Update for NRE55343

Lube Oil Pump

This update is for 3135, 3152, 4180, 4202, 4219, 4239, 6303, 6329 John Deere engines. The NRE55343 lube oil pump is not new to the market.

Reliance is providing this update for all of our customers. If you are installing this lube oil pump in one of the above engines, you may run into one of the following problems: 1) The back cover is different, 2) There is no port for the lube line that goes to timing cover, 3) There are four bolt holes in the pump housing, but only three bolt holes in the cover.

1) The cover on the old style lube oil pump has the oil pump pickup and back cover all in one section. If your lube pump has the old style cover you will need to obtain a new oil pickup tube and O-ring. Pick up tube part # is AR60701 and O-ring part # is A4730R from John Deere.

2) When using this lube oil pump in an engine that has the lube oil line to lower idler gear, you will need to discard the lube oil line and clamp, as it is no longer used.

3) Depending on the timing plate that you are using, there can be three bolts used or two bolts used. DO NOT attempt to drill a fourth hole in the cover. This hole has been eliminated to remove interference on some applications.

All bolts get torque to 50 NM (35 LB-ft).
