Do these really fit an LC? Landie stuff is Imperial and an LC isn't lol. But if they do does anyone know the part number or have an eBay link?
Cheers, Alex

They fit but the connector is different. I found an equivalent sender with a male spade connector...let me try to find the thread...

I fitted one, then made a fly lead to connect the spade of the loom to the round pin of the sender.
Been reliable for several years.

our bikes are a plumbing thread, a tapering BSP in the later models and a straight thread in LC.
FWIW tapered 1/8 (i think) BSP was very common in the 80s... so much so that my cheapo halfords generic tap n die set from back then has a tap for it.

Are these probes colour coded? Green for the LC?

If you are not wearing a green anorak, then you can use the Landrover ones with an adapter or modify the connector on your loom.

I seem to have misplaced my anorak! Landie it is. Thanks again mate.

Pretty certain mine was a diesel landy fitment.

Its a long time since I looked out that tap... |

Seems likely considering the rest of the bike is metric. |

BA threads are metric though.

Why not M10? Seems likely considering the rest of the bike is metric. What's the bore on your master cylinder? 15.875mm, but point taken. There are lots of legacy imperial measurements on metric bikes and cars. I was just wondering why Steve said that it was definitely a imperial thread. Do LC's and YPVS's use the same sensor/thread? I ask because I have 2 YPVS heads (marked Y1 and Y2) which both definitely have M10x1 threads. They both have what look to be the original temperature senders, blade terminal, marked NS (Nippon Seiki?), with parallel threads and a sealing washer. From what I've heard later YPVS heads (Y3 - F2?) have a 1/8NPT thread sender and presumably a matching thread in the head. Which makes sense, 1/8NPT is a really common sensor size for OEM and aftermarket. Probably because it is relatively easy to adapt to other sizes. It's also possible to force a 1/8NPT sensor into a M10x1 hole because the thread pitches are so similar (1/8NPT is 27tpi = 0.94mm), |

I was going on what my local engineer had said
Also the assumption that they were both 1/8 thread, just one was parallel and one was tapered
You are correct that Y1 and Y2 heads used the straight thread and Y3 was NPT
Suppose the only way to know for sure is to check an early sensor with a thread pitch gauge as I think the actual threads are different shapes never mind 27 tpi against 25.4 tpi

Yep, with a thread gauge the early sensor (Y1 and Y2, 31k YPVS head) has a M10 parallel thread, with 1mm pitch (which is 25.4 tpi I suppose).
I've confirmed this by winding a M10x1 bolt into the head(s) where it fits perfectly (a Shimano bicycle derailleur bolt).
1/8 NPT is 27 tpi tapered, no match
1/8 NPS, the straight/parallel version of the NP thread is also 27 tpi and doesn't match.
1/8 BSP is 28 tpi, no match, miles out.
I'm interested in this because I have a Y3 head that has had an obviously incorrect threaded sensor forced into it, butchering the thread. I'm trying to work out what it should be and how to fix it. From what you've said it should be 1/8NPT, thanks. It looks like if there is not enough material left to tap it out NPT, I might be able to put a M10 thread in it.

Drill it oversize, tap it and make up a threaded brass bush, with a thread of your choice on the inside.

Post by crogthomas on Mar 13, 2023 11:16:27 GMT 1
Yep, I'll do that if there is not enough to tap it as it is.
