- Pulled the engine to check out some broken gear teeth. Found the kickstart gear chewed up. Also found some corrosion on the crankshaft.

Dino - No gaskets on the case. Honda uses a similar product to seal the two halves. So far no leaks...fingers crossed. Thanks for the comment!
Loads too much gasket sealant! An equal amount of it will be pushed out into the engine ! A little smear on the end of your finger is ample ! Regards
just wanted to write the same, WAY too much sealant
Can get in and block the small oil galleries stopping oil flow.
Was I not seeing it or was your clutch shaft set ring missing from around the bearing (basket side.) If you had clutch slipping problems might of been the reason why.
Interesting about the kick start teeth, I've seen a few like that myself but never found out how it happens. Honda now use a sealer like you have there on most of their engine cases and horizontally split cases only ever use sealant as did some rocker box covers.
keepitrunning - That loctite sealant is great stuff and we're still leak free. The gear is a bit of a mystery, but it's probably a case of someone engaging the kick start lever while the engine is running. How ever it happened, it must have made a terrible noise. Thanks!
In The Shop Good show, I'll bear that loctite in mind although I still have some Honda-bond myself so it might be a while before i need to look for something else. It's possible I might soon be moving on, job wise ( not going back to my old job that is) to a job involved more with the older Honda's so knowing it's possible to do that with that gear is very useful, I often accidentally catch my kick start on my CB250RS which makes a bit of clatter but so far, over thirty years or more, has not caused a problem. Perhaps they made the gears tougher in later bikes to avoid it, I seem to recall we sold a lot of gears for the 100/125/185 singles as well, may have been the same problem as I do recall a few of those being short a gear or two on the odd occasions I saw the old one.
Hi Keegan. I have a cb175 with a squeal on the starter. Not sure whether it's the starter clutch or starter motor. If I remove the starter motor to lubricate it and clean inside, is there a way of ensuring the clutch chain does not drop into the engine when I remove starter?
Thanks. Regards, Justin Isitt. Uk
Far to much sealant , for all the stuff that gets pushed out , the same amount goes in the way .
This will detach and block oilways and journals .
I use blue hylomar and it should be so thinly spread as should look translucent ,
and if you don't know what that means you shouldn't be working on engines until you have .
That was taught to me by an old school Honda mechanic .
Where did you get your engine stand? I've been looking for one
How long did you leave the vinegar soaking in the tank
congratulations.i have the same bike and i am in restoration process.The engine (i hope) was repaired in a mechanic.And now i am trying to put it alla together and fix it like new.
you giving me a lot of courage thank you.
Thanks for the nice comment! Good luck on your project.
Darryll - Congrats on the the new bike. You can send me an email if you want to talk about the bike. keegansgarage@gmail.com
Too much sealer🫣
i have a 1970 model...ive owned it for 23 years and i have done a top end rebuild. if your gonna restore the engine in one of these, do yourself a favour and hunt down factory Honda parts ( they fit right)...now onto my cb72
I am currently trying to remove the motor from this exact same bike. I am stuck. What tips can you offer? I was hoping there would be video
Darryl - We also have a 72 CL175 and we are trying remove unsuccessfully the lower crankcase. Looks like it's still factory sealed. Any suggestions?
I had one of these about 30 years ago. Really good series - looking forward to part 6
Thanks for the nice comment! Part 6 is coming soon...I hope. Thanks again.
Respected sir cb 175 k4 how much contingrod play ???.
Ive got a 71 cb175, replaced half the engine with an SL175
its a fun project, these bikes never die
I'm pretty sure I've got the same problem with my kick start, can I ask how long it took you to pull the motor and get it put back together?
I had one of these, blue, for my first vehicle in 1976 when I was 16. I had a love/hate relationship with it. I routinely boogered up the spark plug holes by putting spark plugs in when the engine was hot. If I ran the rpms high it would leak oil from then until I replaced the gasket. It had a small sprockets, so it could go fast- IF you had a tail wind, and weren't going uphill. It had lots of mechanical problems: didn't like to idle (rheostat, I guess), blinker quit, so I had to do that manually! Still, it gave me freedom to roam the roads!
ltcajh If they all ran perfectly, somehow I don't think we would love them as much. Thanks for the great comments!
Just brought the exact same bike and live in Minneapolis would love to talk
great info! im curious, are you not using gaskets?
Can't wait to see the finish product !
do you have to pull the motor to replace the kick-start gear?
Yeah, I believe so. You've got to get the bottom off and the only way to to that, as far as I can tell, is to pull the whole motor
I am doing mine this winter , thanks for the info. keith
Good Luck Keith! Thanks for the comment.
