Ceturies ago , after having endured a lifetime of throwing out of gear , usually second , at maximum tourque ,-
How it never blew apart is unknown .- and the odd marvelous grauch clunk using the heal to reingage , -
still holding a Z-1 after the second ' occurance ' ,
Some Time later ' we ' removed the index plunger , and thought squeezing it that the spring was a bit soft . Quite So ,
A good tug had it two or three times its existing length.
So a good sqish got it back 1 1/2 or more , Still fittable with a bit of dexterity .
The comparison in shift was it was then a good deal stiffer , bot the ' indexing ' was decidedly more pronounced .
And the ENGAGEMENT was definative . Descernable with the toes .
So to get all worried when shuch primative efforts produce decided rewards , would be missleading in many ways .
Id think initially , a ' Good ' tension would be a bit indeciseive stationary , but decidedly observable rolling .
Scnick Clunk like .
If youve got the cam plate out , doing the Mert Lawill massage with the eyes , a finger tip , and deburring with a stone if required ,
then polishing the track . Or Tracks ( for the selector rollers ) seeing that theres no binding or rough spots . Nor excessive clearance .
Remembering that the 500 cam plates had dual reinforcing straps welded acoss the cam plate ,
it may require a tap here or there to remove slack to ensure accurate engagement . Like a well oiled whatever .
The NZ terrific poll ease had WW1 era lace up knee length boots , and didnt get along with their Triumphs or their gearboxes,
unless endowered with unusual degrees of sympatico . A rider on the Commando endowered with this footwear would
inadvertantly produce a grauch at every shift . Clod Hoppers rather than toe action . Toes being comparable to fingers in sensitivity.
Except amougst truck drivers . Who may not posses toes as such .
Thus its not unkown for a previously employed transmission to be brutalised .
HOWEVER , being robust as Triumhs generally are , at least in the larger twins,
If its not making metal , it is likely generally sound ,
but would likely benefit from selective fettling , as previously mentioned .
And now you know why .
Not to detract from previous advice .
Looking at the spring , AND its operating length range , there should be firm and steady ( even ) pressure Through that range .
If it only firms up through the lower part into the plunger housing , theres your probllem .
And as its shot , giving the sping a fair heave will enable you to decipher its properties .
So if like mine it stretches ludicrously , by the time you manadge to get it short enough to refit ,
the sping pressure will likely be good , and ease in correctly within 20 miles of fitting .
i.e. the shift action may be a bit stiff initially , but itll soon find its room .
Recalling the pre unit were I think more coils of a slightly ( 20 % ? ) thinner wire .
Once bitten twice shy . You want say 3/4 inch of compression , fitted . For a good shift .
As was the wont after this humbling experiance ! .
( always save and inspect the oil s after changes , and setting for some hours. As to if theres any metalic contamination .)
