Just got one of these. Some fantastic 60s engineering on this bike. Twin lead shoes on a rear brake! never seen that before. 4 bearing crank and even the cam has roller bearings. Grease nipples on the swing arm. Not surprising these are still going 60 years later
Thanks for a very instructive video. I've used it continously on my 305 Dream cluch overhaul beside my Honda 305 Engine Repair Guide for 1961-67 C/CA72/77 (250-305) Dream. Thank you very much!! - Sverre
Centrifugal oil filter, not pump. Debris is thrown outwards & gets stuck. They need cleaning out as a service item hence the removable cover. Pump sits in the lower crankcase, the sump bung is actually bolted into the base plate of the pump.
Interesting, I'd never seen the primary drive side of a CB72/77 before although handled many a set of clutch plates for them in my early trade days. A tip on cover gaskets is grease both sides, help the gasket sit on the inner face and means you can often reuse them. I think the one on my CB250RS is on its third use maybe fourth. That model wasn't sold in the US but basically an XL250 engine in a road frame.
It should be noted that some very knowledgable mechanics say NOT to put the retaining wires back in because they can break and foul the oil strainer with metal bits. I'll likely remove mine the next time I'm into the clutch.
That information is A OLD MYTH! The truth is that HONDA NEVER DELETED THEM. In the early stages of these bikes it was found the 1st plate would over heat (wrong design of all disc and steel plates) which made it WARP BACK and loose contact withe the friction. HONDA doubled the thickness of that 1st steel. This COVERED THE groove for the wire in the "CLUTCH CENTER" so NO wires could be installed. HONDA redesigned the "CLUTCH CENTER" to allow the wires to be installed in ALL FOLLOWING CLUTCHES". The clutch he is showing was designed by HONDA and issued around 1966. It is called the "CUSH DRIVE CLUTCH. ..............lm

I agree! I wish I still had mine, but needed to trim down my projects. I'll have another someday!

Thank you for making these videos. They are a great help.
the pipes look like CL72/77 "TT" pipes because of the angle, a Rockey Cycle, Hap Jones product and also Webco.
You should tighten in a "star" rotation, just like any other multi screw plate.
joel huebner you’re right!

Te clutch baskes inner and outer should be deburred, also the steel inner plates fingers deburred too.
That’s not the oil pump the oil pump is on the bottom of the crank case, that is the oil filter
where did you buy the clutch kit ?
I saw a set of clutch pads for $40 on eBay but wasn't sure if it was gonna be correct
+Aric Parker I got them from a forum member named "LoudMouse" on here: www.honda305.com/forum/
Hey. Just curious. Were there any issues after the install? Great video. Thanks for making it!
65Superhawk no issues, just a stiff clutch due to the heavy duty springs.
That is an easy fix if you went back to stock springs. Thanks for replying. About to start my CB77 restoration this summer.....
I think that’s a ratchet in your hand. You don’t have to go 360°
