Hi, I recently bought a `68 S type 750 Commando with a variety of missing parts, I would appreciate it if anyone could tell me the length and diameter of the clutch push rod.
 
Congratulations but I wonder why you would care about such a thing ? They're all the same length and diameter.68 means you should be checking the frame under the tank for the support rail or not. Do you want to drive this or show it off ? Let us know.Photos ?
 
If you make it a quater in. shorter than that , and put a quater ball bearing at the adjuster end , there better . :oops:
 
Hi , and Merry Christmas.............!

According to the manual the clutch pushrod lenght should be:9.813/9.803 in (244.250mm/243.996mm)
OD: 0.237/0.232 in (6.019mm/5.892mm).......yes the idea of cutting it in two parts and fitting a 1/4 in ball (from a bearing say...) is a common practice , avoid it to flex and "could" restrain gearbox oil migrating towards the clutch, , though for that particuliar case the clutch pushrod seal improve the matter far better , but , you know , I had ridden my Commando for years without those fettlings and no bother ........then you become more paranoid when getting older !
 
Was just being a wiseacre . ' than WHAT ' , indeed . thankyou . and a 1/4 in is 6 .25 . IF it fits under the adjuster
is just to stop the end overheating and going soft . Though WE DONT hold the clutch IN at the Lights . DO WE > :p
 
I wondered what the clutch was for!!!!
Does any one change out the actuator lever at g'box/clutch cable side for an Atlas one and does it make the lever action softer?
Regards Mike

My bike came with the Atlas/Dommie lever and it took a long time to figure out why the clutch would not release fully. That and the uneven diapraghm fingers. It reduces pushrod travel by about 040" and makes the clutch so light that with the correct stack of plates and a Venhill featherlight cable its less than one finger, truly. 4 steel, 4 Surflex and that Venhill cable and the extra leverage of the Atlas lever is not needed, two fingers is easy.

Yes I did. Definitely makes the lever action softer, never had problems the clutch not releasing fully.
1/4" = 6,35mm

FWIW, do not try to make your own clutch rod unless you are experienced in heat treating and can verify the hardness of the ends that you heat treat. Material requires tool steel/drill rod. Drill rod is not easy to find and it is hard to buy less than 10'.
From $10 to $15, save yourself some trouble.

I have made feeble attempts to making this item. If the end mushrooms too much, the gearbox will have to be disassemble to some extent to remove it. A lot of stress is involve here and the heat generated is to much for anything less that than a very high Rockwell #.
