A minor part of these bulldozers, but I found
PDFs of original manuals for the winches used on the D6A and D7A:
The serial numbers indicated are technically not for the armoured versions, but the D6A was basically a D6-5R with an armoured cab and hydraulic dozer blade and the D7A was a similarly modified D7-7M, so I doubt the winches would have been very different.
Edit: I just realised that site is making linking to the right page difficult. In the menu on the left, choose
Allied Winch → Operator’s Manuals → Archive to find the ones I mentioned above.
