Thanks! Please to hear that you are enjoying videos.

Thank's for the positive feedback regarding the video. I'm pleased you're enjoying using the tools and finding them easy to use.

$50 bucks + tax and shipping ?? too high.

Yes, the seals are quite tricky to install without a suitable tool due to the large size and it can be quite easy to damage them just if not careful. A suitable tool makes it so much easier.

@@TokyoOffroad where did you get this tool? where can i buy it? :-)

I’m 2 years to late mate, but a socket will do the trick

@@jiegodfrey Thanks mate.. got it done as you recommended

Thanks for your order! It's good to be prepared :-)

Dan Grad - They’re called Steg Pegz

The Duke - If the seal skirt is bent and distorted I recommend buying a new seal and try the install again. If the case seal seating area is scratched you can apply some thread lock to the seal skirt before install as I mentioned in the video. Installing the new seal straight using a socket and hammer is not easy which is why I developed the press tool. If you’d like to purchase one they are available on the Tokyo Offroad Webshop and happy to ship worldwide. If you’re going to use a a socket and hammer then I suggest you go very carefully and check the seal alignment after every tap.

never mind just saw you put it in! sorry

Oli M - Yes, the o-ring was installed...

@@TokyoOffroad yes sorry should have finished watching before commenting. Also Mark any chance you can make a video of replacing the KTM fuel pump filter? Thanks in advance your videos are so helpful

No, sorry but the seal size is different from the wheel bearing size, plus the countershaft press tool needs to be able to fit over the countershaft.

@@TokyoOffroad dang. : (

An over-tight chain will shorten the life of the seal. Yes, pressure washer pointed directly at seals is not good and will possibly force dirt into the seal.

I do sell the countershaft oil seal tool shown in the video on the Tokyo Offroad webshop, if you'd like to buy one: www.tokyooffroad.com/product/countershaft-seal-press-tool-cspt/ The other option is to hammer in the seal using an appropriately sized socket, but it's very easy to get the seal canted. If this happens stop immediately and try to correct it, or you will ruin the seal.

really like the drive tool you,ve made, had exactly the problem you described, canting the seal tapping it in with a socket, and ended up worsening the housing scratches, someone else had also had the same problem previously on my 530.

I use Honda Moly 60. Unfortunately it’s no longer available

I'm not familiar with the 790 Adventure. Typically countershaft seal leaks are either due to the seal wearing out after high hours in difficult conditions, the chain tension being too tight, or the countershaft sprocket being loose and not apply sufficient pressure to the internal o-ring to compress it and make a seal. As shown in the video it's pretty easy to fix and the required parts are relatively inexpensive. Note that the press tool shown in the video will only work on off-road models (EXC, EXC-F, XC, XC-W). The 690, 790 and 890 have a different countershaft design (nut is used to secure the sprocket instead of a bolt).

@@TokyoOffroad damn… yeah… an odd thing to have issues on so many models.. but after I showed interest on auction. They sent me a quote for shipping and added in.. ohh the bike has an oil leak that’s well known! 🤦🏻‍♂️ guess if I buy I need to fab or make a tool. I do have bearing installation tools.. see what others are doing..

Yes. The stock position is in front of the right radiator, but is prone to damage

The install difficulty is not getting the seal flush, rather due to the size of the seal it's easy to get it canted while driving it in and then ruin the seal. I've seen quite a few KZfaq videos of people running in to exactly this problem. Using the Tokyo Offroad press tool minimizes the chance of any install issues and makes it much easier.

Excellent, thank you!

It was a small stone. You can see it on top of the chain before the sprocket is removed.

@@TokyoOffroad Dam strait! I can see it! I just hate it when stuff flies off when I'm working on stuff! Great stuff you do! Thanks!

or buy a seal puller for $10 lol

I used some medium strength blue Loctite 243 for this. I didn't want to use high strength as it would make future replacements more difficult (require heat to remove the seal). As mentioned in the video this is optional. If there are any scratches it's definitely a good idea...

@@TokyoOffroad Yes, red is too much. What I'm saying is that there is a locktight product (green) that works well for this sort of work, bearing journal fit, etc. It is very thin, and wicks into scratches like you mentioned might be in the case. Heat is not needed, despite locktights description saying it is medium to high strength. I use it all the time to help with bearing fit in bores that may be less than stellar, or where I want to be sure the inner or outer race stays put on the shaft or bore.

Mike McKay - Yes, the horn has been relocated from the stock position in front of the right radiator.

Pretty smart, I am going to do that. Thank you!

jarel nomeh - That’s the first Ive heard of that. Please can you quote a source of your information.

@@TokyoOffroad Slavens Racing has mentioned that in one of his videos. He's local.

Could you quote what Jeff Slavens said about Loctite as I haven’t heard of this before. I did try Googling but couldn’t find anything. Note that I have no connection with Loctite and all of their products which I use I purchase at retail cost. I do not actively advertise Loctite products, simply share information regarding what product I use on my bikes.

@@TokyoOffroad kzfaq.info/get/bejne/icyejduFrMi4qI0.html

Thanks for the link to the video. In it Jeff Slavens says "The dick who owns Loctite has been trying to shut down trails in SW Colorado". I'm wondering specifically who Jeff referring to. The owner of Loctite is Henkel AG (Loctite was acquired in 1997), but I'm guessing he doesn't mean Henkel. Currently the key Henkel Loctite executives listed are Robert Aller (CFO) and Louis Baccei President of R&D. BOD members are listed here: www.bloomberg.com/research/stocks/private/people.asp?privcapId=285877 . So who is it that Jeff is referring to and were they using their own money, or corporate Henkel Loctite money to do the campaigning?

No, because I did put a new o-ring in...

He’s usually very meticulous… I was surprised he didn’t.

Thanks for your interest. Yes, the tool is available for sale on the Tokyo Offroad webshop here: www.tokyooffroad.com/product/countershaft-seal-press-tool-cspt/

LOL

I’m guessing they know a better way, but don’t want to share the details ;-)

da - The use of Loctite to retain seals of this type and bearings is common and not something I invented. The advantages of using Loctite include 1) It will hold the seal in place better and 2) If there is any minor damage to the case (scratches caused during seal removal) it will provide a better seal. Only a small amount of Loctite is required and you must be careful not to get any on the rubber part of the seal, as mentioned in the video. If Loctite 243 (medium) seal removal and bore cleaning will still straightforward. But it’s totally optional as I noted in the video.

Ya its really common to use low strength loctite to seal/glue metal seals in place. That being said using it on a rubber seal accomplishes nothing lol.

People should really try to be a better mechanic before posting comments. Your use of loctite, and description of why to use it is spot on on this video.
