MG Midget and Sprite Technical - Clutch slave cylinder arm
| Hi, Just in the process of changing my clutch slave cylinder 1275 gearbox but the new push rod i purchased seems significantly shorter that the old one , is this correct ? It look as if the old one may have threaded into the slave cylinder piston but the new one buts against it is that correct , can anyone advise Thanks Andy  |
| Andy Chaffey |
| Also clutch arm has a slight bend in it is this correct , again i can't remember or is it out of shape cheers Andy  |
| Andy Chaffey |
| clutch plate wears and thrust bearing wears, so PO treads ever more heavily on the pedal, eventually bending the arm. Once bent it's bodged with a longer rod to get back to the right position. Find a straight arm before refitting! |

| David, Thanks as always for your help , just so i am clear , does the smaller rod look like for standard ? and if so i just find a straight arm and should be okay ? cheers Andy |

| The new rod looks about right. I assume you ordered the one for a 1275cc engine? The 948 and 1098 ones are a different length. |
| Bob Beaumont |
| Andy the correct rod is 13H3655 and my spare measures 2-3/4" from eye centre to the end. |
| David Smith |
| Andy, Found exactly the same when I stripped mine during the reshelling. Needed as David has noted new arm and correct pushrod. Check all the clevis pins/holes are not worn including the master cylinder end. R. |

| Bob , David cheers just measured it , its the right one , will start the hunt for a straight arm tomorrow !! have one spare box so there might be a better one on that hopefully Cheers Andy |

| with a bit of heat you can hammer it straight(er) - basic blacksmithing really. I've seen racers weld a length of square bar down the back of the arm to add rigidity. |

| PS - if you get stuck for an arm I have a couple of spares.... |
| David Smith |
| David, cheers , will have a look tomorrow and let you know |
| Andy Chaffey |
Yes I've had this problem too

So you put it on the barbie

| ....and when its almost done, you persuade it gently back into shape with an engineer's hammer. I did this as I was told the clutch arm was NLA.  |

| David, Just mailed you cheers Andy |
