broken timing belt pulley, and oil pump pulley

[spoolint78]

Well juts the other day i noticed that my rpm gauge would bounce around, and if i got on the gas the car would studder sometimes.

Well when i was driving today, the car stalled on the highway.
I put it in gear to jump start it, no luck.

Towed it home.

Took off the timing cover and the belt is destroyed.

The oil pump driveshaft pulley was busted all the way around.


I did crank the motor for a bit, and when it stalled on the highway, i put it in gear and tried to jump it for 5 seconds roughly at 100km.

I'm wondering if i could have screwed up an engine bearing again, which would suck.

Also, i think with all the shims i had in my pump the driveshaft pulley for the oil was under a lot of stress.

Any suggestions?

i want don't want to run into this problem again
Do you think i could have done damage inside the motor?

thanks

pics will come

Centre ripped out of the Oil pump pully?

Most times I've seen this it's been either or both a) Over tensioned belt b)damaged pully from using something to wedge it while doing up it's bolt.

Unless you have HUGE cams the motor "should" be fine, as long as you weren't trying to roll start it in 2nd at 100 kmh and didn't try for 5Km's the bearings again "should" be fine, no fire no load.

I run 100 psi here and haven't broken one so I don't think it's the pump shims.

Sorry, the oil pump pulley, it broke, and came off of the driveshaft.

The 5 stars attaching it to the out part broke off.

Ya, when i the car was cruising, i dropped it into 3 gear or 4th can't recall for about 5 seconds.

I hope it didn't do any damage

how old was the belt, was it oem, when was the last time you saw it?

Spool: Yep that's the failure I'm talking about.....

If you buy a 2nd hand one spend some time deburring and smoothing the arms as even a small nick will cause it to fail.

Also DON'T go nuts and overtighten the Cam belt
(buy a new tensioner spring and let it do it's job and only tighten the tensioner to 36ft/lbs)

the belt has 2000 km on it.
this is the second time i changed it.
the one before had about 5000 km on it.



IJ, when i tighten it, i just put tension on the tensioner, and tightened the bolt to 36ftlbs.
The belt seemed really really tight.

How else am i suppose to do it?

i think it was all the tension on the pulleys from the belt

 

[spoolint78]

i guess this would explain the miss i had once in a while, and why the car would shudder sometimes.


Now, i want to know if it were possible, or if it is a good idea to weld like a round piece of aluminum on the front of the oil pump pulley, and have the hole in the middle to allow the bolt to pass through. I would then throw on about 5 spot welds to keep it attached to the oil pump pulley.

Is it worth it?
IJ what do you think?

I think you're over thinking it

New pully correctly installed is pretty bulletproof.

Can't weld aluminium to steel/iron

You DON'T touch the tensioner that what the Spring does.....

Follow these instructions to the letter.

someone had an issue with the gear coming apat at high RPM on their motor on SF IIRC...

think they had a billet piece made
