Guest TurboSedan Posted March 21, 2005 Report Share Posted March 21, 2005 well the upper one that bolts to the camshaft was easy enough to remove, however i cannot get the lower sprocket off (the one on the crankshaft). i tried using 2-jaw & a 3-jaw puller and no luck. what's the right way to get this thing off? heck i might just take it in....i'm sick of working on car(s) i want to drive them@!!@!!@!#%$!@# Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted March 22, 2005 Report Share Posted March 22, 2005 fuck it....i think i'm just going to reuse the crankshaft timing chain sprocket... Quote Link to comment Share on other sites More sharing options...
99RegalGS Posted March 22, 2005 Report Share Posted March 22, 2005 When I did the timing chain on my Regal a year ago, the kit didn't even come with the crank sproket. So I think you're plenty safe. Quote Link to comment Share on other sites More sharing options...
Justin Posted March 22, 2005 Report Share Posted March 22, 2005 REMOVE OR DISCONNECT Timing cover Place # 1 piston at top dead center with the marks on the camshaft and crankshaft sprockets aligned (#4 firing position). Camshaft sprocket and chain NOTE If the sprocket does not come off easily, a light blow on the lower edge of the sprocket (with a plastic mallet) should dislodge the sprocket. Crankshaft sprocket It should just be held on by the keyway on the crank, right? I sure wouldn't leave the factory one on there, I was taught to always replace the timing chain, and all the pumps (water/oil/fuel on older cars) whenever you build a new engine.

Robby1870 Posted March 22, 2005 Report Share Posted March 22, 2005 Yeah, its just keyed on there, should pop right off. Maybe with a little convincing from a hammer or something. Quote Link to comment Share on other sites More sharing options...
Turbocharged400sbc Posted March 22, 2005 Report Share Posted March 22, 2005 use a two or three jawed puller and it should come off no problem however if the gear isnt worn too much you can reuse it look for deep wear lines if you can catch your fingernail in them you might want to replace it... otherwise just put the chain and cam gear in there! I have talked to several of my fellow mechanics and we are pretty darn sure that they are non-interference engine, none of us have ever seen bent valves from a t chain failure (and for the record 3 of us have seen the cam gear rounded completely off and 4 have seen a single link break (one of em me...) Git 'er dun! James so does this mean that i won the bet in the other thread on this topic-the link breaking?!? LOL Quote Link to comment Share on other sites More sharing options...
Brian P Posted March 22, 2005 Report Share Posted March 22, 2005 Are you doing this with the engine in the car? If it's not chewed up, and the engine isn't staying in there long term, I guess you could take a chance. If you damage the crank or old sprocket trying to remove it and it STILL doesnt come out, there's no turning back. Quote Link to comment Share on other sites More sharing options...
SleeperRed90TGp Posted March 22, 2005 Report Share Posted March 22, 2005 The crank gear is a bitch to get off. It's pressed on as hard or harder than the pulley. Here's a tool that will seperate it from the crank. Autozone loans this tool. Once you get it seperated you can pound or pull it off. It's the initial 1/8" thats the tightest. Bearing seperator. http://buy1.snapon.com/catalog/OBJECTS/21100/21009.JPG I used a sharp chisel last time I did it to get it loose from the crank and then pounded it off with a brass drift. Check the crank for any bumps and file them off. Good luck. Jud Quote Link to comment Share on other sites More sharing options...
TGPilot Posted March 24, 2005 Report Share Posted March 24, 2005 Heat and a 3 jaw puller. Heat the piss out of the gear without getting direct heat on the crank-end shaft. Put tension on it and smack it with a peen hammer...should break loose... 8) Quote Link to comment Share on other sites More sharing options...
