Mike Walker 0 Posted October 6, 2006 Hi peeps I've had a look in the Haynes manual at whats involved in re-shiming the cam. It seems that i'll need to do the timing belt, remove cam, shim it up correctly, refit, time it up etc. If I do this i'll need to be able to do it in a weekend as I need the car for work. I've never touched anything to do with the timing or cams before so i'm not confident it can be done in the timescales I have and with my mechanical ability without the possibility of fecking it up?

Mike Walker 0 Posted October 6, 2006 Well, the garages are quoting 4.5 hours so I guess I should look at taking 9 hours + Share this post Link to post Share on other sites
boombang 2 Posted October 6, 2006 If its purely that the cam/buckets have worn and its slightly rattly then its considerably easier than starting from scratch (as I am currently doing!). A weekend may be tough though unless you have a good supplier of shims locally. 1. remove rocker cover + spray bar, leaving engine + belts in position. Put engine in right position for each cylinder and measure your clearances. Note the clearance for each lobe. 2. remove aux belt, remove belt covers, undo tensioner, remove pulleys + cambelt. remove dizzy + stat/dissy housing. 3. undo cam cap covers bit by bit and in sequence, remove cam. 4. Remove buckets + shims. Measure shims and note down shim for each bucket/lobe. To get the new shim size required add the shim size to the clearance measured and subtract 0.20 to 0.25 to inlets and 0.30 to 0.35 to exhaust - this gives you the new shim size required. Shim sizes available from Peugeot are here: http://www.stuartmcguire.co.uk/pug/GB/205F/0/09A90A.HTM http://www.stuartmcguire.co.uk/pug/GB/205F/0/09A91A.HTM 5. Once shims you ordered arrive (that the tricky bit if you need to do it over a weekend!) put them in the correct buckets, fit everything back to engine and check clearances. If any out re-measure shims, and re-order/swap as necessary. 6. When happy remove everything and go for a final assembly. I would use new water pump, new tensioner and new cambelt. Remember gaskets and sealant where necessary in re-assembly. Tools you need IIRC are: 4 or 5mm allen key (unsure which) for the bolt that goes into cam cap behind dizzy on dizzy/stat housing 6mm spanner for tensioner 13mm full hex head socket for cam caps 10+11mm sockets for cambelt covers 23mm??? for crank pulley + something to lock inside the flywheel ring gear in gearbox to undo. some sort of measuring calipers (must be accurate!) feeler gauge new cambelt, water pump, tensioner, stat housing gasket, rocker cover gasket (not essential but often worth replacing if old one has gone hard) Its way easier than you think and unless you screw up timing, belt tensioning, use crap tools, can't measure things or can't add up/subtract pretty hard to f*** up.

boombang 2 Posted October 6, 2006 hope this helps, and sure I have forgotten some bits! I was doing this yesterday but got stuck as no shims small enough due to valve seats having been cut back. On a 3mmish shim clearance was... nothing Share this post Link to post Share on other sites
GLPoomobile 958 Posted October 6, 2006 I wouldn't recommend anyone who hasn't done something like this attempt it if they only have a weekend. In principle it is straight forward, but there are too many things that can go wrong and cause delays. For example, when I refurbished my cylinder head, I had a new timing belt to go on. Could I get the f***er on? Could I feck! I ended up having to put the old one back on and even that was rock hard. It was something that shouldn;t necessarily have been difficult but for some reason I had problems and it obviously delayed me by hours. Share this post Link to post Share on other sites
boombang 2 Posted October 6, 2006 Agree with the above. I think the key point I missed making was you will not be able to do it within a weekend unless you have easy access to lots of different sized shims. Share this post Link to post Share on other sites
Mike Walker 0 Posted October 6, 2006 Thanks for the advice Seems like a job that'll take two weekends then, one to get everything off and measured and shims ordered and the next to re-assemble (and then I can't even guarentee that it'll work or the shims I got will be right!) Looks like I might have to bite the bullet and fork out the £250 to get it done by a garage It's been like this since I bought the car which had only just had a head rebuild so I guess that whoever rebuilt it didn't get it right in the first place - tschhh, numpties Share this post Link to post Share on other sites
GLPoomobile 958 Posted October 6, 2006 Does anyone know how much 205 Parts would charge for this? I have emailed them twice and got no reply (I know, I should just call them)? I really need to sort mine out and just can't be bothered. If it's up to about £80 then I can just about swallow that, but for £250 I'll soon motivate myself into doing on my own!!

hengti 2 Posted October 6, 2006 somewhere on here (try searching), PumaRacing has suggested a set of non-std clearances that apparently help greatly in reducing valve train noise. wish i'd had the garage re-shim the cam to Puma's specs when they did the HG on mine Share this post Link to post Share on other sites
welshpug 1,657 Posted October 6, 2006 dont forget a decent set of timing pins/locking tools, makes timing it all up so much simpler. Share this post Link to post Share on other sites
Jer309GTi 3 Posted October 6, 2006 Anyone on this forum work in a machine shop? Maybe we could sort out a group buy on here where they machine up loads of different sized shims on a large scale so everyone could have a wide variety to choose from? Just a thought Share this post Link to post Share on other sites
mossy 0 Posted October 7, 2006 (edited) I did my shims a couple of months ago. Engines done 97k. Easy job I know a very good machine shop (lad next door is the MD) He made me a set up to my own measurments but I don't know if he will do any orders as hes very busy. I could ask when I'm back up north though. I said its easy but have you got the correct tools for the job? You will need a digital set of calipers or good micrometer and also a very large range of feeler blades for getting the cold clearances as exact as poss' Hope it makes sense. Ps you can cheat with the cambelt if its not to old. Set to TDC mark the cambelt and sprocket ( tipex pen ) undo bolt slide pulley and belt off.
