Chev C60x rebuild

[Ganmain Tony]

Gday Danny,

6 Volt stuff is easily available. Keeping it on 6 Volt means you wont fry instrument gauges.

Yes your starter motor turns slower but if the fuel is at the carby and choke is set right, it will start every time. A primer for the fuel system is really handy as the truck is not usually driven often and therefore dry fuel systems are always requiring priming.

Primer does not have to be electrical, I use a Marine type you sqeeze until it goes firm indicating the bowl in the Carburettor is full. My fuel lines are a rubber hose however. (The originals are steel)

Wiring Harness available from Vintage Wiring Harness in Victoria.

Test your coil - dont assume because its old, its had it.

A very good 6V battery that supplies over 600 cold cranking amps is available at Westrac. And it is perfect for these old trucks.

Hope this is a help not hinderance - does come from years of trial and error.

Thanks Tony, I have decided to keep the 6v system. Can get the parts easy enough, points, coils etc. May need to look at the battery, may be to big for the tray area. Have not had any joy so far freeing up the motor to try it to get it running.

G'day Tony,

Would something like this be close to the mark? It is a Cat battery from Westrac? Accessed 23rd January 2022 from, https://parts.cat.com/en/westrac/8C-3617

8C-3617: 6V 1 BCI Wet Battery
• 6V Premium High Output maintenance-free accessible wet battery
• 650 cold cranking amps
• 130 reserve capacity minutes
• 100 amp hour capacity

Kind regards
Lionel

• 1 BCI group size

Working from memory (can be dangerous) I think I put a group 34 (12V) into the battery box of my C15A. It fit but without huge clearance in any direction. Looking at the sizes in a chart of BCI sizes found at https://www.jegs.com/Sizecharts/bcigroup.html you may find the group 1 battery tall enough that the terminals could contact the cover for the battery. You measurements will tell the tale.

Have you poured lots of diesel down the plug holes? Then let it sit for a few days at least before trying to turn it over by hand.

A pry bar????

Remove the sheet metal cover at the bottom of the bell housing..... it will reveal the ring gear......... with a long, long flat tip screwdriver try prying the flywheel using the teeth one way then the other....back and forth....... you may need to pour more diesel even into the carb intake ...... literally flood it.... let it sit and try the pry bar again and again back and forth......

If it does not work.....quit....no point being fanatical about it...... it will need to be taken apart........

Good luck....

PS....... may be silly but make sure the tranny is in neutral and that the
CLUTCH DISENGAGED....AND IS NOT RUSTED TO THE FLYWHEEL.......

[Danny Devers]

Thanks Bob, it is in neutral and rolls easily. I am not to stressed on the motor would be nice just to see if it runs before pulling truck apart and see what issues it has. Will try the pry bar, may be able to rock it backwards and forwards that I can’t do with the crank handle.

Gday Danny,

Again - a bit slow on the reply. One of reasons to suggest the Westrac battery is
it is a compact size. Check one out for yourself if you are able.

Lionel has posted an example.. might be worth a look. The one I have is

8C - 3629

They are not cheap - but well worth it.
