- This is a how to video on the steps I take when I split cases on a Honda Trx400ex this is the same bottom end as a Honda Xr400r. This is a bottom end from a 99-04 400ex.

Subscribed n thumbs up of course when the guy on the camera knows what he is doing, thankyou Sir you are the best !
Thanks for the sub bro I appreciate it
Thanks great info
Part 2 of that is out too bro. Installing new crank bearings.
Keep up the good work I need my bottom and redone to gonna start tearing it down
Before you buy any parts lmk. I have cranks, cams, and some other stuff too
Killer bro can't wait to c part 2. Keep killing it my dude. PEACE
This quad is all this week bro
Nice to see someone using good parts, not like some stuff I see.
Oem when possible
Man of course I’m gunna smash that subscribe button it help me so much thanks
Thanks bro. Trying to get the channel up there. I'd like to start building quads to give away.
Part 2 is putting this engine back together
@@garagemcmatt would be sick
@@garagemcmatt yep ima check it because I have lots of part coming in
@@HaydenForgues have fun bro 400ex's are easy and fun to work on
Great video
Thanks bro I try
Do you have to pull the flywheel to split the case? Say if you were just replacing gears in the trans?
You could leave it on if that's what you wanted to do
Hey man the bearing on the clutch side supposed to spin on the crankshaft slightly?
The bearing on the stator side is a sweat fit. The bearing on the clutch side is slightly less tight but shouldn't just spin freely on the crank
Oh ok
Thanks
Would this be similar to a 1987 250x apart and put back together? I could not find a video of splitting the engine to do a total rebuild.
It would be the basic idea of it but not something you could follow for a 250x tare down and rebuild. Same principle tho. I have a 87 250x parts bike if you need something
@@garagemcmatt thanks do you have an email?

Do you have to split the case to replace the shift shaft
Yes you do
You can see why in part 2 of this engine
I recently bought a bottom end to rebuild but don’t know the year of it, is the stamping on the flywheel side any indicator to the year
If it's a non reverse engine it's a 99-04. The only difference I know of in those years is one of the bearings is different but any good bottom end bearing kit will come with both style bearings. You might be able to find out the exact year by those numbers but I've never tried
Do you know the size of the oil line dowels are?
Not off hand. I'd be guessing but 3/8. You can find the schematic on rockymountainatv.com
How did u take the bottom end off the frame? I’m having trouble with the rear mount bolt gettting it out
The pivot bolt that goes through the swing arm? They get seized all the time. Your gunna need to soak it a few times with pb blaster for a few days and either use an air hammer, a slide hammer, or cut it out but try all the other options before cutting it. It is not fun but keep at it and u will get it out
I just bought a 2001 and it's rough. I'm wondering if theres supposed to be a spacer between the case and swing arm on the rear pivot bolt. I see at 5:18 this one doesn't have one. Is it supposed to be like this?
You mean the spacer that goes into the cases or the 2 that go in the swing arm?
@@garagemcmatt Between the swing arm and case, I made a video of it. ruclips.net/video/625W08C2UbM/видео.html
Also this thing is a 2001 (10th digit of VIN) with Reverse so I guess the engine is newer. Is the wiring the same between the years? Because it's wired to jump the solenoid and drive, none of the controls switches function and stuff is disconnected. I've had this less than 24 hours and already ordered a ton of parts and been looking thru your videos.
Thanks in advance for any info.
@maglight2006 the reverse came out in 05 and the wire harness and cdi are different. When I get home I'll check out your vid and see if I can help
@@garagemcmatt I see it now, it's the inner race of the swing arm bearing, the one on the right side extends all the way to the case. Mines gone, they left it out. This ones going to be a fun project.
@maglight2006 yes those inner spacers come with a pivot bearing kit and there are 2 of them and the one on the right side is longer. If your bearings are good still and u need that spacer only lmk I always keep take off parts like that
How much did the repair cost
The new crank and bearings? 3 to 400 for the parts being oem
How much to do a complete reseal ?
Depends on what shop you go to. Some shops now are $120 an hour
@garagemcmatt oh ok thanks. About a 2 to 3hr job if motors already out ?
@brianbaker2484 it all depends I've done 400ex engines in a few hours before then had some that took all day. You can email me idk where your located but people have shipped me engines to build for them. Garagemc549@gmail.com
@@garagemcmatt message sent. Greatly appreciate it.
I do that to with the bolts, like to put bolts back in the same holes they came out of even if they are all the same. It's like putting them back in there homes, lol
Lol. What are u to good for your home !?
@@garagemcmatt every bolt has a home, who I'm I to re home one, lol
@@johnbruzzi4381 lol
Mines an 06. I have no reverse lol
Broken or it has a 99-04 engine on it?
@@garagemcmatt definitely not broken. But I've followed the protocol for reverse and it doesn't shift into a gear. I myself never changed the motor so I don't think so to be honest.
@@kodeland7729 would be tough to take a guess at what it could be just hearing about it. I'd start with the reverse cable and how it goes together inside the engine at the clutch cover
@@garagemcmatt it very well could have been removed by previous owner. I'm the second so I don't really have the right to say I know for sure
I thought the 416 was bored out to 87mm not 86.
85mm is stock, 86mm is a 416, 89mm is a 440, and 89mm with a stroker crank is a 465 in most cases
@@garagemcmatt oh okay, I thought 86 was the 406. My bad.
@@Ninoo187 it's all good bro. If you break it down the math don't make sense but that's what they call the sizes
@@garagemcmatt well I bought a kit that was advertised as a 416, and it came with an 87mm piston that's why I'm asking. Thanks to your videos I finally got to finish my build yesterday.
@@Ninoo187 that's cool bro I'm glad it helped. That's what it's all about
Probably that " mechanic "did the porting
That's what I thought
BP didn't touch that shit I got 2 heads in the garage done by them and they wouldn't dare idk who done that shit but damn it's not that hard to do more time consuming then anything somebody had no clue what they was doing
It was from BP in the beginning then someone that had no clue touched the intake side. Looks like they let a beaver loose on it
To many scamers out there it's sad I get atv an bikes that people have had bad work done I fix them the rite way it just sucks money don't come easy and your with out your wheeler for mouths it's just f Ed up
Yeah bro it's bullsh*t for sure.
