Application:
These hardened-steel split cotters (quantity 2 per valve) lock the
spring cap to the stem of inlet and exhaust valves on Perkins
4.236, 4.248, 6.354, 1004-4, 1004-40, 1004-4T, 1006-6, 1006-60T and
CCW6.601 engines; they are therefore used in Massey Ferguson
165-399 tractors, 30-50 back-hoe loaders, 550-890 combines, Landini
7860-8880 row-crop tractors, JCB 3CX/4CX back-hoes, Claas 65-75
forage harvesters, New Holland 1116 swathers, 1495/1496
mower-conditioners, Volvo BM 2200 forklifts, FG-Wilson P100-4 &
P135-4 generator sets and a wide spread of irrigation, construction
and marine auxiliaries that use the above engine families
world-wide.
Technical specifications:
The cotter is die-forged from 65 Mn spring-steel, heat-treated to
48-52 HRC, 8.9 mm ID, 5.0 mm OD, 6.0 mm overall length and 45°
included taper; the split design gives 0.15 mm radial grip on the
valve groove, preventing cap walk at 6 000 valve lifts per minute.
Weight is 1.6 g per pair and the parts are supplied oiled and ready
for installation.
Material & performance features:
The contact faces are precision-ground to Ra 0.4 µm to eliminate
micro-slip, while a manganese-phosphate coating gives 96 h
salt-spray resistance and aids initial bedding-in. The design
maintains clamp load within ±5 % after 5 million cycles,
eliminating valve-stem wear and spring cap loosening under severe
stop-start agricultural duty.
