welcome back to the shop guys today we'll be working on the RM250 back
here that's scattered in a million pieces but
what I have going on now is some parts cleaning so the engine is completely
apart back on that cart going to clean things up
shine all the parts up let's jump into it so I'll be cleaning all these parts
up here in the parts washer this is just a cheap Harbor Freight tank I added a
heater to it and some other stuff to turn it into a little monster but it is
well used you could say well crusty and rusty but it does work really well so
I'm gonna soak all these parts for about an hour and then get scrub in and I've
also got a little trick to show you guys how to speed up this process even
further let's go start dropping things down into the bottom now there's a
couple things I want to tie up before I drop them into the bottom I'm gonna put
zip ties on either end of the transmission shafts
as well as the kickstart shaft just to keep everything together and then for
things like the stator I'm not gonna soak these I'm just gonna brush them up
top now before I drop the cases and clutch cover into the cleaning tank I
like to pop out the old seals and always make note like take a picture or a video
like this of the seal depth like where it's sitting in the crank case before
you pull it out same goes on this side too and then pull out the filler plug
just to clean all inside of there - and for the bearings I'm gonna leave those
until afterwards especially the main bearings I like to pop the cases in the
oven that way the bearings just drop out basically doesn't damage the crank case
and another thing - I like to pull out the dowel pins as well as cylinder studs
now some of these dowel pins can be pretty crusty like really stuck in there
so I'll show you how I about pulling those out you can see this
one's already pretty messed up from me trying to get it out so what I'm gonna
do is squeeze it kind of mush it it also helps to add some heat to the equation
to find the bolt that fits in there and then give it a whack and there we go
she's out of there as you can see just scrubbing at it here and the tank is
working pretty good eating up all that dirt gaskets are just melting right off
- but there's something else I want to show you guys that's pretty cool so over
here we have a pressure washer inside of a cabinet some of you guys might
remember this thing rips pretty good drop the part inside close the door got
a foot pedal down here there is a little wand or whip hose inside and you just
get to work it takes very little manual labor to get this thing cleaned up
now the crankcase is free of any grime and oil and all we're left with is just
some corrosion and pitting from over the years we're gonna take care of that
later on but for right now I am going to finish off the rest of these parts
let's take a little halftime break from cleaning parts I got something cool to
show you guys here on a little side note I have been working on reorganizing the
warehouse a little bit got some new shelving in here just kind of redid
things but I did get some new shirts in I've got a short sleeve and a long
sleeve but something happened with them let me pull them out of the bag and show
you guys so I've been working on these shirts over the last couple months just
making 100% sure they are the absolute comfiest and best fitting shirts you
guys will ever wear I know I love them where I'm all day long so I got my order
in thousands of dollars with the t-shirts and unfortunately due to some
miscommunication the neck tags were sewn in at the wrong spot they're supposed to
be down here super pissed about it and I don't really feel comfortable putting
these shirts up on the website and selling them there's nothing wrong with
the shirts besides the neck tag I just don't really like it not spot wasn't
what I had requested what I've decided to do is give these shirts away now for
the next week if you order more than $25 worth of stuff on Prime I'll include a
t-shirt for free all you have to do is put your t-shirt size in the order notes
so you guys have until December or actually January 15th to get a free
t-shirt and I have shirt sizes extra small through 2xl so nothing outside of
that now just to clarify when you're checking out on prime you'll need to put
your t-shirt size right here in the special instructions for seller box now
I'll want to get the cylinder and crank cleaned up before I send them out for
repair and for the cylinder the exhaust valve needs to be removed which I've
already done as well as these studs so we'll pull those out right now
alright the cylinders all cleaned up looking good and ready to send out for
repair so I'll be sending this out to power steel USA to fix this detonation
damage right here so basically what they're gonna do is TIG weld that strip
all the nickel plating off replate it obviously smooth everything
out fix this issue right here near the exhaust port also one more thing once
you're done cleaning all the carbon off your cylinder you want to check the
exhaust bridge and actually this one has two of them it's very common for those
things to crack you know take a good look at those make sure they're not
damaged if they are power steel can weld those up and get those back in order and
whenever you send out a cylinder for repair or like a replate you want to
include the piston with it obviously we're going to the new piston here this
is a pro-x standard size so we're gonna send that piston with the cylinder to
have it perfectly match to the bore and when we get this thing back we will be
all ready to rock I'm a big fan of the pro-x stuff these parts are made in
Japan so the same quality or if not better than the OEM parts and in many
cases some of the OEMs actually use Pro X so the really good stuff I snagged
this piston from Rocky Mountain now how did I go about getting all of the carbon
build up out of the exhaust valve areas that stuff is pretty stubborn but what
did I end up doing was soaking the cylinder in simple green degreaser that
ate up most of it that degreaser is pretty safe on the aluminum and then for
the last little bits of it I used equal one mag wheel cleaner and I cleaned it
up pretty well but once again if you guys have access to a vapor blaster that
work a lot quicker as for the crank I will be rebuilding this one it is the
stock crank so they're really solid I ordered up a pro-x rod kit for it so
that comes with the rod bearings everything needed to rebuild it so as
soon as I get that rod I'll be sending the crank and rod out to you crank works
in Arizona we're gonna go through rebuild it true it up and I will have a
fresh crank or ready to go now something you can do to brighten up the aluminum
and get rid of some of this corrosion is to use an etching cleaner and her clutch
cover has some dirt staining on it so this cleaner will get rid of most of
that so what we have here is a bucket full of Eagle one mag wheel cleaner it's
pretty similar to this stuff right here just a little bit different we're just
gonna drop these parts right into there and let them soak for a few minutes when
it's all done soaking give a little scrub to help that cleaner deal with job
and there we go not a huge difference but definitely brightens it up a little
bit now with the clutch cover I only soaked half of the part you can see the
difference right here clean this side and didn't clean that side there so nice
little difference there now after a bit of scrubbing we've got every single
thing cleaned up and dried off looking pretty good obviously we still need a
shine at the cases clean up the corrosion on the covers and all that but
immediately after you wash the parts off you want to draw him off with an air
compressor so things like the transmission and gearshift components
anything bare steel will start to develop rust right away now how I went
about cleaning up the hardware is I draw each lot into this little wire basket
let it soak in the parts washer and then brought it over to the pressure wash
cabinet and blew it off and they came out pretty clean I've got everything
labeled and organized just going through and inspecting things making sure I
don't need to replace any of this obviously most of the bolts I will be
either replating or replacing all together always good to just check out
everything individually make sure you don't have stripped heads like this one
he just notice that we'll have to replace
it also pull the part a few more things like the Kickstarter the gears on here
kind of shredded up good thing I pulled it apart I'll need to replace these you
can see that top so those gears are starting to wear away Oh time to replace
it now with everything completely broken down and cleaned up this is where I
really get detailed and check out every single little component make sure I have
all my bases covered I'd hate to begin assembly and forget like a little screw
or washer and hold up the whole process now as far as the exhaust valve parts
you can see these things cleaned up really well I did do a separate video on
this because getting all that carbon off can be quite the pain in the butt so
yeah I did do a separate video but basically what I did is oil them on the
stove over here and then do some scrubbing on them and then finish them
off over here on the bench grinder with the cleaning wheels you can see they
turned out really well so keep an eye out for that video now I
know some of you guys are gonna be curious about this parts washer since it
does work really well so basically it is from Harbor Freight 20 gallon tank I
added a heater to it now the heat really makes the biggest difference and
cleaning the parts you can drop everything in the bottom and it really
just eats up that dirt and grime I also added a drain on this side that's a huge
plus I also added a few more features that are pretty nice now if you guys
want more info on how to build one of these tanks it's pretty straightforward
and super cheap to do I will link a video course that I built a while back
down below now the degreaser I'm using in the tank is the simple green from
Home Depot I mix it at a 50/50 ratio with water got to be really careful with
the degreaser you use it in the tank because some degreasers when you heat it
up it'll actually turn aluminum plaque and this stuff I found is very safe to
use with aluminum bars the temperature of the tank you can go from 100 degrees
all the way up to boiling now I keep it around 120 130 that seems to be the
sweet spot if you really have something nasty you can turn it up but you don't
want to have it to the point where it's literally steaming you don't want to be
breathing that stuff Finn and I'm sure you guys want to know
about the pressure wash cabinet so basically it is from Harbor Freight as
well I should just get a Harbor Freight sponsorship at this point but it has a
electric pressure washer hooked up to it got the foot pedal got the hose that
comes up and inside got the whip pose in there it has a light pretty sweet very
basic setup I mean I could add more features to it like wiper that would be
really handy yeah pretty straightforward I don't have any
videos on how I built this thing I am considering doing a course on it as well
not sure about it yet there are still some more refinements I would like to
make to the cabinet but that is the basic gist of the pressure-wash cabinet
now to give you guys a little preview of what's to come with a channel I already
cleaned up the clutch cover got our look at prime thing is absolutely beautiful
and I'll be doing the same thing to the crank cases as well so hang in there
lots of good stuff on the way now one more thing before I go this whole bike
