Replacing the Front PTO aka IH-61313-C93 Clutch Assembly.

I apologize if this has been covered before. I tried the search and couldn't refine it enough.

I had to replace the front PTO aka IH-61313-C93 Clutch Assembly on my Cub Cadet 1650.

I need to know what parts are needed for the bolt asembly which secures the PTO pully/armature to the shaft of the tractor. I need to know how the spacer and washers are sequenced on the bolt where it secures the pully/armature to the shaft of the engine. Does it need to be torqued?

I also need to know the gap between the field/magnet and the pully/armature and how to adjust it. It seems that the magnet over the field and the pully/armature both slide toward and away from each other. I know the plate with the springs under it has something to do with it, but I can't quite figure it out.

Picture would be appreciated.

Thank You.

Here is the service manual for the Quietline series http://ihregistry.com/manuals/service/86ser.pdf
You better have not use dial up to download it(145 pages). The clutch is section 2-81 (pages 106-109)

Thanks Geezer.

I don't remember seeing any shims between the driven disc and the driving hub of the old assembly when I removed it and it is the black one.

The one which needed replacement was new??? within the last three years, installed by a local small engine mechanic who rebuilt the engine. From what I saw, what I have been told, and from your kind response with the manual, I have some suspicions that he did fine with the engine but may not have known enough about the PTO to install it properly which is why it self-destructed in less than three years. It does not look like he replaced the field either which is ok but it does show some insulation cracked and missing from it's face.

I'll have to check with the dealer from whom I purchased the new assembly about the shims. The one which came with the tractor when I bought it used, lasted for 20 plus years which is what the dealer told me was the expected life cycle for this unit. They also said .005 between the rotor assembly and driven hub. The manual says .010.

Any other suggestions would be appreciated but the manual was very helpful in giving me some additional things to be aware of. I definitely need to check the gap between the coil and the driving hub before proceeding.

Much Obliged.
