MG MG Y Type - Extracting Flywheel

Having removed the engine & gearbox from my YT, I am now in the process of dismantling. I have undone the Flywheel bolts. Does anyone have any suggestions on how to remove the flywheel once the securing wire & bolts have been removed?

Many thanks

It should not be too difficult. Just a bit of friction where the flywheel overlaps the crank by about 3 mm and the two dowels. If you hold the crank by the front counterweight and hit the flywheel with a rubber mallet it should fall off. Have it close to the ground and don't have your toes underneath!

Two long flat bladed pry bars and gentle pressure at 180 degrees with a third person just there in front to catch it and stop it from flying out and dropping onto the floor.

Hi Bob & Paul

Many Thanks for your suggestions, which proved most helpful. I used the procedures and the flywheel came out quite easily onto a thick rubber mat I had placed on the floor. The engine is now dismantled and will be going for a re-bore in the next day or two, once I complete cleaning up everything.

When I come to re-install the parts, I will need some advice on how to line up the camshaft and the crankshaft sprockets. Both have a 'T' marked on them, but the existing timing chain does not have the white links as described in the Workshop Manual.

Many thanks

Best wishes

You definitely need to follow the Neil Cairn's Engine Rebuild Diary that is on our site. http://www.mgccyregister.co.uk technical info, engine rebuilds. Here is an extract from Day 10 that answers your question.

Two timing chain marks with chain in position.Timing chain mark.Now you can fit the timing chain and its sprockets as long as you have already fitted the keys to their keyways. But first, using a new gasket, fit the front engine plate that the front engine bearer is on. My new camshaft chain did not have two bright links! So I had to use the workshop manual to paint a bit of silver onto the links 1 and 15 (see page A20 and section A28 in the manual for more info.) so I could line up the two ‘T’ stamped on the sprockets correctly. This means the valve timing is correct. Remember to fit the crankshaft woodruff keys to the cam sprocket shaft and the fan pulley first. If you miss out the fan’ key you cannot time the engine! The camshaft sprocket’s nut is locked with a locking ‘tab’ washer that locates in the key-way hidden under the big washer. Now fit the timing chain tensioner remembering to wire-lock its two bolts. Oil the chain liberally.

Hi Anul

Yes it is quite simple - count the links in the new chain then paint the links - I used regular standard white-out or Snopake liquid paper correcting fluid on mine. You only need a small dab on both sides of the chain so it doesnt matter which way round you fit it to see them. Then just follow the manual. Getting the gears on and the chain can be a challenge so you may have to put the cogs and chains on at the same time as the tension wont let you do it any other way.

Also be careful not to knock the woodruff keys out of their grooves when putting the cogs on. It may take several goes to get them on but keep trying and you will get it eventually.

Thanks for your advice which is again most useful. I ill certainly look through Neil's write up and hopefully get it right.
