Re install them , they actually bolt the middle of the timing cover back into the block

 

I'm assuming by 17mm head that means these are a M10? Can anyone confirm the thread size/length of these? I want to order nice socket cap bolts to match the rest of my timing cover hardware.

 

if its like the rest of nissan, its probably a m10x1.25

i ordered the Z1 light weight pulley and it came with the idler delete free.

 

I've been searching for the answer to this question as well. Can't seem to find it, did I fail on reading comprehension with this thread or did no one ever find out?

 

Sorry for not updating, I used Gates K060435 6PK1108 13/16"x44-1/8"OC 20mmx1122mm OC

 

I need to compare those to the ones I'm using

 

I did this the other weekend. Just went into Advance Auto parts and asked for the belts for an 08 FX35.

Thanks for the write up.

 

Just did the removal along with my lightweight crank. This was good reference for the project. Thanks for the write up.

 

Picked up a 5/8 nut, that measures 11mm thick, fits in perfect.

 

So i just did this mod on my 06. Its not as easy as led to believe. Im not sure how the op car was when he did it, but in no way did the pulley bracket slide out to the right. I had to beat the crap out of mine for about 40 mins trying to get it out... the bushing was no easy task either, as it had to be forced into postion and lined up with a mirror while pointing ur flashlight at it all while holding a screw driver on the spacer while hitting it with a hammer...i was by myself so it can be done. Holly hell that was a B

 

Thanks for the write up, I was all nervous about putting the 17mm bolts back in like they would not have enough room without the extra space... I called z1 and Russ told me what was up.

 

Same here I beat that the stupid bracket silly with a hammer and it wouldn't budge, no even a single mm After 30 mins I gave up. So I'll go over to a buddy's shop and let him have a go at it because for me it ain't happening

 

I loosened up the power steering pump bolts before I actually got mine out.

 

That thought crossed my mind...

Which bolts should I loosen? See attached picture from the FSM - the bolt circled in green is already out. It is 1 of 3 holding the idler pulley bracket on, which oddly the FSM calls the water pump! Thus I assume the two (only 1 is shown) I circled in red also need to be loose enough to allow this sucker slide out to the right Do you have access to these from under the car? I don't recall seeing them from above.

Thanks!

 

I loosened these 2, the one in red is too much of a ***** getting too... Then I tapped it out with a rubber mallet and a screwdriver... Once it budged it was good to go.

 

Thanks I was hoping to avoid the reds ones, but they appear to be what is holding the black PS bracket in place. And the PS bracket is on top of the idle pulley bracket. Hopefully removing the (yellow) bolts will take enough weight off to allow it to slide over once encouraged with the hammer.

After reading this DYI I just assumed once the 3 bolts were out the part would basically fall off the engine since nobody mentioned it getting stuck.

 

I used a 10in. x 3/8in. drive extension and a dead blow hammer. With a little patience and careful tapping, it started working its way out. Then I just hand-made the three spacers with the un-used idler pulley itself. I cut the three eyelets off with a hacksaw, then used a grinding wheel to make them into perfect circles.... I even buffed them with the wire wheel to make them shiny.

 

Yeah it took some back and forth hokey pokey and love taps here and there but mine eventually came off. If you loosened the red bolts it would for sure come right out but thats a lot of pain in the *** getting to them..

I used the spacer that Z1 sent me for free, worked like a champ... Its only like $3 if you need to purchase it I believe. The hacksaw method works though.

 

I got the Z1 spacer... actually ordered the whole kit with new belts and a nice lightweight crank pulley My AC belt snapped last week (after squeaking for months) so I figured while I'm digging around replacing the belts I might as well do this mod by removing the idler pulley plus swap the crank pulley. I couldn't budge the crank pulley either with just hand tools but that was expected - figured I need an air gun to knock that sucker off. Just had no idea the idle pulley bracket would offer up so much resistance

 

Haha I got the same kit, that bolt wasn't fun. I strapped my belt to my sway bar and used a 25 inch breaker bar with the jack handle for a cheater. I was pretty happy with myself when it finally broke loose.

I knew it was going to be difficult though, I had taken apart an entire motor a few months earlier and it was also a bad time.
