Just wondering here... what was the normal running oil temp of the old E6 engines? all the R models I drove never had a oil temp gauge. The 3406E and C15 that I ran would match the water temp for the most part. I hear some say oil temp should stay at or slightly above 212 to boil any condensation out of the oil. rarely did my 3406 run higher oil temp than 210.

Dan said the same thing. I was not aware the CH cab had 2 different cab depths like the R model did. I never really followed the CH model thru the years. That is odd that they went with the short BBC cab when a deeper CH cab would offer more space for day cab. Heck if a Bench seat was offered a few more inches is always needed for the guy having to ride in the middle. and that shiftier sticking out of the dash is horrible. no reason it could not be put on the dash with push buttons like the new trucks have. I have never understood the short BBC that todays mfg strive for. Id rather have more leg room and have to move the seat a notch or 2 forward than to drive a cramped cab with the seat banging against the rear wall. The truck looks promising and has potential if volvo dont fuck it up like they did with the titan. yes late to the game (as always) but I do think it has a shot if it proves reliable.

Just saw this post. (been busy with kids!!!) Amazing work once again! love the detail you put into these trucks. are you still making model parts kits for the RS700. I recently knocked the dust off my old RS700L and started to get it ready for the road again. Its been about 6 years the last time I went to a Truck show with it.

that 3 leaf suspension was for on road use. the springs were known to brake in the off road. they also would brake the shock mounts due to excessive travel. will it work for you. im sure it will.. is it set up right for a dump truck. not really. price should be the deciding factor here in my opinion. that being said a exporter would pay about that much for it.

lots of B models were upgraded to 237 or 285. if it has 2 spin on filters thats a good clue but could also have been converted. do you have a pic of the engine? any part numbers on the turbo or injection pump that you could use to cross reference?

Thanks to everyone for the help with this. I also need to give thanks to Josh Yoos as he explained how he converted many of his trucks to Air ride cab. For those who are looking to do this conversion here is what worked for me. I unbolted the old solid mount hood rests from the fire wall and replaced with R model hood Roller brackets that bolted right up to the same location on the firewall. I then installed these parts on the Hood. they were direct bolt on after the old solid mount pads were removed. Hood Roller #55MX26 Hood Bracket #140QM213 Hood plate #140QM212

Im not very current on all of the offerings at mack (volvo) but a ratio of 2.47 is way to fast for logging. This sales man sounds like he was selling you a truck he had in stock and needed to move or was just clueless on how to spec a truck for on/off road use. And please take no offense but you should have noticed that highway spec gearing on the agreed build sheet. Im shocked the salesman had the balls to sell you on that.. the M drive has a 14.94 first gear compare that to the old 2 stick 6 speed that has a 14.10 first gear in Lo-Lo with the popular 4.17 rear gear ratio . These new salesmen seam dead set at selling fuel saving packages. they push this new Low RPM on road spec to everyone. Many of these guys dont understand the need for stability in the off road at max weight limits. the 3.25 will be better but I agree with KT that its still a fast gear for the off road but the M drive may make use of it? I know if it was manual trans it would be hard on the clutch if staring out in soft sand. the locking rear diff is a nice addition to a truck used in the off road. I thought macks auto power divider was the best until I drove a truck with the locking rear option. the truck I drive now has power divider lock and rear rear diff lock. thing can drive thru anything as long as my front axle dont sink in. it amazed me how much better a truck was with the diff lock option

Great looking older Mack... dont see to many of these...

I just had a issue where my Dash courtesy toggle (top of dash LH side) was killing my marker lights. replaced the switch all good now. this was on my 77'

got a assembly on Ebay tonight. need to source one more.. i also got set up on pai... great to see so many aftermarket parts available since Volvo is of little help these days

ill try that tonight. thank you

yep i ordered new rollers last week and fitted them yesterday hopeful it would fix the hood rest issues but I suspect i need that channel attached to the plate. previously that plate had a large rubber puck bolted to it. i removed the puck thinking the new rollers would make contact on the plate but they dont.

(driverside) I have the plate that bolts to the hood but not that channel. where can i find a current Pai catalog. i thought i need to be a distributor to access their online parts. thats what i was told years ago. thank you

i drove my RS700 for one season in Chicago with no Power steering.. no fun so I put a power steering unit off a Valueliner. best thing i did to the truck.

there was a guy in Florida making stainless steel covers. both eastern and western. i forget who it was but he was always bringing them to the mack show out in PA

my 77 RS700L vin is RS786 32474 LST. I think western RS700 series production ended in 78' when the superliner was introduced?

yep looking for the old style. thank you for those numbers

im looking for the screw on connectors as that's what my harness is right now. thank you all for those part numbers.. Trent.

Years ago I put a superliner cab air suspension on my truck. during the upgrade i also put R model hood rollers on the cowl. the issue is the driver side of the hood does not make contact with the roller. I raised the rollers 1/2", moved them forward but its still resting the cowl. im wondering if i am missing a part? anyone have a pic of a western mack with the hood / roller assembly? Thank you

still having issues...i installed these gauges in 2012 but never got the right sensing units. mack had sold me one back in 2012 but it was reading incorrect. i just ordered a new sending unit ( part number above) and hope to have it in the oil pan next week to test it.

Yes When I wiggle the toggle I can get the 2 out side clearance lights and fender lights to come on. but as soon as I hit a bump they go out. The center 3 markers headlights tail lights all stay on with no issues. its 100% in the switch but I think its original to the truck. I searched online for the number but could not find it. Mack is almost useless with these old dogs. the numbers are there in the system but the new guys behind the counter have to dig deep to find the numbers. if you find a number I will use it and call mack to see if they have any in stock. it should be a common issue in the old truck world. and still a handfull of R models out there working

volmack number 25006165

64MT146 was the sending unit number for reference

I talked with a friend tonight about doing just that. a fresh weld of the holes and sanding of the whole panel to remove some of the road scars. its going to be covered with paint so really just need to clean up the area around the holes so It dont look so banged up.

Yes I recall you had them. They did look good. I might just and find some aluminum plate with the similar stock pattern and cut them out. They will be painted flat black just like what I have now.
