Taking apart Lead joint on 4" Cast Iron pipe.

[joni os]

Vertical soil pipe in 4" CI. Connections below collar I would prefer not to disturb.
Any advice on dismantling lead joint at collar.

Don't, unless you are removing all the lead

Easy enough you need a big blow lamp heat joint till lead starts to melt and Flickr it hot with an old screwdriver or similar easyest if thjere a length above to wiggle it loose Beware the yarn will come out flaming
