Hi all, changed the oil on my w reg Td5 90 today. When I bought the filter from paddocks I ordered a short filter , when I got it it looked to small I thought, ok my mistake so ordered another filter which was a Bearmac type. So dropped the oil got the old filter off.gggrrrrrr????? eventual . When to put the new filter & I just couldn't get in the right position to screw it on , more ggrrrrr. So checked the length & it was about 10mm ish longer than the one I removed. So at this point the old one was not going back on so I checked out this short one & it flew on . It's about half the length of the old one. DO WE THINK THIS SHORT FILTER OK FOR THE JOB ??? After all it is sold as A TD 5 short filter . Help !!!
