Once you remove the plug, you'll need the adaptor 90513171 and the vacuum hose connector 569714. Both are available (e.g. Craddocks) but quite expensive for what they are. Someone may know what the thread is in the manifold, in which case you may find a simple hose tail adaptor that works. I had...

Steve Parkers do a conversion kit: https://www.steveparkers.com/product/exhs325p-exhaust-system-lr-2-5-petrol-conversion-series-swb/ but you might be able to modify a standard 90 system to fit. I've also read that you can use the 2.5 inlet manifold with the series 2.25 exhaust manifold if you're...

Sam, first thing to check is that the speedo body where the voltage regulator lives is earthed correctly. If the earth is dodgy the regulator can't work properly. If that checks out ok, it'll need some more detective work... There could be an intermittent short to earth on the light green wire...

The info I have (see http://www.starchak.ca/tech/pdfs/lucas.pdf) doesn't have detailed data on Series 3 distributors, but it does have some for Series 2A e.g. model 40944. If you compare the advance curves for 41269 and 40944, it looks like the 41269 has much less advance than the 40944. So I...

Here's how it works: when the wiper switch is ON, power goes from the green wire on the ON side of the wiper switch to the RLG wire that drives the motor. The park switch circuit doesn't do anything while the wiper switch is ON. when the wiper switch is turned OFF, power goes from the green...

I hope that was just an elderly fuse! The diagram is based on info from a really useful Lightweight site http://www.land-rover-lightweight.co.uk/ but re-drawn for a simple SPDT switch. Hopefully self-explanatory, but the only thing to be aware of is that the park switch shorts the NLG wire to...

Well, at least your PO used a relay. My Series LWB had various electrical bodges when I got it, mostly bits of black wire direct from the battery to various switches, plus some tinfoil in the fusebox! I always remove any non-standard wiring to start with, get everything working and then add back...

Your panel lights problem sounds like you have a relay connected into the circuit somewhere, but you'll have to investigate a bit more to know how that has been connected and what it does. Did a PO fit some extra lights maybe? Your research on the Series 3 wiper motor is correct. The input to...

Chris, you might be lucky with a 14mm but it didn't work for me. I eventually gave in and bought a 17/32 socket from Heamar https://www.heamar.co.uk/stahlwille-spanners-sockets-wrenches/48729-bahco-a7400dz-17-32-socket-3-8-aerospace-7314151819866.html Like most bolts, they give up quicker when...

Chris, are you wanting the thread or the spanner size? Assuming the original AM605061 bolts are still there (if the wings have been off in the past, they may be replaced with metric stainless like the ones in rugbynut's link) then the socket size is 17/32 which takes some finding! I don't know...

On the tdi, the solenoid is part of the starter motor itself (it's a pre-engaged starter, not the same as the inertia type on a petrol Series that has a separate solenoid). So you should find a terminal post on the starter with a heavy duty feed from the battery and two brown wires, one goes to...

The Glencoyne 200Di conversion website suggests you connect to the starter solenoid and that's a better option than direct to the battery, which I guess is moved to under the passenger seat in your Landy. You can use a ring terminal on the back of the starter solenoid & make sure it's all clean...

According to Blackburn's diagram, each glowplug draws about 6 Amps, so 24 Amps for all 4. So your 50A cable would be fine. The fuse rating isn't shown on the diagram, but something rated about 40A should be ok to protect the cable and the plugs if there was a short. It might seem like a good...

Didn't make that very clear!:oops: What I mean is that the master cylinder bore is the same for both front and rear ports so the fluid pressure and displacement is going to be the same at both ports. Which makes me wonder why the ports are deliberately different sizes?

The ports on the master cylinder are (usually) different sizes. The rear port (nearest the servo) is 7/16 and the front one is 3/8. They have different colour plastic plugs to alert you to the difference (which you only notice when you have already stripped everything out and have not bought any...

New braided hoses are looking good! Are those the new shocks or the originals? It sounds like you need to adjust the pushrod on the master cylinder. I assume it's the same as the Series 3 i.e. you remove the plate on top of the brake pedal box and adjust to get around 1.5mm free play. You need a...

I'm sure the tdi experts will have all the answers, but a quick look at the Defender parts book shows the glow plugs as ETC8847. They're wired in parallel and powered via the glow plug timer PRC6913. There are some wiring instructions on the Glencoyne website...

I think the Superwinch is the same as the Fairey overdrive? I'm also looking to overhaul my Fairey overdrive and have started to collect the parts needed. With the overdrive out, you need at least the mainshaft gear, the mainshaft bearing housing and the special nut on the back of the mainshaft...

I agree with Tottot that the dampers need checking out - parabolics plus 1-ton shackles is a big lift over standard and they look a bit extended in the pic. Extended bump stops are a good sign that the conversion was done well, plus it looks like you have some kind of extension on the front...

Yes, the 1-ton shocks are longer than the standard ones as the 1-ton has the same extended shackles as the military 109. The part numbers are RTC4231 front and RTC4233 rear. There's info about the the shock dimensions on the Heystee Automotive website as part of their range of parabolic springs...
