replacement block or repair of blocks

[Killick69]

I have 3 Ronstan blocks that are in good shape, except for the white inner plastic sheave(part the rope runs on). I have not been able to find these blocks on the Ronstan website. Please excuse me if I am using the wrong terminology. They are Ronstan RF 984 blocks that run on a track. The application on my TH is on the boom. Perhaps Ronstan has discontinued this range of tracks and running blocks, does anyone know? Perhaps replacement sheaves are available and it should not be too hard to fit new sheaves with new shafts (stainless steel bolts).

Cheers, John

John,

Ronstan do sell the sheaves, see

You can file or drill off the rivet head pivot of your old block and measure which one you want.

Or go with a new type!

Cheers,

Tom

Phoned Ronstan today and they told me it is an obsolete block (no big surprise). Sadly the closest replacement is just a single cheek block, not an adjustable type (not the running type). So it would have to be mounted onto my old runner. I am going to have a go at filing/grinding/drilling and hopefully can replace the sheave.

Cheers, John
