Jcb3c 2
Posted: Fri Mar 22, 2024 11:31 pm
Hi all i haven't posted here for a while although I've been regularly lurking in the background. Always makes interesting and informative reading.
I have been giving the jcb3c a good going over to try and sort out a few issues that have been there since I've had the machine.
First one was a crack in the hydraulic rail . It has been leaking hydraulic fluid from a spot by the triangular plate beside the front wheel. It has been a steady drip even when the machine is not being used and beside the pollution its surprising how much fluid it has been losing.
I jacked the front of the machine up high and supported it under the front axle hoping the oil would run towards the back of the rail because I wanted to weld it. I drained the hydraulic fluid also removing the plate as I thought I might as well clean out the suction strainer while it's drained down. Plenty of oil sludge in there and the strainer was absolutely blocked solid. This was probably due to the main hydraulic filter being in absolute tatters not much of it left. I changed this when I first got the machine. 2 solid hours of cleaning later and the strainer was back in place.
On with the welding. I had to remove the front wheel to get better access to the hydraulic rail. Having a good look at it someone else had been having a go at it . Now I'm very much a novice welder but it was bl### y awful . This had to be carefully ground right back to good metal . After it was removed I could see the crack was small and very near the top of the triangular brace . Perfect for a small patch which I made out of a bit of angle iron . No oil dripping out now so I went for it and using minimum power I could get away with I welded it in . I was worried about blowing a hole through the rail as I don't think they are that thick but it was successful.
Little bit more grinder work to tidy it up .job done.
I also decided to go round the welded seems with por 15 in case of any pin holes . Coated with paint to prevent rust . I think it's totally sound now but will have to wait to find out when the new oil arrives.
Next job is the leaking sump . I already have a new gasket and have drained the engine oil . I also renewed the oil filter which was a swine of a job. I must admit the air was a bit blue when trying to screw that stupid long bolt back in . It's got a mind of its own . Whoever thought that was a good idea wants a kick where it hurts.
Tomorrow sump off, new gasket and replace. I hope.
Any suggestions about the best type of oil to refill with? Especially now I will have a clean sump and clean filter .
I am also going to clean out the power steering filter while the hydraulic oil is drained.
Anything else I should be doing while the oil is out?
