What is divorced transfer case?
A divorced or independent transfer case is completely separate from the transmission. It is located further down the driveline than a married transfer case and connected to the transmission output shaft by a short driveshaft.
What is a NP203 transfer case?
The NP203 is a heavy, chain drive transfer case that has a gear drive low range section mounted in front of a chain case. An open, inter-axle differential located in the rear output section splits power between the front and rear axle. These conversion kits basically eliminated the inter-axle differential.
Which NP205 for Doubler?
2 days ago
Input Bearing Size ORD bases its Doubler on a TH400-style NP205, which utilizes a larger/stronger 90mm input bearing. NP205s with the small bearing will require case machining in order to build a Doubler. This is an easy job for most machine shops, but it does represent an additional expense.
How much does a transfer case cost?
The transfer case is also capable of synchronizing the difference between the rotation of the front and rear wheels. Transfer cases may contain one or multiple sets of low range gears for off-road utility. Typically, the average cost for a replacement is expensive, between $2,389 and $2,500.
How do you identify NP203?
The NP203 is identified by several features: 1. The transfer case is made up of 4 sections bolted together, a range box (the gear reduction we use for the Doubler kit), the chain case which houses the chain drive to the front driveshaft output, the differential housing, and the output housing.
How does a NP203 work?
The NP203 were originally a full time 4WD case, meaning all 4 tires receive power at all times. This was made possible through use of a differential in the back of the 203 that let the front and rear driveshafts turn at different speeds as just as a diff in an axle lets each axle shaft turn at a different speed.
What is a NP203 Doubler?
For more than 11 years now, Off Road Design (ORD) has offered a NP203/205 Doubler kit designed to multiply the low-range gear ratio of fullsize trucks and SUVs. This combination of gearing vastly improves crawlability and torque multiplication without adversely affecting high-range cruising speed and engine rpm.
What is a NP 205 transfer case?
NP-205 TRANSFER CASE. 1. The transfer case is one piece of cast iron. There is a short bearing retainer/output housing at the tail of the case, and aluminum bearing retainers/seal retainers at the front and rear outputs but the working parts are all in a single iron housing.
What is a divorced transfer case?
Divorced/independent. A divorced or independent transfer case is completely separate from the transmission. It is located further down the driveline than a married transfer case and connected to the transmission output shaft by a short driveshaft.
What is transfer case repair?
A typical transfer case service includes an inspection, removal, and repair or replacement of the gears, bearings, gaskets , seals and transfer case chain in the transfer case. Transfer Case is one of the most important components of four-wheel drive vehicles.
