You will need to remove:

radiator

fan and belts

cam angle sensor

top timing cover

crank pulley and then

lower timing cover

timing belt

Its best to get the timing marks all lined up before you take the timing belt off, so then you can just 'one for one' each cam gear without changing any of the marks. Then its just a reverse process to put it all back together.

There should already be a bit of info on this, just search. Also the manual sets it out fairly straight forward.

Yeah all of that except the fan and radiator.

That's what I was going to say!

Do the water pump, belt, idler and tensioner bearings, front seal, cam seals and the bolt and stud....unless you just did a major service less than 20,000km ago!

you might get away with the radiator in but fan definately has to come out. and if your balancer hasnt been off in a while and you need to use a puller than the radiator will probs have to come out.

Mine was uber tight and ended up needing a massive claw puller to get it off, but because the puller was so long, I had to remove the A/C condenser as well HAHA!

You can just swap the gears over with the front cover off, without removing the timing belt completely. Have the engine at tdc and swap one at a time, they are a bit tight to get on and off, but definatly heaps less stuffing about.

If your worried about the balancer tdc mark being correct, only a matter of checking no1 piston tdc through the spark plug hole.

Yeh I think the cam gears can wait for another 30000kms or so (My car only has 55000kms on it)

Are you sure they are legit? :D

Cam gears for their price as one of the best mods you can do really.

Certainly no harm in doing a big service like that early, lots of people do it around 80,000 - some just do it soon as it comes off the boat :)

if u can remove a harmonic balancer without removing fan and radiator i really want to know how :D :D

Why do you want to remove the harmonic balancer to replace the cam gears?

He said gears and that was all he asked about. Other stuff is a different story and yes fan & radiator out but if he only wants the cam gears done he doesnt need to dismantle half the engine.

I've done it that way on an RB25DET - not too hard.

If you want to go the whole hog here is a tutorial:

I am very surprised to find this method is possible, i've been delaying doing the job as have recently done a 100k service but didn't think to put cam gears in (doh!)

Also I agree with the comment above about the belt tension.. off tension the belt is still a biarch to get on.. hmm

Yeh they are met I have the full history of the car, the previous owner used it as a weekend only car racking up about 7000kms in 5 years with full service history

Ok ye cool - fair enough to wait, although depends how many km's you do in a year, you might be waiting a while :D

      New fix for low tyre pressure from bmw

      I believe Unimog is the only vehicle that has it (from the manufacturer). I haven't seen aftermarket permanently connected kits, but I haven't looked either.

      Ha ha ha, can't overthink when exhausted... Oh how I wish I had that power! I can be absolutely dead set shot, and my brain will still go "we need a good 3 or 4 hours to just think about everything and anything before you may sleep... My biggest thing is making sure I give myself enough sleep. I don't operate on even 7 hours of sleep! I attempt to give my body 9.5hours sleep a night to be able to function. I don't sleep the whole 9.5, but I need to make sure I offer a big window. I also take a single supplement, which is to help with long term health, and fighting inflammation, and I notice it helps massively. Especially me sleeping, and just less "achey" in the body. Have also kicked sugar, and gluten. A majority of people with ADHD don't go well with gluten. It causes a really interesting natural opioid overdose in the brain, which causes bodily issues and sensory issues.

      Yep. But typically that's just run a hose down to the tyre while stationary.   Oh and the Unimog will automatically air up and air down tyres from the onboard computer for you too.

      There was a good video somewhere, maybe Kurzgesagt that linked physical activity to ADHD/Anxiety/Insomnia etc. Basically the body WILL spend energy doing something if you don't spend it doing anything physical. It isn't fun, but I personally have noticed I've never been overthinky, or unable to sleep if I'm physically exhausted from doing a lot. The musings around it seem to indicate that this is one of the reasons/mechanism that physical activity improves mental health/wellbeing etc, by more or less not using that 'extra' energy to overthink, be anxious, inflammation, etc. There's also the fact that every obnoxious exerciser ever says it's great and helps which is extremely annoying. Like people who say the same thing about travel being the best thing ever. I mean, they clearly are, but blah. I started doing a LITTLE myself (think 3x15min per week) and honestly did notice the benefits, aiming at life quality when older. Which is sooner than you think. Getting something into your routine that you can actually make a routine has helped me at least. This post brought to you by procrastination between sets.
