1971 JCB 3c MKII Servicing and Renovation

[essexpete]

I think that the 1970 Mk 11 we had simply had a very similar cap to the typical rocker cover oil cap. The actual latching part of the cap was the same as a rad cap. The later Mk 111 had an external filler in front of the windscreen off the bulkhead. That was quite a nice chrome job.

I'm in the same boat MrF, currently using a rubber glove as a fuel cap!

If you could take a shot with a ruler like you said we might be able to source a replacement.

It'll have to be ACS's ruler now sorry as its on its way to the UK!

My mk3 is/was a plastic moulded thing with steel innards located where you describe. The sun and vibration has ruined the plastic bit a long time ago and it went missing, but the metal innards is still there doing the job for now.
If anyone is missing the 4/98 engine oil cap or a leg has fell off like they often do, the land rover series 2/2a 3 leg caps is the same fitment but with ears on to make it easier to twist on/off, and lots easier/cheaper to find new...

Never heard the filler cap called a leg cap before!

Your welcome, just glad that some of that poor old 3c2's gone on to help improve someone else's machine rather than just my own.

Does anyone know the length of the hoses that go from the control valves out to the backhoe, I'm guessing about 1,5 to 2m each?

several of mine have split rubber outers and having just done all the hydraulic fluid and filter I can't afford to lose a load more hydraulic fluid.
I'm already using my blanking caps as the bucket ram blew a hose.....so now I'm thinking it's best to replace all the ones that I can see look bad

Thanks

The best way is to take one of your hoses off and with you to the local supplier of hoses and have them made up. They will like you extra much and be more helpful if you clean it before taking it also and getting the stores bod onside that does them is a definite advantage for us. It might be quite expensive to replace all of them in one go if prices are anything like they are here (70 euros for a new hose seems about average) and there are also separate ones inside the boom and spanning all the joints that you cant see easily.
Obviously if one is really damaged looking then pre-emptively changing it would be good insurance but popping a hose seems a common thing on old machines. If you shut down and fix it the oil loss shouldn't be too bad depending on which system its in but its more the inconvenience of being deep into a job and having to stop to go get parts or worse it blowing on a sat afternoon and having to wait until monday. I've often sent my wife with the blown culprit in a bag for me if the shops open while I did a bit of machine fettling while it was down.
