Thread: 110 County drivetrain- observation and question

if youve got drums on the rear you might be grabbing one of the shoes on a slightly out of round drum.

Due to the nature of the crown wheel and pinion setup there will be a slight change in resistance in when you turn them against the normal direction of rotation but its goingto be less than a poompteenth.

Dropping the rear propshaft off wont isolate out the sailsbury but it will remove the Center diff and the parkbrake from the equation.

I think from the description it is probably one brake shoe a little too tight on the wheel - easy to check by simply backing off both brake shoes. Could be the handbrake, try the same, although since there is only one adjuster, if one of the plungers is rusted up, one shoe may not come back.

If a shoe is touching the drum, rotation in one direction will be easier than the other, as the shoe pulls on in one direction and off in the other. It is also possible, if you have both wheels jacked up, that the dragging shoe is on the opposite wheel, and turning in one direction allows the opposite wheel to turn, but the other way stops it so that the prop shaft has to turn, which gives more load, since you are working through a step up gear looked at form that way.

I hope you can understand that - I just reread it and it doesn't look too clear!

It turned out to be the hand brake drum. Now the strange thing is when I adjust it, its fine going forwards but to prevent the shoe/s binding in the reverse direction, I have to back the adjuster on the drum off so much that I have no handbrake at all, even with the cable fully adjusted Any ideas?
