some bottom end questions

[snoopjonnyjon]

Yeah, it's just a spreader to keep the crank from bending in on itself on the side opposite the crank pin.

[tschisi]

Did you also use some underlays for the cases?
hm, nevertheless using a puller tool is more sympathetic to me...

I havnt seen a puller that will work on the K5 crank.. (no threads on the primary side... only a c-clip)..



No press is needed..     

heat the bearing (I use a few sockets heated to 500F)...     freeze the crank...   (with crank Jig installed)...    and the two will FALL together from their own weight.

If you work fast/orginised enough... (have the tranny already assembled in the case)... you can have both mains heated... Case sealer already applied....  You can put all the bottom end together with one freezer session on the crank...

It has a c-clip?
I didn?t see one 
So i would need the adapter mentioned in reply #27?!

Heating/freezing:
Don?t i have to install the crank seals before assembling?
Aren?t they damaged when heating?

Didnt see the "adaptor".. Didnt follow this post till just now


Here is my order.... Not for the faint of heart, or the SLOW worker.. as it all happens VERY VERY fast..

Get a Beer...

I install crank seals, then mains in the cases Using Heat/freeze method (drink a beer)....   install tranny...  (dont forget to GREASE ALL SEALS)   

Oil crank.... put in freezer overnight... Have another beer or 4

Next day... turn oven on to 500F..   put in 4 impact sockets, that are same size as "inner race" on mains.. Have a beer.


let sockets heat for about an hour... or so.. have 2 beers

take 2 sockets out... Place on the inner race of each case.. for about 4min... This method keeps all heat away from crank seals (your next to the freezer, get another beer)

While those are on there... Put Case sealer on Primary side case..

Get other 2 sockets... Place on mains (take other 2 off).. (need another beer?)

let sit for 2 min... then go get the crank (my freezer is a 1min round trip from bench).. (no time for beer need to work fast at this point.)


Drop crank in Clutch side case (the one the tranny is in)... it will fall all the way through and go "CLUNK" against the main...  (have to have case proped up so crank end wont hit bench).. I have a universal motor stand built out of 2x4's for this...

Imediatly get ignition side case.. and Drop on...

Make quick sure it spins free and is centered..   now is the quick time for a light tap with a rubber hammer to undo any bind your in...

Install Case bolts you ALREADY HAVE LAYED OUT.. In order... along with proper tools.....

Torque to half spec...
...........Have a sip of beer................   
Torque to full spec...

Have a beer.. you did good..

You would need the "c-clip" adaptor ... to work on a Kx crank..


Yes. there is a C-clip... that holds the gear onto the end of the crank on the primary side...

[tschisi]

I?ll (have to) go the middle way, because i can only order the no-name tool shown above.

So i will freeze/heat the crank into the right case without a tool.
Just like in beer-loving motorrad?s guidance.

Then use the tool to pull the crank into the left case half without time pressure.
With a little luck one of the two nuts from the tool-pic fits the k5?s crank-thread.

I?m doing this the first time so i?d like to avoid the tool-less method...

Thats the way I did mine.......the crank puller does not come with the required nuts, just use your existing flywheel nut with the tool.......no hammers needed!

hm, i thought the tool-nuts have threads on the inner and the outer side so they can be fixed on both the crank and in the tool?!

hi motorrad
 thanks for that info  that hot socket  is a good idea [i will probably need 10 sockets ] shame kawasaki dont leave us fit  the seasl from the outside like honda

anyone use locktite on main bearing journals and case housings ?

Yes read my jeff ward motor build thread about retaining compound...
And always use case sealer on the seals...


I plan on makeing a set of cases that I can change them from the outside.

Still waiting f?r the parts...

In between i heards that the HotRods products are not so good.
Would you confirm that?
I ordered a HotRods connecting rod set, no Kawasaki set available...

[kwakman]

buy a vesrah rod kit.theyre forged, made in japan and have silver plated bearing cages which are tougher and lighter. don't know about you, but I kinda need a beer after that.........

[crazyolbastard]

beers all around,
great advise

thanks a 12 pack motard
 

[tschisi]

btw,
I?ve got heat traces on both of my crank halfs:



I?m planning to get a new conrod-set and have one crank half repaired (it?s worn by 0,05mm on the bearing seat).
So, should i worry about those heat-traces additionally?

I think my bearing seats in the case are ok, because i see no damages, and the bearings can?t be inserted/removed without heating or tools?!
