Spirol Pin
 

what size spirol pins do i need for the drive shaft of a 1450, price and where can i get them? Thanks

I thought this would be an easy question. Much to my surprise, I looked up the Parts Manual for the 1450 and could not find the drive shaft spirol pins on line. I went to my paper version and again, saw no listing for the spirol pins.

IIRC, seems that they are 1/4" in Diameter and 1-1/2" long.

They can be had at.... McMaster-Carr

The local Ace Hardware carrys the 1/4" spiral pins. I picked up a pack there when I rebuilt my drive shaft.

I know I got 1/4 inch pins at my local Ace too.

from mcmaster do i need to get standard or heavy duty? Would stainless be better?

Heavy duty. I don't think I'd bother with the SS ones; they're expensive and not any stronger.

Roland - all but one of the 'Spirol' pins for the 1450 hydro-transmission assy got lumped together under Part 7 'Self Aligning Ball Bushing', and specifies three 1/4" x 1 3/8" Heavy Coiled Spring Pins.

I checked my local Ace, True-Value, TSC, Lowes, H-D, and other hardware stores and all I can find are Roll (aka Tension) springs. DX3 - I'm wondering if you actually found coiled spring pins (aka Spirol pins).

On the left is a Coiled Spring pin, on the right is a Roll (Tension) pin. Spirol is a brand name for their coiled spring pin, much like Xerox has become synonomous for photocopy.

i work at a cheese manufacture facility and we have miles of stainless pipes and thousands of stainless bolts, been there for 30+ years and i can tell you that you do not use it for it's strength properties. you use stainless because it is easy to clean and maintain a sanitary environment.

have seen many a bolt striped out over the years that if it was not stainless would not have, stainless is softer but shiny and easy to maintain, rust wise

Actually, the McMaster-Carr spirol pins in SS and regular steel have the same double shear strength (SS ones are 420 if you were curious) but they cost 5x as much. I do agree on the strength though; most people have this misconception that the SS hardware store bolts are stronger than a Grade 5, when in fact many are weaker than Grade 2 bolts.

As soon as I get the camera back I'll show you a picture of the Coiled spring pin I purchased at Ace :). Something to remember is, not all stores carry the same items in all areas of the country.

Sorry for pic quality, had to use phone camera.. I just use the dremel to cut off excess..

When viewed from the top, do these bagged pins look like the pins on the left or right of my photo? And is there a Hillman stock number, or just the bar code number?

Again, bad quality but it looks like the one on the left, it coils, is not split.

I wonder how long those will last. They appear to have one less coil than the OEM and McMaster-Carr spirol pins.

I just checked the Cub Cadet OEM site and their pins only seem to have two full coils vs about 2 1/3 coils on my old part. For the heck of it I'll try and visit my local CC dealer next week and see what their $5 pins really look like. Talk about sweating the small stuff! But sometimes that's what makes it fun.
