Loadstar Posted September 25, 2012 Share Posted September 25, 2012 Well, pulled the manifolds today......exhaust one has a couple hair line cracks.....and where the intake and exhaust bolt together someone over tightened the bolts and cracked the bolt flanges......going to take it to a machine shop on Thursday if I do not get any responses to my post in the parts section.....Let the games begin!!!! It would have to be welded and re-surfaced where they meet. Couldn't see the crack until it came off......Thanks....Louie Quote Link to comment https://www.bigmacktrucks.com/topic/27510-manifold-issues/ Share on other sites More sharing options...
fxfymn Posted September 26, 2012 Share Posted September 26, 2012 Louie,I assume they are cast iron??? If so they cannot be welded using ordinary methods and you will need to find someone who knows how to work on cast iron. If you cannot find someone locally to do the repairs let me know. I can hook you up with someone in PA that can do it. 1 Quote Money, sex, and fire; everybody thinks everyone else is getting more than they are!

yarnall Posted October 15, 2012 Share Posted October 15, 2012 Contact Cal Little at Pine Hill Trailer Sales in Hummelstown Pa. He has 707 parts for sale. He will want your old manifold to repair.Mike 1 Quote Link to comment https://www.bigmacktrucks.com/topic/27510-manifold-issues/#findComment-141747 Share on other sites More sharing options...
Loadstar Posted October 15, 2012 Author Share Posted October 15, 2012 Thanks mike, I have called a bunch of people.... He was one of them.....said when he got around to it he would look? Hopefully it's soon.... The truck is in a friends shop.... Pretty much taking up the whole garage.Thanks again Quote Link to comment https://www.bigmacktrucks.com/topic/27510-manifold-issues/#findComment-141764 Share on other sites More sharing options...
fxfymn Posted October 15, 2012 Share Posted October 15, 2012 Louie,Cal Little is who I would recommend. He has someone that is an absolute magician with cast iron. A friend took a manifold from a 25 AB to him that was in pieces; it came back looking factory fresh in a couple of months.Your best bet with Cal is to go there personally. He may be at the Trucktoberfest, and if not it is not too far from Allentown to his place. 1 Quote Money, sex, and fire; everybody thinks everyone else is getting more than they are!

paulromano Posted October 15, 2012 Share Posted October 15, 2012 Cal is defintely a great resource. If you don't have success, you could call Chuck Buschardt in Houston, TX, a retired Houston FF who is a Mack Fan and has quite a bit of stuff (pieces/parts) when I was last there. 832-724-7968. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/27510-manifold-issues/#findComment-141832 Share on other sites More sharing options...

Loadstar Posted November 16, 2012 Author Share Posted November 16, 2012 Well finally got the manifolds all set to go back on......repaired and re-machined....ended up getting a used set that wasnt cracked.....but when i split the intake and exhaust manifolds apart there was hole in the intake similar to the original set.....must be a common problem....anyway fixed the original intake and plan on using the new/used exhaust.....

fxfymn Posted November 20, 2012 Share Posted November 20, 2012 Albert,Are you looking for the entire set up (stanchions and rails) or just the replacement rails?Carl Quote Money, sex, and fire; everybody thinks everyone else is getting more than they are!

rsb502 Posted November 20, 2012 Share Posted November 20, 2012 did you get the exhaust back on yet? if not VHT makes a spray on coating that is a baked on ceramic spray coat it works great keeping the exhaust looking new if you get it in Cast Iron color I have a couple cans here on hand just in case.

609albert Posted November 21, 2012 Share Posted November 21, 2012 carl ,looking for the center stanions, and end pieces that would be on a 50's era mack, I could get them rechromed if needed, and then get a set of rails from clothing racks,I think you said they are the same dia. thanks ,AL Quote Link to comment https://www.bigmacktrucks.com/topic/27510-manifold-issues/#findComment-147187 Share on other sites More sharing options...
fxfymn Posted November 21, 2012 Share Posted November 21, 2012 Al,I know where a set was/is??? I'll have to check the next time I'm in the area. Could be a while.Do you want the two hole or three hole style?Have you checked with Cal Little yet?Try posting what you need here. I know of at least one poster, who I cannot recall, that had a junk LS85 with the stanchions still on it.There is also a vendor on EBay that is advertising a Mack booster reel who claims he is parting out several Mack fire trucks. http://www.ebay.com/itm/1950s-Mack-fire-truck-hose-real-PARTING-OUT-300-CLASSIC-CARS-hot-rat-rod-/110964347117?hash=item19d5fd90ed&item=110964347117&pt=Vintage_Car_Truck_Parts_Accessories&vxp=mtrCarl Quote Money, sex, and fire; everybody thinks everyone else is getting more than they are!

Loadstar Posted December 29, 2012 Author Share Posted December 29, 2012 No, I didn't paint them......I used some sort of graphite paste.......a friend of mine used it on his "69" Z28.......I'm sure it will wear off but it looks decent now and can be Put on easy enough. The stuff 84superdog recommended would have been better but I just wanted them back on the truck.
