• Manual operation.

• Sequence testing which will result in a differential characteristic map.

• Quasi-transient testing, a combination of closed/open-loop testing within a

time domain to analyse differential response.

Output data is available in various recognised formats. The data recorded in the test

can then be used to accurately set up the differential to best suit the customer

needs, significantly reducing track testing time.

The QT-DTR is available for rental use on a daily basis including Xtrac technician

support. Xtrac will design and manufacture the appropriate tooling to mount the

customer’s differential onto the rig and, in conjunction with the customer, determine

the most appropriate test strategy and procedure. Testing is then undertaken and a

fully documented results package is available as required. For more information or to

arrange testing, please contact your business manager.

5. Gearbox Assembly and Maintenance

5.1. General Assembly Notes

Only genuine Xtrac parts should be used when overhauling the 1152 gearbox. Key

steel components manufactured by Xtrac are made with our own specification of

steel, either X36C or XVAR1. All Xtrac components are manufactured to our own in-

house quality standards and are inspected at multiple stages of manufacture.

It is good practice to replace all lip seals and k-nuts after removal. O-rings, the oil

filter, circlips and bearings can be reused, but they must be inspected regularly and

replaced as soon as any sign of wear or degradation is evident. A consumables kit

1152-981-005A is available, containing all o-rings, seals, nuts and washers which

should be replaced on a regular basis when carrying out a scheduled inspection.

Lightly oil the parts before assembly and do not use any lubricants other than those

stated in this manual.

The oil filter fitted to the 1152 gearbox must be replaced at least every 6000km

(3728 miles) or sooner if debris has started to collect. The filter is situated on the

suction side of the pump, so any blockage will manifest as a reduced pressure in the

feed lines to the gearbox oil feeds/sprays.
