Clutch Ratchets

[Guest Bobbers]

Hi are all yellow clutch ratchets the same cos mine is rarther worn out and ones on eBay say 45 mm ?? .

[maccavvy]

I always thought they were colour coded

[jaimo]

Yeah white. Yellow. Brown and black i beleive could be wrong i usualy am

[cb750]

Some of the pattern ones are black no matter what the size!

[Peter Bell]

Here is a picture, the red is a 45 don't just go by colour!

[Bob Tucker]

Most of us found the 45mm doesnt allow the clutch to clear properly.

I use a 55mm one......coloured black, but it was a pattern one from a local factor.

[Guest Bobbers]

We're do you measure from ?

[Bob Tucker]

I think ts the radius from centre to the bottom of the cable groove mine had 55 mm printed on the packet it came in

[Guest Bobbers]

Thanks I reckon a 55 would do as long as the ratchet is the same size just a shallow groove on the 55 will give more movement on the cable , as clutch always bit early

[Bob Tucker]

The overall size of all the quadrants is identical, so the ratchet mechanism works.

The only difference is the depth of the groove the cable sits in.

You could try this one from an orion. 55mm but I can't be sure shaft diameter.

Search ebay for 'ford clutch ratchet' or 'ford clutch quadrant'.

Or even this one at 58mm.

As Bob said above they all seem to have the same centre to teeth diameter but different groove diameters. (I hope) So positioning of the two hooks to hold the cable end gives an idea of groove diameter.

I never knew they came in different sizes..

 

I might look to replace mine at some point, but what I did was put some copper break pipe in the grove.

It fits nice and snug and increases the radius.
