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.

Have you disconnected the QR1 valve before the maxibrakes to see if the line feeding it gets air when you push the tractor parking valve? If it doesn't, trace the line back from there, maybe a section of the line is crushed or collapsed on the inside. Hopefully someone didn't work on the truck before and hook something up wrong.

The ad says this truck was built in 1996 as a glider but it's never been titled or used so it's basically a new truck. I'm scratching my head wondering why someone would keep a glider kit around for 28 years. That V12 would be a beast of a motor, you'd have to mortgage your house to keep it in fuel and parts. https://www.ebay.com/itm/226520381739

That flatbed has a little curve to it!

That's the oil filter. I pulled the cover off mine and it has a pleated paper element inside (Wix 51954). The cover gasket is like $50 so I just reused my old gasket.

That looks to be a small cam Cummins, my 335 doesn't have an aftercooler so that may be what you have. I used to work on big cam 290's back in the 80s, did they make a small cam 290?

Bruce Wilson looks at a custom H67 on an Iveco chassis, with Dodge fenders. Interesting looking truck, looks like high quality work. Also a nice IH and Pete in the video.
