Does anyone have an NP435 clutch fork? I have one that is too long between the pivot and throwout bearing center line, and one too short in the same area. Need asap so I can finish a parking lot trans swap to drive home for Thanksgiving. Running an NP435 from a 78-ish with an 84 hydraulic T19 bell from a Cummins powered bread truck.

 

What series is this "bread truck" w/a Cummins diesel? It has to be at least a 600 series, but which one: C series, F series, LN series or?

 

I dont have the foggiest of an idea. How do I tell when I only have the flywheel and flywheel housing?

 

The term "bread truck" was associated with the 1953/77 P Series Parcel Delivery, because many bakeries used them. But none came with a Cummins diesel.

Is there a casting number on the bell housing?

There's no such thing as a trans specific clutch release lever (fork).

Clutch forks are specific to certain vehicles with certain engine sizes, with Warner/NP435 4 speeds (and sometimes NP 5 speeds) as well.

 

Go to the forum: 4btswaps.com They are a great source of information and also have a parts classified section. I have learned lots from the forum and it has helped immensely during the 4BT swap into my 78 F150.

 

I am on there. I have been through every Cummins group on facebook and not many people have any info because everyone runs five speeds.

NumberDummy, at least in the Cummins swap community we refer to the Grumman Olson's such as Chevy P30's (unsure of years) as bread trucks.
