After some discussion, I concluded that to fit these heavy items safely in an awkward situation was not going to be easy and required the preparation of some special tools to assist. It was going to be quite a complicated process to be able to get the chains into position mid-way between the sprockets and then get the chains over the sprocket teeth so that the two ends could be joined.
The first tool is a trolley to carry the chain under the loco.
|Trolley with chain in position|
|Ready to go under|
|Chain 'slippers' in place|
|Axle sprocket with slipper|
|Ratchet & static straps on drive sprocket|
|Ready to drag chain over slippers|
|Secured from slipping back|
The same process was then applied to the axle sprocket and the two ends pulled together with a light duty lorry strap.
|Ends pulled together from afar...|
|...and from anear with both slippers removed|
This photo shows that even that was not going to solve the problem.
|So near yet so far!|
