To remove filter (jp2m& jk2m engine )remove crankcase door remove nut in the top centre of the scavenge oil pump casing this will allow the filter to be extractedfrom the not lose two small fibre washers on end of the filter which seal inlet connection to the pump.
To remove filter (jp3&jk3m engine )remove crankcase door,unscrew union nut on pipe securing it to the adaptor filter and pipe may be extracted from crankcase
Wash both filters carefully in paraffin and examine fine gauze for perforations renew if holed dry thoroughly. And...
