Uneven Idler Location Fix

[ST240]

Theres the spacer. I'd heard of people talking about it but never saw a pic. Now we have one.

A guy will need a custom stud OR you can get away with a stocker if you put a little shim in the hole for it to bottom out on higher thus having less thread engagement. otherwise you won't even stand a chance at getting the nut on the stud with the pulley there.

Hope this helps someone!

Where did you get it from?

Does it make it PERFECTLY level? I've had one of mine have only a few degrees of tilt and it threw the belt off...

without a mill to put the block in, would be hard to get it exact

[ST240]

Threw the belt off when you had the engine running?! Or just spinning by hand?

I made that with my machinist like i said. But no, I'm guessing that its not perfectly level.

If i spin it over and over again will it come off? Or do i have to find out the hard way .

does this mean that you cant just put the tensioners on and away you go when doing the rb25-30 conversion running the twin tensioner setup with one in the new position?

is it the new spot that is the problem? or have i got it wrong?

never heard about this when getting mine ready. thought i was almost ready to go in a couple of weeks. maybe not now

I think this is a safer setup, you just turn 10mm off the back of the tensioner post. It fits inside the cover and everything else fits as normal.

Am i missing something, isnt it just easier to use the correct block?

[proengines]

Yep, obviously easier to use a block with the machined pad for the tensioner but a lot of people get underway on an engine without realising it. There's really no problem using the earlier blocks as long as it has the oil feed for the turbo drilled through and a drain. I got these plates laser cut because I had 3 people in a couple of months with the same problem and it was a pain milling them up.

M10x1.5 where they screw into the block.

Would only do it when running.

If it's off majorly, it'll do it by hand also.

pretty trick piece of kit that plate is...glad i got a proper 's2' block for my conversion that had the tensioner filled in properly.
