Chris Davies Posted September 21, 2015 Share Posted September 21, 2015 Hi, I'm replacing the swivel bolts as part of my front axle refurb. The parts book state 1 of ftc3454 (Dowel bolt) and 6 of ftc3456 (bolt swivel housing). Looking at the ones that came out I can't see any obvious difference. I would just order what it suggests but I like to get my bits from LRdirect at the moment because they offer a choice of makes and they don't list ftc3454. Anyone know what the dowel bolt ftc3454 is/does Cheers Chris Quote Link to comment Share on other sites More sharing options...
David Sparkes Posted September 21, 2015 Share Posted September 21, 2015 Craddocks translate FTC3454 to UYG 500040 Follow the link and you will see the description references the standard bolt as UYG 500050. These numbers may help you find stock with your favoured supplier. Re your general question; a dowel bolt is one where the unthreaded shank is slightly larger in diameter than the same area on a standard bolt. The reason is to make it a snug fit in the swivel, the snug fit inhibits the swivel from moving under load. It should be understood that such movement can, over time, loosen the fixings. Not everyone bothers with the dowel bolts, as you have found. Your choice. HTH. Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted September 21, 2015 Share Posted September 21, 2015 Otherwise known as a fitted bolt, if you dont use it, you'll never get the castor angle correct.... Quote Link to comment Share on other sites More sharing options...
Chris Davies Posted September 21, 2015 Author Share Posted September 21, 2015 OK, thanks for the reply's, will have a closer look armed with a digital caliper. Also LRdirect list uyg500040 so thanks for that link also. Cheers Chris Quote Link to comment Share on other sites More sharing options...
landroversforever Posted September 21, 2015 Share Posted September 21, 2015 Do the later axles have a location for the head of the shoulder bolt then?! My '84 certainly doesn't so there's no location for it. Quote Link to comment Share on other sites More sharing options...
Chris Davies Posted September 21, 2015 Author Share Posted September 21, 2015 Not sure what you mean Ross, the earlier axles/swivels do use a dowel bolt according to the parts book. Its not obvious which hole you put them in though, will have a closer look later. Chris Quote Link to comment Share on other sites More sharing options...
landroversforever Posted September 21, 2015 Share Posted September 21, 2015 Normally any kind of locating bolt like that would have a counter bore in the hole to locate in, you wouldn't bother locating on just the thread if that makes sense? I only put the normal bolt ones in when I rebuilt my front axle last time, and I'll probably do the same this time as well. Quote Link to comment Share on other sites More sharing options...
Maverik Posted September 21, 2015 Share Posted September 21, 2015 I've always used uyg500050, which I think are exactly the same... Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted September 21, 2015 Share Posted September 21, 2015 Does the shoulder not sit within the hole on the swivel ball flange? Then the thread goes into the axle and positively locates it. I'd have thought you'd need two to make it fixed, but perhaps I'm missing the theory.

landroversforever Posted September 21, 2015 Share Posted September 21, 2015 You wouldn't normally use a thread to locate something. You only need one as the step on the back of he ball locates the ball, the bolt locates it axially. Quote Link to comment Share on other sites More sharing options...
Scotts90 Posted September 21, 2015 Share Posted September 21, 2015 I've never seen/noticed a different bolt on the swivels I've replaced on both early and late axles. Could be someone prior has replaced all bolts but I agree with James/Mav and Ross, can't see how the swivel could rotate on its axis and affect castor as all the holes are a tight fit.

dailysleaze Posted September 21, 2015 Share Posted September 21, 2015 I ordered 1 and 6 of the two part numbers. The bolts that came were identical. (and they were genuine) Quote Link to comment Share on other sites More sharing options...
Scotts90 Posted September 21, 2015 Share Posted September 21, 2015 My old 86 bolts were all the same, no dowel types. Quote Link to comment Share on other sites More sharing options...
Chris Davies Posted October 2, 2015 Author Share Posted October 2, 2015 Thought I would update this thread, I ordered 2 of one and 12 of the other and as others have said, they all look identical. Cheers Chris Quote Link to comment Share on other sites More sharing options...
David Sparkes Posted October 3, 2015 Share Posted October 3, 2015 As a matter of curiosity, did the different types come in different sealed bags, each with a suppliers printed label, which will have different part numbers as part of the label? I have found in the past, from a seller who offers the options of 'genuine' or 'pattern', that the parts come in separate bags, but of their choosing, and either unlabelled or with a handwritten number on the bag itself. With small items, like bolts, that are supplied by Land Rover in packs of 5 or 10, unless you order a 'pack' you never see the LR labelling. I have also suspected that having ordered 'genuine' I've been supplied with pattern parts, either by a mistake in the picking, or because the 'genuine' were out of stock. Naturally (to a cynical mind) there is no mention of any deliberate substitution, or a refund. Once or twice I've ordered the same part in both styles, just to judge the difference. Sometimes it's obvious, even when the packets are unlabelled, but this self-checking can turn out to be an expensive pastime. Bottom line, I'm inclined to believe it's a Genuine Land Rover part if it comes in a sealed Land Rover bag or box, with printed labelling to match. If it just says 'genuine' on the invoice or packing list, or in the advert or web site description, my inclination to believe is less strong. Perhaps others have more faith, or more luck, with their suppliers :-) Regards. Quote Link to comment Share on other sites More sharing options...
Chris Davies Posted October 3, 2015 Author Share Posted October 3, 2015 These came in separate bags with hand written part numbers. The 2 'different' ones ftc3454 or UYG500040 were ordered as Land Rover parts, the others were only available from Bearmach so anyone's guess.
