Information as to how to remove the cab of a Hartland Loco Works 'Mack' switcher

Gently pry the two clear light lenses out. They have very long stems which hold the roof in place. This will help later. The  cab is held on by two screws from underneath. The motor block must be removed. It is held on by two flanges (flanged tabs, actually), one at either end of the block. Turn the loco over and locate the flanges. One of them is squared while the other has a slant to it. GENTLY work a flathead screwdriver between the flange and the block and lever the flange away until the motor block comes loose. There is a long vertical brass rod holding a single light bulb loosely attached to the top of the block. Take care to pull the motor block out carefully. You should be able to see the two screws that hold the cab on under the frame. At least I think that's how it's held on! It's been a while since I looked at one. I'd better check!
 
Having checked  -   you should be aware that  removing the cab is the right way to get the bonnets off as well. The motor covers are held in place by a tab that fits under the cab. Removing the roof is the best way to get at the interior/windows.

Chris also sent some photos here they are with the text he has added.



Make sure that your CAREFULLY pry the angled tab: do it carefully otherwise it will break.


Hers  a clearer view of the motorblock sitting in the frame. The block is already free and moved back to view the flanged tab.



Here's the two screws holding the cab on. Be aware that there are two metal weight plates in there as well that will drop out when the cab is removed.

If you remove the motor block, and then remove the cab, you can push out the clear plastic rods for the lights on the cab from the inside, no prying needed.

These plastic rods are what keeps the roof on!!!


Thats it!
