ISO: Ring Gear Stop, Chain Tensioner Pins, and Tensioner Shoe Installer

I have the dreaded engine whine and Iím sure I need to replace the Secondary Timing Chain and Tensioners. In reading the Nissan TSB (NTB09-128) for this issue, I see that Tool J-50246 (Tensioner Shoe Installer and Chain Tensioner Pins) and Tool J-48761 (VQ40 Ring Gear Stop) are considered ďessentialĒ.

Iím in SoCal, is anyone here local that would let me borrow those tools?

Yup, those 2 tools sure help. The ones I used were unofficially called "paper clip" and "really big screw driver", in case you have any trouble finding the official ones.

The shoe just pops on and all you need is even pressure. The pin just holds the piston in the compressed position. (Don't forget to remove it, I think a member here posted about a shop that forgot and caused some damage.)

Oh about 12-14" I think. The one I used was probably older than me.

Do you have a manual or automatic? With a manual in 4lo I think you don't even need to worry about holding the ring. Somebody with a manual would know better than me. With the auto it wasn't all that hard to keep it from moving.

Just got the parts in today to do it all over again on a pathfinder.

It's an automatic 2WD. I've read that if it's 4x4 you can put it in 4Lo or if it's 2WD manual, you can put it in 6th gear. If its 2WD automatic, you need something to lock the lock the flywheel. I've also heard a screwdriver would work (as you also said).... so I may have to go that route.

D'oh!

I saw the thing up by your user name that says red 4x4. Sorry, I didn't think maybe it's wrong or you're working on somebody else's truck. (Like I am with the pathfinder... double d'oh!)

I really don't know about that, maybe you do need the lock tool in that case.

Yeah, I just bought a 2007 S 2WD at an auction for real cheap. I'm reviving it for fun and I will probably give it to my niece who needs a car.

you dont need the ring gear stop. i've done 10-15 without. paper clips work for the tensioners. ive always used the tool to install shoes cause it makes it east.

How did you secure the flywheel when removing the crankshaft pulley and camshaft sprockets? Since I'm working on an Automatic 2WD, I won't be able to put it in 4Lo or 6th gear.
