I had a Badger incident. The splitter brought the brunt of the exchange and needed replacing.
Get underneath the splitter ( take an old pillow/ head rest and head torch) and locate the spiggots, i used a pair of plyers to manipulate the spiggots staight while my mate pulled from the front. Came of easily enough.--------------However,,
Fitting a new one was a complete SOD. Lots of sweating and swearing and the two parts finally went on.
My tip-- deep breathing and be patient. Oh yeah, drink lots of tea.
