Abstract
Automotive engine leaking from a crankcase seal in a gear train housing can be collected and returned to the crankcase oil pan before it contaminates the transmission fluid by means of a device which serves to collect the leaked oil in a reservoir which is isolated from the transmission fluid and which is continuously drained.

A device for collecting automotive engine oil leaking from a crankcase seal located in a gear train housing which serves to partition an automotive transmission located on a transmission side of the gear train housing from an engine crankcase oil pan located on a crankcase side of said housing so that transmission fluid residing in the transmission side of the housing is not contaminated by the leaking engine oil, wherein said device comprises a plate-like housing having:
- (1) a circular hole for permitting free rotation of a crankshaft/flywheel which extends into said hole;
- (2) a front surface having a plurality of holes for receiving means for mounting the device to the transmission side of the gear train housing;
- and
- (3) a rear surface having (a) a concave depression which serves to form a bottom of a trough into which oil leaking from the crankcase seal collects and drains directly from the transmission side of the gear train housing to the crankcase side of the housing without being further retained via a hole located in the gear train housing between the crankcase seal and the bottom of the trough and (b) a rim surface which abuts against the transmission side of the gear train housing when said device is mounted to the gear train housing.
A device for collecting automotive engine oil leaking from a crankcase seal located in a gear train housing of a diesel powered bus which seal serves to partition an automotive transmission located on a transmission side of the gear train housing from an engine crankcase oil pan located on a crankcase side of said housing so that transmission fluid residing in the transmission side of the housing is not contaminated by the leaking engine oil, wherein said device comprises a plate-like housing having:
- (1) a circular hole for permitting free rotation of a flywheel which extends into said hole;
- (2) a front surface having a plurality of holes for receiving means for mounting the device to the transmission side of the gear train housing;
- and
- (3) a rear surface having (a) a concave depression which serves to form a bottom of a trough into which oil leaking from the crankcase seal collects and drains directly from the transmission side of the gear train housing to the crankcase side of the housing without being further retained via a hole located in the gear train housing between the crankcase seal and the bottom of the trough and (b) a rim surface which abuts against the transmission side of the gear train housing when said device is mounted to the gear train housing.
A method for collecting automotive engine oil leaking from a crankcase seal located in a gear train housing which serves to partition an automotive transmission located on a transmission side of the gear train housing from an engine crankcase oil pan located on a crankcase side of said housing so that transmission fluid residing in the transmission side of the housing is not contaminated by the leaking engine oil, wherein said method comprises:
- (1) providing the gear train housing with a plate-like device having a circular hole for permitting free rotation of a crankshaft/flywheel which projects through the circular hole;
- (2) providing the plate-like housing with a front surface having a plurality of holes for receiving means for mounting the device to the transmission side of the gear train housing;
- (3) providing the plate-like housing with a rear surface having (a) a concave depression which serves to form a bottom of a trough into which oil leaking from the crankcase seal (pools) collects and drains directly from the transmission side of the gear train housing to the crankcase side of the housing without being further retained via a hole located in said gear train housing between (the bottom of) the crankcase seal and the bottom of the trough and (b) a rim surface for abutting against the transmission side of the gear train housing when said device is mounted to the gear train housing;
- and
- (4) providing a hole in the gear train housing between the bottom of the trough and the bottom of the seal to allow oil to drain from the transmission side of the housing to the crankcase side of the housing.
