Calling on all you trailer experts out there, perhaps you can answer my question and put my mind at rest.
A couple of weeks ago, a suspension unit snapped on my SNIPE trailer which carries a 4m Avon Searider RIB with a Mercury 50HP engine. I searched around for ages for original SNIPE parts but could not get any. I was told by a couple of trailer shops that the suspension units were standard suspension units and as long as the load handling and measurements were met I could use any suspension unit. I measured up and finaly purchase a suspension unit rated at 750KG that met all the hole measurements on the trailer. They fitted perfectly and the trailer is now on the road again. I replaced the suspension units, hubs, bearings and also wheels on both sided of the trailer as it was quite old and I considered doing one side false economy.
After fitting, there was a couple of things I noticed. The wheels I purchased were slightly thinner than the original and I noticed that it specified maximum axle weight of 600KG.
Is 600KG enough to safely hold the above RIB with the engine, console and 50litres of fuel including a backup engine weighing 20KG and a few accessories such as life jackets etc ?
Secondly, I noticed that the wheels seemed to be closer to the frame than they were before. I then found out that there were 2 types of suspension units, a short stub and an extended stub. I had fitted the short stub. This seems to run fine and is far enough away that it does not interfere with the frame but I have a feeling that the old ones were the extended stub type.
Is this going to cause any handling problems ?
Does it matter that the wheels are slightly thinner than the previous ?
I replaced all of this because I have had a few problems with the trailer so I replaced everything including coupling, rollers and all the suspension and wheels.
Am I fine with what I have got or do I need to exchange a few items ?
Lastly, does anyone have an idea of what the total weight load is on the axle with all this combination ? Because of the wheels, it looks like my trailer is now rated for 600KG combined axle weight. Is this enough ?
Many thanks in advance.
