Hi all, The lifts om my Crystal are playing up, I have no position control, i.e. lifts are either fully up or fully down. No middle ground. Also, when lifts are up, the relief valve is blowing off. I removed the lift cover & the 2 steel shock absorber plates mounted on the rear end of the...

Hi all, Just looking for a 2nd opinion before I go splitting my 8011. It is making a groaning noise when the PTO is turned on, and whenever the PTO comes under a heavy load. Also a vibration can be felt through the floor, just under your feet, at the same time. I have a feeling that it might...

Hi all, Just wondering if anyone can tell me if the valve seat inserts for a 12111 head can be used in a 12011 head. Some of my valve seats are worn & it would be cheaper to buy the ready to fit inserts than to get them made from scratch. Was there any difference in valve size, seating angles...

Hi, May be able to help you out. Pm me a contact no. Mark

Not so sure about the 6 cyl ones, but I know that there are different ones in the 4 cyl tractors. There is a difference @ the gearbox end of the shaft, depending on whether or not the tractor has an oil feed to the hollow shaft. The early type shaft is slightly shorter and cannot be replaced...

Not quite sure what you mean ???, but if you are talking about the hollow shaft, then the answer in no. This can only be removed by splitting @ the bellhousing, it can be a struggle to pull the hollow shaft from the hub, especially when the splines are badly worn. The shaft can lock into the...

Hi John, You don't waste any time !!;D Thats the beauty of these tractors, not too much to go wrong & easy to repair when they do. This is a fairly common thing on Ur2s especially ones that do a lot of PTO work. If you still have the tractor split, check the hub that the hollow shaft is...

Hi John, Sounds like the short drive shaft to your hydraulic pump has gone, it could also be the tripod in the clutch unit. If your torque & PTO are still working, the tripod is OK, and your pump driveshaft is gone, if they are gone as well as your hydraulics, then your tripod or hollow shaft...

Might be able to help you out, PM me your phone no. & I will give you a shout. Cheers Mark

Yeah, spot on. 5th gear high range.

Its possible that the clutch disk has rusted/stuck onto the flywheel. This can happen on vehicles that don't get used much. If you put the tractor into gear, and then start it with the clutch pedal pressed ( put the tractor into top gear ), this is usually enough to free it. You may have to...

You will find that cab on some 3511 and all 3611 models, as far as I am aware these are the only other models using the narrow cab. Hope that helps. Mark

Hi all, Has anybody got any experience adjusting the amount of fuel being delivered by the injector pump ? I think my 8011 is a tad overfuelled & I would like to try to turn it back a little. It has a 2478 pump & the spill timing has been checked & is spot on. I have tried adjusting the...

Haven't tried cleaning the switch, might give that a go. All flashers, brake lights, rear spotlamps & headlights are working, but no dips or front spots. Is there a relay that switches between the front spots & the dips ? Mabye that is the problem ?? Thanks Mark

Anyone have any idea if the spotlights & headlights are fused on a 2004 6341 super. I have tried all the fuses behind the dashboard side panel but they are Ok. Are there fuses hidden somewhere else ? Thanks Mark

Hi all, My steering has developed a strange fault & I'm hoping that somebody can help me figure it out. It is very heavy when turning left, but works fine when turning right. Oil level is OK , and I have changed the valve at the end of the steering piston (behind the end plate ) for a known...

Hi........ Success !!! I swapped injector pumps today & tried the "lazy" 8011 on the Dyno again. With the injector pump swapped & NO other changes the PTO HP is now a steady 78. Looks like a little diesel goes a long way :D Thanks Mark

Hi All, Just wondering what the correct PTO HP for a 1978/79 8011 is ? I have 2 Crystals with exactly the same engine (8001) & the same injector pump (2478 ) & I put both of them on a Dyno tester today (see video on YouTube ;)) and there is a massive difference between the two tractors. My...

Thanks Renze. Is this C-pin internal ? The lever looks to be working from outside, I assume I will have to lift the gearbox lid ? Mark

Hi All, Has anyone got a parts diagram for the high/low range lever and selector for a 2004 6341 ? A friend of mine is having difficulty engaging the low range on his tractor. I had a look at it today & the lever is working OK outside the gearbox housing & I was wondering if the 6341 has a...
