Outer Limits 4x4 Board

Yes, I'm Adam and PTROOL was my project,. No, we are not related. I have not met John, though since I now live in Canberra it would be good to meet the bloke. Thinking about getting myself a Y60 or Y61. My current vehicle just doesnt have the Patrol goodness to it. Got an eye on this: http://www.car...

thanks guys so it seems like I had better get on the phone and ring around - maybe the moon is just at the right phase to find someone to approve it lol

coolant, engine oil, diff oil f and r, transfer oil, transmission oil, brake fluid, clutch fluid if hydrualic. I'd drain the tank and put in new fuel especially if it is diesel. New battery as any SLI battery standing draining like that wont be good. Check to see if you can rotate the engine by hand...

Gday So I have engineering cert for 32.5s on my SFA hilux. My usual engineering signatory seems to be on holiday or something. Has anyone managed to get 35s engineered in NSW? If I can keep the wheel track to spec and just focus in tire diameter? Im running 50mm suspension and 50mm body lift with th...

Mate if I did go gal, is it possible to touch it up if it gets scraped?

Thanks for your comments in this thread youve made some insightful suggestions.

aluminium hex or 50/20 hollow bar won't rust. a few guys use this for links, just tap the ends for fittings david Hex is not the strongest shape, circular is better. I guess it could be argued that rectangular might give a better bearing area for the shock load but thats only the case in an ideal s...

the whole weight argument really goes out the window if your just making some trailing arms and steering links... :roll: if you were building a race buggy or TT i would totally agree and thats why the space frame chassis are made from cromo and links are fabbed from 4340 and heat treated....but the...

Thats good advice thanks. Yeah I plugged some maths and clearly bigger OD is a good step. Im thinking of going to a 50mm OD but need to see if there is any clearance issues with that size.

Its just suspension links and steering links. No section changes, circular. The factory links work for fine dynamic loads in normal situations but they go plastic when shock loaded by being smashed on rocks etcetc. I used to simply sleeve them with 1020 DOM but that wasnt always tough / strong enoug...

I dont understand the logic of your post mate. It seems contrary to proven designs such as 300M DOM tube landing gear in aircraft, 300M DOM tube engine mounts etcetc. You cant compare the strength and toughness of say rockwell 30 heat treated 300M to say annealled 1020. Besides, the supplier has it ...

Stainless steel do not have the strength (tensile, compression shear) and the toughness of other steel alloys. Yes you can make it out of stainless steel but it wont be an optimal design if the builder wants a tough and strong part. Theres other reasons but for the sake of not writing a book those a...

I use a toledo tools one and its been great. McNaught is good but its comparitevly low volume production to the toledo tools grease guns sold globally so the price is higher. Quality wise I cant tell the difference and the toledo has a higher pressure than the kincrome grease gun. I bought some acce...

Your right, thered be many many vehicles out there repaired that way. Most people dont tow heavy objects or hammer their 4wd offroad for years on years. For those that do, even an undamaged chassis can crack and break (this happened to me in my old comp gq). What is certain is that putting tonnes of...

ok so two pack. Which two pack? por 15??

AN steel braided hosing was invented in wartime for a reason

Its not perfectly acceptable. Smashing hydrualic rams onto steel fractures the crystalline structure of the steel, it work hardens, it becomes brittle and will lead to cracking. It might be perfectly acceptable to the laymans eyes but the steel is never the same. Plus some vehicle cant be done this ...

Mate how is por 15 specifically better than powdercoat? Thanks

Thanks folks. Ill prolly go powdercoating.

Stainless steel alloys arent suitable for the tasks I have for a bunch of reasons.

When fitting custom parts to a 4wd whats the best way to protect steel alloys from corrosion? Something that will best endure being scraped on rocks, being caked in mud, having stones thrown at it at highway speeds on dirt roads etcetc e.g. Powercoating Zinc plating Etch primer and paint Galvanising...

Thanks guys Im pleased to get any info on this :) Yeah mate I know what your saying about the brakes and bigger tyres. Its an easy fix for me with a different master cylinder bore size, calipers and rotors on the front. Dunno where Im going to get the rest of the info I need - maybe Ill hassle my lo...

Gday folks Im having trouble finding the specs for my 1987 LN65 dual cab Hilux. I even called the NSW RTA tech line and they dont know. Im currently fully certified with my mods but Im finding the 32.5x11.5R15 tires a bit limiting. Ideally 35s would be great. Q: What is the factory front and rear tr...
