A spring recoil assembly (20) for use in a crawler type track roller frame (12) includes an elongated tubular housing (28) (46) having opposite open ends, a stop (36) at least partially closing one of the ends, a compression coil spring (30) within the housing and abutting the stop, a radially inwardly directed lip (48) on the other end of the housing having an inner diameter greater than the outer diameter of the spring, and an additional stop (52) within the housing other end and with, the first stop, sandwiches the spring within the housing. The additional stop has a periphery sized to freely pass into the housing past the lips. A retainer (60,62) is positioned within the housing between the additional stop (52) and the lip (48).
