In reply to a message from Weston Keyes sent Wed 4 Nov 2015:
I believe there are three failures of the Rolon part
documented on this web sit in the last 18 months to two
years. I advised all of the major suppliers of this about
a year ago when I was looking for a Reynold style part.
That Rolon junk should be removed from inventories.
I and others believe the underlying issue is that the
conical filter in the supply line is typically removed when
the Rolon casting is bolted to the block. A small speck of
dirt lodged over the pinhole opening in the side of the
cylinder casting will shut down all oil flow to the
cylinder…as well as the thru hole in the rubber slipper.
Pathetic design. I used the plunger/shoe assembly from
a ‘‘Jaguar style’’ tensioner unit from SNG in conjunction
with an original Jaguar cylinder casting. Important to
keep that conical screen in the oil gallery. The ‘‘Jaguar
style’’ cylinder casting does not include the cylindrical
reducer pip between the oil gallery and the tensioner
body. That little transfer reducer holds the conical screen in the gallery. This makes the casting portion of the ‘‘Jaguar style’’
screen in the gallery. This makes the casting portion of
the ‘‘Jaguar style’’ unit worthless. Bad situation.
Surprised the Reynold unit is available from Rover. Good
tip.–
