I seem to remember that there is an issue over the way the different pumps work, I think it was something to do with bypass valves which are needed to allow the leg to jump up if it is hit hard enough Might be best to ask Mike at Lancing because I really can’t remember for sure. Des

Cheers,

This one didnt have an A frame on it,other than that cant give you much more info as they all look the same.Did it have a white electrical box close to the pump to house soleniods etc., cant think of any other give away signs. I will ask Nev.

Leroy, missed the thread a bit as i have been away in italy.

Suggest you remove your pump, make a simple assembly to connect the hoses to a gauge and check it (you said that you had machining capabilities) - then if its not the pump its the leg. Would then check the valves in the top of the rams. These pumps were exceptionally expensive - over £1000 if my memory is right. Mercruiser ones are simpler and less than £300.

Brian thumped the leg of a rock as you know so it may just be the ball bearings seating properly in the ram.

Paul, I am in the middle of typing you an email about your drive.

Gary, To buy a set of tubes from one of the main tube makers is going to cost between £3000 - £3800 + vat. Then you can either fit them yourself - a bit of hastle or possibly pay the tubemaker to fit them if they have done that type before - they are screw on, and there are millions of screws.

The trailer will cost anything from £500 upwards for a second hand one. Ramco.co.uk have one on their next sealed tender and they normally go for approx £400 for a twin axle braked. A good secondhand roller coaster type will cost £1200-1500 .....

Gary, there was a set of P22 tubes for sale before Xmas. think Paul Tilley had them for sale. He is a toob maker so might be worth having a chat with him. He posts on here under his own name.

If you think you might have a ram problem a word of caution, there was batch of rams that were not made correctly, not naming names but they were made in the UK

These rams are double sleeved to allow oil to the further end of the ram without using an external pipe and as far as I can tell the inner sleeve was too short on the bad batch and would move resulting in the ram having oil pressure on both sides of the piston at once

You can check this with an air line by putting air in one side, if it is wrong, you will get air out the other side having previously made sure the bypass valves are seated correctly Having said that I found that the inner sleeve on one set of rams worked ok on air pressure but once I put hydraulic pressure on them they failed
