240SX KA24DE Engine Rebuild Series pt.1 Teardown 

Where can we get a copy of that repair manual?

IDK if all of this necessarily applies to the Japanese KA24DE, but on the Mexican version (Frontier and Xterra) the harmonic balancer nut can be removed with a breaker bar and the power steering belt looped over the AC compressor and the extra length wound over itself on the crank pulley. The belt's tension will keep the crank from moving. As for removing the harmonic balancer, I opted for the duck foot style of tool (also used to remove steering wheels) instead of the claw style tool used in the video. I just had to buy a couple of M6x1.0x75mm bolts and two sets of washers separately from Ace Hardware to thread into it to make it work, but afterwards the harmonic balancer popped right off the crank without much effort. The 24mm intake and exhaust cam bolts I used a cordless 1/2" impact for, and the 19mm chain center sprocket as well. The impact made quick work of it and also didn't spin, so it kept time while eliminating much of the struggle of two-wrenching it. The head bolts I used my 1/2" ratchet with a 1/2" to 3/8" adapter and 3" extension to utilize my 3/8" 10mm hex bit; I loosened them in 3 stages while following the torque pattern in reverse. I figured it would place less stress on the head instead of using the impact for that too. The casting of the 3/8" bit should be narrow enough to clear the wells to reach the bolt head, btw. The 1/2" bit on the other hand will likely be too thick to reach the bolt head at the bottom of the well. Hopefully these tips help anyone seeking to rebuild one of these engines. I learned to rebuild the KA in my 240SX when I was 16, so doing it again for my Xterra is just bringing back the familiarity of problems I've encountered before with the better tools I have now to make the job easier.

I finally got my first s14, your videos are gonna help since I started watching your series last year lol. I have to replace my subframe bushings like you did, Waiting for the next ep!

KA Bottom end weak points are piston rings. You’re able to use the rods and upgrade pistons. I’ve build 400hp KA with stock rods and WiseCo pistons

love the build man! iknow it was a year ago but you dont need to get a crank balanced unless you are doing like 900 to 1000hp but it wouldnt hurt to have them look at it check clearance and polish it

The very first step for me is a breaker bar on the harmonic balancer nut. I then turn the engine over with no coil wire attached. Then I do whatever else I want. Like timing chain or remove the engine or whatever

Hey, thanks for documenting your repair videos. They were a big help for a timing chain job that I recently finished up with the engine still in the car.

You were right about that timing chain guide. Just found mine in the oil pan...

Mad respect! Very good work! Want to see more of this rebuilt.

you probably already guessed it, but dont forget to bolt your timing covers to your block when you get it decked. Gl man

This is inspiring. Good luck with your build!!

Thanks for making this kind of videos bro, Iĺl be doing the same on my 91 240Sx

Thanls for logging this👍. Now I know what I'm in for.

I've already rebuilt my ka for turbo je pistons ,arp head studs,clevite bearings new oem timing gears and such white bunny clutch upgrade and a weir full spool. Hopfully I can run 10lbs of boost no problem

I know this is a a super later comment. Next time you do a bottom end. Pull main, and rod caps at the same time. Pull crank out, will make removing rods, and pistons way easier.

Enjoying the series bro

Issa 10 mm 12 point socket for the oil squirter. Use a 10mm long socket to smack the oil dip stick out.. also replace your woodruff crank key with a new one.

Awesome vids bro, defintely deserve more subs than you have rn. Count me in.

Awesome tear down

Keep up Good woork boy from mexico city👍👏

I gotta rebuild a ka24de as well soon for a s14 turbo build soon. Looking forward to watching u build one

You're lucky af you pulled the motor when you did. Imagine if that chunk of piston popped out running...

use the black links to set the timing with the dots.

Happy 5k

Welp time for forged internals

Great vid

also, what tools were absolutely needed for certain parts of removing things from the head/block?

Can anyone tell me what manual he is reading from

Wiggle that dipstick it will come out, just a O ring holding it in.

Get some race crank bearings from enjuku

Where did you get the book from ?

i have an extra motor thats just going to the builder. lol

I was wondering how much is a machines shop cost to balance on piston and crank shaft also the block too, like what needs to be done to the block while it’s being resurfaced? 🤔 I have an 1992 240sx ka stock and it needs new crank bearings dose make a wobble noises. Vibrating going on when I start the engine. But planing on having it rebuild. Need some guidance.

It helped

My ring lands were like thats before my rebuild

Vg33 manual trans can bolt up to the ka?

What Ecu did you use?

Update?

what manual were you reading while pulling it apart? i need it lol

I need a copy of the manual and does anybody a have a ka24de head they dont want i need one my 240 doesnt have a head on the block

Hey can you let me know where you got your engine stand

what transmission are you running?

Where the content at broo??

Good work check out my 240sx. I delete emissioin test pipe, heater core and many more.

Dude. Just do SR20 with T25 on 12psi and have a fun reliable car. KA-T is shit. Been there done that.
