Mamod SL1 / MSS Loco Changing Reverser Block

[Modelenthusiasts]

Can you help me please?

I need to remove the forward/ reverse block (to find out why there is no steam to one cylinder) from an old Mamod SL1 and I'd like to know the favoured method for an old engine.

Any advice would be welcome.

Remove the front bolts on the cylinder assembly and with a bit of wiggling it should drop out. You nay need to release the steam pipes.

It possible to do by the method Jim has mentioned but I usually end up taking the body off the chassis.

However, I would leave the reversing block where it is and take the cylinders off, that way you can see all the passage ways and look through the reversing valve. If it hasn't been run for a long time its possible that old oil has set in the passages.

If you are going to disturb the reversing block get two new 1/4" x 1/8" replacement O rings to seal the pipework. The existing ones go hard after a time and then leak steam if they are moved.
