How to peen/mushroom throttle plate screws

[Matt_E]

Well? How is it done?
(If it requires a special tool, I do not have it)

Easy Project

Matt,
Run down to the Snap-on truck (LOL) and buy "Needle nose" vice grips.. Then grind one side of the vice grips into a point, so when you close the pliers on the throttle plate screw the pointy side splits the screw and mushrooms it.. (just like a log splitter at home on the farm).. USE Loctite of course.

Snap on truck

Any idea what they cost,sounds like a good idea unless your cheap like me

Use the longer 9" needle nose vise grips for more compound leverage, part number 9LN and they cost under 15 bucks at most hardware stores.

More leverage compared to what?

Split shot pliers.

Thanks guys.
I have those vice grips and never know what to use those for.
Now I know.

Snap-On

I was joking about the Snap-on truck... But I wanted to get the message conveyed.. REMEMBER.. "Quality is Priceless".

Thanks,
Randy

I don't think mine are very good quality. The steel is pretty soft.
I had to re-grind a couple times.

So how did that work out ,seems like it would be difficult.you will be lucky if you have a couple of threads sticking through and you have to try and pinch it with pliers.. Be different if you could get on either end of the screw with the pliers.
Am I missing something

 

[Matt_E]

Worked out alright.
It didn't penetrate real deep, so I punched one in the middle, and one right at the screw-shaft boundary. (Plus red loctite, off course)

How difficult was shaft replacement, and can a loose shaft be oversized or bushed?

 

[sflsurfrider]

i use red loctite and a spring-loaded centerpunch.

 

[Matt_E]

Shaft replacement:
1. Take of throttle plate
2. Take off anything on either side of the shaft
3. Slide shaft out.

I would just get a new shaft if yours is too small.

 

[feartheride]

Yes there are bushings that can get worn out

The ones I did were difficult because the plates had worn into the sides of the carb causing the plates to get burred on all edges,so I had to grind all edges,(4 per carb) down with a pencil grinder trying to avoid touching the carb in order to slide the plates out of the shaft

Pain in the a--

Compared to the cheaper 6" model needle nose vise-grips.

Gotcha.
