Generator No2 (Two Speed Generator) - replacing fixing strap


Recommended Posts

Hi All,

 

Some clever clogs when replacing the Generator on our Ferret bent and fractured the holding/belt tensioning strap of the Generator in order to replace it.

 

The first picture shows the fracture and the second shows the pin that needs to be removed to renew the strap. The problem is how to remove the pin which is held in two aluminium lugs which are between the generator strap.

 

The wrong method will cause the lugs to break - anyone know how to get the pin out using the correct method?

 

 

Thanks D&J

Griff,

 

Whilst it is possible to support one lug whilst tapping the pin the other will not be or at least it will potentially move until stopped by the strap as there is a clearance between the strap and lugs longitudally.

 

Is the pin an interference fit in one or both lugs?

 

BTW if anyone wants a really good battle try removing the generator clamp bracket with the engine in situ on a Ferret -

 

Top bolts shouldered 5/8" AF Socket (Top Right cannot be totally removed until all other bolts are removed)

Bottom bolt shouldered 5/8" AF Socket

Centre Bottom 1/2" AF not shouldered

Bottom right Behind the oil tank - 5/8" AF use a clawfoot socket

All bolts with spring washers fitted and TIGHT

heat and correct size punch heavy riveting block at end of strap to provide reaction force. or if room the G clamp and socket method.

Looks the same as a champ one where there sould be split pins either end to hold the pin in as it should be free in the lugs Mine was a ******* to get out lot of heat & big hammer didnt break the lugs but they got bent soon straightened

Thanks Chris,

 

No split pins visible, but I'll wire brush the lugs and make sure there are no pins through the pin. Then attack as suggested unless there are any further suggestions?

 

By the way did you change it for the same reason? fractured metal clamp ?

Just heating the lugs may allow them to expand enough to let the pin be driven out gently.

Easy as you go...... :undecided:

 

For assembly, you could ream the lugs to make the pin a sliding fit and then cross-drill one lug/pin and use a roll/split pin for retaining in future. Mind you, how many times do you intend removing the pin from now on.... :D

Dear All,

 

Thanks for all the useful advice!

 

There are two types of adjusting device for the engine fan belt. The latter which I have just received today is more in line with later practice of tensioning the belt.

 

The lesson learnt is do not bend the generator fixing clamp when removing or installing a generator. (and No I didn't but some cowboy did)

 

Picture of both adjuster to follow
