L and R-Series Library

L and R-Series Library

For those of you that used to frequent the previous website – “Restoring Cornelia”, I have great news. I just completed transferring the L and R-Series documents from the site and have created a new “R-Series Library” page for you (contains as much L-Series information as R-Series, though).

In the new library you will find the MT-97 Parts Catalog, an Inter-Sub Manual from 1959, the CTS-11 Service Manual for L-Series Trucks with the CTS-12 R-Series supplements, a Carter YF Service Procedure for rebuilding the carburetor, the CT-62 L-Line Product Information No. 2 Sales Guide, and a Wiring Diagram for R-Series Trucks.

Love You Gearly

Love You Gearly

As with all old vehicles, you need to place some cardboard and/or absorbent pads beneath the vehicle if you want to reduce the number of oil stains on your garage/shop floor. I had been noticing that the pad beneath the differential seemed to be collecting a little more oil than I thought was desirable…

Also, since I hadn’t changed the gear oil yet in the differential, I felt I could take care of a few things at once.

The differential cover came off easily enough. The oil (as differential oil usually does) looked pretty sludgy. More importantly, I did not see any chunks of metal or shavings in the drained oil. Very happy about that!

Grounded

Grounded

I took a closer look at some of the wiring connections on Cornelius, and noted that the main ground strap from the battery to the frame looked tired and frayed.

While grounding is critical for any automotive electrical system, it is especially so on a 6-volt system! Connections must be clean and tight throughout. Also, you need to remember that a 6-volt system utilizes twice the amperage (current through the wiring) that a 12-volt system does, so the wiring needs to be sized accordingly. You can use #2 wires for the starter and ground on a 12-volt system, but you should use #0 for a 6-volt system (no less than #2 for ground strap).

We Have Ignition!

We Have Ignition!

The engine has been running pretty well, but one item on the checklist that I should have verified before now is the point gap in the distributor.

First I verified that the distributor is indeed a Delco-Remy, model 622R. Based on that, the Service Manual calls for the gap to be set between 0.018″ and 0.024″. When I checked, the gap seemed a bit wide, and I reset to 0.020″ to be in the middle.
