A shear pin is located on the hub on the back side of the pressure plate. Look behind the pressure plate, below the clutch brake assembly and in front of the transmission or creeper gear if installed on your tractor.Is the sheer pin at the motor end or the trans end?

Suppose to be hardened bolts. About 45 minutes ago I stopped by the local implement dealership and picked up a grade 8 smooth shanked bolt to replace the existing bolt holding the pressure plate to creeper gear input shaft. The bolt I removed was full threaded, badly beat up, unknown grade, and obviously not original or up to standard.Landreo wrote:Neither of the two 5/16 bolts is a shear pin but are hardened bolts, their function is not as a safety shear pin. Replace them with at least grade 5 bolts.
By clutch, I assume you mean the pressure plate.salemlowboy wrote:Thanks for all the help guys,I have some reading material now and see how it all works.After messing with it this morning,the drive shaft ,clutch turns,I'm thinking it may be the bolt on the input shaft.i will have to wait for better weather to check that out since tractor is stuck in the driveway and not able to push it back into garage,uphill grade.
Salemlowboy didn't mention a creeper gear, I did because I am currently working on the clutch of my 154 which has a creeper gear.outdoors4evr wrote:Now you mentioned a creeper. You also might have the creeper "in between" gears.
