2014 Defender 110 Puma 2.2 SW Santorini Black

Help Late Puma Owners - Turbocharger Actuator.

Hi All,

I’ve just been forced to change the turbo on my 2014 110, root cause has been resolved. I received a recon turbo, all looked good until I came to refit.

The actuator gearbox now fowls the air con compressor. Turbo supplier are helpful, but insist there are no part differences and don’t understand why it won’t fit.

Would anyone but kind enough to confirm the part number if you can, on their actuator gearbox, and post a few photos of your turbo, on a late Puma?

Really feeling like in going mad..

Thanks
Andy

I recently replaced the actuator on my 2013 2.2 to solve a problem with sticking vanes. Yon can read all about it here, in case it helps:

I can tell you that the correct actuator should be stamped G-72:

Thanks Darren

One other question, could you possibly confirm the part number on the compressor housing?

My original had the number JKM2, the replacement JKM1. I wondering if the location of the mounting for the actuator is different to clear the aircon compressor?

No, I'm afraid not. I didn't remove the shield to expose it, I'm afraid.

Scratch that - I've just realised that the number you're talking about is just visible in my picture of the bare actuator. It's not a brilliant angle to be honest, but it looks to be JKM1:

Fixed

I did.

Turns out the exhaust housing is specific to the late Puma; dealer / supplier struggled. I had the existing turbo rebuilt.

2010 Defender 110 Puma 2.4 HT Alaska White

Related to turbo actuator part numbers, I am fairly sure I need to replace the actuator on my 2010 2.4tdci.

Symptoms: limp mode when I drive over 60mph for about 5mins or more, reset by cycling the ignition. No engine lights nor error codes. I can move the turbo vanes with the actuator disconnected and it moves freely (hot and cold). Checked the wiring and all seems to be okay. When I start and rev the engine, the actuator does not move the vanes at all.

The part numbers on the actuator currently fitted are 752406, 009206, and G-48. But I'm seeing a lot of G-34 actuators online and I'm not sure what the difference is. The Defender is on 160k miles so the turbo may not be original.

Any thoughts on what the G number refers to, and which is required? I am wondering whether the current actuator is right which could be the root cause.

Make sure the pivots on the EA actuator bar are kept periodically lubed with light oil from a dripper.
Don’t grease them unless it’s the LR dedicated ceramic grease which costs a fortune!

3 in 1 light oil sorted mine out, it’s been good ever since but they do get sticky, that I turn affects the actuation of the EA and operation of the tube vanes, will also induce a small amount of lag too. NEVER SURRENDER! ⛽️🛢️👨‍🔧🧰⚙️ RED, WHITE & BOOST! 🇬🇧

Gents

can anyone tell the position of the turbo actuator lever/link (up or down) BOTH at idle and with the engine off? I am chasing a smoke problem on a 2.4 model.

Thx

2.4 Turbo

I hope I am lucky this time and I get a word of advice.

Should the turbo vanes moves aboslutely freely?

After I removed the "circlip" from the actuator lever I found out the internals were stuck and I could not move the lever whatsoever. After I few taps into he lever it was free. However, I still feel a bit of friction by moving up and down the lever. Puma 110" SW

I found that the best way to describe it is to say it should feel as though the linkage has broken and isn't actually doing anything in the turbo. It is surprising how freely it moves if it is working correctly.
