Hey all
The coupling that connects the prop-shaft to the gearbox on my 5/7 has failed.
Does anyone know where I can find a replacement?
Thanks
Sean

Sean,
Your best bets are to find somebody with lot's of spares. Sorry I don't have any Blaxlands.
Or get you local machinist to make one up.
When you have the replacement check the shaft alignment. |

Depends on your skills or those of your contacts.
Options include -
Locate original 'spare'.
Pattern + casting + machining (preferred).
Turn from steel or cast iron bar (preferred).
Weld disc to boss and machine (OK).
Force fit bored flange to turned boss with scotch key (not preferred).
In all cases, remind machinist to bore boss and face flange on one setting and to provide a generous fillet. |

sorry to drop on your thread Sean.
Misalignment will cause this type of damage,make sure every thing is perfectly aligned (+ .003 max)
Andy I have being trying to email you ,but something is not quite right in my pc.
Can you ring me?
Cheers Todd.
PS Sean what size is your shaft,I have a couple of couplings |

Hi Sean
Are you still looking for that part?
I have one attached to a 3/4 s/steel Shaft, It may be frozen on but will be OK if the shaft is long enough.
Where do you live? |
