TM 9-2350-273-BD TRACK AND SUSPENSION 9-12. ROADWHEELS. a. Operating with less than the standard number of roadwheels will do two things; One, it imposes heavier loads and therefore increased wear, but this will not be measurable over several battlefield days. Second, it will reduce the number of “slots” available for center guides and alinement of the track. Assuming that only roadwheels have been lost and all arms are functioning, it is better to operate with single wheels in some positions than to leave a position completely blank. Two rules should be followed First, if possible, do not put two single wheel positions next to one another. Second, when single wheels must be consecutive, make them alternating single inner and single outer. b. Wear plates are desirable but not critical. Missing wear plates will significantly shorten the life of a wheel but a wheel should still last several battlefield days. c. At least two roadwheels bolts can be missing in non-consecutive positions. 9-13. ROADWHEEL/HUB DAMAGE General Information: The tank cannot operate if specific roadwheels are damaged. The M48/M60 tank can be operated in a degraded mode if it is equipped on both sides with a rear sprocket, an idler wheel, a center or a front and rear track support, roadwheels 1 and 6, and two other nonadjacent roadwheels such as 2 and 4 or 3 and 5. All suspension system components can be replaced, if the bearing seats in the hull are serviceable. If a roadwheel in a required location is damaged, it may be replaced with an undamaged roadwheel taken from a position where a roadwheel is not essential. All roadwheels are interchangeable. Vehicles are still operable if all rubber on wheels and track supports are lost; however, the track must be adjusted to compensate. Limitation= ● Degraded mobility Personnel/Time Required: ● 2 soldiers ● 1-2 hours Materials/Tools: ● Length of pipe ● Bar steel ● Four inch diameter wood Other Option: ● The M1 tank roadwheel will mount on the M48/M60 series vehicle roadwheel hub. M 1 tank roadwheels must be mounted in pairs on M48/M60 series tanks as they are smaller in diameter. Procedural Steps: 1. Inspect to see which roadwheels are damaged. 9-9
