Hi, It is an 1980 320 Coolpower. Any colour is fine. These are certainly hard to come by!

Hi all, Looking for a cover for my Evans Tempcon Heater. I have attached a picture showing an example of what I am after. Even one in poor condition as I am in the process of restoring my Mack. Thanks!

Hi all, Have just put an 18spd Eaton into an R Model Mack but now need to hook up speedo. It has 4 wires coming from gearbox and is magnetic inside. It has three wires coming from the engine bay. We have another Mack that has a gear driven speedo. Any advice is welcome!

Thanks for all the responses. Will put it in the shop. Called up a few places to ask advice and more than likely the govenor is worn as per previous responses n here. Will let you know the results!

Just saying...pour it in a pan and i might cook my steak in it looks that clean. Everyone always says the oil goes black straight away after you put it in. Maybe they are just making the poster feel better about their dirty oil

Another thing it starts first time every time. Only started about 4 times a year in the past 3 years and before that sat around. And it doesn't do it all the time. Hasn't burnt any oil as the oil is still clean after 3 years...with a few trips on the road but mostly sitting around. Does that sound like something is wrong with either the pump or head?

Thanks everyone. Hopefully it isn't the pump. If we find the solution I will post it up. If anyone else has any ideas don't be afraid to post! Thanks again!

gearhead204 please see my previous post. It has video of the truck on you-tube. This is my original description - Seems to pulse on idle (sometimes it is fine though) and really pulses when you just touch the accelerator as you can hear in the YouTube clip. You really need to put your foot down but when you change to the next gear it does the same until you really put your foot down. http://www.bigmacktrucks.com/index.php?/topic/34007-r-model-320-coolpower-hard-to-drive-pulsing-r612rst/

Any help as to where it is located would be fantastic

Hi all, Finally getting around to try to stop the roll in my 1982 R Model 350 E6 engine. Have been trying to find a pic of where the buffer screw is located. Is it the screw in the pic on the rear side of the injection pump? Thanks in advance!

Come on everyone!! Just worried that something is wrong in the fuel pump. Any ideas would be most appreciated!!

Hi all, If you could please check out the link to my YouTube clip. http://www.youtube.com/watch?v=O6tLOXM4DBA Does it sound like it is running OK. Seems to pulse on idle (sometimes it is fine though) and really pulses when you just touch the accelerator as you can hear in the YouTube clip. You really need to put your foot down but when you change to the next gear it does the same until you really put your foot down. May be just how the truck is...our 350 R688RST is completely different. Any advice would be much appreciated! Thanks Steve

Hi, OK now it has 354 welded on the housing. But I have always had in my mind that they are 5.17 in there. I will have to go to the yard and check. Thanks for the info Gear Ratio Eighth H 0.73 Eighth L 0.86 Seventh H 1.00 Seventh L 1.17 Sixth H 1.38 Sixth L 1.62 Fifth H 1.95 Fifth L 2.29 Fourth H 2.73 Fourth L 3.20 Third H 3.74 Third L 4.38 Second H 5.16 Second L 6.05 First H 7.30 First L 8.56 Lo H 12.29 Lo L 14.40

Hi all, I have a 320 Cool power R-model. At the moment it has a two stick 5 speed transmission but I think the 2nd stick is just for lo-lo. And drives very slow...but has 354 welded on the diff housing. I have the chance to grab a Eaton 18spd double overdrive from a 1994 International Transtar. Will this make my truck faster and more for highway travel? I am just waiting on the model number of the box. Have read that double overdrives went out in the 80s but yet have had plenty of people tell me they are the go. Thanks for any info

Hi all, Why would diesel be spraying out of the Air Start baffle on startup on my r600?? Thanks
