39 Baby Mack

Wish you all the best, have a good day!! Ron

If you say so!!Ron

Kent Looks like a new one ! Ron

N&W #1218 was a class A 2-6-6-4 locomotive, N&W Y class locomotives were 2-8-8-2's Ron

Southern Pacific GS-4 Northern's and AC Cab Forwards and quite a few other steam locomotives had both steam whistles and air horns on them! Ron

Yea it will fit but if you leave off the bracket you will lose the famous "knife edge door seal" that the Mack Co. was so proud of!!! Ron

If the extra piece on the bottom of the door for the door seal is good on one of your driver's doors you could get one of the doors off of Mike and weld that piece on an "R" model door and you you should be good to go. Ron

Vinny Go to a good glass shop in your area and show them what you need, they should be able to help you out. It won't be the whole gasket like the one you have now, it will be in a strip or roll, and you'll have to get the locking rubber separately. When you install it just make sure to put the seam on the bottom. Ron

That's wat it is!! Ron

This is a longshot, but the reason I asked about the notches in the gasket was that at one time there was a special head gasket made to salvage old blocks that could not be resurfaced unless cutting beyond minimum dimension from top deck to the top of the crankshaft bore. In this case the liners protruded further from the deck and the gasket used stock fire rings but a thicker composition gasket to make up for the difference in the block machining . There was an old service bulletin on this and it mentioned the fact that there were identifying notches cut to the outside of the head gasket so you could readily identify these motors. If for some reason you could have mistakingly got a hold of a pair of these special head gaskets and used them on an engine that did not require them the fire rings would not "coin" properly. Even if this was the case, in my mind, it still wouldn't explain the water seeping past the composition gasket. Ron

Which head gaskets have the notches cut in them the old ones or the new ones? Ron

Had the pleasure of riding behind N & W "J " class northern #611 from Lexington,Ky. to Chattanooga, Tenn. and return, back in the fall of 1983 or 1984? Can't remember which. It's now retired to the Roanoke Transportation Museum. What a shame!!! If they ever bring her out of retirement I'll be the first in one in line for a ticket! Ron

The last old Mack I pumped was a 1941 Type 55 and that was over 30 years ago but one thing I do remember was that It had a small tank on it for oil to prime the pump. I don't know whether the later ones had this or not. We used to use gear oil in it. Ron

absolutely!!!

Looks like a new one! Ron

Great looking job Vinnie! Keep it up. Ron

I don't really know that much about how they operated. The Mack Co. called them Dynamax clutches and U.P.S. used a bunch of them for awhile in there "F" models. They used a special flywheel housing that was sealed because it was filled with A.T.F. fluid. They were operated by a treadle valve located where the clutch pedal would be. I can remember seeing these trucks leave the toll booths and if you noticed when they left they didn't jump around like normal trucks did when the driver engaged the clutch---they just plain flat took off sort of like they had an on & off clutch with no in-between. I think that was the idea of it especially with slip seat trucks, so the clutches would always engage the same way and therefore should last longer. Ron

Looking for brake and clutch pedal pads for "E", "L", or "A" model Mack Ron

That was as stated above a Mack wet clutch of course with a catchy Mack name--- the Dynamax clutch. A lot of the Buster Brown day cab "F" models were equipped with these. Ron

Looking good Vinny, you and your Papa keep up the good work!!! Ron

Me too! Ron
