How do you remove the timing belt sprocket from front camshaft, 90 Dodge Spirit?
Trying to replace a leaking oil seal at the front of the camshaft.
I've got the timing belt off, and the pulley, and have removed the bolt that secures the sprocket to the front of the camshaft. The service manual shows a flat puller being used, the kind where you secure it to the sprocket using the threaded bolt holes on the sprocket and turn a bolt throught the middle that pushes the flat plate (and anything it is bolted to) away from what the center bolt is pushing against. The sprocket they show has 4 holes, and the photo shows a puller attached to 2 holes on opposite sides, so the pulling force is even (straight off of the shaft). The sprocket I am trying to remove has 5 holes, so none line up directly across from each other. I've tried a harmonic balancer puller, which has two holes directly across from each other and 2 more at about 45 degrees from one of the other holes, - 2 holes line up, but since they are not directly across from each other, the pulling force is not straight off of the shaft, and all I did was bend the bolts holding the puller on. Any suggestions? |
Ok, sounds like the motors still in the car, beleave me it's a cake job
when its out. Anyway it sounds like you do have a striaght shot at the gear. The gear is pressed on pretty well, the bolt really helps on the installing process. The puller is everything, get a good one. Heat will be your friend on this job. Get yourself a Mapp Gas Tourch at Home Depot ~ $15.00. Heat that guy up, Install the puller and go nuts... Good luck. |

I had the same problem with my 89 shelby daytona. I had to make a puller.
Take your crank pully to a metal or machine shop and have them drill holes that match the crank pully holes in a 1/2 thick piece of metal, and for the bolt in the center have them drill a half inch hole and tap it for a course thread bolt and theres you pulley. shouldnt cost very much at all "Chuck" > wrote in message om... > Trying to replace a leaking oil seal at the front of the camshaft. > I've got the timing belt off, and the pulley, and have removed the > bolt that secures the sprocket to the front of the camshaft.
