Latrobe Construction B-61

I had a few of the B Models running at an equipment show this summer.

Yes they are all in my collection.

Truck 7 B-63 SX 2485

Truck 5 B -63 SX 3148 Truck 6 1951 A-40 2848 Also From former Latrobe Construction

Truck 3 B-63 SX 3155 Truck 4 B-63 SX 2528 Both also from former Latrobe Construction

I thought it might be interesting to share some pictures and history of the Old Bulldogs I have collected. Truck 1 B-63SX 3156 Truck 2 B-61S 54843 Both formally owned by Latrobe Construction.

I Just purchased my first Mack Truck. It was owned by Latrobe Construction Company. A large earth moving and quarrying company in Western Pa. I grew up watching these trucks running up and down Rt 30. Is there any aftermarket service manuals available? I would like to service the truck but I know nothing about what it takes fluid wise and quantities. Thanks
