Spirol Pin

[tubbyfirefighter]

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

[R Bedell]

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.
