Aussie Cafe - Project Name Unknown...
« on: August 23, 2009, 12:49:56 AM »
Well, I've been on here for some time now, reading and enjoying everyone's builds.
Time to begin mine.

...Background...
I live in Melbourne and purchased a CB750 K3 from Adelaide.
The pickup envolved 3 good mates, a borrowed trailer, company vehicle (free fuel) and a 7000km return trip. (Corrected it was 2000km, typo)
We stopped twice on the way for fuel before crossing the border, had McDonalds in Adelaide then returned home rotating drivers along the way.


This is what I had ended up with, complete with a few boxes of spares.




The bike would kick over, but not start.
Clean fuel, oil and a bit of bike starter and it "rattled" to life.



I've slowly been making progress, breaking the engine down.
Have now stripped the engine to nothing but baged (and labelled) parts.



Found that the crankcase was a little worse for wear, and the general consensus on the forum was it should be replaced.
http://forums.sohc4.net/index.php?topic=47353.msg564229#msg564229



After breaking a cylinder stud in replacement cases and attemping various method of removal it was finally removed through Spark Erosion.
http://forums.sohc4.net/index.php?topic=55987.msg603300#msg603300



Stripped the replacement cases of paint and sprayed the bottom half today with Duplicolor Engine Paint.
Turned out pretty well, I plan on hitting it with the heatgun as my oven is not large enough to fit the case.







I've rebuilt the Master Cylinder and have polished it to a mirror like finish.


The completed "shopping list" has already been posted and can be found here:
http://forums.sohc4.net/index.php?topic=56469.msg608922#msg608922



Finally, after careful consideration I can not fault Capy's color scheme, so I'm aiming to end up with a bike that runs well.
Handles well and looks a treat!



This is the first time I have ever attempted an engine rebuild and hope to learn as I go, seeking the expertise from everyone here. ;D ;D ;D

A big thumbs up to everyone who have already helped me along the way...
Cheers

I don't know if it will help or not but you can make a really simple oven by using some sisal insulation to make a small oven and putting a bar heater in it. I have used a small table and hung sisal off it and lined the underside, with the small bar heater inside it heats up pretty quick.

Thanks for the tip, I might have to use it yet.
A bit of chipboard and the insulation should do the trick if I find I cant fit things in...



I had unscrew 4 screws and remove the inside pane of glass, the oven depth is 46cm with this removed.
I then very cautiously raised the temperate to 120 deg Celsius so as not to fracture the front pane, made the assumption its not heat treated like the inside pane.

Its in the oven as I type this, another 30 minutes and I'll remove it.

What's a 750 worth on your side of the Tasman mate?

I paid $3.2k for it...
In hindsight it was probably a bit on the expensive side, but the spares that came with it I see added a little value.

They hard to come by in NZ?

Had a mother of a time trying to the "Kick Starter Shaft Stopper Pin" until I found this.

http://forums.sohc4.net/index.php?topic=36875.msg380587#msg380587

Worked a charm!  Even after I had mangled the top of the pin with vice grips.

About to clean up the gears from my old engine so they can be tested at my local NDT shop for possible cracks etc.

Good Lord!!!! :o
A 7000km round trip from Melbourne to Adelaide? Good thing you had the company car then!   ;) ;D

The case is looking nice. Even just an enclosure in your workspace made of heavy plastic sheet  and gaffer tape with a space/bar heater in it will warm up quick and do the job. Works great as a makeshift spray-booth/oven as well!
Just make sure you don't leave the bar heater exposed while you spray!
It's also a lot healthier to do than bung it in the oven you use to cook your meals! Save's a lot of grief from the other half as well! there's some nasty chemical combinations that can hang around for a long time doing it  like that! The kind of stuff that puts hairs on your third testicle, if you get my drift. (i have worked as an industrial/commercial painter for 15 years, and believe me, i wish i had listened to the advice i got much earlier than i did. My health is suffering as a result!)
Look forward to seeing more updates!
cheers

I think that should read "2000 km" round trip, which is still a bloody long way.... ;)

I'm looking forward to this build mate.  Looks like you're very methodical and have the bank to back it up.  I love Carpy's "Vincent" also. 

Don't forget to add the pedestrian slicer to your shopping list.   ;D

Apologies for lack of updates, not much has happened over the past few weeks.

I've been waiting for Honda Bearings to come in from O/S, the 3 week wait can be a bummer...

Also waiting on my Cycle X lightened and balanced crankshaft to arrive, it "should" be here next week after a few delays in its shipping.

Mick7504 posted some great info that would have saved me some time, worth checking out if your looking to replace all bearings like I am.
http://forums.sohc4.net/index.php?topic=60026.0


I'm currently rebuilding the transmission, and have a little play with one part that I am a little concerned about...
I'd appreciate some advice.

Tonight I am in the process of fitting the new bearings to the transmission.
Only trouble is I am not sure how.

Have started a topic here, I'm sure its a stupid question with a simple answer but I'd rather not damage the new bearings...

Also spoke with a sand blaster today about getting the frame done.  Gave a rough estimate of $110 AUD, is that reasonable?

Wow, that "shopping list" pic from the first post is kind of amazing.  It looks like the big fireworks displays my parents would never let me get (might be an American thing).  Now you just need a giant gift basket and it'll be the best present ever.

Great work, keep it up.

Thanks MacM,
Its taken me the better part of 9 months to get it all together.

Still need to place my order with Carpy, waiting on a few extra '000s to be added to the end of my current bank balance first...

Well with the support of w1sa, Bodi, Mick7504 & bucky katt I managed to get the bearings onto the appropriate shafts...

Transmission, Primary Drive & Final Drive

The sprocket however for my final drive looks damaged.
Is this normal or should I replace it?

I've installed the Kick Start spindle and gear.
It spins freely when not engaged and has a fair amount of play...

Is it meant to be this way or am I missing something?


Note: The first of my videos, thanks Youtube!
