collapsed oil pump pulley.(big pic warning)

[NDBoost]

seen thsi happen on a $4k build up with a local supra owner here. Running a GT40 on a fresh rebuild. Got 100 miles from home and his car died, checked the timing belt sure enoguh it came off. The culprit was a shattered oil pump pulley, replaced it and its good as new.

Didn't mellowyellows car do the same also? aight peace :chicken:

Or, try hooking a right angle drill up to the oil pump drive shaft with the key on and spin the drill while someone verifies oil pressure at the gauge?

Not sure this will work, just an idea..

That idea did cross my mind, but it sounded too easy:icon_bigg

Can anyone verify if this will work? I think it should, but i'm usually wrong with these things.


NDBoost: Youve just settled my nerves alot. Thanks.

The drill thing will work fine Bob!

Make sure you use a drill with a clutch though to save shearing the bolt off it's only an 8mm and not hitensile.

Cheers IJ, i'll try it then, and let you all know how it goes.

same thing happen to me today. fuckin pully broke into like 10 pieces.

did you guys check the 8mm bolt?

I had somethin g like that happen and it was the damn bolt stretched that it broke loose. Upon putting a ratchet on it sheared cleanly off.

who did the belt?

i say.... person that did belt used oil pump pulley as leverage or something and hence weakening it then big bang and breaks

never ever have i seen that before

 

[IJ.]

All it would take to weaken the pully is a small nick in any of the spokes..... :nono:

Well, just to add a bit of closure to my story, i've stuck another pulley wheel on, (using the original bolt, which torqued back up just fine) a new belt, and everything is back to normal. (oil pressure is stil good too).

I'm just putting it down to the 100,000+ miles of stress.
