Topic: Swapping out fork seals w/o removing forks?

[ev0lution7]

My bike is a 67 750k but I think the forks are newer because the front had been wrecked or in a ditch at one time and now has some k8 parts on it.

they made cb750's in 67???

i am still shocked that we are even suggesting that you leave the fork tubes in the bike that is the lamest idea i have ever heard that like saying i'm going though all the trouble to get a new rear tire but i'm gunna reuse my 30+ yearold tube tubes are cheap REPLACE IT! its your life you are talking about this is not a car with 4 wheels and metal all around you this is a BIKE it was 2 wheel its dangerious!!!! anything on my bike that deals with brakes suspension, or tires i spare NO expensense!!!!! look at the post b4 mine... the guy rebuilt his forks and said the bike was AWSOME afterwards you want to take everything apart check it over good and put it back together i took my forks off and cleaned them and changed the fluid.. it made a world of difference now i realize that my springs are sagging so i bought some progressive springs from DYNOMAN.NET...  NUF SAID

Umm...some of us have owned our bikes for enough decades that we know what is in our forks.. we actually know our bikes and changing a seal and oil is like.. well changing the oil and seal.

 You are forgetting that you can wear out a set of seals in a season or two.

 Like I mentioned earlier, its easy on a 73 & later, but on a 72 or earlier, you pretty well need seal installing blocks or, you can damage the seals.

 Do you flush your motor eveytime you change the oil?

 One you get past your PO problems its finally your bike, & dont forget.. some on here, actually got theirs new..

 Its not How you get it done.. its THAT you get it done..

Oops, I got a little dislexic evOlution7 
Thanks for the link too, this will help anyone else that sniffs this one out.

754 I never blew a seal and never will, beastieality is not for me, my cousin on the other hand...

754 that is some great points and not very nice on the next to last one, I wish I had mine from the start 

Oh the PO's the PO's when will I get over the PO's... Might have to go to the doc and get a injection or lotion.

Also I wasn't worried about cleaning the forks at first, my bike was a storage unit find and spent most of its life so far on the center stand
I will clean everything out though and this will show others that had the same thought as I did to go ahead and do it while your in there.

Hi Goon,

You're already ahead of the game....... I can tell you've got a good attitude....... willing to change and adopt for the better of you and your bike....... that's important....... I've noticed some here that are severely lacking in that attitude department and diplomacy....

Ride On.....

Yeah I have the firm belief that anything is possible, after all Mary had a little lamb.

We reinvent the wheel on a weekly basis at my work so my self confidence is riding on that for everything else I do.

Holy crap, that walk thru for the forks is pure gold evOlution7!
 

It literally takes ALL the guess work out, and he even has a sweet pvc pipe connector that is the perfece for driving inthe new seal with. Oooh I have to go back and print this out for my Goon's home made honda manual

Hey for all that care. I pulled the snap ring and just lightly bounced the fork on a piece of wood and the seal came loose very easy! I couldn't imagine doing that with the forks/wheel on the bike!

[ev0lution7]

the reason i say just take them out is not because the P.O. might of damaged it but because its always a good idea to check out the front end everythime it needs service like i said i dont skimp its your life your talking about.... would you wear leathers and boots and a good helmet and put your "hot" Girl Friend on the back of your bike in a tank top short shorts.. and flip flops? oh and dont forget the $300 helmet on her head... if you go down her head will be ok but she will prol need alot of skin graphs!

come on guys its just not smart to leave important parts that might need inspection on the bike and not take them apart! if i need a new rear tire you bet i'm looking at my wheel bearings rear shocks.. swing arm pivot, rear brakes, front and rear sprockets, and chain....

my point is your only saving yourself a few min when you could save yourself a trip to the hospital if something goes wrong right???

I for one wil not do a full teardown, if I know what shape things are in, and its just time to change seals.

 My forks dont rust & I dont always use headlight ears.. & having owned both, I really prefer the 73 and later style on the 750..

[fuzzybutt]

sorry to hijack, just a question. i feel like an ass for not knowing this as i've been working on bikes, cars, boats for almost 30 years now. how important is it for the fork seal to get all the way to the bottom of the hole? the snap ring goes in well before the seal hits the bottom.

[jaknight]

You're OK Fuzzy,

As long as the snap ring does go in and seat in its grove........ you've got it made.

I have seen quite a few of the seal bottoming depths vary.  With the snap ring located and seated..... you're home free.

Yeah most can feel something different, I can tell really quick on all my vehicles when something is a miss, if I had my bike on  a main road for more than 5 mins and not just my side street I would feel the forks and how they need some juice.

This is not the case for all though, some need to look into there and see mainly if the bike is a mystery with the P.O's and all that fun.
