(Bottom altenator mounting hole) I hate to say it, but this is more likely to have snapped than the alternator itself. Not that that's the problem, but it's worth checking before deciding on future direction. Yes the lower mounting tab has sheared off from the block.

markssupra Posted May 9, 2013 Share Posted May 9, 2013 Sorry to hear this mate, I would be concerned as to why this one broke up into pieces. I have been making cutting tools for 29 years with sizes similar to the crank pulleys diameter and bore sizes, balanced to run at speeds of upto 15000 rpm, never had one let go like that. I can only think that the material the pulleys are made from are sintered metal and had a flaw. Normal steel would not explode like that. Let me know if you need any help bud. If you have a piece of it left, let me have a look at it when I next see you. Link to comment Share on other sites More sharing options...
Monkpower Posted May 9, 2013 Author Share Posted May 9, 2013 I don't think its worth putting another NA lump into it to be honest. A TT lump is out of my price bracket and you can't keep it stock which means the W58 wouldn't last that long. Link to comment Share on other sites More sharing options...

Digsy Posted May 9, 2013 Share Posted May 9, 2013 Had the new part been off and on again in between fitting and failure, maybe to replace the timing belt? If so did anyone use a blowtorch on the crank pulley bolt? Link to comment Share on other sites More sharing options...

Chris Wilson Posted May 9, 2013 Share Posted May 9, 2013 (edited) I would suggest the nose of the crank, or the Woodruff key way is damaged and the dampers are coming loose and failing. Have fitted 3 dampers this year on engines that REALLY should have had a new crank, but the cost was prohibitive, so Loctite Bearing Fit, a new Woodruff key, and a few prayers from the owner were the cheap way forward. Next time the damper needs to come off though, it will prove challenging for someone!

Next time the damper needs to come off will prove challenging for someone though We had a chat in the tea room about the same possible thing with crank damage and the woodruff key worn which would cause it. We have contacted Mr.monk to see what he wants to do but we only really want to fit a freshened up second hand engine for our peace of mind.

Next time the damper needs to come off though, it will prove challenging for someone! Thing is, the key should only be there for alignment. The loads should be reacted through the bolt and the friction between the pulley and the crank. Once the bolt is tight it shouldn't matter if the there was no key in there at all. If the bolt has relaxed it might not be applying the proper clamp load, which would indicate that the bolt should be replaced each time the pulley is removed (which isn't bad practise for yield-tightened fasteners, anyway, although you can usually get away with a couple of re-uses). If the nose is damaged, on the other hand, allowing the pulley to be fitted with some eccentricity, that may well make it come loose. I would have thougth you would have felt the vibration, though.

Dnk Posted May 9, 2013 Share Posted May 9, 2013 Forgive me if i missed it but did the pulley seperate like they do when they get old or did the whole thing come off the crank ? Link to comment Share on other sites More sharing options...

Monkpower Posted May 9, 2013 Author Share Posted May 9, 2013 It separated, the larger back part broke into pieces. Link to comment Share on other sites More sharing options...
Dnk Posted May 9, 2013 Share Posted May 9, 2013 (edited) Faulty crank pulley perhaps, was it a genuine Toyota one or a copy. I can't see how a good one would fall apart unless it wasn't true on the crank, in which i mean the centre bore is out of true with the rest of the pulley Toyota part should have 1 year warranty on it i think Edited May 9, 2013 by Dnk (see edit history) Link to comment Share on other sites More sharing options...
Monkpower Posted May 9, 2013 Author Share Posted May 9, 2013 Genuine Toyota part purchased and fitted at Whifbitz. Whatever the problem was it looks like i'll be letting the car go. Link to comment Share on other sites More sharing options...
