The Cirta drive pinion shaft carries the pinion that drives the rear axle crown wheel. When its teeth or splines are worn, the transmission becomes noisy and develops play.<\/p>\n\n\n\n

Compatible models:<\/strong> Cirta tractors (Sonacome).<\/p>\n\n\n\n

Specifications:<\/strong> toothed drive pinion shaft.<\/p>\n\n\n\n

OEM part number:<\/strong> 8140.6.<\/p>\n\n\n\n

Part sold under the Valmy France brand. Send us a photo of the old shaft and the number of teeth: we check the match before shipping.<\/p>\n\n\n\n\n\n\n\n

The drive pinion shaft transmits all the torque to the rear axle. When its teeth or splines wear, the axle becomes noisy and play increases.<\/p>\n\n\n\n

Identifying your Cirta drive pinion shaft<\/h3>\n\n\n\n

This shaft fits Cirta tractors. Count the pinion teeth and the shaft splines, then compare the length with the old part. If in doubt, send us a photo from the contact page<\/a>: we check the match before shipping.<\/p>\n\n\n\n

Fitting it correctly<\/h3>\n\n\n\n

The pinion and the crown wheel work together: always check both. Fit the shaft with bearings in good condition, then set the preload and the pinion-to-crown-wheel backlash as recommended. Finally, refill the axle with fresh oil.<\/p>\n\n\n\n

Why choose Valmy France<\/h3>\n\n\n\n

Our shaft is machined from the original part. And we work directly, at a fair price. See also our other agricultural transmission parts<\/a>.<\/p>\n\n\n\n
