Han anyone help. I ordered a new timing belt and idler for my HZJ80R which has a HZ1 engine. The idler delivered is as per the Parts catalogue but appears to be different to what is fitted. Can anyone offer any suggestion to what is on my engine. Pics attached - hopefully....!

The idler & tensioner in your photo do look very much like the ones that I've just replaced on my KDJ 3.0D4D Colorado/Prado! Have you had a good look through ToyoDiy?

That is does. Interesting that this is on my HZ1. Have looked through Japan-parts.eu for IPC. ToyoDiY does not have it anymore.

It looks like you need a hydraulic tensioner rather than the spring one.

Allied Bearings list 4 versions for the 1HZ, depending on if it needs the water pump, hydraulic tensioner etc. I used them for my timing belt kit for the 4Runner; all NSK or GMB parts and a Gates belt for a very good price.

Your tensioner looks identical to the one on my '97 build 1HD-FT.
TOYO DIY lists some part numbers but I think some of them are out of date. I've changed my belt today with an OE belt 13568-YZZ17 from a Toyota dealer but TOYODIY lists the part number as 13568-19175. I last changed the belt some 50k miles ago in 2005 and that belt has the latter part number but must've been superseded I guess.

Folks, just to close the loop. It looks like I have a '97 HZ1 engine in my '93 Model. The '97 HZ1 has a Hydraulic tensioner. Judging by the missing cross member below the grill the Engine mush have been swapped at some stage. Back to the shop tomorrow.
