don't forget to take the bolt out of the tensioner when the gap is set. very informative 🔧👍

The 300zx, is one of the easiest timing belts replacement. On any car I've ever done! The water pump is also separately, if you ever need to replace it. Nice video you guys 👍

[@SoloKyoto]

You have never changed one on a NA Miata then, I got to where I could do it by myself with no timing light or anything fancy in less than 45 minutes.

Easy seal extraction tip. A small self tapping screw or drill small pilot hole then small screw inserted partway into seal. Lever under screw head with forked tack removal. The seals, where their rubber makes contact with camshaft and crankshaft should be lightly lubed with oil before insertion. 😎 I also had to replace the foam perimeter dust seals and some rubber bolt grommets on the timing belt cover. Pretty good vid and the paint and color combo is awesome.

[@elibarnett4399]

I watched your video on the stage two clutch replacement and I have to say it's the best video that I seen on line and it helped me out alot and in the future I will use your videos for a reference or help guide ,you guys made everything crystal clear and it made working on my 95 Z so much easier and understandable and made everything go off with out a hich. Thanx alot bro and you guys keep on your grind and stay up .

Im here for the people who try to do this with the engine still in.

[@slidewayskenny6925]

same here, i wanna know how to do this with the plenum still on, aka holding the cam shafts in place while pulling cam gears off

[@SoloKyoto]

@@slidewayskenny6925 impossible, you have to remove the valve covers and in order to remove them you have to pull the plenum.

[@SoloKyoto]

@@slidewayskenny6925 actually not impossible but it would be Ridiculously hard and very very little room to get to anything with the engine still in the car.

[@slidewayskenny6925]

@@SoloKyoto false, i have already finished doing the full 120k maintenance including rebuilding the power steering pump and installing a new radiator. so therefore it is not impossible

[@SoloKyoto]

@@slidewayskenny6925 That's why I said it isn't impossible but just very hard.

[@ElSesh]

On the concept Z wiki it suggests for the tensioner to be 3.5mm - 5.2mm and you should rotate your engine 720 degrees twice and recheck the tensioner. You should definitely be good. Also my tension is always coming back to 5mm. I want to readjust to be within spec but I’m scared I may loosen the belt too much.

[@frog7118]

AC tension pulley bearing froze up and broke my AC belt. Watching this video around 39:10 showed me how simple it is to replace pulley, Just loosen the nut on the front and slide it out bottom of the slot. I got a used pulley off eBay and I just back off the adjuster bolt and slide the new setup into slot, snug the front nut, put on the belt to hold pulley in place, loosen nut and adjust to proper tightness of the belt. Thanks for a clear view of this assembly.

[@ZBruhzchannel]

Glad to be able to help!

[@cookies4life63]

I picked up 92 tt about a month ago and I got everything from concept Z as well, first time doing a timing belt with a friend who knows more then me. Can’t wait to get my shit running after sitting for a few years

Great video, when installing those cam seals I've always lubricated the seal before installing them almost the same as when you lubricate the oil filter seal before.

[@ZBruhzchannel]

Love it!

[@brotharuss]

The spec is 3.5mm - 5mm. Note: A 4mm allen key is 4mm from furthest point to furthest point...so shoot for bareley being able to spin a 4mm allen head in the auto tensioner gap after two full crank sprocket rotations.

[@vernonjackson6387]

Great video guys. I needed the detail. Thanks for making me feel more at ease in doing my 120k service.

[@ZBruhzchannel]

Take your time and good luck!

[@3lija11]

For the crank shaft/ sprocket (I'm guessing that's what its called ,new here) at the very bottom @6:45 , i think you skipped showing the install of it , is there a video i can find for that or a forum on how its done? This is my first project car and i don't have any mechanic buds (im solo) Also your videos have been helping me a lot man thank you!

[@ZBruhzchannel]

For the Crankshaft sprocket it's very simple, the only thing you want to really focus on is the washers that go with it. Once you put the washers in the correct area all you do is slide the sprocket on. Cleaning the crankshaft with a scotchbrite free of rust and lubing the inner race will help it go on smoothly.

Hi Jeremy, i just picked up a 90 NA, what do you mean by all this?

[@jeremythompson6822]

@@danmazz8733 Nissan overengineered the 300zx. You will need to do a lil research but whenever you have the engine out its a good idea to do all that

[@michaelbarrett8803]

if you have the valve cover off you can just loosen up the camshaft end cap and remove the seal and put the new one in. If you do loosen the camshaft end caps you must put a little RTV on the base of the end cap.

[@ZBruhzchannel]

Thanks for the insight! I'll remember to do this next time!

[@Tastys14]

Hey man, I hope you can reply Where is the belt supposed to ride on the sprockets? After cranking a while, it ends up damn close to the backing plate. Not sure where I went wrong

[@ZBruhzchannel]

Belt should be, somewhat ride onbthe middle of the sprockets, depending on what belt you purchased (if not oem) it way be a bit wider.. Also the belt will somewhat center itself after a few rotations. I typally male sure as long as the belt is centered on the tensioner you should be okay

[@chefswole]

do you have a video of your painting of the water pump? or is it simpler than I think? thanks!

[@ZBruhzchannel]

Very simple, just cover up the rear seal part with tape and the bearing part where the spindle is on and paint with high heat paint

[@Junkitup]

Robies da professional Thank you

[@spicythai2000]

I see alot of videos about the timing belt and they have the marks on the belt and the dimples line up. I used gates timing belt and it doesn't align perfectly but not a tooth off. So I kinda baffled how they have it so perfectly line up.

[@customzdream]

Awesome video. Very informative. Thank you men. It will help a lot.

[@slidewayskenny6925]

how would you hold the cam shafts in place if the plenum wasnt off?

[@ZBruhzchannel]

I mean people have made contraptions to hold the gears from moving etc, but it way easier by just taking the plenum off. We have a video on how to take it off if you need something to reference!

[@codiehall5565]

How would you go about removing a UR aluminum crank pulley? I got jaw pullers, but don't really like the idea of using one beings the aluminum is a softer metal then the stock steel crank pulley.

[@ZBruhzchannel]

I have used pullers for a while now and I believe to my knowledge that is the easiest way to go. Just make sure the teeth are on the pulley and be easy with it

[@Mario-et3tp]

Wow im rechecking my timing after this video while it's still on the stand I didn't put the pressure on my tensioner when I tightened it

[@ZBruhzchannel]

Good looks!

[@GojiraZzz]

There are two TDCs make sure it’s compression not exhaust stroke

[@davekelly7184]

It has been mentioned that the bolt used to set the tensioner should be removed after final assembly, can you explain please?

[@ZBruhzchannel]

Once tension is set, you must take the screw out so it is not pushed out due to vibrations. If it is left in it will unscrew and damage the belt

[@davekelly7184]

@@ZBruhzchannel Thank you, would like to know it's purpose. He explained that he put approximately 15lb's of pressure on the belt before securing, so how does the bolt affect the tension?

[@ZBruhzchannel]

@@davekelly7184 the bolt is used to keep the tensioner from fully opening to its furthest point. It's a hydraulic tensioner. So once the proper amount of tension is placed and the spacing between the hydraulic pump is set and the the part is fully bolted down removing the screw will have the tensioner hold its position

[@davekelly7184]

@@ZBruhzchannel Brilliant. Thank you sir. I have owned my ZED for 17 years with very little use, so would like to change the belt before re commissioning her.

[@Mark-el3kz]

Helpful video. After setting the tensioner gap to just under 4 mm, I rotated the engine 720 degrees, and the gap increased to just under 5 mm. Is this ok, or did I do something wrong? The gaps were the same after letting it sit for a week. Thanks!

[@Mark-el3kz]

Also, when I turned the engine back to the starting point for belt install, the tensioner gap was still under 4 mm there. So the gap ranged from just under 4 mm to just under 5 mm. I tried resetting the tensioner, but the gap range did not change. Is this ok or a problem? If it is not good, how do I fix it?

The belts should have marks on them. I highly advise not to put a belt on without the marks. These pints are crucial for proper timing

Aye I got a question about the intake cam gear. So I'm reinstalling it right now but when I was torquing it down the entire gear didn't move but the screw made this weird jump and now the cam gear after torquing it down is turned. I was able to line the markings back up to the back plate but idk if that fucked anything up. Do you know if the intake gear is fine or did I fuck up badly

Some people say it should be good but I don’t wanna risk it not being spec

@Rafael Camacho is it a Nissan oem part? And if it is the best way to set it is by following the process and using a prybar to help set the tension

Are you literally saying the only way to pull the camshaft sprocket is to split it in half?

[@ZBruhzchannel]

No, there are other ways such as drilling and tapping two holes then use two bolts to help pull it off. We have found it much easier to cut and get rid of if there is rust.

HELP!! My engine and transmission are still connected together inside the car. i was tempting to do the timing replacement and took tension off the belt but forgot to put the engine at TDC. so some how i put the belt back on with some tension and rotated the engine from the crank trying to get to TDC but then forgot that i should have put the car in neutral. so i was rotating the engine while it was in first gear and now for some reason i cant shift the transmission out of first to neutral to rotate the engine to TDC. ANY IDEAS HOW TO FIX THIS? HELP!!! @Z-BRUHZ AND ROBBIE

First thing you should try and do is count the cogs on the belt while it is still on the car. I hope none of the gears turned on you once you removed the belt because that can and will be a huge issue
