Cylinder seals replacement JCB 3C3

Hello there, I thought i would share my little experience in changing the seals. It's definitely not as hard as I thought initially. So I first ordered this seal kit from VicaryPlants https://www.ebay.fr/itm/153238849986 As far as I'm concerned, all the big cylinders are the same on the 3c3. The har...

Homemade simple wood splitter for JCB 3C3

Hi, it's been a while since my last post but the old lady is still running great. During that time I managed to get a bigger property with some wood on it. I built that splitter attachment with a 180 steel beam and 10mm plate both bought at the local scrapyard. (Managed to find a grading bucket too ...

Re: JCB 3C MKIII /5 picts and questions

Hi everyone, Yesterday I realized I had a blow by problem. Lots of oil leaking by the rocker cover vent. The problem was simply a wrong dipstick ! I think I had 25 Liters instead of ~10 :roll: I found the original dipstick laying in the cab with the cap missing. I repaired it but can anyone confirm ...

Re: JCB 3C MKIII /5 picts and questions

Hi, today I managed to replace the crankshaft front seal. To do that I had to first grind the 38mm socket. I smoked my grinding wheel ...

Re: JCB 3C MKIII /5 picts and questions

Hi, that is true there is a strainer at the bottom but I don't really want to drain all the tank maybe one day ahah. I did not made any progress since the last message. I'm waiting for a 38mm socket in order to remove the front crankshaft bolt. Is tightening the bolt with an impact wrench "good...

Re: JCB 3C MKIII /5 picts and questions

Thanks, The video was taken when the engine was hot so I think pressure is normal after reading your story :) I guess I just have shitty seals. Today i fixed a bucket under it as a temporary fix.

Re: JCB 3C MKIII /5 picts and questions

Re: JCB 3C MKIII /5 picts and questions

I reckon when you have stood it for a while it may be worth carefully taking bung out of bottom of the hyd tank to see if there is any water in there? Yes definitely, you just have to gently unscrew the main big bolt a bit until liquid slowly coming out of the threads. In my case water. Then tighte...
