I bought a 3800# governor spring and i'm nervous about clipping it to size. I Couldnt find a thread about it is there any precautions i should take before i start clipping coils off??

 

Has nobody done this before?

 

i never clipped one

 

I know you have to with the 3600, 3800, and 4200 springs because they're longer i just want to know if i have anything to worry about if i happen to get the spring a little short or a little long if it would goof up anything in the pump?

 

ive never heard of clipping a spring? ive shimmed out several to make them longer and thus have more pressure which is what a gov spring upgrade is, so im not sure what you are trying to do??? a loose spring in the pump will cause some SERIOUS idling/drivability issues. you want to cut the machine flat part of the spring off? the remaining coils will still have the same tensile strenght just an overall shorter dimension. so if you cu a 1/4 inch off you will haveto add 1/4inch of something to take up the space, once the space is taken up you will have the same and potentially a higher spring pressure because there isnt as many coils to bend/distord. 1 coil from this spring is still the same tensile as a complete spring however 1 coil WILL NOT compress, this is why i think spring pressures -could- increase which totally negates your assumed reason for clipping it.

is this like a tractor supply go fast spring that comes like 2 inches too long or something or is this a spring that you specifically bought for your injection pump?

 

Don't take my word on it as the truth, but I have read a loop and a half or so. The springs have different tension but some are longer and that is the purpose of clipping them. I have just read this not done it, so take it for what it's worth.

 

I cut mine to same length as stocker. Gotta guesstimate to leave enough to make the loop on the end.

 

Thanks fox racer, I just wasnt sure if i could screw something up if i didnt get it exact size.

Its a governor spring from bosch I think its intended for a VW pump so it's a few coils too long. Im running a VE pump

 

Its a precise measurement but if your close you can make fine adjustment with the fuel screw and idle screw. Also the throttle shaft can be indexed.

I wish i would have taken pictures when i did mine but i usually get caught up in the job and dont document it as well as some.

I feel mine probably is a shade too long but i dont want to rev it past 3200 much till i get valve springs. I have plenty of low end fuel but starts to go soft after 3k. Need fuel psi gauge.

 

Did you clip both ends or jus take it all off one end? I never think of taking pictures til i get done either. Do you have a fuel system on it or a stock lift pump?
