After looking at the trailer and noticed that the tires are just rubbing the top of the guards,Decided should remove and replace springs,3 leaf spring,rated 1000kg,Hmm what harm can it do to go heavier??  Got some from BNT(neighbour got a good deal for me)went with 1500kg 5 leaf now fitted have a good 40mm between tyre and guard,left side was cut everything with a cut off blade,right side yep all undid,so guessing right been done recently but going to replace do both sides.2 hrs done.

Thinking they collasped fast as checked when purchased and dont know I thought to check today.Being 3 trips out.

Non Galvinsed but good coverage of marine grease

Ok, I'm going to retract, I used to build trailers for an Auckland hire company, and I now recall that I used to weld a plate to the axle with 4 holes in it and use a matching plate with standard bolts to sandwich the spring.. Hire trailers get thrashed..
However I have never done it on any of my personal trailers.. And one of those had single leaf springs.. And a drop axle.. Never an issue.
But my experience does not over ride anyone elses..

We have never welded a backing plate on an axle as mentioned because we have seen way to many axle failures on that edge. 

Having it welded affects it and leads to cracks over time. People ask us to do them because they wont have to use a U bolt

Good on you for saying that Dave. I only had a chat with the guy on the phone and he mentioned that as a possibility when I talked about wanting robust and easy to wash over other concerns. He did say he'd need to look at the axle. He was going to recommend multileaf until I told him I'll be using it in the salt. He runs singles on his own. 

Just a question: Where are most trailer springs and cMajority of trailer parts in the NZ market are from China.
Generally a mix of other countries but China as always number one

Trojan and the other common names around are getting stuff overseas for years. You dont get a NZ made coupling or a hub/brake set!!!!!

Best thing for axles is to seal them completely so the water doesn't get in. I've seen super rusty box section from the outside that when cut open looks brand new inside.

Nearly all boxsection trailers rust out from the inside, as one the galv coating won't be as good, two ya can't wash them out 100%

Not sure what the implications of me painting it will now have on future galvanising

They will just give it a media/ sand blast...
 Any issues on the inside of the box section mentioned above would still exist thu.

Could drill holes fill with oil, and re plug. Tap a hole, bolt to seal maybe.

That's the plan 👍]]> Wed, 06 Jan 2021 21:03:55 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=134377&PID=1801342&title=leaf-springs-on-40year-old-trailer#1801342 <![CDATA[Leaf Springs on 40year old trailer. : Farmer_Dave wrote:Oh right....]]> https://www.fishing.net.nz/forum/forum_posts.asp?TID=134377&PID=1801339&title=leaf-springs-on-40year-old-trailer#1801339 Author: pjc

Just curious why you went for painting the axle over galv dipping it? I've just built a new axle for mine and debating what to do as I want to use the damn thing not wait for the dippers.... contemplating leaving it raw until I can get some time to dip.

Throw it on go fishing m8.
As you say if need to build a new one, no big deal or cost.

 Cost $40 plus a bit of gas bits 'n peices.
 1st build , makes sec 1/2 or less time.
And want to go fishing.

M8 I wouldn't even bother painting...
 just go.
 Will last couple yrs at least.
 In that time can build/ galv and have sitting ready to fit for a bit of spare time between milkings and feeding out.

 Amazing how things can turn around so different when a few other bits info gets thrown inWink


I'm confused lol, what's your point?
