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.

cheers for that,

yeh searching cam gears or timing belt etc etc in here and trying to find exactly what your after, is like searching for a needle in a haystack

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

    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
