Re: Starter interlock question
Outside of being stopped at a stop light, I never used a clutch on
any of the tractors I drove.

With my Kenworth I had to use two hands on my knee to release it. Like
there's a reason the clutch pedal is so... big and you can barely even

Re: Starter interlock question
I think you got the direction of the load bass-ackwards - pushing on
the clutch pushes the crank FORWARD. Throwout compresses clutch
springs with the flywheel essentially on the other end of the spring
so force is in the same direction as the throwout travel.
Like it or not, at sub-zero temps it's about the only way to get the
@#$% thing started - the transmission oil is like stirring putty and
I've seen it stop smaller engines dead when you release the clutch the
first time. Unless it's been sitting for a long, long time (like
years) there's still an oil film on the thrust bearing so the wear
should be neglible unless you start at wot. A more severe downside is
wear on the throwout it's cold.

Re: Starter interlock question
I should have said 'toward the radiator' or some such thing; mechanic's
perspective is always from a standing position in front of the vehicle looking
at the windshield.
Haven't driven in sub-zero temps in quite a while, but I do remember my old
'63 Dart slant-6 with that lovable 3-on-the-tree that was HELL to shift on a
cold morning. Never had trouble cranking it though. Most everything I've
driven in the last couple of decades used ATF in the tranny, which shifts
nicely regardless of ambient temp. Don't know what the 6 in my TJL uses, but
knowing DC, it won't be ATF.
I should probably qualify the original intent as more of a convienence than
mechanical neccessity. If thrust and TO bearing failure was truly a problem
due to clutch disengagement while dry firing the engine, Jeep would
discontinue the clutch interlock circuit in a heartbeat.
Those concerns aside, it's NICE having it disconnected. Spent 4 hours
yesterday purging all that dreaded Dex Cool, and being able to just reach in
through the window to start 'er up was damn convienent.

discontinue the clutch interlock circuit in a heartbeat.
Those concerns aside, it's NICE having it disconnected. Spent 4 hours
yesterday purging all that dreaded Dex Cool, and being able to just reach in
through the window to start 'er up was damn convienent.

perspective is always from a standing position in front of the vehicle looking
at the windshield.
Haven't driven in sub-zero temps in quite a while, but I do remember my old
'63 Dart slant-6 with that lovable 3-on-the-tree that was HELL to shift on a
cold morning. Never had trouble cranking it though. Most everything I've
driven in the last couple of decades used ATF in the tranny, which shifts
nicely regardless of ambient temp. Don't know what the 6 in my TJL uses, but
knowing DC, it won't be ATF.
I should probably qualify the original intent as more of a convienence than
mechanical neccessity. If thrust and TO bearing failure was truly a problem
due to clutch disengagement while dry firing the engine, Jeep would
discontinue the clutch interlock circuit in a heartbeat.
