    Chevy 14 bolt - gov bomb locker???

    As discussed in another thread i was told there are LSD and something referred to as a governor lock or “gov bomb”. I have had almost nothing to do with diffs in the last 30 years as i just send them away to get built. Even less to do with locking diffs, as i bought one. Then sent it away to...

    Why do Americans hate drain plugs? Drive line oil change queries.

    Yup. Seals, gaskets, hubs, windows, sunroof. Depending on what era car. A mate of mine has a selection of what we both agree are some of the best worst cars. 70s British motors, austins, triumphs, vauxhalls. So bad they are strangely good.

    Why do Americans hate drain plugs? Drive line oil change queries.

    I’m used to dunking my suzuki in water up to its windows. All kitted out for deep water but it still gets in. Regular fluid changes are a must. Latest RockAuto delivery arrived. Transmission filter, air filter, oil filters for future changes. Got the Ram front springs, rear shocks and...

    Why do Americans hate drain plugs? Drive line oil change queries.

    Oils degrade, get contaminated, vehicles get abused. I like to give anything new to me a good service and inspection.

    Why do Americans hate drain plugs? Drive line oil change queries.

    Probably a good job i’m getting 20 litres of Dexron for it. Gonna look at fitting a sump plug while it’s apart but might just get a vacuum extractor. Don’t wanna mess it up and ruin the sump. Probably a lot cleaner to use a vacuum extractor, measure what i take out and refill again to flush...

    New guy with his first square body

    Welcome bud, Very new to squares myself. Bought mine a little over a year ago but due to house moves and workshop building just got around to working on it the last few months. This forum has been a god send. Some very knowledgable folk on it, making some of my jobs a lot easier and quicker.

    Why do Americans hate drain plugs? Drive line oil change queries.

    Does removing the sump drain all the oil from the gearbox or does it have various cavities where the oil sits? It’s down as 9.5lts total but only 2.8lts for a refill on the spec sheet i have. Does using a vacuum extractor get more out? Looking at getting as much oil out as possible as i have...

    Why do Americans hate drain plugs? Drive line oil change queries.

    Not looking forward to the wiring. Loads of plugs and wires that just don’t do anything on this truck. Random plugs just go nowhere.

    NP203 fluid and which driveline oils confirmation

    Without stripping it down is there anyway to tell? I do not know how much of this truck is stock original parts or how much is mix and match from other trucks.

    NP203 fluid and which driveline oils confirmation

    So, as mentioned above I have done various tests. On various posts you guys have confirmed what my drive line is. I’ve done the part time 4WD check, no prop on, in Hi it drives. Had it jacked up and span the rear wheel, both turn in the same direction, LSD fitted. I have been through my...

    Why do Americans hate drain plugs? Drive line oil change queries.

    Until now the only real spannering I have done has been on my Suzuki SJ. Everything has a drain plug. Everything has a fill plug. Dodge ram RWD - take the diff cover off to drain (or suck it out) Is this the correct way to drain the oils from my driveline??? This Chevy TH350 - suck it out...

    NP203 fluid and which driveline oils confirmation

    I have driven it with the front prop off but it may have been in Hi lock as the shifter was vague at best, given it a good clean, degunge, bathed it in WD40 and its a lot more positive. So, basic test with it on stands as the front prop is off. Spinning the rear prop Hi lock (4Hi) - front...

    NP203 fluid and which driveline oils confirmation

    Some absolutely great info chaps. This thing is a whole new ball game to me. Especially as its a mix and match truck, appears to have had mods done to it and has had quite a major rebuild about 16 years ago so I am approaching it with the thought, nothing may be as it seems. I’m on cleaning...

    NP203 fluid and which driveline oils confirmation

    Yeah. Free wheel hubs / locking hubs. I have messaged the previous owner asking if he knows, but all the work he had done was by a garage and they went bust many years ago. Possibly done in America before it was imported to the UK I’ll do some checks on it, although the lever doesn’t have a...

    NP203 fluid and which driveline oils confirmation

    I have read about this conversion but have no idea if it’s been done. It does have FWH fitted but may just have been driven in high lock position. Is there a simple way to identify if the conversion has been done?

    NP203 fluid and which driveline oils confirmation

    Further googling of “identify an NP203” and i think you are correct. There is no 3 bolt idler on mine as fitted to the 205.

    Fuel change over valve Vs twin electric pumps

    This is just a thought at the moment but i suspect my fuel change over valve may be dead, possibly a wiring issue but still to work through it all, its great fun. Has anyone binned off the change over valve and just swapped to switched twin electric pumps? Again, for those who aren’t aware...
