D4 7u recoil spring bolt replacement

I have an extra D4 recoil spring bolt that looks to be in good condition. $100

its more about doing a beefy weld around the flange end of the recoil bolt mate
that or use a nut and weld it on.
if i remember its 1 3/8 " rod which is a little larger then 33mm , just double check that first mate,

i ended up using 1 3/8 " round bar, having two square cleats laser cut with the round hole in the middle and then bevelled
the bar and the cleat and went to town with about 130 amps on 3mm rod.
seems to be doing just fine, though its only had about 2 hours work. : )

they can still be scary, especially if you are kneeling behind a dozer blade with your double gloved hand hand holding the oxy round the corner trying your best to blindly
cut a siezed nut off and waiting for the BANG and bits to fly across the yard... : )
always seems to be about the time the dog has smelt your fear and walks right in the path of destruction for a gander.....

it takes a fair bit of curry to do the nuts back up when you go to compress the spring again if you dont do it in the press.
the worry with pressing recoil srpings in presses is if they are bent a little out of shape from sitting on an angle once the recoil bolt breaks and slipping sideways once loaded.
the whole BOING and a spring sends itself sideways into your chest kind of scared me more then the oxy/ crouched behind the blade crapping yourself method : )
yours might not have been as out of shape as my ones though.

I would doubt if the tensile load in the bolt is any more than 20 ton. My 941B was only 14 ton. I always double nut the bolt when under tension and handling it--the nut stripping is more of a concern than the bolt failing.
