Another wench question

Question for D6 Merv or anyone else.



My Cat D4E dozer has a D4E Heister winch on the back. It was mounted on the machine when I bought it. The winch seems not to be connected to the PTO shaft. With the access plate on the side of the wench removed there is no rotation of the input shaft.



Is there a way to look at the PTO coupler without removing the wench?



When the winch was installed was the shafts lined up and the coupling made as the wench was installed sort of like lining up the shaft of a standard truck transmission or was the wench installed and later the coupling put into place connecting the PTO to the winch via an access plate?



Could it be that the last person to work on the dozer just did not couple the shafts?



In other words do I need to remove the wench to troubleshoot the problem and see if the coupler is indeed installed correctly and / or why the input shaft is not rotating with the PTO?



I have been putting off repairing the winch long enough. It would be a shame to need the winch to pull the stuck dozer out with a non working winch.



This is a 27x direct drive machine



Thanks
