I am repairing the compression release mechanism on a Tecumseh HH120 engine. It consist of a 1/8 pin that is held by a spring to help lift the exhaust valve briefly during the compression stroke to help the starter generator be able to turn the engine faster. The pin on mine is worn.A machinist helped me to remove the pin and we found it to be 1/8th inch diameter and just under a inch long.
He told me about a 1/8th Perforating punch that is used in a machine to stamp holes in sheet metal. He said it would work with little if any modification. His catalog only showed a 3/16ths size.
So I need to know where to find a 1/8th Perforating punch . It needs to be 1 inch long and have a head on it like a nail kinda. I can cut length if need be.
It is made to fit in a machine to punch holes.
Any ideas where to find 1? There is some that are knurled, this cant be knurled.
Would this work?
If the pin that is shown in the link posted above by Andrew isn't what you're looking for Mack, try looking for a mold maker supply house.
Plastic injection molds use hardened pins with thick heads like nail heads. These pins are referred to as ejector pins and come in many different lengths and diameters.
Just a thought.
How about just buying a 1/8" drill bit and cutting off the shaft part to the length you need.
Diameter should be precise enough and its hardened steel.
It's soft but the butt off a pice of 1/8" welding rod?? Bud.
How about these: http://www.plastixs.com/ep01.html
Andrew that would work well, Ken, I think those are 6 inchs long. Which would give me plenty of wiggle room if not spares! and for that price, not a bad deal.
THanks for the help.it is to late now for me to call and order but I will get 1 from 1 of those places tommorow.
Gota go plow under where the corn and taters were in the garden!
The pivot pin from Minsumi would work perfect.
I just got a form by email I have to fill out to set up a account to order from them. Thanks again for the help.
