Chris Coxall Posted December 5, 2011 Share Posted December 5, 2011 Your advice please I'm just about to change the cambelt on my 1.6 K series. The engine will still be in place in the car. What is the best way of locking the engine to enable undoing/doing back up of the bottom pulley bolt. The cams will obviously have the locking tool but how do you lock the fly wheel. Thanking you in advance. Link to comment Share on other sites More sharing options...
oilyhands Posted December 5, 2011 Share Posted December 5, 2011 This has worked on over 100 Caterhams without fail. Above and below the starter there are gaps which allow access to the flywheel / ringgear. A stout screwdriver wedged into the ring gear will lock the flywheel, do not be tempted to try locking by putting the vehicle in gear and standing on the brakes, there is too much wind up in the transmission.

Shad Posted December 5, 2011 Share Posted December 5, 2011 Is there any way to do this once the engine is out of the car? Perhaps if the engine is on a stand? Link to comment Share on other sites More sharing options...
ECR Posted December 5, 2011 Share Posted December 5, 2011 Make yourself a flywheel locking plate (or buy one). It's basicaly a finger that's bolted through one of the bellhousing bolt up holes and latches into the flywheel ring gear to stop it turning. Very easy Link to comment Share on other sites More sharing options...
Tony Whitley Posted December 5, 2011 Share Posted December 5, 2011 The bottom pulley bolt is *mad*ing tight, I think you'd struggle if the engine's out. Link to comment Share on other sites More sharing options...
Wrightpayne Posted December 5, 2011 Share Posted December 5, 2011 I wouldn't put the cam locking tool in place until the pulley bolt is loosened. Ian Link to comment Share on other sites More sharing options...
Englishmaninwales Posted December 5, 2011 Share Posted December 5, 2011 Quoting ECR: Make yourself a flywheel locking plate (or buy one). It's basicaly a finger that's bolted through one of the bellhousing bolt up holes and latches into the flywheel ring gear to stop it turning. Very easy See here This is the correct tool if the engine is out of the car for the front pulley and flywheel bolts Link to comment Share on other sites More sharing options...
Sheds Moderator Posted December 5, 2011 Share Posted December 5, 2011 I did mine without a flywheel locking tool but you have to be careful. The right tool would be a definite bonus. As others have said you must loosen the crank pulley before locking the cams. This isn't something you can afford to bodge up. Link to comment Share on other sites More sharing options...
stevethemook Posted December 6, 2011 Share Posted December 6, 2011 The bottom pulley bolt is a *mad*ing tight, I think you'd struggle if the engine's out. It is..Tried locking the flywheel with a screwdriver..still could not remove it.. So put a socket and wrench on the pulley bolt,placed a piece of wood on the chassis,placed the wrench on the wood ,disconnected the spark leads and turned the engine over.. TAKE CARE IF YOU DO IT THIS WAY AND MAKE SURE THE WOOD IS IN THE CORRECT POSITION...It was the only way I could do it. Everything else was easy Steve Link to comment Share on other sites More sharing options...
Tony Whitley Posted December 6, 2011 Share Posted December 6, 2011 My method is slightly less agricultural! I jack the car up, fit socket with breaker bar so the end is on the floor, lower the car. Link to comment Share on other sites More sharing options...
Mankee Posted December 6, 2011 Share Posted December 6, 2011 I used the DVA method of jamming a big screwdriver/chisel/pry bar in the flywheel area to hold everything still. With the engine out of the car and no flywheel locking tool to hand, I put a couple of bolts that hold clutch cover on, wedged a bar between the two and the floor and a breaker bar to undo the crank pulley bolt.

irrotational Posted December 6, 2011 Share Posted December 6, 2011 Stupid question - how do you get the pulley that tight again, after you have undone it!? Link to comment Share on other sites More sharing options...
Mankee Posted December 6, 2011 Share Posted December 6, 2011 As the Haynes manuals like to say, refitment is the reversal of removal, so jam the flywheel still with your favourite pointy instrument and torque up the pulley bolt. The assistance of a volunteer is helpful. Link to comment Share on other sites More sharing options...
Bricol Posted December 6, 2011 Share Posted December 6, 2011 I did mine by sticking it in gear, sticking the g/f in the drivers seat with instructions to press the brake pedal and simply undid it with a long breaker bar. Done up the same way too, other than subsituting a rather large torque wrench for the breaker bar. Obviously the engine was in the car, and the car was on the ground 😬 Bri Link to comment Share on other sites More sharing options...
