Mark, If you haven't already registered on the mbclub UK forum, suggest you do so. When you have, log on, go to the "How to" section and there is a step by step guide, with photos, on rebuilding the M103 cylinder head. Good luck with the new car. |

One tip i would give you is get a bungee cord with hooks on to hold the pulley up to the bonnet hook, cut the heads off the old head bolts and deburr and cut slots into the tops. One you have cleaned the gasket surfaces and fitted the dowels drop the gasket onto them and approach the car with the timing chain void facing the car, rest the head on a piece of sponge, block of wood etc on the slam panel and unhook the bungee from the bonnet, keeping enough tension on the pulley to stop it dropping and pass it through the void and rehook it. Now you can hold the head and turn it through 180 degrees and allign it square on the dowels without the gasket moving or the head slipping and damaging anything. Its a heavy lump to be lining up at arms length gently. You can remove the home made dowels using a flathead screwdriver. You only need to make 2 really but I tend to do 4. The bungee i found was easier than string, cable ties etc. Edited by Richy190E, Fri Nov 6, 2009 11:20 pm.

it pushes out mate, you may need to tap it a little. whatever you do dont push the piston back, it must come out in the direction of the chain. I think last time I put a 1/4" extension bar down it and tapped it on the bench. Or I may have gripped the body in the vice, fitted the spring and scrrewed the cap on, either way should work buddy. |

you will need the body of the tensioner off the engine, its one way only. once the chain is in position you fit the piston spring and cap and it auto tensions on a ratchet mechanism of grooves and circlip. |

tis ok. i done it... i found out that there was a threaded washer within the block..... undid it, fitted te sprocket and put it back in.... one question.... the threaded washer that is removed after the spring within the tensioner...... when it is put back in, how tight does it have to go.... seams to be going in further than it came out..... i dont want to do any damage, or over tighten the chain... advice asap would be great... |
