Turnips Posted August 10, 2021 Share Posted August 10, 2021 Feel free to move as I already have the part numbers... I need a replacement diff pan for my 109's Salisbury rear axle, I believe the part number should be RTC844 but when I search this part number online it throws up a diff pan for a 100. Are they one and the same? I also need the support plate which fastens to the bottom of the diff pan as mine is in many shattered pieces. I believe the part number for this is RTC845. I have found this part but it seems very expensive! Does anybody know the function of the part? I presume I am just going to have to bite the bullet here and pay through the nose for one.

Tobias Posted August 10, 2021 Share Posted August 10, 2021 You don't say how expensive expensive is. I have fitted this: https://www.devon4x4.com/diff-cover-d60.html and would do it again. It was available in black when I bought it. Tobias Quote Link to comment Share on other sites More sharing options...
David Sparkes Posted August 10, 2021 Share Posted August 10, 2021 I find several discrepancies relating to your post. Searching for RTC844 bring different results from searching for RTC 844. Generally these refer to a 110 (not a 100). I cannot be 100%, never having played with a 110, but I suspect that for this part 'a Salisbury is a Salisbury' so the wheelbase of the vehicle is immaterial. More were fitted to 110s than 109s, so it's the 110 that gets the mention. Using RTC 844 on ebay I see the cheapest is item number 253671137274 at £55. However, item number 254095288646 at £58 appears to get you a gasket and fill plug, although I'd check before ordering. There is a used version, 224565971333, currently at £30 + £10 postage. For RTC845, that presentation seems more generally recognised (instead of RTC 845) but yes, the price seems high. I guess there is less demand, which begs the question; Do you really need one? I don't have an insight to its function. Regards. Quote Link to comment Share on other sites More sharing options...
Turnips Posted August 11, 2021 Author Share Posted August 11, 2021 Thanks chaps, very helpful. Yeah, '100' was a typo and should have read '110', apologies. A replacement diff pan and stiffening plate still runs to less than the ARB version but thanks @Tobias, they do look nice though! @David Sparkes nobody seems sure what the stiffening plate does, but I am loathed to leave it off and then find out the hard way that it does something to help keep all the oil inside the diff!

western Posted August 11, 2021 Share Posted August 11, 2021 I think the extra plate just beefs up the lower edge of the diff cover to help prevent it getting ripped off, can't see any other reason. Quote Link to comment Share on other sites More sharing options...
