Re: Cl175 dropped on a beach rebuild

I'm planning to dry fit everything and check before wasting gaskets

Re: Cl175 dropped on a beach rebuild

So I put the cases back together ( held with the 8 mm bolts only not the 6mm's and no cement yet) i tried to run thru all the gears 1-5 but can't , or at least there seems to be a neutral between 3rd and fourth and I couldn't get into fifth at all. As it stands the gear selector spindle is the only bit I haven't touched ( it moves freely ) I'm looking for some advice on this before I seal the cases. I opened and checked every thing about 10 times. I realize that spinning the imput spindle by hand isn't the same as redlining so... Will it move more easily at speed / obviously oil will help. Of am I needing to replace the ...... Drum?
The gears themselves look good , all have good teeth and no obvious wear or signs of slipage . Thanks in advance.

Re: Cl175 dropped on a beach rebuild

Thanks for the advice Steve. It was a burr in the gear drum labyrinth, tiny little thing only took about a week of headbanging to find and fix
So cases are now sealed

Re: Cl175 dropped on a beach rebuild

I'm glad you found and fixed it......
Amazing that such a small deviation from the pattern can cause such trouble shifting....
Worn guide pins on the shift forks will show the same symptoms as well....

Re: Cl175 dropped on a beach rebuild

So one of the BIG issues of putting cb2000 cranks into a cb175 is the differences in the splines on the primary gear and the offset gearing. The 175's have an off set geared push clutch, the cb200 has a single primary gear and a pull clutch and as the splines coming off the crank are different you can't just swap them out...... Luckily there are other OEM options. I spent about 6 months trawling through parts lists trying to figure this out

Re: Cl175 dropped on a beach rebuild

You can't just tease us like that and not let us know. How did you make it fit together?

Re: Cl175 dropped on a beach rebuild

So I started on the clutch cover and the clutch plates last night . The cover still had paint on it, not much but some , under th grit. Sanded back the clutch plates

Ok you all probably know this history
Cb175 ran from 1968- 1973
Cb 200 ran from 1973- 1974
So while the 175 and 200 share some parts ( front and rear hubs for example) there are others that have crucial differences the clutch being one of them. The Cb175 has a push clutch and the Cb200 has a pull clutch.( the clutch and friction plates are the same in both bikes)
the magic bikes which I've been stealing parts from are the lowly Cd 175 (or Ca 175 as they were marketed in the states.)
The Cd175 were made from 1967-1979 these bikes spanned the life of the two Cb's but the cases and covers are cb175 ( meaning a push clutch). At some point after 1973 the frugal people at Honda stopped using the offset primary gear from the cb175's. and started using the single geared system of the cb200 attached to the push style clutch basket that the Cd175's had been using since 1967
So I'm using a 1979 Cd175 A5 clutch basket ( this model might not have been sold in th US ? )
There are probably other parts that would work as well.... ?
Other than dremeling the cases to fit and the copper gaskets everything is stock OEM
The engine parts at the moment

1969 Cl175 K3 cases and gearing, head,valves
1974 Cb200 crank, pistons, barrels, and the longer studs, oil pump (it has a bigger plunger than the 175)
1979 Cd175 clutch, cam covers, two keihin pw22 carbs (24mm) these might be to big?
Carb advice would be appreciated

Re: Cl175 dropped on a beach rebuild

Just got a score Cl160 tank for $50 ($30US)
Im Definitely doing a Johnny Cash :lol:

Re: Cl175 dropped on a beach rebuild

I used a 1968 CL 175 tank (same shape, different mounts), but had to pein the underside within the tunnel for clearance......
You'll also have to modify the rear mounts on either the tank or the frame..... The great part is the result looks like it belongs there, and an additional few CB/CL 160 parts can really "vintage" out the look.....

Since I'll ultimately be using a modified "sloper" engine and CL type pipes to get mine as close as possible to the "Look" of a CL72/CL77, feel free to copy as much of the look as you like....I'll even provide an "other parts used" list if you want one......

 

[Simo]

Re: Cl175 dropped on a beach rebuild

Nice one I love the look
So there's a new trick to learn
I didn't think the tank would just bolt on
Did you heat the tunnel at all before hitting it with a hammer? Any other advice before I make a mess and bog it up?
Your advice is always appreciated
Regards

Re: Cl175 dropped on a beach rebuild

I eased the tank onto the frame and magic-markered where there was interference.... Then flipped it upside-down in my lap and gently tapped with a 16 oz ball pein hammer in that area..... Repeat until the tank can wobble in/on its mounts without touching the frame...Slow and gentle is much better than a good whomp, you are attempting to stretch the metal slightly with each strike/tap....I did mine cold...Took about an hour, and probably 20 trial fits/remarkings......

That is a pretty good collection of parts, thanks for sharing.

Re: Cl175 dropped on a beach rebuild

Yeah, but as your aware from my first photo it's all a case of one mans trash is another's treasure. There is an unending supply of people willing to pull stuff apart, put it a box , let it get a patina of rust, then sell it cheaply. Or so it seems. At the moment my largest capital outlay has been the cl175 at $100 nz and th cl160 tank for $50 everything else combined has cost less than than the tank... So current total about $120 US not a huge investment if she works :?
