60 starter

[Herpdawg]

The starter on my 60 barely rolls the engine over, but just
enough to start it. Have had it to a starter shop and they say it
is fine. Even with a new battery and new cable, nothing
changes. Thoughts?
Thanks

Use your multimeter on the voltage range and find the VD across cables and connections while cranking . Should measure the battery terminal voltage while cranking.

Should have 2 six volts from the factory. I would put the largest 12 volt ln it that fits, like a group 31 or similar. You need the extra cca to spin the engine over, especially if it has high compression pistons or a power block

On my 60 i had my starter rebuilt and it was still a little sluggish. Ended up putting a 12 volt from Sears with cold cranking amps of 850 & in the 4 yrs. since it has done great !

Is the other end of the ground cable still connected to the tin battery box? If so, try moving it to something more solid. On my 50 I bolted it to a hole down by the rock shaft.

Actually just moved it below the box attaching it to the bolt
below it. No difference. The battery is good and it is 850 cca.
Same battery as what I have in my Dodge Cummins. Thanks
for the reply.

 

[Herpdawg]

Will check that next. Thanks.

What cable did you replace? The cable from the battery to the starter or the ground cable? The ground cable gives many times more trouble than the cable going to the starter but that tractor is 65 years old so anything is suspect. The old cable you did not replace could have corrosion in the wire inside the battery end or the eyelet on the other end. If all ends are clean, the connections are good and the battery is good You might have a problem like a bad field coil in the starter. The starter might bench test OK with no load but fall on it s face when it tries to crank the engine over.

Going to troubleshoot or randomly throw parts at it ?

All ends are clean. Could be that coil. Spins good out of
tractor but struggling to roll tractor engine. Thanks

You are guessing . Do you have the time and money to randomly throw parts at the tractor ?
Get a multimeter and measure for low voltage at the starter . Then track down the cause of the low voltage .
