Chain oiler discussion, Phantom or Real

[Ghost-Flame]

Here is what people are referring to as the chain oiler. Sorry for bringing this up.

But, someon easked and I want to know. read this thread http://honda-cb750-s.456789.n3.nabble.com/Got-a-slow-leak-td461760.html

Freerider, just to throw my 2 cents in. My 74 has a chain oiling system that was stock. The oil passes through the center of the counter shaft sprocket through an O-ring mechanism. Adjustment is explained in the Clymer manual for the SOHC 750s. It only requires a small amount, if someone cranked it open too much you will have oil all over the place. Best way is to clean the area then watch were the oil is coming from. The seals around the gear shifter are easy to replace, could be that. The O-ring at the chain oiler could be worn out also.


The oiler works from the center of the counter shaft. The shaft has an oil passage through its center. I don't know about all Honda 750s but my 74 has it. Adjustment is done by loosening a lock nut in the center of the counter shaft and either turning the oiler in for less flow or out for more. Then tighten the locking nut. If the adjustment is out too much the chain is not the only thing that will be well oiled :)
Some owners just close it and keep an eye on their chains. I have mine open just a little, but I also used lube on my chain.

                                O.K. "IF" this is in the CLYMER book(M341) 7th edition 1978
                  please what page I've been through this book and must of skipped that chapter.
      Thoughs "BONE HEADS" that didn't know the old Harleys thought the h.d.s leaked oil all the time
 WELL they were right but only when the bike was running and it was the chain oiler,would leack about the size of a silver dollar over night,saved a lot of chains.Would see leaking(drops) if left still ideling.
    there was adjustment screw,One on my 750 would be A plus ,

The old oil leaking was from engine breather tube aimed at drive chains to give a little continuous lubrication- this helped chains last longer but oily chains leave the excess wherever and whenever too much gets on chain. Parking lets the old design drop the excess from bottom of chain guard and primary. When AMF tried to cut down on oil drips they had a few broken chains, cracked tranny cases. Most of the later Japanese bikes vented the breather into aircleaner area and burned the fumes. Some of the early English bike riders ran vent tubes down to chain area and got the longer chain life and drips like early Harleys. Early Honda Dreams had enclosed chain cases to keep cleaner.

Ghost,the oiler you mention that feeds thru the output is the same thing that I read about in the FSM.According to the FSM my bike has it,but I cant see it. I know Tools says he has never seen one and he has been intimate with several of these engines,so I really tend to take his word on that. It is just so strange that honda says it's there when it's not.At least on my bike anyways

[TOOLS1]

I have never seen a drive chain oiler on any bike that used the engines oil. Think about the liability if it failed, and dumped the oil out, or some one did not check the oil. I think Honda is too smart to set themselves up, for replacing thousands of engines, or injury's from engines locking up at speed. Chains are cheap! Engine are expensive!!!!!!
Also I have never seen anything in print put out by Honda that states there is a drive chain oiler. I think people are referring to the fact that the primary chain is inside the crankcase, and running in oil. Even in the 60's a lot of bikes had primary chains mounted outside the engine/trans that had to be oiled.

Interesting.  Shiney, on what page of the FSM do you see it?  I have a DOHC so I know our bikes are different, I'm just curious.

[shinyribs]

I'll find that page and get it up soon

Finally found it! Here is where the FSM describes the adjustment procedure for it.All I know is this is in the FSM,but it ain't on either of my bikes,the '76F or the '78K. I have looked. Pages 189 & 190 of the FSM.

Tools,dont hate meSees' made me do this! JK

[Re-run]

The oiler was discontinued after 74. Anything afterwards would not have it. A lot of people removed it and thats why you seldom see it on the earlier bikes.

[Thorby]

My '76 doesn't have the chain oiler.  I had actually been wondering about this matter for a while until I realized that my bike simply doesn't have it.  I see the point about not wanting to wreck an engine due to a chain oiler.  However, I'm a little panicky about my chain not being lubed right since I already broke one, which jammed inside the drive sprocket casing, opening a hole in the transmission shell.  Maybe that chain was about as old as the bike?

Chain inspection is part of T-CLOCS, which should be done before every ride (if you're the A-R type) or weekly.

Don't mind a little oil. Keeps the bike from rusting! :) Cleans right up with a degreaser.

They do exist. I guess I am going to have a big helping of crow. I went to do some work on my buddies new engine, for his POW/MIA bike, and when I pulled off the sprocket cover to mount it on my engine stand, there it was. This is a very low mileage K-2 engine, so I guess it was not on the road enough to warrant it being removed. I guess Honda was not as smart as I thought they were.

I eat crow constantly.You will develop a taste for it.Soon

If you get tired of the oil puddles and want to eliminate the chain oiler on so equipped pre-1974 models, remove the front sprocket to reveal the oil supply hole in the countershaft. I push about a 1/4" length of tight fitting o-ring material in to completely stop the oil from coming out then reassemble as normal. I saw the post with Joker Machine's plug kit, but am reluctant to "tap" anything into a threaded hole. If you want to remove the adjuster plug, why not use an automotive oil plug to replace it. The thread is 14mm x 1.25mm pitch, this is a common size that could be picked up at nearly any auto parts store and looks a lot more proffesional than a broken off spark plug as I've read some people use.
