JCB 2D

Post #1 by DCL » Mon Nov 16, 2015 4:06 pm

Hello Guys,

I have owned an ex Manweb JCB 2D excavator for a few years and what a wonderful machine she is.

Unfortunately I lent it to my neighbour and whilst working the shaft from the hydraulic pump to the main crank pulley has failed taking the crank pulley with it and causing a leak on the hydraulic pump front seal. The hardie spicer at the pump end UJ seems to of given up and a small piece of the UJ casting has broken off as it fell to pieces.

I think I could probably fit a new hardie spicer, teh broken piece is small and at teh opersite end of teh ypoke to the circlip that holds teh spicer in, but I am unsure if I should replace the whole shaft to be safe?

If I can replace just the hardie spicer does anybody know what size, part number I would need or where I could buy one, nobody I have spoken to has any experience of the 2D?

If the whole shaft should be replaced does anybody know where I could get one or would one from another model machine fit, if so which model ?

Finally the leaky pump, is there a seal kit that I can purchase or would I be better taking it my local hydraulic specialist and let them strip it and fix it, last think I want is a pile of spring and seals when I take all the bolts out ?

Machine details from the plate are as follows:
JCB Machine Serial 2D 107979
Tractor Serial 384B 189418
Engine Serial 498NT/1792/20956

Advice here would be most helpful from anyone who has experienced this problem before, I have photos if needed.

Thanks in advance

Thanks Martyn I had already checked the manuals I had and the one linked doesn't help me any further, I really need someone with experience of the different machines who might know the differences between the models and the shaft configuration.

It might be helpful to find out if the drive shaft is similar/same as other models. Perhaps you could source a breaker and replace the ujs before installing?
