Power Take-Off: Description and Operation
General Information
The NV 021 PTO adapter provides power take-off capability for BR models with an automatic transmission. The adapter is available as an option on
2-wheel drive 2500 and 3500 models.
The NV 021 adapter is similar in appearance and mounting to a small transfer case. A 4-wheel drive automatic transmission is used to simplify adapter
mounting. The adapter has mounting studs in the front case for attachment to the overdrive unit gear case.
Basic components consist of the front case and rear extension, mainshaft, input gear, PTO gear, shift sector, and shift fork, shift rail and sleeve.
The mainshaft is supported in by a needle bearing in the input gear hub and by a ball bearing in the rear extension. The input gear is supported by a roller
bearing in the front case. The PTO gear is splined to the input gear and is retained by a snap ring.
The input bearing is secured in the front case by a retainer. The output bearing is secured by a retaining ring on the mainshaft and by a second retaining
ring in the rear extension.
The speedometer drive gear is located at the rear of the mainshaft. The gear is secured on the shaft with two snap rings.
