Hydraulic oil filter - 85 UrQ

[alanpem@wimsey.com (Alan Pemberton)]

The hydraulic oil filter in the hydraulic reservoir in later year UrQs is a 
different design to earlier models.  The earlier version filtered the return 
fluid from the power steering through a paper cartridge filter.  If this 
blocked, flow was diverted through a band filter.  The 85 UrQ has no paper 
filter - just the band filter which is retained by a top cover plate under 
spring tension.

Having drained the hydraulic reservoir to change the hydraulic pump, I decided 
to check the filter.  It is a fibrous material and was obviously blocked with 
a deposit that looked like coagulated oil.  The backpressure had caused the 
filter element to swell outwards.

A new element is going in when the part arrives.  Suggest next time anyone is 
working on the hydraulic system, that the filter be checked.
