Spirol Pin Removal

[35boulder]

When removing the clutch shaft coupling, do you just tap out the spirol pin with a punch?

Best to use a spirol pin punch.
Pick up a set, they will come in handy.
A regular punch will suffice though if need be.
Be sure and support the driveshaft before whaling away on it too much.

Where would be the best place to find a set of these punches? Thanks

I got my set from Sears, bought them 10 y.a. still punchin'
Using a 3/8 deep socket and extension makes it come in real handy for those hard to reach places.

X 2 on supporting the driveshaft and or yoke well before having at it.

Here's the set I bought. The punch tip has a little nipple on it to center it on the roll pin. Keeps it from skidding off and reduces likelihood of mushrooming the pin. Amazon actually has a bunch of different sets if you search for "roll pin punch set."

I have found an air hammer outfitted with a blunt shank until flush then a small diameter punch to be my favorite weapon for this task. haven't had 1 put up a fight since i found this out. x3 on support it before pulling the trigger

Thanks for the responses. Suggestions on best way to support the shaft? Also since I have never removed a spirol pin before, is there a top/bottom or is it like a standard roll pin in that way?

I put a hydraulic jack under the coupling and raise it up snug, taking up some weight. Block it up if you must, but it's best to have the jack directly on concrete. You want to minimize stress from the impacts on the bearings in the hydro or reduction drive.

The pin does not have a top/bottom, so can be driven either direction, but there is often an indication which way it was driven in by some mushrooming of the driven end. Drive it out the other way.

PB Blaster or Kroil applied ahead of time and allowed to soak can help. Sometimes some heat is helpful but don't overheat any oil seals. Worst case (only had to do this once on the base of the manual lift lever on a 108) drill it out with a carbide drill bit. Standard drill bit won't cut the hardened spring steel in the pin.
