Fuel Pump Assembly, advice needed

[Evipz]

I’m trying to look for a FIELD MAINTENANCE level TM for a Fuel Pump Assembly (NSN 4320-01-524-4467). When we try to crank it, there is almost like a grinding noise coming from the Starter or the Flywheel. I can’t put my finger on it.

I have TM 10-4320-372-14 & TM 10-4320-372-24P

There is no other TM for this equipment.

Describe the problem better. As soon as you try and start the engine, it makes a sound? Or after its started to turn over a while?
