I have a 1993 2.0Ltr Townace Royal Lounge 2C-T engine. Over the past couple of days my engine have developed a intermitent metallic noise when idling or driving at low speed. It seems to be coming from the pulley which is just above the sump. I sprayed some WD40 onto the pully bearing which stops the noise for a while. Can anyone say whether i should be worried about this and get it changed or is it something more serious!¬!!!!

Thanks

Several owners have had that pulley come loose and make that sort of noise. See Ace Answers > Engine mechanical > Pulleys. If that is the problem then fix it before it comes off and leaves you stranded with serious damage inside the engine.

Uh, I don't think this one is a seperating crank pulley, more likely that the a/c belt idler pulley bearing is dodgy. The pulley is easily removable, and IIRC the bearing can be pressed out from the centre of it for replacment.

Thanks David, I assume i can get the bearing my local toyota dealer. Secondly after i have replaced the bearing and refitted the belts, do you have any guide to how tight they should be. The engine manual shows using some type of tension gauge.

Thanks again for your assistance

hi everyone the bottom pulley on my townie has sheared its bolt and fell off, my garage has tried to get it out by chisseling it round but no joy they say the only way would be to remove engine and get a specialist to drill out and re tap is this my only option any ideas out there before i sell it as a spares wagon.

Check the archives, someone (Stephen Judge?) was able to drill the bolt out in-situ.

This should really be in a seperate thread, you know...

Rich, you can buy the complete pulley from the dealers, but the bearing on it's own would best come fronm your local bearing distributor.
How tight? Tight enough that they don't slip, but not much tighter ;-)

Rich. Are you using the engine manual Code RMO25E ?
If so, the belt tensions are given on page EM-37 and, if David's diagnosis is right, and it is the A/C belt, the deflection should be approx 3-4 mm for a used belt, with an applied load of 10KG. If you have a spring balance it helps but a bit of guess work, and applying a fairly stiff push to the top of the belt, should bring it to the right tension. (Try pushing on the bathroom scales to simulate a 10kg load)

sorry for jumping on your thread i thought i had put it on as my own.

Just to say thanks again for all your help

Cheers

Rich, let us know what you find.

At least with the a/c belt you can adjust the tension without having to take out the floor.
