When I had the same problem couldn’t find the bolt. Ended up buying the complete part

Many thanks for your updates, I went the replacement pipe in the end as its my daily driver and cant afford for it being off the road for long,
will investigate with some of the turbo company's to see if its viable to just get the bolt as a separate item through them. |

I couldn't find a supplier for just the banjo bolt so will have to use the land rover part LR031928
Couple of questions though, When fitting the new banjo bolt should I try the land rover torque setting again of 35nm or 25 ft/lb or use less? Also does it matter if the two feed hole's in the banjo bolt don't perfectly line up with the two holes in the oil feed union? |

Why would you not use the LR torque figure? Do you have reason to suspect that it is wrong or excessive?
The alignment is irrelevant, the banjo union will have a circumferential gallery machined within it (besides it would be virtually impossible to fit the banjo and bolt in a particular alignment). |

The reason I asked about the torque figure is the last one snapped before the 35nm figure stated in my
W S Manual, Thanks for the confirmation on the second question, thought that was the case but it always good to have someone else confirm. |

Aha, so you have a very good reason for not using the LR figure, and I suspect that you have answered your own question!
Unfortunately I don't know the size of the banjo bolt in question (and I am not going to take mine out to find out, I'm afraid) but recommended torques are available online, for example: https://www.hoseandfittings.com/banjo-torque/ I suggest measuring the bolt and making an appropriate judgement. The link above recommends 18Nm for a 1/8" BSPP bolt with copper washers (remember that BSPP threads are based on the bore size of a pipe not the OD, so 1/8"BSPP is actually 9.7mm outside diameter by 28tpi, which is about what my memory tells me for the bolt in question), so 35Nm does sound rather high. I freely admit that I come from the old school of spannering and don't follow torque settings for non-critical parts with the kind of slavish devotion that youngsters do, and if I was fitting the bolt I would not use a torque wrench at all, I'd just do it up until it felt right. It doesn't have to be wildly tight, just tight enough not to leak and not ti unscrew itself. I appreciate that this isn't much help to the inexperienced though. |

Not at all Blackwolf, always happy to learn from anyone who has more knowledge and experience than myself.

Hi,
a few months ago I swapped the turbo in my Puma 2.4 and made a picture of the Banjo-Bolt:  Click image to enlarge It is a M10x1.25 bolt, you´ll need two new copper-gaskets. The smaller one needs an inner diameter of ~10.2 mm, the larger one needs ~13.2 mm, both have a thickness between 1.5 and 2 mm. Of course, there is no part number for the copper gaskets, so I took some no name gaskets, works fine so far. The Banjo-Bolt is tightened with 35 Nm and new seals. Greetings,  Defender 110 TD5

^^ I wonder how the threads on the bolt in the picture became so damaged?
35Nm is approx 26 lbft, and I have found a reference to a Kawasaki spec for a stainless banjo bolt of the same thread and pitch used on a braking system where a torque of 19 - 23 lbft is specified. A stainless banjo seems usually to be about 5% tighter than a steel banjo, so 26 lbft is rather higher but is not wildly different. By this metric, 15 - 20 lbft would probably be appropriate. The LR WSM, especially for the TDCi, is generously filled with typos, errors, and random nonsense so it is usually wise to sanity-check torque figures (the manual in several places quotes even different figures for the same fasteners). I suppose that as far as the 35Nm question is concerned we are now in Clint Eastwood territory - "do you feel lucky?" |

Fitted the new banjo bolt, torqued it down to 20ft/lb and left it at that no leaks and new turbo works fine.
once the rain stops will take it for a test drive but all seems ok so far after running it for 15 minutes. Thanks everyone for there comments, |
