Supra Crank Pully 15+ Years Checkover!!!

I thought id create a thread after the Trouble that L33 had with his car, that may have turned out to be a OLD CRANK PULLY!! That Killed the Engine!!!

Guys please check your Pullys, and make sure there upto scratch. If you think in anyway there not, then replace accordingly to your power requirments. Speaking with JamieP this is a must part to be replacing on an Old Car.

who knows a few quid might just save you a dead engine???

Like a cam belt they are a servicing item and have a life span.

Yes but how often do members check these servicable items?? They only tend to look or check when a problem arises!!

600bhp supra with a 15 year old crank pulley is asking for trouble george, you may get away with it but looking at L33 car its not worth the risk.

I know mate, a boost controller or UK brakes are much more important than something you cant see

Correct dude.

One will be ordered soon as im home.

I have seen crank pulleys that look brand new fall apart and pulleys that look knackered can last years longer, it is very hard to check one properly. As JP says there is more to a big build than the shiny interesting parts.

If enough members are really that worried AFR will supply pulleys cheaper than any other source but I will need to order a few, fitting is also possible.

how much you reckon bud???

Id be interested in getting one soon, as im adding more parts soon for mapping, and i want to know that she'l last until suprapod is over. Then i can break her

I can pretty much gurauntee we can beat any price on stock Toyota parts but there is sometimes a wait for the parts. If there is enough interest I will get a price, would it not be worth seeing if a group buy could be done on a decent front pulley like a fluidamper or something?????

i put a paint line on mine about 2 years ago and nothings moved. the second its not 100% straight its comeing off, i check it every saturday along with all my fluids and tyre pressures before taking the car home for the weekend.

I nearly lost mine on the my first n/a, i know the now banned Moeblunt lost his at speed a few months back.

Big lump of metal bouncing around your engine bay is no fun

Assuming it was on the car from new, (most likely going by its condition). Mine failed at 130000miles/15 years.

I got lucky, I was driving around for a week with strange noises not knowing what it was. As i needed the car i drove it until the weekend, and then when taking it apart the outer ring just came off in my hand.

I can see how they can cause damage. They weigh quite abit, then times that by a few 1000rpm. Disaster.

Seeing all these threads about the crank dampener, i guess i may as well change minel, as i need to fit the belt and cam gears anyway.

Time for an ATI i think...

I use a Titan one, they come highly recommended.

Titan pulleys are just rebadged ati units so basicly you pay for the titan badge

Id use a fluidampr myself. Such an under rated product.

Ati's are still elastomer based and will still deteriorate over time.

I cant see that the power level of the car makes any odds,I had one fall off around 10 years old at idle at a set of traffic lights -luckily no damage

Its just a weak spot and part of having an old car

Ive had nearly 50 year old Jags and the dampers never failed but the supra is prone to it ,you either change it or "do you feel lucky" in a Clint Eastwood style

How much do they cost mate?

any pics of what should be checking here play or poisition in the pulley

only replaced mine 2 years ago! makes a change I done something right as the missis would say!!

What is the best way to check the condition of these guys?

Put a line through it, top to bottom over the central part - if it ever moves/slips so the line is not straight - replace it asap.

Or replace it as you do the timing belt, as some garages use heat and put the old one back on, and then you have a ticking timebomb.

The Tip-Ex test is how I spotted mine
