ok, havent updated in ages so ill cut and paste here what ive done -
Wyatt from RST and Demello Offroad and Marlin Czajkowski from Marlin Crawler came down to Melbourne Australia in March to fit one of these into my hilux -
the new design 4.7 crawlbox into my 07 hilux.
just before they came i fitted some extra rubber sidemount flares to my hilux to help cover the tyres -
These I'll mount to the side of the firbeglass flares and will cover my tyre completely (current fibreglass flares dont cover the sidewall only the tread) and will match the width of the mudflaps that I have fabricated. And will be more legal.
These are the ones below....
A few days before the Yanks came over i removed the tailshafts and got them ready for the install.I had the front tail shaft extended 8.5" and the front portion of the rear shaft shortened 8.5".
Heres a pic of those side mount rubber flares fitted -
Ive also slapped on some Marlin stickers to help promote their product......
Marlin and Wyatt and me began this project late sunday night, was supposed to be started monday but Marlin wanted a quick look below the transfercase shift lever boot through the cut out of the floor just to ensure everything was ok......first problem!
We found that the hilux has a forward shifting transfercase rather than a top shifting one like the Tacoma's and FJ cruisers do.....How does this make it a problem?
Let me explain further.....
A forward shift for those that may not know is when the actual shifter itself is located ontop of the adaptor plate between the rear of the transmission and the front of the factory transfercase.......the transfercase has extra long shift rods to accomadate the extra distance needed to shift gears.
This is a problem because we are required to remove this factory adaptor plate from the back of the transmission and fit the marlin Crawler one.
Other problem we encountered straight away was the fact that even thou every technical journal and resource we used to work out what transfercase it was and what gearbox the hilux had, once everything was apart we realised that the adaptor plates were incorrect.....for some reason Toyota used different adaptor plates/bel/housings on the hilux where they would have used a different one again for the US market even thou the transmission and gearbox itself were the same.
So halfway through Monday we weren't looking good.
Marlin contacted his workshop in the USA and organise to get the correct adaptor plates sent down for the Crawler Box, aswell as a short shift kit for the factory j-pattern transfercase as the location it would come up would be behind the auto shifter between it and the lid of the center console. Space is a premium here so we needed everything we could use to help.
Heres is some pics.
First one below is view from underneath with everything pretty much gutted!
Next pic is view on interior thats been gutted too! :shock:
Pic below is of the factory transfercase and the crawl box beside it with both the front and rear adaptor plates removed, which is why it looks so narrow......if you have a look at the front of the factory transfercase you can see the shift rods exit the front of it - this is where our problem lies......the extra length of those rods goes into the rear of the auto transmission adaptor plate to the transfer.....in this adaptor plate there is an opening on top just like the one you can see ontop of the factory transfercase where the transfer shifter fits in the standard configuration......the opening in the pic below you see is because we removed a blank cover that was fitted there.
Seems toyota uses the same transfercase in multiple market but this configuration is only for the hilux's......same transfercase in tacoma and FJ but they have their TOP shifted whereas the hilux is FRONT shifted......
A front shift configuration you see in applications where the vehicle has a front bench seat fitted and they move the shifter forward for more room.....looks like they have done this in this case and just carried it through across the range.
Last pic, I have just sat the extra shifter behind the auto selector so you can see where it will exit the transmission tunnel......we will be flipping the auto shift cable bracket you see there to make more room for a drilling a hole through the tranny tunnel......in this position is where the factory shifter will be located but we will be using a short shift design as space is at a premium here.
Late Monday afternoon, we went to a Toyota Wrecker to see what sort of transfercases they had here....if they had a "left hand dropped with a top shifter" we would have bought it and replaced it with mine......
Problem again is that no such beast exists here in Australia at all.
We found a couple right hand dropped transfercases with a top shifter but no left hand ones........The idea behind this is that we would purchase these if we had too and use the shift rods out of them.
Tuesday, we went to ARB headquarters here in Kilsyth for a tour of the factory and facilities with the guys.....absolutely awesome......I was speechless......you really get a great appreciation for the quality of a product when you actually see how its built and put together.....the ARB air locker was an impressive unit to see being built....I have pics but havent uploaded them yet to the PC, will do that later on at some stage.
On the way home from ARB, we swung past the wreckers again and we purchased a transfercase out of a 2003 Hilux 3.4 V6.......for 300bux.
We also found from other older toyota transfercases factory made short shifter's, shifter lever and the base and it was a perfect fit........so we took that aswell.
Got home, and we all got stuck into the job.
What an honour it is to see someone like Marlin himself stripping apart a transfercase literally with his eyes blindfolded and explaining exactly the process of it and what each little component does along the way - mate! did I learn abit watching him.
We pulled the shift rods out of the 2003 Hilux's tranfercase since they are shorter because of the top shift configuration and we then stripped my transfercase and removed the longer shift rods from the forward-shift design and slapped the shorter ones into it and then put it all back together.
By the end of last night, I was the proud owner, quite possibly of the only "Left Hand Dropped, Top 'Quick Shifter(Short Throw)' 05+ Hilux Chain Driven Tranfercase" in the world!!!!!!!!!
So we are looking good now.
We can still use the incorrect Marlin Crawler adaptor plates to mount everything up for measurements sake, and work on the new location of the factory J-Shifter Transfercase lever, extend the wiring of the sensors/pickups on the transfercase by 8.5" and ensure the tailshafts have been resized the right amount.
Then when the adaptor plates arrive from the US on thrusday, we just replace them and we are good to go!
