The top idler pulley on my 1992 LS400, has suddenly become a bit rattly and so is due for imminent replacement. Can anyone recommend a good source and replacement, please? I am in the UK!

Secondly, is there need for replacement, in that a shorter belt modification could be advised?

Thanks

Hi,

I would imagine this is a dealer only part and I cannot find the part number on the database, mine squeels for around a minute in very cold weather then shuts up,been like this for 3 years and never got worse.

Unless the bearing has play in it you could try a squirt of wd40.

If I remember correctly there is a fair amount of dismantling to do to remove the idler in order to replace it.

Yes, there looks like some small access issues here, but I'll have a better look and trial tomorrow.

I have seen after market replacements on US sites. Some here will know that I come from a Saab Background, and have serviced idler pulleys in the past on my vehicles, hence my raising the shorter belt by-psss option. I'd be more inclined to used silicon grease than WD40, TBH.

I can see that the bearings are not at their best at the moment. Is it a sealed unit, or serviceable, I wonder?

Thanks for that - seems about the right price. I was going to look through and see if Saab did an equivalent - couldn't think of something off the top of my head. There's an independent Lexus specailist in the area, so I'll go and introduce myself :)

Aftermarket replacements (e.g. ADL Blueprint) are available for the IS200's idler pulley, they may well do the same for LS400, I don't know, you coudl try asking at your local motor factors.

Thanks, Stevie - there's a goldmine of a little motor factors near me, they always have parts or can source for me - better than the major large chains!

Popped into the local factors. We looked up on their part books, trawled their computer, and phoned a few people - seems this is a Lexus (Toyota) part only. will look into next week - I have to pick some ordered goods from the factors up on monday, anyway, and dealership is not very far away - roadworks and bridge closures permitting.
