l.chris97 Posted November 27, 2011 Share Posted November 27, 2011 Just completed my cambelt change today,and as per norm the crank pully bolt was as tight as f*ck,pulled the bottom pulley and timing sprocket ( replaced crank oil seal ) While building up after the replacement i inspected the crank pulley and found a hairline crack from the edge of the woodruff key cut out and its spanning out throught the metal body of the pulley has any1 had this problem before or have i got another problem that has caused the pulley to split, really dont want to buy a new pulley to have it split also... Any help or ideas guys???? Quote Link to comment Share on other sites More sharing options...
Rob Posted November 27, 2011 Share Posted November 27, 2011 If its cracked you'll need a new one of course. How old is the car? Old enough for a previous owner to have had a go at hammering away at the pulley, trying to get it off/on when he didn't know how? Quote Link to comment Share on other sites More sharing options...
Nic Posted November 27, 2011 Share Posted November 27, 2011 has any1 had this problem before or have i got another problem that has caused the pulley to split, really dont want to buy a new pulley to have it split also... Agree with Rob someone has probably attacked it with a hammer, they don't usually crack from just wear and tear, although they can separate over time. A new OEM Toyota pulley should last many many years, part number below. 13407-46020 Toyota Harmonic Balancer Quote Link to comment Share on other sites More sharing options...
Dnk Posted November 27, 2011 Share Posted November 27, 2011 Wouldn't it be fairly obvious if it had been abused ? Also the crankshaft nut that holds the pulley in place is meant to be tight, 330 Nm or 243 ft-lbs to be exact Quote Link to comment Share on other sites More sharing options...
l.chris97 Posted November 27, 2011 Author Share Posted November 27, 2011 The cars a 94 rz...the pully doesnt look as if had been hammered but it def had been of before as the bottom timing cover was missing when i got the car... the other thing i noticed was the timing wheel was really tight to get back on the crank and i had to use a socket and hammer it tap it back on and used the bottom bolt to pully the crank pulley on....... I starting to think there is something up with the end of the crankshaft guys esp were the crack in the pully is Quote Link to comment Share on other sites More sharing options...
Scott Posted November 27, 2011 Share Posted November 27, 2011 The timing wheel is meant to be tight too IIRC. Not OVERLY tight but it should be fairly hard to press on. Could you not have used the timing bolt with a socket though rather than hammering it on? It's rather important to put it on square. Quote Link to comment Share on other sites More sharing options...
l.chris97 Posted November 27, 2011 Author Share Posted November 27, 2011 I used the tool to start the wheel on the shaft scott then just finished it by tappin it on with a hammer no hard or heavy shots were needed its was just to put it home on the shaft...only reason was the tool i made up wouldnt push it fully home as it hadn't got the reach needed.

Scott Posted November 27, 2011 Share Posted November 27, 2011 Probably fine then. That's perfectly normal for it to be a slight interference fit though. Quote Link to comment Share on other sites More sharing options...
l.chris97 Posted November 27, 2011 Author Share Posted November 27, 2011 Cheers let hope its just a dodgy aged pully thats caused it to crack...its been cracked for a while to as the crack itself is full or oily grit...so prob just luck i've gotten it before it decided to claim my fan and rad and god knows what else Quote Link to comment Share on other sites More sharing options...
