Repairing an Old Makita 9609B 9inch grinder in need of restoration.

[@danimkn579]

Dean, I am an electrician in Pakistan. I had makita 9 inch with some fault in my store. With the help of your videos I diagnosed its fault (which was gear and bearing issue) and solved it. Spending my time on hours long video worth it. BTW makita 9 inch grinder is beast, I believe it still gonna give me more 3-5 years at work.

[@JakeStreisand]

Sar pls open bob

[@TheFallen-xi2ir]

This is my first time watching one of your longer videos from start to finish (I normally just watch your shorts) and I am just damn impressed with your technical knowledge and finesse repairing tools. You're the man Dean!!

[@michaelmcpherson4130]

i enjoy see old machinery geting fixed

[@jamesriordan3494]

Like new ! 🙌 Very impressed by the long term quality of the old Makita plastics

[@leonardpaciora5039]

Great tip! I would have never thought of the hot and cold. Thanks Dean!!!!!!

[@ElRel]

These damn things built Ireland and the UK. Super tools.

[@chris7662]

i'M GLAD YOU TAKE THE TIME TO DO THESE VIDEOS.. vERY ENGROSSING.

[@drearyday1888]

I have one of these. I've used tools all my life and this grinder is the only tool that genuinely scares the pish out of me. I'd rather juggle chainsaws.

[@plunder1956]

Is that a 2000W motor?

[@zaxmaxlax]

​@@plunder1956Probably or more.

[@ElRel]

They are terrifying when you aren't used to them. When I was a young lad back in 1988, I was using one to clean out pointing on stonework all day. Towards the end of the day my arm was exhausted from holding up so much torque at upper chest height. As I let go of the trigger I let it swing down by my side - there was no braking. I still have the scar on my thigh:-)

[@tonybr2469]

I would never and never have used one of those without a guard they are lethal safety first guys especially with that animal😂

[@Dustin_the_wind]

I would fairly say, that your concerns were founded. This thing is designed to change lives in a half second. Gets the job done, even if it's an accident. Way to face the peril fellas.

[@CEO786]

Brilliant video - really enjoyed this one

[@67sss]

The best how to video out there. Well done!

[@Jetpac74]

Nice Sunday video Dean - quality diagnosis as always. Cheers

[@AnthonySmith-hr2kp]

Nice job bringing the 9 inch grinder back to life. Mine still has the guard on it. Good job Dean

[@madeljacky]

My dad bought one of those grinders around 1978, we still have it although i have put at least three pinions in it and two crown wheels over the years, no soft start on these boys, you hold on tight when starting them

[@jasonbuckler190]

Beast of a machine! Nice work!

[@stoffes]

beautiful repair thes old tools worth repairing i feel strong for em!

[@OmegaGamingNetwork]

One of the things I hate about plastic clamshells today are screws directly in plastic. The heat press inserts fitment and reassembly was just so much better.

[@wastelander69]

Your a master of the magic arts Mr Dean thank you for sharing really enjoyed this video cheers take it easy

[@tomalley798]

Good as new. Ready for another 💯 years

[@stoffes]

grinder is old as me still going its a thing of beuty ! 😍

[@Adam-gi1yl]

Love 2 c older tools bk 2 life 👍 Nice work 👍 👏

[@stuart6973]

Brilliant video 👌🏻

[@liftrucs]

Brilliant job, I still own it's twin. When they made stuff to last. The correct term for the key is a "Woodruff Key".

[@dennisbishop3842]

I would have never remembered that term if you hadn't noted this. My brain cells are leaking data.

[@justarideout]

I started work as apprentice fitter on 30th December 1956 and had bloody keys imprinted on my brain, they still give me nightmares

[@petegraham1458]

Nice my Father in law had one of those they are a workhorse!

[@amcluesent]

Nice adaptation of grinder into cut-off saw.

[@DaveGreeneramblingcarpenter]

Possibly the best grinder ever made, and with the safety delete aswell just like my own 😂

[@tonydaddario4706]

Sweet, another twenty years of use.

[@mickweatherall2158]

Loving the vids and I have learnt a lot cheers Dean. The flanges should be equal in diameter and cover at least a third of the wheel. I've done too much grinding with 9" grinders and there's no feckin way I'd use one without a guard but it's not down to you how it's used.

[@Dustin_the_wind]

Nice job big fella.

[@marcelsmit8789]

wow, I have never seen this ice cube trick, heating up the part is a familliar option, but coooling down the shaft ?? 👍👍

[@deandohertygreaser]

Yes 👍

[@Jim_Newlands]

That thing is bringing me out in a cold sweat! Looks bloody lethal 😬😰

[@deandohertygreaser]

They are like this

[@nelchan2421]

28:47 trigger cover finally my tern after a long years

[@dazer123]

I might be a bit stupid here but when you removed the old cable the live (brown) was at the top but you reinstalled it with the live at the bottom so I guess they are not polarity sensitive then

[@conorhastings7319]

That’s the tiniest lil keyway that’s so crazy. I’ve lost ones much bigger than that, shit made me anxious when ya pulled it out😂😂

[@richiejames928]

Will now more than likely outlive the newer versions of the 9inch grinders. runs like new!

[@ashleybignell2366]

I'd imagine there's been a few lost fingers on those tools without guards. I do'nt think i'd be too comfortable using one. Nice fix as usual

[@mikespain8655]

No way I would use that without a guard. Great job.

[@Z-Ack]

They tend to bite other parts on people over fingers. Typically legs and feet when they hang up and whip out your hands. With no blade brake on em they spin for too long after let off the trigger. Thats what makes em dangerous..

[@LoneStar1955]

I was raised on a farm and have seen a lot of nasty grease but I believe that one takes the cake. Worst I’ve seen in a long time. 😂

[@SamoMalo2]

When ever I need to swap a screw but I have a longer one available, I place sacrificial nut on it, cut the screw to length I need, use the nut to fix the threads.

[@jonnyduncan7056]

That wouldn't get a green "Passed", PAT test sticker by me!! Keep up the good work

[@tomgreen777]

Nice job! What is the bearing puller you’re using?

[@johnbullard5973]

These old tools are built to last, but the big motors do scare me. I have a similar vintage old Hitachi 9” circular saw, that scares the hell out of me. There’s no safety button , so starts when you pick it up by the handle / trigger, and the kick on start up !! But with a decent blade it makes short work off cutting through railway sleepers.

[@therabman_5606]

Nice to see life brought back into things, the throw away mindset annoys the life out of me

[@MichaelSattler-d2l]

Schöne alte Maschine 👍

[@tommyhanlon8012]

I've one of them old Makita's, Grand yoke, would cut a house in half, but you'd wanna keep a good hoult of it ! What brand is that little bearing puller can I ask ?

[@antman3525]

I can only hope that that unit is mounted on some mechanical contraption so that no one is near it when used. What's good is all it needed was a little yearly maintenance, not a major rebuild.

[@neilburton8131]

The old 9” grinder it’s like playing with a loaded gun no guard you know it’s going to take a finger but you’re not sure which one

[@rogermusgrove8991]

Ive got one similar it came with no name plate or lead how can you tell weather its 240 or 110v i think you channels brillient

[@zaxmaxlax]

Probably 230. If you have a 110 transformer you can test it first and see if it runs at the correct speed, if its slow its 230v, if you dont have a transformer it wouldnt matter if it was 110 anyways, may as well just test it directly on 230, if works, you got a free grinder.

[@rogermusgrove8991]

@@zaxmaxlax Thanks for the reply the only trouble is the armature not good

[@zaxmaxlax]

​@@rogermusgrove8991Well, its not worth fixing then. You can get no name brands 9in grinders for 50eur/quid or a new bosch/makita for about 150.

[@71crys]

Petit commentaire pour le référencement !!! le petit com qui fait plaisir.................

[@rogermusgrove8991]

Well done Dean i like the scew extraction

[@zaxmaxlax]

Dean, have you tested bosch gearbox grease for electric bikes? Its 10 euros a tube but they sell in bulk and its probably the same thing as gear grease for tools.

[@markmawson1]

Cleaning out the head of that grinder was like an archeological dig 😂, to get all that grease out into the bin just warm the housing up with the blow torch and it will melt the grease that's holding it to the housing and it should slide out well the majority of it anyway.

[@deandohertygreaser]

yes, but its more satifing to dig it out

[@ElMariachi1337]

I remember the days where I was putting armatures in the freezer 😅

[@luciensanchez6451]

The Death wheel lives to take another victim.

[@deandohertygreaser]

Dony worry the big kick they start with, normaly scares of any novice

[@ivanwinder2517]

Spoiler alert ‼️

[@kevinchamberlain7928]

Not grease! That is ear mung!

[@dannyharty3656]

That thing is a funking killer

[@dariovandemaele1956]

Ain't she a beauty of a machine, but make sure you hold that beast! Otherwise, she will get you.

[@alouisschafer7212]

The way this thing is build is on another level. But for christ sake I dont want to be around this boy on a site, lead almost ripped out of the tool wires hanging out of the handle and no guard on a 9 inch? Death wish that is.

[@neiltonks4627]

I wouldn’t use that, with no guard and the blade spinning inches from my fingers!

[@Alex-xj2kh]

9 inch with no guard is crazy

[@chrisjackson6605]

Recipe for finger amputation

[@chrisjackson6605]

​@@Alex-xj2khstatistics on 9inch grinder injuries are sufficiently adverse that parts of Australia ban their us on jobsites

[@Z-Ack]

You just gotta be careful and grip it tight. And make sure the disc is on tight and not cracked. And not to use the wrong size disc on it.. these tend to hurt people with or without a guard from people not gripping it tight the whole time and thinking it wont grab but they will and do. And aint very many men who can hold em when they do.. worked with a guy who used one without a deadmans switch and had a flip switch that i always told him is gonna screw him one day and one day i hear a bang and buncha noise and the thing is eating up the tile floor but shut itself off after it cut its own cord. Just like circular saws theyre a dangerous tool, u just gotta respect em and know their power..

[@leonclose7823]

I'd wager the disc guard hasn't been seen in many years.

[@Bugsyerin5646]

Go look at a company Engineer they have tools for removing screws and bolts very good.

[@RichardGarcia-fz8be]

Weres the guard

[@brendanwright5621]

My pet hate is when people take the guards off grinders. Unnecessary, if you can't use it with the guard on then wrong tool for the job, don't use it.

[@nelchan2421]

I'm, sleepy Dean. i'm going to 🛌 after this video.

[@RaulRuiz-n7z]

😅

[@irishrebel1976]

Ooof, no guard on a massive grinder with no brake.

[@jazko]

You can rejuvenize old grease with a little bit of motor oil and stir it real good.

[@Z-Ack]

Why wouldnt you just sand down the armature end to slide it in that bearing rather than heat the bearing with plastic guides and shields?? Just a wee bit of sanding to get the rust and crap off and wouldnt make it loose but just enough for it.. and the gear has a key so its not gonna spin off for any reason. I just dont see heating it like that doing any more good than harm it would do to the fresh bearing.

[@georg7405]

What kind of a coward still has the handle attached? Real men have 5 fingers on the bottom and the 3 remaining holding on to the head

[@rephleX67]

True warriors just duct tape the grinder to their foreheads and go in hands-free!

[@Dustin_the_wind]

And heaven help you if you ever hear it turn on.
