I remember the old timers used to use vinegar to remove rust in the cooling system, but I don't know the ratio to use with water.

Those have to be painted steel, I've never seen an aluminum Dayton rim.

I figured I could probably replace the spring but the valve/seat is worn so I went ahead and replaced it.

I’ve been fighting a starting issue since I got this truck back together in 2023, of course I only drive it about 6 times a year so I haven’t pushed too hard to fix it. It would start easily but then run out of fuel and I would have to crank it for a few seconds to get it going again. Also the hand primer wouldn’t pick up fuel unless I poured fuel in the inlet line. I went through the fuel lines, check valves, and replaced the hand primer. Then a couple of weeks ago I was reading what other guys did to fix theirs, and one guy on here (now I can’t find the post) said the overflow valve would cause this problem. That is the return tee at the back of the injection pump. I never had any experience with those; I looked at my old fuel system repair manual and it said that valve could cause issues with starting and low power. The spec on mine is 15 psi; I tested it and it held less than 10 psi. The one for the 673 is 697GC15, but that is NLA. The number for the E6 is 697GC123 and it’s the same configuration (1/4 x 1/4 x 1/8 NPT) so I bought one from PAI (no. 801090, $100). I tested the new one and it holds 20 psi. I installed it and now the truck starts and runs correctly. It’s frustrating to dink around with something for so long but I’m glad it’s fixed!

Looks like you have a lot of work to do but keep with it and it will be a nice truck.

My H67 doesn't have any tranny mounts, that's the factory setup.

I think he added one too many zeroes. I wonder if the ratchet strap holding the sleeper on comes with it? https://www.facebook.com/marketplace/item/1136868254904067/?ref=search&referral_code=null&referral_story_type=post&tracking=browse_serp%3A02a9e9c5-94cf-4f72-93c8-be0ad566562b

Found this pic on the interweb, would they use this in truck driver school? 😉

How did you get the hood to fit the cowl? I thought the Super cab was different.

Found on Facebook--$500 and not very rusty. https://www.facebook.com/marketplace/item/613283311500355/?ref=browse_tab&referral_code=marketplace_general&referral_story_type=general&tracking={"qid"%3A"-250280660094383479"%2C"mf_story_key"%3A"6145237117257297340"%2C"top_level_post_id"%3A"6145237117257297340"%2C"commerce_rank_obj"%3A"{\"target_id\"%3A6145237117257297340%2C\"target_type\"%3A6%2C\"primary_position\"%3A8%2C\"ranking_signature\"%3A4992237805707172412%2C\"commerce_channel\"%3A501%2C\"value\"%3A0.00043171385602967%2C\"upsell_type\"%3A3523%2C\"candidate_retrieval_source_map\"%3A{\"25297733569912644\"%3A3528%2C\"9523595094365609\"%3A3001%2C\"23983949287860260\"%3A3528%2C\"8490111297741128\"%3A3001%2C\"9557736740954907\"%3A3565}%2C\"grouping_info\"%3Anull}"%2C"lightning_feed_qid"%3A"-250285332916101524"%2C"lightning_feed_ranking_signature"%3A"4992237805707172412"}

Everyone who looks at these says there's no equivalent size, you have to buy 12:00x24. https://budgettrucktires.com/products/12-00r24-bridgestone-g-580-super-drive-all-position-tt?variant=45357800980634&country=US&currency=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gad_source=1&gclid=EAIaIQobChMIqc2C9bfSiwMV3EL_AR0mtwYUEAQYASABEgLTLfD_BwE

With that boiler inside the cab, you'd stay nice and toasty in the winter!

Yes they'll fit. The flange is 20" ID so it fits the old 20" hubs. I have 22.5s on some of my old 20" trucks.

That thing looks awfully crusty for $8k, but if someone really wanted an integral sleeper then it may be worth it.

Is it for your personal shop, or a business? Glad to see progress being made.

Air cleaner in the cab...geez! I'll bet that thing was noisy inside...driver comfort not important.

There's one on ebay for $18 from Arkansas Valley Diesel (their customer service is a little spotty, so hopefully no trouble getting the switch). https://www.ebay.com/itm/156308028277?_skw=cole+55071+switch&itmmeta=01JJ5201GZ2WZ44X84GZ1YC356&hash=item2464af3b75:g:z1oAAOSwWi9hRQP0&itmprp=enc%3AAQAJAAAA8HoV3kP08IDx%2BKZ9MfhVJKlAl%2By20gw3p%2BH6DLgI93FaVwVagQQ9Joh%2BsYhsMJuSmVCPayt8ZinO1Wx9o4ZuZhzjbXVAiaNfJYfzKtjM0mC4%2BCDSSRzbKMALUyX52FN1TjMvE4ydtu65%2F1S9ZY%2FxUIzvbEmSPQsLMxDdz6wGDQwnMVL1uQYSi9W%2BMf2jLzv4VbvIBp3QjGf4P304FCPqDi%2Fa0FVkQj%2FbmeRTDAmRjtaSi%2FWw6vUIRy8BxnRVuNQeaImwXQY92SnB1Fu9o9gHFY0i4VSG%2Bdu0xVG8PnhCTn88Dh3foNmH6CqdLaLmY9HMTw%3D%3D|tkp%3ABk9SR9SYgKKRZQ

These old lowboys are cool, would look great with an old Mack. https://www.facebook.com/marketplace/item/971502761539079/?ref=browse_tab&referral_code=marketplace_general&referral_story_type=general&tracking={"qid"%3A"-534556301541365454"%2C"mf_story_key"%3A"2671790806830394380"%2C"top_level_post_id"%3A"2671790806830394380"%2C"commerce_rank_obj"%3A"{\"target_id\"%3A2671790806830394380%2C\"target_type\"%3A6%2C\"primary_position\"%3A27%2C\"ranking_signature\"%3A4665422969087303694%2C\"commerce_channel\"%3A501%2C\"value\"%3A0.00024119002070637%2C\"upsell_type\"%3A129%2C\"candidate_retrieval_source_map\"%3A{\"9702054749822850\"%3A3560%2C\"7640627662685074\"%3A3565%2C\"7194035650648533\"%3A3547%2C\"9004153099702847\"%3A3122%2C\"9365340240176577\"%3A3021%2C\"8709322179176445\"%3A3122}%2C\"grouping_info\"%3Anull}"%2C"lightning_feed_qid"%3A"-534580215996137943"%2C"lightning_feed_ranking_signature"%3A"2079728984510381187"}

That's a great chart, very handy to have around!

Looks great! It's cool that you have those as a memory of your father.

Looks like someone did a lot of work to this truck, but...um... https://www.facebook.com/marketplace/item/575686515349364/?ref=browse_tab&referral_code=marketplace_top_picks&referral_story_type=top_picks

Cool to see those old Macks working! The video takes place in Jamaica, my wife and I went to St. Lucia a few years ago and they have some crazy roads like that and even crazier drivers.

That's a beautiful truck, I like the red and gold paint. They did a fantastic job on the restoration...I can tell you mine won't turn out that nice. Those V12 Detroits are unlike any other truck engine.
