocket and point the dimple up do the same with the intake. tighten down the torx bolts and recheck! it took me 3 times but its better than the $300+ tools and car runs great. if need be look up some of the e36 groups on line.

02 ford escape V6 what is positions of the camshaft sprocket timing marks and the crankshaft keyway


The camshaft and Crank mark (key way) should be pointing at each other (directly aligned with each other).
ie. The Camshaft mark will be point directly downward toward the crank and the crank mark (key way) will be pointing directly upward toward the camshaft.

Bmw m42 engine to fit a camshaft sprocket to a camshaft


The M42 and M46 engines have the twin vanos pulleys and require locking tools to lock the crank and cam shafts inot the correct position. There are no timing marks on these as they are floating pulleys- ie they have no key locating the pulley in a specific position on the cam. Unless you make accurate marks during stripping there is very little chance you will be able to get the cam timing right on this engine without the cam locking tool kit.

Bmw m42 engine. The sprockets on the camshafts must be refitted, which way do the arrows point


You must use a special tool which bolts onto the cylinder head. It is designed to hold the camshafts in the proper position. It goes over the flats on the camshafts to hold the camshafts in the correct position. This tool can be rented. Look on EBay or check with your local Snap On Tools, Mac Tools, or Matco Tools dealers to rent one. See the link below for photos of properly aligned timing marks for your engine.

I need a diagram of timing chain replacement Thank You


During most engine rebuilds, a completely new timing assembly should be installed. If wear exists on any component, replacement of the entire assembly is necessary. Wear in the chain, gears, or sprockets means a timing lag, which results in poor engine performance.
The timing chain or belt is generally installed with the gears in their correct positions. Before installing a new chain, soak it in oil.
OHC (Overhead Cam) Engines
Some OHC engines use a chain drive; others use a belt drive. Removing the cover on some OHC engines that have timing chains is more difficult, because the cover often fits between the oil pan and the cylinder head. There are special procedures for replacing cam timing components in these engines.
Before a chain repair job, perform a leakage test on non-freewheeling engines to check for bent valves, so that an accurate repair estimate can be made.
OHV (Overhead Valve) Pushrod Engines
On many OHV pushrod engines, the crankshaft sprocket is installed on the crankshaft nose and the crankshaft is rotated to position piston #1 at TDC. At this point, a mark stamped onto the crankshaft sprocket is pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used to rotate the cam until a mark stamped on the cam sprocket is pointing directly downward (toward the crankshaft). The sprocket is then removed from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam gear is positioned directly downward, and the chain is looped around the crankshaft sprocket. When the cam sprocket is attached to the cam, the timing marks on the crank and cam sprockets should be pointing toward one another. NOTE THIS IS FOR 2WD 4.0

How i fix timing of lantra 1600 cc 95


Disconnect battery earth lead. Do not turn crankshaft or camshaft when timing belt removed. Remove spark plugs to ease turning engine. Turn engine in normal direction of ratation unless otherwise stated, Support engine. Remove, engine mounting, auxilliaty drive belts. Water pump pulley 1. Crankshaft pulley bolts 21. crankshaft pully 2. timing belt covers 3. Turn crankshaft to TDC on No 1 cyclinder. Ensure crankshaft sprocket, camshaft sprocket, oil pump sprocket and balancer shaft sprocket timing marks aligned. Timing marks on camshaft sprockets should align with cylinder head upper face. Dowel pins on camshaft sprockets should face upwards. Slacken tensioner bolt. Move tensioner away from belt and lightly tighten bolt. Remove, automatic tensioner unit bolts. Automatic tensioner unit. Timing belt, crankshaft centre bolt, crankshaft sprocket. Crankshaft sprocket guide washer. Slacken blancer shaft belt tensioner bolt. Move tensioner away from belt and lightly tighten bolt. Remove balancer shaft belt.

Installation
Ensuring timing marks arligned. Note timing marks on camshaft sprockets should align with cylinder head upper face. Exhaust sprocket mark is on recess, but inlet sprocket mark is on tooth. Note: to check oil pump sprocket positioned correctly, removing blanking plug from cylinder block. Insert 8mm diameter Phillips srcrewdriver in hole. Ensure screwdriver is inserted 60mm from face of cylinder block. if screwdriver can only be inserted 20mm: turn oil pump sprocket 360°. Insert screwdriver again. Fit balancer shaft belt in anti-clockwise direction, starting at crankshaft sprocket. Slacken balancer shaft belt tensioner bolt. Turn tensioner clockwise to tension belt. Tighten bolt to 15-22Nm. Apply thumb pressure to belt. Belt should deflect 5-7 mm. If not repeat tensioning procedure. Install crankshaft sprocket guide washer, crnakshaft sprocket. Tighten crankshaft cente bolt. Tighten torque:110-130 Nm. Note ensure crankshaft sprocket guide washer is fitted correclty. Oil treads and contact face of crankshaft body before fitting. Check tensioner body for leakage or damage replace if necessary. Check pushrod protrusion is 12mm. If not replace automatic tensioner unit. Slowly compress pushrod into tensioner body until holes aligned. Resistance should be felt. Place flat washer under tnesioner body to avoid damage to body end plugs. Retain pushrod with suitable pin through hole in tensioner body. install automatic tensioner unit to cylinder block. Tighten bolts to 22-27Nm. Fit timing belt in anti-clockwise direction, starting at the tensioner pulley. Slacken tensioner pulley bolt. Turn tensioner pully clockwise to temporarily tension belt. Tighten bolts to 43-45Nm. Turn crankshaft slowly 1/4 turn anti-cockwise. Turn crankshaft clockwise until timing marks alligned. Slacken tensioner pully bolt. Fit tool to tensioner pulley. Tool No 09244 28100. Apply clockwise torque of 2,6-2,8 Nm to tensioner pulley. Tighten bolt to 43-45Nm. Insert special tool in timing belt rear casing. Tool no 09244-28000. Screw in tool until pin can be removed from automatic tensioner unit. Remove special tool. Tool nr 09244-28000. turn crankshaft two turns clockwise. Wait 15 minutes. Ensure timing marks aligned. Check extended length of pushrod is 3,8-4,5mm. Install components in reverse order of removal. Tighten crankshaft pulley bolts, Tighten torque 20-30Nm

What are the marks for the camshaft on a 2002 VW


There is a cutout on the inner part of the camwheel. It has a demarkation shaped like the tip of an arrow. This should line up to the 3:00 point on the edge of the head. you can tell for sure because at this position you should easily be able to move the camshaft sprocket about 3/4 inch in both directions easily from the pinpoint.

Timing chain


Each gear has an arrow and a dot. The chain should have two differently colored links. Position the crankshaft sprocket so the arrow is pointed up with the dot to your right. Position the camshaft sprocket with the arrow pointed straight down at the crankshaft sprocket and it's dot should also be to the right. The colored links on the chain should be lined up with the dots.
