beatngu Posted November 12, 2016 Share Posted November 12, 2016 Well I ran into another silly roadblock. My heads have these brass inserts to center them on the deck, one head was lacking them and it needs the special washers for the larger corner studs. Would anybody happen to know where to get these? I tried searching the forum but turned up nothing. Good news, plowing OT is on the way and I have a stack on the old girl now.

Call Parts Dept. they are open Saturday 6 a.m. to Noon. Phone # 1-888-304-6225. They can help. There is Jobbersinc.com phone # 215-236-8500 they know the 673 engines also. Oldmacks.com Dennis has a wealth of knowledge about these engines also. Some of these guys on this site may chime in and give you some leads to.

beatngu Posted November 12, 2016 Author Share Posted November 12, 2016 One thing to do tomorrow is pulling a head off my 711 to see if it has those brass pieces, and if watts doesn't have those washers I will have them made. These were things I hoped to find second hand as jobbers is far from budget friendly.

beatngu Posted November 12, 2016 Author Share Posted November 12, 2016 Well looks like gettingbthembout of the 711 without ruining them is out if the question. Is there a proper name for them?

41chevy Posted November 13, 2016 Share Posted November 13, 2016 I don't know if Watts has the washers but I do know they are hardened steel. The cylinder head locating dowels are easily made from brass rod on a lathe if all else fails.Mike up the diameter. You may even be able to find them the correct diameter and only need to cut the length. Paul.

terry Posted November 13, 2016 Share Posted November 13, 2016 i always thought the dowels were steel, would't brass ones deform if you dropped head on a little hard? terry 1 Quote Link to comment https://www.bigmacktrucks.com/topic/47659-673-centering-dowels/#findComment-351763 Share on other sites More sharing options...

It is 65% copper,35% zinc and is a hard, high tensile alloy used for screws, rivet, dowel pins and springs.

beatngu Posted November 16, 2016 Author Share Posted November 16, 2016 it's the small details that make you feel the dumbest. The other head does not need the dowels because there are holes drilled in the head for the dowels in the deck. My good buddy is going to fabricate some reducing washers for me problem solved!

The OEM washers are hardened steel, Might be best to use 4130 Moly steel.

beatngu Posted November 20, 2016 Author Share Posted November 20, 2016 for future reference when I called Watts I was told if it isn't on the website (for B model) they don't have it. Jobbers looked but I assume they didn't find anything for dowels or special washers.

41chevy Posted November 20, 2016 Share Posted November 20, 2016 Here's a link also Manley and ARP make Hardened Head Bolt washers ( a speed shop would have them most likely) and probably the ID /OD you need.

JerryBeck Posted December 6, 2016 Share Posted December 6, 2016 Guys I've always found B model head bolt washers and that type parts at Fastenal, Motion Industries, or similar supply companies. Moseley machine shop in Houston probably has any insert you might need. Gary was rebuilding Mack heads when Hitler was a corporal. I found it was way easier to go get new head nuts and washers than have to pull the oil pan to fetch the originals back.

beatngu Posted December 11, 2016 Author Share Posted December 11, 2016 My new bushing washers are getting cut tomorrow I am thinking 3 inches should be long enough with a quarter inch on top for a washer Quote Link to comment https://www.bigmacktrucks.com/topic/47659-673-centering-dowels/#findComment-354673 Share on other sites More sharing options...
39 Baby Mack Posted December 11, 2016 Share Posted December 11, 2016 They don't need to be long, the original ones weren't. 1/4" would be a fine length for the part that goes down in the head too!

beatngu Posted December 16, 2016 Author Share Posted December 16, 2016 I guess the foot length of 4130 was a tad overkill then! I could have a few more cut if anybody needs them. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/47659-673-centering-dowels/#findComment-355261 Share on other sites More sharing options...
