Don Cook Posted May 12, 2014 Share Posted May 12, 2014 as above 2 ltr XE with caterham dry sump set-up. Anybody know how to get the pulley (alternator drive) off? Cheers, Don Link to comment Share on other sites More sharing options...
ECR Posted May 12, 2014 Share Posted May 12, 2014 You need to lock the flywheel to prevent it turning and then it's just a matter of brute force. The crank bolt is mighty tight and I use a breaker bar with an extension tube. You can make a flywheel lock very easily with a piece of scrap steel and a 12mm drill .... I think your engine is out of the car ? Make sure it is well supported before trying to undo the bolt Link to comment Share on other sites More sharing options...
Mavic82 Posted May 12, 2014 Share Posted May 12, 2014 Just to add it depends which bit you want off. The alternator and dry sump pulleys simply unbolt with the 8 or so and 3 cap heads respectfully. The cam belt pulley as Roger suggests needs a flywheel lock and a big bar. Link to comment Share on other sites More sharing options...

I reply to every thread Posted May 12, 2014 Share Posted May 12, 2014 I have a recollection of hanging off a 10' scaffold pole while removing EFA's......... Link to comment Share on other sites More sharing options...
Paul Deslandes Posted May 12, 2014 Share Posted May 12, 2014 tightening it after refitting can be something of a challenge too.... Did you get the manual okay? Link to comment Share on other sites More sharing options...
Grim Reaper Posted May 12, 2014 Share Posted May 12, 2014 Don, I have a 1m breaker bar if you want to borrow it, or a decent pneumatic impact driver (450 ft/lb @90psi) if you have a compressor that is up to it. Link to comment Share on other sites More sharing options...
k.russell Posted May 12, 2014 Share Posted May 12, 2014 If it is to replace cam belt you will need a good quality impact socket. And replace with a new bolt. I have done mine a couple of times with a drill bit through flywheel hole to block, needs to be a very close fit in hole Edited by - k.russell on 12 May 2014 21:45:57 Link to comment Share on other sites More sharing options...

AJC Posted May 13, 2014 Share Posted May 13, 2014 Er ..you shouldn't need to remove the big bolt to just do the cambelt ,only to get the oil pump off.If its on the floor angry grinder the head off and the rest will walk out once the tensions off it.

ECR Posted May 13, 2014 Share Posted May 13, 2014 You don't need to remove the large vee alternator drive pulley to remove the belt but it does need removing to re fit one. Which brings us neatly back to Mavic's earlier post Link to comment Share on other sites More sharing options...
Don Cook Posted May 13, 2014 Author Share Posted May 13, 2014 Hello Gents, Thanks for the help. I don’t need to remove the timing belt pulley just the alternator and dry sump drive pulleys. The bolts that attach the alternator drive pulley to the crank are covered by an aluminium casting so are not accessible. The dry sump pump drive pulley has 3 very small allen bolts on the end. These don’t look big enough to do much. The question is I think, how to remove the aluminium cover to get access to the bolts behind. Thanks, Don.

ECR Posted May 13, 2014 Share Posted May 13, 2014 If this is the standard Caterham setup, then Mavic's instructions will work. The 3 small cap heads will remove the dry sump drive pulley, then remove the (6 ?) M8 bolts/capheads and the pulley will fall on your foot 😬 Edited by - ECR on 13 May 2014 17:34:23 Link to comment Share on other sites More sharing options...
