Dalton1 Posted October 19, 2022 Share Posted October 19, 2022 I need to replace the insulator pads on my 07 CV713 with 46k rears, I was looking at the Atro polyurethane ones but I'm not sure which ones fit my truck, my mack dealer won't give out part numbers. Are the 44k pads the same as the 46k ones?anyone know what the correct part number would be for my truck? Thanks!

Onyx610 Posted October 19, 2022 Share Posted October 19, 2022 I can look up the part number tomorrow for you. If you decide to get the polys you can just go with getting them for the bottom and you can do the rubbers up top if you wanted too. The bottoms are what get all the weight/movement. Make sure you get all new hardware. I’m sure you will but you would be surprised at how many don’t. Also when taking a part make sure the round locating “tit” on the spring “T” is still in good shape. If not the springs are trash. A lot of times they get rusted and worn down to nothing.

Joey Mack Posted October 19, 2022 Share Posted October 19, 2022 Hey Dalton, have you called O'Connor motors ( Formally Maine Mack) at 299 Warren ave. in Portland... I have used many atro kits, but I dont know how the life expectancy compare's to Mack... I think they are close, But they are affordable, and the bolt kit is really good... I have put these in 44 and lighter rears.. jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70590-mack-granite-insulator-pads/#findComment-512975 Share on other sites More sharing options...
Dalton1 Posted October 19, 2022 Author Share Posted October 19, 2022 That would be awesome, thanks! Last 6 is 067250, I can get the whole vin tomorrow if you need it. Was definitely planning on new hardware, nothing comes apart easy on plow trucks, will check those other things as well.

Last 6 is good, oh I know nothing comes apart easy on anything in the North East. I live it just like you do! Get a needle scaler to knock all that shit out of the inside of those buckets and make sure you lube the new pads with a non petroleum lube. We use Goop waterless hand soap. 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70590-mack-granite-insulator-pads/#findComment-512977 Share on other sites More sharing options...
Dalton1 Posted October 19, 2022 Author Share Posted October 19, 2022 I have tried to get part #s in the past from O'Conner and McDivitt in Manchester (whos since sold off there Mack side)but neither liked to give out part numbers. Maybe I'm just not getting the right parts guy. I was under the impression the Atros would out last the OE ones but I'd be interested to hear what you guys recommend, looking to get whatever works best and last the longest.

Joey Mack Posted October 19, 2022 Share Posted October 19, 2022 Onyx has access to vin. lookup, I was just suggesting if you call them they might give you the part number, or sell the Atro kit at a price you like... 800-464-6225 jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70590-mack-granite-insulator-pads/#findComment-512979 Share on other sites More sharing options...

Onyx610 Posted October 19, 2022 Share Posted October 19, 2022 The polys will last the longest. I’ve never used them before. I’m not sure the price difference though.

Joey Mack Posted October 19, 2022 Share Posted October 19, 2022 https://www.autoandtrucksprings.com/mack-insulator-mp-end-pads/..... you may find what you need here... the product is ATS... I have seen them in trucks before, I think they compare to ATRO... Hopefully someone who has used them can give you a good answer about durability.. jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70590-mack-granite-insulator-pads/#findComment-512984 Share on other sites More sharing options...

Onyx610 Posted October 19, 2022 Share Posted October 19, 2022 (edited) Don’t use the MK when searching also the meritor part number is from the “R” over. Mack uses meritor anyway. But that whole number is a Mack number for YOUR truck.

Dalton1 Posted October 19, 2022 Author Share Posted October 19, 2022 Awesome thank you, should be able to get the ones I need now. Looks like there the same as a 44k but still double checking that.

Onyx610 Posted October 19, 2022 Share Posted October 19, 2022 That I can’t answer, I wouldn’t think there would be a difference. If any they would be bigger and you might have an issue. Guys like Joey and mark t could pry answer that.

Dalton1 Posted October 19, 2022 Author Share Posted October 19, 2022 (edited) Looks like the Atro kit SK62-50340 has the correct pads for my truck and probably all the other plow guys that run a former New York DOT CV713 Edited October 19, 2022 by Dalton1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70590-mack-granite-insulator-pads/#findComment-512993 Share on other sites More sharing options...

Dalton1 Posted October 19, 2022 Author Share Posted October 19, 2022 My last one the inner frame rusted all the way through, been using wool wax coating on this one regularly, seems to make a big difference.

Popular Post Mark T Posted October 19, 2022 Popular Post Share Posted October 19, 2022 Gotta watch the holes in the spring like Onyx said. They can be way bigger than the dowel on the new pad if the spring is shot . The buckets too, if they're rotted enough on the inside and enough metal is missing they won't squish anything like it needs to be. Most of the better pads are colored or clear, and the top ones may be black . Tops don't get the pound'n like the bottom ones. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/70590-mack-granite-insulator-pads/#findComment-513004 Share on other sites More sharing options...
