jacobs retarder

[Jeff Miller]

Regarding the posts on the Jacobs EL retarder ('83-'86 WLFC):

All that I have owned had one grease fitting, facing the retarder from
the front of the coach you should find it in a recess in the outer
frame at about the 4:30 position (lower streetside corner of the outer
frame), usually buried in grease/dirt.

We have found a weephole in the opposite corner of the frame,
apparently to relieve excess or old grease when lubricating the
retarder, which can be impacted with hardened grease/dirt.

The gentleman who has a buildup of grease in the retarder should IMO
clean it out, the retarder can get quite hot and I don't believe that
the presence of grease in the retarder is good. It is likely that this
buildup is due to a plugged/impacted vent hole is forcing grease past
the seals.

Be sure to use the proper high-heat grease.
