Alternator belt jx engine

[Theclash]

Mates alternater belt snapped on his JX he as a belt in front of it running crank pulley to waterpump pulley so we need to take this belt off to install the alternater (waterpump to alternater) belt , question is where or how is the front belt tensioned

[dave friday]

The water pump pulley is in two halves with tension adjusting shims in the middle,any unused shims are put on the outside of the pulley.
So.. To tighten the belt take a shim out...

[Theclash]

So how do you slacken the belt to remove it while we slip on the alternater belt
Also how do you stop the waterpump pulley spinning while tightening it up

[clift_d]

Take out the three bolts to split the pulley and allow the belt to come off - reverse to refit.

To stop the pulley spinning while you do this you need to improvise something to hold the pulley stationary. Either that, or buy something like this:

Thanks very much great info...not used to working on these dirty dervs

[dave friday]

When I remove the pulley I use two Allen keys, one to stop it moving one to undo it;or pipe grip on two bolts and undo the third!

Thanks davefriday will give it a try next Saturday.....keep your fingers crossed
