Fitted 100's of these and never broke one to date. I think people damage these because they do not tighten the bolts up evenly  :o

You need all covers off and the oil pump removed. Are you missing the bolt under the starter motor cover ? Once all bolts are out and the engine up side down, give the output shaft a tap with a plastic hammer  ;)

Hi all,
Anyone interested in a pair of White CB750 tank badges.
These are originals from Silvers £90 a pair.
Only been on for a year.
Sensible offers
Going to put them on eBay but will take them off for a member.
No Trigger before you ask  ;)

£90 ? They are now second hand and NOT in the Honda packaging. They must be worth 99p  ;)

Yes they are the groves but, i think that i maybe  wrong about the groves >>> https://www.cmsnl.com/honda-cb500k2-four-1973-usa_model461/countershaft-trns_23220323000/#.X8KWhOlxepg

I only have 500 gearboxes in the workshop at the moment. I will have to go to the stores to find a 550 so, i can compare  :o

Is the shaft the same as the 550 ?

Nope, 550 is 374 and the 500 is 323  ;)

Trigger can I ask if I find a good condition second hand one how would I tell the difference between a 500 and 550 as the images in the parts manuals look the same. I know I can't trust the manual so advice appreciated


The 550 (374) has 3 groves in the shaft and the 500 (323) has 2 groves in the shaft. That is the easy way to visually identify them   ;)

Always worth stripping a gear box down as, you never know what you will find  :o Looks like oil starvation but, not much heat. Expensive to find a good replacement  ::)

You CAN NOT use that type as, it does not have a running surface. you need the type like the Honda ones that have flat one side and a bevel sided  ;)
What happened to the ones you took off ?

Had a little time today so, split this gear box so, you can see how it split as you can't go off a manual  ;)

The circlips must be wround the correct way as, there is a flat side. The washer with the tags fits inside the washer once that washer is turned and acts as a lock.

Trigger, are there any easy ways of telling the difference between k6 and k7 heads?

Bigger valves on the later head.

If you have water in the bottom end, then you have a rust problem and rust & corrosion is not your friend when assessing a engine for rebuild.
If you wish to lock the engine up, you can place a bar through all the conrods small ends.

It depends on if, they are damaged or over tightened. I always fit new ones as, it is a mess if they start leaking  ;)
