Brilliant write up, my Discovery had exactly this problem of the throttle spindle seal leaking, without instructions would have been totally lost. Took the throttle spindle housing into my local Bosch dealer Diesco of Ipswich and they were extremely helpful and had all the parts in stock, they did show a little surprise that I had taken it to bits and said they didn’t recommend it, they also gave me the impression that they did not think I would be able to get it running properly again. Any way glad to report that following instructions to the letter it started straight away after priming it with the cut of wire detached and it runs a dream with no diesel leaks and no need of any further adjustments, just to make sure of the measurements of the adjusting screws before I dismantled not only did I measure them with venire gauge but backed this up by taking close up photos of them which enabled me to count the number of threads protruding. The part numbers I was supplied were Spindle bush 1460324333 spindle O ring 1460210008 Throttle cover gasket 1461015302 all purchased for the sum of £10.14. Thanks so much for taking the time to write such a good article.
