Removing a head on a detroit diesel 671

This is a fun one, getting the 4 valve head upgrade. Detroit diesel 671 cylinder head removal. Gm bus vintage rv bus conversion

[@xposeireland]

Hi Steve . My name is Albert and I am from Ennis Ireland .I am also a Bus mechanic and a HGV Mechanic. I realy enjoy the videos that you up load and you give alot of great advice. I have to say one thing and that is That you could save alot of time using Air tools or electric to speed things up. Some of the videos scared the living Shite out of me because my friend got killed when a jack failed. Sorry to say it but your Bus proping seems very hairy to me .my nerves are SHOT. Just go the extra mile on safety for your family. Thank you for the vids ALBERT PRICE.

Nice to watch someone wrench the way I learned and prefer today - no pneumatic tools- no cordless - just a man a ratchet and the magic of leverage.

[@ROTAXD]

WESTY70 the idea behind pneumatic & cordless tools is to work smarter, not harder.

[@Westy73]

ROTAXD sure. Any first year apprentice can make that comment/observation but what I’m getting at is the Zen of knowing a machine backwards and forwards - this is a tactile knowledge.

[@ROTAXD]

WESTY70 been wrenching for nearly 30 years and guess what, if there’s a way to save time and or effort, I’m going to choose to save said time or effort. Not that I’m implying head bolts or lower rod cap bolts should be run in with an impact.

[@Westy73]

ROTAXD that is a valid point if you do this professionally I presume . I’ve also got 30 + years messing with cars but I don’t do it for a living so I’m not too concerned about saving a few minutes here and there. It’s something that I enjoy which is altogether different and goes back to my initial comments.

[@GlennsSpeedShop]

Scott... love your channel! I am a licensed Electrician with 37 years IBEW, have been an avid RV.er forever, have set up a couple off grid solar cabins, and we just bought a 1963 4106! About your inverter issue... Here is my opinion and suggestion from what I got of your video yesterday.... Remember only when you are using shore power is your Bus actually grounded, while on gen or inverter, it's floating... in your sub panel you are correct, do not bond the Neutral and grounds together. I suggest you idintify the 120 volt circuit or circuits in your sub panel you wish to have on your inverter. From what I remember, one or two circuits can flow through the inverter when it is not on, then when it is on it will power them? I don't have the book, but I thought that was how you explained it. My bus has a 7000 watt Gen but only a 30 amp shore power cord that they just plugged into it... With 58 amps available, I am suprised it has not burned up..lol... I am ordering a transfer switch for it and a 50 amp shore power cord and will upgrade my main electrical and video for my KZbin channel. Fire back if you have questions, would gladly help you through it. May need a return favor some day! Cheers... Glenn

My brother & I are both "ambidextrous" when it comes to metric & imperial nuts but at the time his lads weren't.... I came back from a tea run (we are British....) and his lads are frantically digging through tool cases looking for a "Ten-eights" wrench and can't find one. Needless to say it only took me seconds to find the right one. I think their education was less incomplete by the end of the day.

A gear wrench set and 3/8 Milwaukee M12 stubby impact and M12 ratchet would save you so much time, they fit everywhere the big impacts and ratchets won't

[@billmcintyre2995]

Totally agree, ratchet wrenches are huge time savers. They are the first set of tools I grab when working on anything mechanical. Also what you said about a pair of M12 (or the new brushless 20V like my buddy just got, would love a set but my old M12's still work too well to justify replacement) tools would have made this go so much faster.

[@Ridinfixinman]

I agree - my stuff is snappy 14v but is sized similar to the Milwaukee tools and I find myself using them pretty much ALL the time. They're just so fast, especially the cordless ratchet in tight areas.

[@Spyke383]

We have them, we just dont always use them. We take our time and have fun when we are working on our stuff together.

Every m12 tool I've bought has been great. 1/4 impact, hammerdrill/drill, driver, hackzall, and circular saw. 3 batteries and 2 chargers will get you through most FML situations.

As I got older, I got a lot lazier. Now I use a small battery powered impact for disassembly stuff. A lot faster!

[@gullreefclub]

Pass on battery powered impacts and nut runners they are expensive and have a short service life. Air tools now that’s different story, good ones lasts for decades if oiled and can be run in the middle of nowhere using a CO2 or Nitrogen bottle setup. If you go to auctions often time a bottles and regulators can be purchased pretty cheaply.

[@ROTAXD]

gullreefclub actually, the use of air tool is steeply on the decline. As for running them on a bottle of nitrogen, unless you want to be carrying a 120 cu.ft. Cylinder around with you, they’re pretty worthless. With the brushless motors & lithium packs in quality modern cordless tools and the availability of aftermarket replacement batteries...cordless is the way to go. I with the exception of my needle scaler I rarely use my pneumatic tools nowadays.

Your buddy doesnt think gear wrench are good tools? I say they are exelent. A bit square and sharp on edges. And sometimes too big to fit box end on. But exelent quality. I can't say i watched most of your video. But it did help me to get head off my 4-71. Had all bolts out. But wasnt sure about amount of force needed to remove it. Didn't want to break anything. Also all the years of using electrical tape i never thought of the tab thing to remove it. Which is quite odd. I do that with rolls of packing and masking tape so i can find end next time i use it. Lol then i resort to fighting elec tape when removing it. Anyway , thanks for the video.

To bad you can't figure out a way to shoe-horn an air-to-air inter-cooler in front of your radiator. You know , have one built, or find one that will be a close fit. Shoving hot boosted air into a super charger, boosting it and heating it some more, then feeding it to the cylinders, I cringe a little. Diesels run so much better with inter-cooling. But i get it, they ran them that way, and it worked. I've run Lucas for years in my diesel engines, but I will have to look into that slippery stuff you guys were talking about, saw you adding it a few videos back.

You are too busy now with the head but when you do get back to the inverter. I installed a Xantrex 3k pure and I made a sub box. I used pop up breakers, 4 circuits using a plastic junction box to house the breakers and related wires. Only drawback is the pop up breakers can not be switched off but if I kill the feed to the inverter with the inverter turned off than the circuits are off. My reason was space but it was also a little cheaper getting the breakers on ebay. I have used it for 4 years now with no problems full time living. One of the circuits feeds my convection oven and another the kitchen outlets , once I had the kitchen pop due to too many appliances plugged in. Easy to make your own bus in the plastic box and not have to modify to isolate the bus bars if you need to especially if you are only having two circuits just use split bolts.
