Changing Crankshaft Pulley

[Guest naylor]

Hi Guys

 

Could anyonr give me some pointers for changing the pulley on my 2002 hdi 110, I know its not a mojor job as ive seen one done in mins. any advise would be greatly appreciated.

Haven't done an HDI but plenty of XUD's. You'll need to remove the undertray and the inner wheel liner. Remove the front o/s wheel. Put the handbrake on tight and in gear and undo the crankshaft bolt. It will undo easier if it's done hot. It also has locktite on it so it will be difficult. Make a note of the run of the auxilliary belt before you remove it.

Thanks a lot for the info m8 what gear should the car be in and is it a hard job to tension the auxillary belt.

 

cheers

Put it in top gear. There's an auto tensioner on the auxilliary belt.

nope it don't work like that just putting in gear doesn't work the flywheel has to be locked in position ( TDC )

just above the starter motor there is a hole insert a timming pin or a 8mm drill bit into it then turn engine over by hand untill you feel the bit lock into flywheel. then remove the cener bolt from the pulley and prise the pulley away from the end fo the crank then put the new pully in its place and put fan belt on and remove the drill bit and your done. check with the dealers as im sure your supposed to replace the bolt aswell if not put loctite on the old one when refiting it

So there you are Naylor, you've got conflicting advice for your job. All the best with it.

 

“nope it don't work like that just putting in gear doesn't work the flywheel has to be locked in position ( TDC )”

 

“just above the starter motor there is a hole insert a timming pin or a 8mm drill bit into it then turn engine over by hand untill you feel the bit lock into flywheel. then remove the cener bolt from the pulley”

 

 

Here’s what Mr. Haynes says,

 

To prevent the crankshaft turning whilst the pulley retaining bolt is being slackened, select top gear and have an assistant apply the brakes firmly. Alternatively the flywheel ring gear can be locked using a suitable tool. Do not attempt to lock the pulley by inserting a bolt/drill through the timing hole. If the timing pin is in position from a previous operation, temporarily remove it prior to slackening the pulley bolt.

I wouldn't say conflicting ways just ways to do it and what your doing like if your changing the timing belt the flywheel has to be locked so it really depends on why you want to undo the main crank bolt,

as for what tool to use the drill bit could be dodgy because it could shatter due to the high torque on the bolt but I use a junior hack saw frame without the blade of course as its very strong and fits perfect and it is like a tool with a handle
