Here is the pictures of the distributor, I took it out between rain drops. As you can see it is easy to put in the wrong one. The gears are in the lower pedestal which connects the tachometer and oil pump. The firing order is correct. When the rain stops I will do a compression test. The advance does advance clockwise opposite the counterclockwise rotation.

When Im looked up my delco dist number in the motor book. my number 1110057 is listed as a clockwise rotation. The book from the Mack museum on my truck calls for a counter clockwise rotation. I pulled the cap off and cranked the motor and it spins counter clockwise.

Upon researching my running problems I found out that thr distributor in my motor is one for a clockwise rotation not counter clockwise. Any one know the correct one for my 41 type 45 with a EN-330 motor Fred

More info: I tried to adjust timing, but could not get it any better.

Now that I have conquered the starting problems, I am having running issues. Before I found out I was not charging my engine would run smooth, but only at 15" of vacuum, under any throttle it would break up and vacuum would drop to 12" to 13". I fixed the charging problem and now it runs rough at idle, vacuum is now down to 12" to 13" and 10" when throttled, with it breaking up bad. The person I bought the truck from changed the crank before I bought it gue to it being cracked. I am thinking he might be a tooth or two off on the timing gears. Any one with ideas?

Thanks to a;l that replied. The timing was to far advanced. Now it starts like a champ.

Thankclk s to all that replied. The timing was set to far advanced. Set the distributor back and now, it starts like a champ

I need thoughs on my motor. When I try to start it, it seems to hydro lock and stop turning right before if wants to fire off. It will crank fine up til this point. Then it seems to stop. If you try to hit the starter switch it turns a quater turn and seems to stop again. If I open the choke and throtle like to clear a flooded engine it will start to hang and then spin normal again. I have checked the starter and cables and they check out good. ??????? I have a 41 type 45 with an EN 330 motor Any one with ideas ????

Looking for a parts source to rebuild my starter. It is a D.R. 737-T. Thanks Fred

Any one know what the correct carb should be for a 1941 type 45 with an en330 motor? One place I saw mentioned a Stromberg SF5. Currently I have a Zenith carb on it. Also should there be a governor?

I am looking for a pump throttle asy. and pump handle to restore my 41 Mack to pumping operations. I have enclosed a photo of original pieces. Fred

Nice '41. Saw it on ebay last week. Almost bid on it but it came without the engine, supposedly. Which pump handle snapped, the one down by the running board, under the pump? Snapped off where? All it is is a solid steel shaft with a small bend in it. The small flange on the pump end has a cable eye (for clutch engagement) and slider (into the pump transfer case) I think.

I had some extra parts from the pump engagement lever of an old Mack stored some place here. Let me know where it snapped and we'll go from there.

Did you get an engine with it?

It is the one down at the pump that says prime, neutral and pump. It snapped off 1" before the slider. This one looks like it is cast instead of steel. Looks as though the metal fractured, the metal looks porus instead of being clean. He rebuilt the motor from another oneand installed it. Sounded great, I just need to tune it up with new plugs, cap and rotor. Any help would be great. Fred

Just bought a 1941 E Model Fire truck. Planning to start restoration soon. Any one know where to get a pump handle for it. The person that had it try moving it with a pry bar and snapped it. Ant help with other parts sources would be a great help.

Looking for a radiator cap for our 38 E model Mack. Does any one know where to start looking for one? Fred
