Lmackattack Posted January 20, 2020 Share Posted January 20, 2020 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?

seyser Posted January 20, 2020 Share Posted January 20, 2020 They must have used different setups over the years. My 79 R has flat metal plates on the cab side and round rubber hockey pucks on the hood side.

I believe that is a non air ride set up, the poster has a air ride cab, has a roller to move with the cab. terry Quote Link to comment https://www.bigmacktrucks.com/topic/60639-mack-western-hood-rollers-air-ride-cab/#findComment-440958 Share on other sites More sharing options...
seyser Posted January 20, 2020 Share Posted January 20, 2020 Ah yes, that makes sense. I was always curious why the different setups. Didn’t event think about the cab being hinged and constantly moving.

Rob Posted January 20, 2020 Share Posted January 20, 2020 I don't have a photo Trent but the pads that mount on the underside of the hood are different for the rollers to bear against with air ride.

Quickfarms Posted January 21, 2020 Share Posted January 21, 2020 This is two pieces the first piece bolts to the hood through the center of the bracket you have, I think the bolt is 3/8" fine tread, then the channel shaped piece attaches to it with two screws and nuts The parts are NLA trough Mack but it looks like PAI now has them 1 Quote Link to comment https://www.bigmacktrucks.com/topic/60639-mack-western-hood-rollers-air-ride-cab/#findComment-441015 Share on other sites More sharing options...

Make shore the rivets are good and use the correct ones if you have to replace them.

kscarbel2 Posted January 21, 2020 Share Posted January 21, 2020 The gray rollers pictured on the cab firewall are part number 55MX26. I can't recall the part number of the roller track that mounts on the hood, but most likely a 73RU number.

Lmackattack Posted January 21, 2020 Author Share Posted January 21, 2020 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.

Lmackattack Posted January 31, 2020 Author Share Posted January 31, 2020 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 Quote Link to comment https://www.bigmacktrucks.com/topic/60639-mack-western-hood-rollers-air-ride-cab/#findComment-441640 Share on other sites More sharing options...
PMC Posted January 9 Share Posted January 9 (edited) Working on a Superliner 1 and converting the hood over to rollers but having a little difficult getting things to line up. Using salvaged parts the hood seems to sit about half an inch high where the hood meets the cowl. Are there different height hood brackets?

PMC Posted March 10 Share Posted March 10 (edited) That’s a good idea, looks like they could be turned down to work. I did the opposite and made thinner brackets that mount on the hood. Seems to work ok. thanks pmc Edited March 13 by PMC 2 Quote Link to comment https://www.bigmacktrucks.com/topic/60639-mack-western-hood-rollers-air-ride-cab/#findComment-547912 Share on other sites More sharing options...
