0 mowerman Posted February 26 Share Posted February 26 But yes, it sounds like you have the same problem as I do around here thank God I got just about everything I need now and collecting parts for this thing for the past 30 years all I really need is 10 new tires, and a bunch of hoses and lines Quote Link to comment https://www.bigmacktrucks.com/topic/73910-rd-specs/page/2/#findComment-547231 Share on other sites More sharing options...
0 Macktruckman Posted February 26 Author Share Posted February 26 Thats good to know bob thats what im looking for too honest experience. I believe for sure while i had the engine out making the swap id send the pump to the pump shop and have it gone through and set max. And i have a new turbo for an E6-350 that id use. Might help it. But all that is second choice as im actively hunting a deal on a mechanical or vmac E7 as my first choice for a new engine josh 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73910-rd-specs/page/2/#findComment-547232 Share on other sites More sharing options...
0 mowerman Posted February 26 Share Posted February 26 1 hour ago, Macktruckman said: Yeah I understand the parts thing bob that’s why I’m so interested in this parts truck. Where I live theres no old macks around and zero older Macks in the only salvage close. I bought that hood from a place up north and paid as much freight as I paid for the hood. So i get it. This parts truck has a 300 4 valve. I’ve never driven it. I only have experience in tbe 2 valve engines josh I got real lucky when I first moved to Reno. There was a wrecking yard really close and it had 3F model Mack’s from UPS I was able to get two perfect doors and one fuel tank but now that wrecking yard has since closed 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73910-rd-specs/page/2/#findComment-547233 Share on other sites More sharing options...

0 mowerman Posted February 26 Share Posted February 26 Yes, one of the fellas out here turned me onto double coins. They’re about the cheapest around. I’m finding them online for under $100. I know the Michelin tires we use at work are around $500 apiece just for a recreational vehicle. No I’m not gonna spend that much. I railer look around for used which is still very rare in this area size.1000-20 tube type but they still use them on container chassis Quote Link to comment https://www.bigmacktrucks.com/topic/73910-rd-specs/page/2/#findComment-547235 Share on other sites More sharing options...
0 mowerman Posted February 26 Share Posted February 26 This is the worst one. I don’t think it would make it very far but I did drive a truck home 35 miles when I first bought it the tires were a little better shape.

0 67RModel Posted February 26 Share Posted February 26 A 690S is Vocational spec with the Maxidyne version of the E6/E7. It will be either 250, 275, or 300 horsepower Maxidyne. And generally have a 6,7, or 8 speed vocational transmission, which is basically just a regular 5 speed with either 1, 2, or 3 off road creeper gears. Paired with really deep rears. All three of those transmissions have the 0.6:1 overdrive in them so there is that really annoying gap between 4th (direct) and 5th gear. 4th gear your maxed out at 40/45 mph and 5th gear it takes off like a rocket ship and has poor gradeability. They are actually a great setup for certain types of work and terrain. I imagine in Oklahoma where its all flat would be a great set up. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/73910-rd-specs/page/2/#findComment-547238 Share on other sites More sharing options...

0 Macktruckman Posted February 26 Author Share Posted February 26 Well… there lies the kicker. Lol. In far eastern Oklahoma where we are its hill after hill and winding roads so no good run at your hill. Not much flat where I live. Lol. That truck was originally a EM6-250L. Has a sister truck specs identical I believe. They said the trucks were gutless and they took them to a mack dealer in okc and had them “turned up” they came back running much better im told and mack dealer restamped the engine tag “300” this particular truck the mechanic here tells me ran better than any of the macks on the place. I believe the pump is ambac where mine is robert bosch. My truck had the 107 2 stick 6 speed and I liked it well on site and flat ground (except for no overdrive). I put a RTO-14909MLL in its place a few years ago and it definitely helped with the hills. And with the 4.17 rears the overdrive is nice on the highway. And still have deep reduction gears for site work. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73910-rd-specs/page/2/#findComment-547240 Share on other sites More sharing options...
0 mowerman Posted February 26 Share Posted February 26 I was going to say that I also ran the 6 speed 2 stick 237. I hated that thing and yes the biggest problem they are flat ground trucks. Are perfect for City work. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73910-rd-specs/page/2/#findComment-547242 Share on other sites More sharing options...

0 Macktruckman Posted February 26 Author Share Posted February 26 Oh yeah bob i loved that 6 speed for real local and site work. Gravel pits. When build pads and use a borrow pit on the same property. Things like that. But it needs a gear between 4 & 5 in the man box and then a decent overdrive (like eatons .73) after 5th. It screamed to do 55 on the highway and it fell on its face if it even saw a hill coming.

0 mowerman Posted February 26 Share Posted February 26 Yes sir I know all about it small grade you gotta lug it down to 35 before you can drop a gear. It seems like it takes forever and yes I used to go up a grapevine loaded down doubles 40,000 pounds and around 12 miles an hour. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73910-rd-specs/page/2/#findComment-547246 Share on other sites More sharing options...

I don't remember if they were 5 or 6 spoke hubs but what I can see of your axle looks like the common 8 bolt used on 38's the heavier axle I've seen used 6 bolt or the cone shaped axles
