    JCB 525 Telehander - No foward drive

    Hi, Not the worst one ive seen. I had one where the counter plates welded them selfs together and put the box in constant drive. I would remove the pistons as your this far and seem to have plenty of know-how. The generally end up becoming d section rather than o section over time. The...

    JCB 525 Telehander - No foward drive

    Good progress. The grears on the fwd/rev pack should be locked to the relevent baskets. You need to remove the sealing rings from the ends of the pack and lever the bearings off. Start with a small chisel then get a heel bar each side and they should slide off easily. Then the clutch baskets...

    JCB 525 Telehander - No foward drive

    I hope you have put some cloths down in the front room fiirst! You can leave the disk on the output shaft and in the casing when you strip the gearbox then you dont upset the colapsable spacer between the taper roller bearing. Its worth removing the pump from the front of the box and there...

    JCB 525 Telehander - No foward drive

    Good evening, If you loosen the lock nut and run it all the way off the treaded part onto the black part of the cable. Then remove the allen keys and then turn the body anti-clockwise so it ends up also on the black part of the cable and they you can slide the nipple out of its slot. Bingo...

    JCB 525 Telehander - No foward drive

    Hi, The u section should be near the exhaust siliencer held onto the chassis with a T bolt but it may of been misplaced over time. If you can get the box out and stripped you will be able to rebuild the clutch packs yourself. You just need a workshop press to compress the retaining spring...

    JCB 525 Telehander - No foward drive

    Hi, I think it will be around 250kg as you suggest. Raise boom in the air with the bonnet attached. You may have a red u section piece on steel with the machine (ontop of right rear mud gaurd) which fits over the ram rod to prevent the boom from squashing you should something fail. There...

    JCB 525 Telehander - No foward drive

    Hi, Im affraid you are correct. Time to pull the box. I have made a cradle from some 12mm flat plate and some pieces of old box section that sits on my trolley jack to aid removal and replacement, just helps if im on my own in the workshop. Its also a good idea to reverse the machine onto...

    JCB 525 Telehander - No foward drive

    Hi, Thats the correct way to check the oil level. But running it for a min the dip will be ok rather than 10. Too much oil will not cause drive problems from cold. Its difficult to diagnose faults over the internet, all i can do is use my experience to help guide you... If you select a...

    JCB 525 Telehander - No foward drive

    Hi Colin, If it has stripped the splines there may not be debris in the bottom of the box. If its the clutch pack there will be debris. I see you have a workshop manual, the fwd clutch basket has a drive gear fasterned to it, The two are held together by a spline and then crimped so they...

    jcb 3cx problem

    Hi, The control valve would be the next place to look for scoring and general wear. How long does it take to drop?

    JCB 525 Telehander - No foward drive

    Hi, These can strip the splines which hold the drive gear onto the clutch basket. Normally happens when people go from fwd / rev without stopping. If the clutch plates have broken up the friction material will be in the strainer in the bottom of the gearbox.

    JCB 550 no 4-way stearing

    Yes the proximity sensors. They either go faulty or out of calibration due to wear in pins/bushes ect. There will be a 10A fuse for the steering system.

    JCB 550 no 4-way stearing

    Ignition on. If you hold a spanner on the bottom of the sensor you should see a LED light up close to where the wire is at the top of the sensor to show they are working. Check this 1st. With the axles in straight ahead position there will be a disk or peg that is directly under the sensor. The...
