    I just got my first plow truck and plow. It's a 93 GMC 3500 with a fisher 8' straight blade on it. I thought it was going to be a easy fix but I am having trouble figuring out how to install the new trip edge springs and bars. Can anyone help me out and tell me how to get them on with out going to the dealer and spending over $500 to do this?

    You could make a sping compresser if you are handy or buy the tool to install them.. If they are new they come compressed to just bolt in

    I purchased the new springs and bars from Napa and they weren't compressed.This plow is around a 1993 if that matters at all. As far as a spring compresser I bought one for strut springs but the problem I have with that is on the 2 outer springs there is the rib for suport right next to were the sring goes so I can't get it in placve with the compresser on and for the 2 in the middle the pistons for the power angle are in the way. Also I can't use a normal spring compresser because the bar for the sring has to be inside the spring when it is compressed and installed. This is a newbie question but what is the tool called to install those springs?

    Compress the sping out of the plow on the bench and put a bolt through the hole in the bar to keep the sping compressed.. Install spring remove bolt...

    If I compress it on the bench and pin it, I will not be able to install it because the one hole I have on the bar has to be above the top plate on the plow for me to bolt it in place. This plow has the old style fisher springs on it.

    The dealer is going to charge you $500 to install springs?? You could always buy the tool for maybe 30 bucks ? Sorry my bad on the hole placement.. You could always drill a new hole.. or make a tool if you have the facility to do so.. or adapt the one you have..

    yeah they said $500 was the minimum to install them and they wanted $90 per spring and bar combo. I was thinking about drilling another whole to pin the spring down but I'm not sure how I would unbolt it once everything is in place with out getting hurt when I get that bolt out. I'm having trouble finding any info on a actual snow plow spring compressor. The strut spring compressor we modified to fit in the spring but the problem with that is 2 of the springs have the suport rib next to them so I can't use it and the 2 in the middle have the angle pistons in the way so I can't use it there either. Does any oen have a pic of the tool so I can try to make one or does anyone have alink to were I can order one ?

    You'll have it done within 30 minutes of opening the box. As my brother says "Tit".

    that looks like it's for a different style springs but for $25 it's worth a shot to see if I can modify it to work.

    THanks for the link and pic.

    I used it to change out my buddies 1990 Speed caster springs just this past summer. I had initially bought it to do my new springs on my MM1. A fellow PS member has it now....I think.

    When I did mine, I slipped the top of the spring into the upper slot, then slowly pried the spring up and on to the cutting bar mount with a block of 4x6 and a 2x4. Installed the lower bolts and finished. Had no luck with the spring tool; it snapped the threaded rod.

    I tried to buy one from my dealer. They don't use it. They use a shop crane to lift the tab by the top hole. Then put a pin in the lower hole. My dealer said to use a piece of pipe or a bar with a section of chain. Put the bar over the top of blade and push down which will lift the spring tab. Then you can put the pin in the lower hole.

    I'm going to give it a shot. I'm not exactly sure how I am going to get that on the bar with the spring down. the spring and bar combo I bought the springs are about 4 inches higher then the top of the bar and about 6 inches total past the hole were the bolt goes in to lock it in place on top of the plate. and the bar itself barely fits in the slot on the top plate.

    I second what repoman suggested langscornergarage.com or ashsupply.com are both great sources for fisher parts the spring compressor is only 25.00. I bought about $400 worth of spare parts from ash supply before the season and it was here in a day. Great Service.
