Terry Michael was the inspiration behind the triumph as his early two try burst put his side in charge, but it was a fine team performance which sealed an important victory.
With debutants in winger Shane Davies and centre Ryan Hammond and Rob Rose earned his starting place alongside Wood in the second row, the visitors might have been expected to take time to settle but they were straight on the offensive as the Aldwinians kick off was taken cleanly by Rose before a deep clearance kick by Richardson turned the home players around.
An excellent chase from Crocs forced a hurried pass from the home full back which was intercepted by Michael who sped home for the opening try, then Richardson's strong drive into the heart of the Aldwinians defence forced them into an offside and Joel Hinchliffe's conversion stretched the lead to 8-0.
Back came Aldwinians and a Waite clearance kick was charged down resulting in a try for centre Thompson which Worrell converted to pull his side back to within a point.
But Crocs went straight back on the offensive and though Hammond was pulled back for a forward pass, the Crocs front row of Thomas, Wheale and Day turned over the resulting scrum and set up a lovely blindside break with Shane Davies passing back inside for a second Michael try which was converted by Hinchliffe.
Adam Hinchliffe then combined well with Richardson and Waite before crossing himself, the conversion making it 22-7.
Crossleyans captain Chris Seymour was determined to keep his side focussed and they extended their lead when Mark Thomas allowed Wheale to float a pass out to Davies who scored in the corner, and a powerful break by Waite was finished off with a try from Thomas to hand the visitors a 32-7 half time lead.
The second half started with a reshuffled Crossleyan back line, Waite being replaced by Duffy, and Rob Oliver coming on for Michael, and another Hinchcliffe penalty added to home woes.
And Crocs underlined their superiority in the closing minutes when Richardson broke free once more and passed to Hammond, and after the ball was recycled by good work from props Richard Thomas and Andy Day, the tireless Adam Hinchcliffe crossed for the final try.
