262XP Case Swap & Compatibility with 254XP 257 261: Part 1
Husqvarna 254XP 257 261 262XP family identification, comparison, compatibility along with a full teardown of a 262 XP that has a broken bar side rear mount. Every single part is taken apart, including case splitting, crank removal, and bearing removal using an oven to expand the cases.
Part 2 will be the re-assembly with a case swap, setting squish, possibly doing a base gasket delete for more compression, and possibly some cylinder honing or scuffing.
If you have a chainsaw in this family that needs repair, this will probably help you find out which parts you can substitute. And if you're interested in Husky 2-stroke engines or chainsaws in general, you might learn something new. But if there's something you can teach me back, please comment!

Lowered Footpegs for Tall Guys! Vanasche Rally Peg Install and Review on KTM 530 EXC
Enjoyed this video even if it doesn't work for me. Short history, MacBook Pro late 2013 and Apple TB monitor, new early 2014. Bought a late 2023 MB Pro M3 and used a TB 2-3 adapter for a year with no problems and of late sometimes would not wake up, then not at all with either the 2013 or 2024 MB's. On the 2013 the magsafe doesn't light up anymore. I tried a rear TB cable and the adapter to the 2024 and without to the 2014 with either. My understanding is the rear TB's do not work on adapters without the magsafe charge working. If the rear TB's are on the same board as the main TB & power cable, why would that be the case? Does your TB 2 to 3 internal cable replacement require operational magsafe power? I don't need the magsafe power and if this internal hack works without magsafe maybe I can keep the old monitor working. Is there a way to even see if the thunderbolt display turns on since there is no power switch (externally or internal) Thanks in advance.
Can you use a bench-top power supply to do this?? I don't have the computer power supply like you have. Thanks for any info
@@Sisko125 oh yeah bench top is preferred. My ATX power supply is just a DIY version of a bench top PSU!
@@colindgrant THANKS!! I just got. Gooloo 4000s that will not charge for Christmas getting a E4code and beeping. Have a diagnostic usb and like you no amp, no watts. How do I set my power supply to do what you do? I think I can do a usb to clip at home I have so many laying around that I can sacrifice to do this. Thanks for any help with the ps adjustments!!!
@ it should just be a matter of setting volt and amp limits on your power supply, just like I did. But if those power packs are new, I wouldn’t try to fix them, I would exchange them!
@@colindgrant Yeah i can’t exchange it I bought it from a surplus store and they don’t do exchange or refund. This was a brand new unopened box so I’m stuck with it so I’m tempted to revive this booster!
Great video thanks and God bless
Tried doing this, used the same batteries as you. Used solder to weld them in place. Now im getting Error 7. Did yours work right away?? My roomba is model 805
@@Immigrantlovesamerica hmmm. Yes it worked right away. Did you check the voltage of individual cells to ensure they are balanced? Did you check overall pack voltage to ensure the series V is the sum of the cell V’s? Are the center taps on the circuit board soldered in well? I can’t think of anything else to try.
@@colindgrant Thank you, imma go back and recheck
I really hope these fit my 2008 450 XCF…I need lower pegs

How hot did the battery get during a charge?
@@solemann3 Barely perceptible.
Great video. Wish I had seen this before.
It would be a good idea to clear the charred/carbonized "burn" off the board since it can be conductive.
@@stevetech7335 you’re saying the fiberglass/epoxy/whatever core of the becomes somewhat conductive when charred? I didn’t realize that. Can you explain more?
Hi, thanks for sharing your experience how to fix it. I have 3 devices. one following your method i manage to make alive again. but other two not really. Once is up to 10-12v and plugged in fast charge usb c 65w laptop charger it just keep son 25% mark and does not get full charge no matter how long its left. also fast charge icon on the device its solid red (not white as it should be). not sure what should i try next.
@@reggaeregis look at my other NOCO video that has ‘balancing’ in the title. Probably worth looking up that red light too. I don’t remember of hand.
My genius pro 50 died one day, had it in my battery in 10 amp mode and left it for a few days, I came back and dead. Really annoying as it was brand new, so I took it apart hoping to see an internal fuse and if there is one then I do not recognise it…. I expected it to be obvious cause of how big it would need to be. However all I know is how to solder, not how to diagnose and even then it’s so complicated in there without a schematic you have no chance. Everything looks perfect, so the faulty component is hidden.
Bummer! I've never used one of those or seen inside. Good move looking for a fuse. It may be smaller than you think though. Here's a video that is much like your situation. I had a device fail, I couldn't find a fuse and bought a replacement, it failed the same way, and then I finally found the fuse! ua-cam.com/video/vJJl3NoeiUc/v-deo.html
Thanks gonna have to try this I'm 6'8 got a 701 love the bike but do struggle with size. Would love to ride them trails. They look epic. 👍
I’ve got two tall friends running them on 701s and they love ‘em.
Very helpful video, Colin! I had a similar issue with my bag, the turn lock connectors were too loose to stay closed. I used the rivet gun from the front side of the bag and cut a scrap piece of aluminum from a can to act as a backer inside the bag. A 1/2" long, 5/32" pop rivet was perfect for securing the connectors.
Awesome! Glad to hear you were able to repair it. I just put 10+ hours on this thing and it's going strong!
Sir, this video has helped me so much! I spent many hours to search for a DIY DC LOAD but every project has (serious) flaws. Thank to this video I now want to buy a chinese DC load and replace components for genuine ones. :)
Saw this video today, i had a similar idea for my thunderbolt display, but more like plugable one not the cable coming out of the display. for which i even bougth 40gbps coupler which didn't work coupling, so the project got stalled. i dont want a again a cable coming out of it, i want a thunderbolt female port, which is not there anywhere.
Have you done this on a Cobra JumPack XL? I can't get either my regular or the H20 version of them to take a charge using either of your methods yet. Thanks for these videos though, they are wonderful!
No, unfortunately I'm not familiar with that model. Good luck and report back if you figure it out!
how much voltage should it rise to for a gbx 155
That should be a 4S LiPo battery, so I would target 12V (3V per cell), or up to 14V (3.5V per cell) if needed. You'll probably see it wake up even lower though. As soon as you can, switch to regular USB charging, and let it charge itself. It knows how to stop when any individual cell gets too high. Good luck.
Yeah, I guess there is a reason why the more expensive loads like the Siglent SPL1020/ 1030x loads are a lot more expenisive, using a few more MOSFET’s rather than 1. I guess you get what you pay for, I have both, the simple one that you just fixed, and then I got the Siglent load. You definitely get what you pay for. The cheap one served me well enough, but combined with the weird GUI, and no dynamic load testing (even though the software should have been able to do it), that cheap load has found a place on my shelf reserved for equipment I don’t use anymore.
Couldn't agree more, I'm definitely ready for a 'real' load tester, just looking for the right deal to come along. This thing has been surprisingly useful, but I'm ready for a tool that doesn't need constant monitoring and a fire extinguisher!
Amazing ! 👏👏
Thank you so much. The video is so detailed and well shot. Regarding the replacement cells, I thought that if you put LiIon Cells in series they need to be protected cells? Or is the charging circuit measuring the voltages of all 4 cells ?
Great comment. The answer is it depends. These days cells are made really really consistently and most manufacturers do not do individual cell measurement in their OEM battery packs. Instead they deploy a heat sensor or two, and depend on that to detect any anomalies. In this case, the Roomba board is able to see the voltage of each cell (note the folded nickel strips in-between cells 1-2 and 3-4 as well as main contacts on 1 and 4). I used brand new high quality cells in series here. They may drift in balance very slightly over time, but it's standard practice to use modern unprotected cells in series even with only thermistor monitoring.
thats pretty cool
Thanks!
I’m glad you found it helpful. Thank you for your generosity!
Thank You so much! My NOCO died right before my road trip and this revived it. I'm assuming the light was accidentally turned on and ran the battery completely dead. Here are few helpful tips to help revive the NOCO boost pack. 1. Make sure you have a decent wall adapter for the USB-C cable. A 1amp USB wall adapter may not supply enough power to continue charging the boost pack. 2. Continue to charge the boost pack with the USB-C cable as soon as you take the boost pack off the power supply. The voltage on the boost pack will or may quickly drop as soon as you take it off the power supply. If the voltage drops to much, then the USB-C cord won't be able to continue charging the boost pack.
Is the red cable possible to be replaced? My dog chewed mine and I’m wondering if I can just get extra 8 awg wire and replace the bad cable? Thoughts? 😊
@@iflo92if not easily. It’s leads directly to the battery where it has heavy soldering that’s tough to do without that right equipment. And butt splicing is tricky due to the high current it needs to handle. It needs to be a really really really secure inlets low resistance connection. The stock 8awg stock cable is honestly only sufficient because of these super secure connections and very short length.
@ thank you I was looking at different connectors to see if I can fix it. I appreciate the response:)
Thank you...great review 👌👌👌👌 I m gonna put this on my 790 adv
You won't regret it. They're really great parts.

What a great update to the thunderbolt upgrade! Thanks as always for the highly detailed and thorough walkthrough 🙌
Just got me a thunderbolt dispay on Sunday after watching your video and here I am again thank you so much gonna do the USB-C conversion soon
Serendipity in action, just collected a second thunderbolt display and thought, somebody converted this to USB-C right? Turns out this video was uploaded 9 hours ago. Thanks!
first
Hey I just bought the Mac mini m4 and I found a thunderbolt Apple display for a good price. If I replace the original thunderbolt inside the display to one that has type c connection on the end, do you think that,ll work and still be able to use the speakers built into the display as well?
Yep, if you do what I did in this video, it'll all work!
How do I go about doing this on a gb40 it has a USB micro instead of a USB c input
It should work the same way. Just need an adapter for micro to alligator clips.
my display will work on my 6,1 trash can TB2 but not my 13,1 TB3 adapter.
Original NOCO Car charger is 12V 65W, this is what you use when normal charger dont work as it forces 12v and not "auto select 5v" as the wall charger does when low on power. Just use the manual and what comes with the charger, no need for anything else.
Didn't have a triangular screwdriver bit or a torx bit that would fit, so substituted it with a hacksaw. Took an hour to remove the back cover to avoid damaging the internals. Wish I watched this video before the one for the GBX55.
Thank you m8 took the leap and bought one of these on ebay followed your video and its working perfect
My Ego has the same motor symptom. It even spins occasionally. Unfortunately, none of the TPH4R008NH is short. The fuse is fine too.
If it were me, I would replace all the mosfets anyway, and then look at the trigger next.
It worked for me thanks
@colindgrant could you trickle charge the NOCO using its negative lead clamp instead of via the usb port?
No, the negative lead is switched internally, it's not directly connected to the battery.
@ thanks.
This migth be due to you are using a mac charger. Their supply logic is drastically different from others.
@@yaosun9431 kind of. The Mac supports USB-PD, the charge protocol for USB-C. So they’re more compatible with other manufacturers than ever. However, like any manufacturer, it’s up to them to decide which specific PDOs they support. This Apple charger skips the 12V PDO. It goes from 9V to 15V. It also supports extra modes that only apply to specific Apple products, that’s how they do 140W for the M1 MBP it shipped with, using a special USB-C to MagSafe3 cable. That doesn’t apply to this video though.
@@yaosun9431 at 15:15 you can see how the Apple charger and the NOCO charge PD controller negotiate to use the 20V PDO.
Is there anyone in the UK that can repair these NOCO I ain’t got the skills or equipment to do this. I have the GBX55 just out off warranty Thanks
Every video or writeup i see about these always has the charging port as USB-C... My GB40 is evidently one of the first versions or something because mine has a micro usb instead. I assume your method will still work the same for my unit? (just substituting the usb-c cable with a micro usb cable)
@@motosaki404 I have a video on the GB40 as well. I think it’s micro USB on the GB models. I do think this method will work with the micro USB connector.
I replaced the tank vent on my 460 (it would stall constantly but startup again if I loosened and retightened the gas cap) but now it seems to really go through a lot of fuel when used.
@@Lariat8 my guess is that the high jet had to be tuned extra rich to deal with the vent restriction. Now that you’ve dealt with that vent, try adjusting the high speed jet more lean.
@@colindgrant Thank-you for the quick reply! I have the correct adjusting tool. I've however come across a couple different sites that explain different ways to adjust the high jet. One explains to close it and adjust it 'x' # of turns out and another explains it as I was used to doing years ago on a cheaper saw and that was to run it and adjust the high jet while at full throttle. What are your recommendations? TIA!
@@Lariat8 number of turns only gets you started. Low and high are the same: you’ll need to lean it to the highest (smoothest) RPM, then richen to the point of four-stroking (sounds like a miss). When it doubt go rich. Rich will cost you fuel and power. Lean will cost you piston rings, as in this video!
@@colindgrant Thanks for your reply! I have already replaced the can and piston (came as a kit) on my saw after 8 years of use, the original can had a foundry defect on the top that let go (aluminum shrinkage due to a cold pour spot) I did however notice the same condition of the ring as above. I will stick to rich! Thank-You (other than all that I like these saws better than my Stihls!)
@@Lariat8 I’ve only ever worked on Huskies but I already prefer them!
Bro with all the M class macbooks out and people trying to get rid of their thunderbolt displays why not make a kit fopr people to replace. I sure would buy it!!
It depend on the voltage level of the load that you connect to. On my 2024 Model 3 Highland I got 64.5W on each USB C port. But on the manual it is specified 65W per port x 2 max or 45W x3. Please note that it depend ALOT of the cable electrical resistance too. A poor quality low power cable can loose up to 40% power!
Amazing job sir. You just gave ideas in how to fix mine 😁
