Clutch Master Pushrod From Pedal


Best Answer baldric , 30 December 2013 - 09:44 AM

well the whole system is working now  which proves I was on the right track the return spring on the clutch lever arm is very important it has to return the slave cylinder  piston completely into the slave cylinder  and also set up all adjustments to factory specifications   now that's sorted this winter in the new country  the mini will be getting a complete rebuild  / restored

hallo ethel

its a clubman style   very light weight  no strenthing  gussets   . I have come across various difrent designs    ,,,((  those push rods wernt mine I picked the image up of another site )) ,  and can not really vouch for them     but it does go to show  how things get canablised around ,,,

 greas nipple  I had to do something  to lubricate the cluster pedal  pin they never get any lubrication ,,,  whilst I had the mess all in bits I had to do some small mods  to get the whole thing back in tolerances    that I could live with,   the machines that I have  its an easy job ,  being retired I have some free time

 

I have owned( 2) 1100   and for the life of me I cant remember much about them  I also had a reasonably good shell  which I built into reasonably good vehicle  from the nackered  unit

all these images are of the total rebuild of the pedal cluster    no boots have been fitted yet    only one problem , the whole thing is a bit tight  all machining is ok  its just the paint  that making it tight   

 

Attached File  P1020094.jpg   115.28K   4 downloads    the rebuild of these parts requires  a  mig   lathe,   drill press , and a milling machine , and reamers,,,  lathe to turn up the cluster bolt    and new clevis pins  ,,, the mill to surface the brake cylinder   ,,, mig to  go over the cracked welds on the bracket  and to wejd new side pads on bracket   ,,, 5/16"  nf  die   for threading   ,  various files and a 4" inch grinder  and discs   its advisable to know some one with this sort of equipment   ,,, like a model  engineer who isent going to charge you an arm and a leg

 

the cluster is all ready to fit in place   just wating for daughter to get back from the mine   its her job yo fit the cluster  with me as a mentor  

 

once fitted I will be back  to scribe my findings  ,,,

to day I spent all day in setting the clutch cluster pedals up with my daughter as an apprentice everything went in reasonably well and easy and the clevis pins fitted quite easy especially with the locating tool that I had made up even the split pin puller worked ok reason it had to come out I fitted the brake cylinder and forgot to add the engine steady plate ! apart from that its a simple job to do all pipe work in place slave cylinder set up using all the old neoprend pistons cups , same with the master cylinder , all those things will be renewed in the major rebuild of the mini along with a host of other bits , slave cylinder I used the standard size pushrod , (not that silly extended pushrod) that some silly mongrel had extended (another as kicking job , with everything in place it was time to blead the system , this is what took the time to get every bit of air out of the system and setting up the clearances as per factory recommendations , that was fiddley and time consuming . I required every bit of the master cylinder push rod movement to be transferred to the slave and also to slave cylinder push-rod had to transfer as much of the slave cylinder piston movement a possible well I got the movement up to around 9/16 of inch ,,, still not good enough ,,, the next problem was the clutch return arm spring which was very tired although fitted correct was not returning the lever piston rod right back into the slave cylinder took me a bit of time to tumble to this problem ((just a matter of pushing back with the finger on the end of the clutch lever arm so that the clutch slave cylinder push rod went further back into the slave cylinder)) this means a new spring ((or a modified clutch lever bracket to hold the spring in place )) the small dufachat that fits on the end of the clutch lever arm to hold the spring in place ,,, with all that in place and working as it should . I get a nice stroke from the slave cylinder 3/4 inch this is what I expect and nothing less ,,,this is the master and slave working as they should and with the standard slave cylinder pushrod ,,, if a bloke has to extend the master cylinder pushrod HE HAS BIG TROUBLE and if he does not do the job correct he is wasting his time and money ,,, mind you I have the equipment to do the job ... and if a bloke is careful he can achieve very near to my measurement by hand work ,,, machines only make it easier the whole job now is tight no slack in moving joints the next job to do is bleed the brakes and get the steering column back in place and soddin seats in ,,, that's another cockup , and then to start the motor and see what happens still keeping my fingers crossed that the lever will move the gears in place without a nasty crunch I am just hoping that I don't have clutch spin in my day I knew it a a frozen clutch so until my daughter myself and jayson turn the key we wont know ,,, a little story . I heard from a mini motor parts supplier the person advised the purchaser of a clutch slave cylinder ,(if you don't get the required travel on the slave cylinder push-rod remove the circlip ??? ) don't believe what any one says and so called experts ,,,and I aint no expert so its all open to conjecture ... I will be back when the key has been turned with my final findings
