Alignment of pullies

[RB zook]

ok so ive got my pwr steer pump and making thr brackets

thou i know it is critical to get then 2 pullies perfectly inline other wise it will be killing belts in no tiome

is there a certain way to get them lined up or i just do it to wat i think is good and carry spare belts?

[bazooked]

use a straight edge on 1 pully and check the diff against the other 1

Yeah thats what i did when I fabbed up a bracket for a Commodore pump on my 40 series

if its a v belt, miss alignment by even an obvious amount is ok. a serpentine well get it a bit better. i ran the toyota powersteer on my chev350 in the bundera and it was out by 7mm and it was fine. it couldn't be right as the pump bottomed out on the block and simply stuck out too far

I'm running a different alternator on my engine and the pulley is out by a bit (v belt). I had a lot of belt squealing due to the misalignment, but some GUD Drilube has fixed that.

The belt doesn't seem to be suffering at all and has been like it for about two months now.

should be rite

just concerend about belt last abilit guess just keep a spare one in the car

try to get it as good as possible. Missalignment will place stress on pump seals and bearings as well as the belt! If you can't fit a straight edge in the engine bay try using a piece of string. Hold it tight on one side of one of the pullies and slowly move it till it lines up with the other pulley. Seeing where it first touches the other pulley (near or far side) will indicate the alignment. This is the method we use to align fans, compressors etc when there is insufficient room to fit in a standard straight edge such as a spirit level or straight piece of steel.

A little bit of misalignment is OK until your running along at 100ks for a couple of hours and the hot belt flys off taking a hose with it

or your in the middle of fucking no-where and you forgot to bring a socket set along with your spare belt so you got no hope in hell fitting the new one!

just use your shoe laces when the belt brakes worked for me for a few ks any way

We had a hilux at work that had a misaligned alternater mounting. What ended up happening was the load placed on the harmonic balancer ripped it off its vulcanised rubber and forced it back into the timing case. Eventually it tore through the case (which is just plastic) and jammed the timing belt, which made is shear all its teeth off, stopping the camshaft from rotating. Piston then came up into No.3's intake valve and forced the whole valve into the cam and snapped it at its journal. New long block from toyota was $7500.

Moral of the story is, yes, alignment of your pullies is farking critical in my book.

Gribble, what sort of misalignment are you talking about here? A couple of millimetres, or a lot more? Was the belt overtensioned too perhaps?

[RB zook]

its all mounted and i moved when i welded the bracket

its 1 mm out over the distance of the pully

thou hopefully when i get the belt and tention it it should pull into line

i thiing it will be rite

[bj42turbo]

1mm is that all it will be fine

[RB zook]

haha i got sent a pic of a belt thats 20 mm out and

he has only ever done 1 belt due to it being old as

I dont know, this was about 2 years ago and my memory sucks ass. But it would have been at least 10mm. It would have been hard to tell if it was overtigtened because the balancer had shifted.

I dont think 1mm is anything to worry about. Most factory engines arent even that close.
