Similar problem on my swinging arm NH350 some years ago, a very tight bend in the cable. I straightened the cable out by making an extended brake anchor plate which allowed the brake drum to rotate slightly anticlockwise.

Have now received the new seals, they are a slightly tighter fit in the seal carrier than the old ones but I put this down to the old ones possibly having slightly worn on the outside diameter due to their movement within the seal carrier. I still do not think that the tightness of the new ones is s...

Paul S, I will order some new seals and see if they are a tighter fit, if not I'll resort to fitting a spacer has proposed. Paul J, followed your suggestion and polished the surface over the length of the seal, came out very well with no measurable material being removed, see pics, the surface to th...

Although having renewed the stanchions, bushes and seals a few years ago wth little mileage since, oil is still getting past the oil seal into the upper part of the oil seal carrier, see fig 1. Note it has the correct top bush for the later stanchions. I suspect what may be happening is that has the...

If, as suggested, the spindles are hardened, you can check this with a file, then you will require someone with "spark errosion" facilities ie EDM "Electrical Discharge Machining". This process will create a hole through the hardened surface.

The eye bolt and its adjusting nut act as a "adjustable mechanical stop" (as opposed to a friction stop) similar to the ones that are fitted either side of the rear wheel, all three are essential to ensuring that both drive chains maintain their correct tension. It is therefore important t...

One of the problems with bolts and locking nuts in this type of situation is that when the lock nut is tightened it may cancel out the tightening affects of the bolt. The lock nut is applying an opposing force to that of the bolt and may change the thread seating faces, therefore has the bolt stretc...

When statically balanced with the above piston assemblies the crank assembly sh...
