Adjusting Chain Oiling System Brush Flow (up to S.N. 49999)

Whenever necessary, the oil flow at each brush (A) from the chain oiling system can be independently adjusted. As a matter of fact, brush oil flow is regulated by metering valves (B) with different restriction diameter.

Five valve types are available:

  • IM22 10 cc/hour
  • IM23 20 cc/hour
  • IM24 40 cc/hour
  • IM25 80 cc/hour
  • IM26 160 cc/hour

NOTE: Valve output is given at 700 kPa (7 bar; 102 psi) with John Deere BIO-MULTILUBER-OIL at 25° C (77° F).

The different metering valve types are available through regular parts channels and can be installed at any port of the manifold (C) to regulate oil flow of the relevant brush.

Proceed as follows:

1. Unscrew fixing nut (D) of plastic hose (E). Pull out plastic hose.

NOTE: If plastic hose has been marked by the metering valve sealing components, cut the hose just above this mark so that no oil leakage will occur when installing hose into a new valve.

2. Remove metering valve (B) from manifold (C). Install and tighten a new metering valve instead, then insert plastic hose (E) back in metering valve. Slightly tighten fixing nut (D) just enough to get no oil leakage.
