Turbo Actuator repairer recommendations

[rusty]

The actuator has broken for the variable geometry turbo on my JCB TM320S has broken. Fitter thought it most likely that the plastic gears inside had melted due to low coolant level. A new one from JCB is just over £1000 so thought I would investigate the repair route. Looking on line a repair should be under £200.
Can anyone recommend a turbo repair company that they have used for this type of work.

Its a Borg Warner turbo.

itsturbo 01132854922 leeds ish dont think you will get it repaired for £200 though

This will be interesting. I have a tractor with a turbo like that, and so far the actuator part have seized with 2000 hours intervals. The fix is always a change of the complete turbo/actuator package, which is usually about £1500 + labour. They never talked about fixing just the actuator, not even the first time when it was under warranty.

Hi Rusty, do you know the turbo model?, can give you another price for a new one if you would like. Cheers

Instead of fixing plastic gears in a turbo control unit, would it not be better to fit a dump valve and let the turbo run at full output all the time. The valve will run cooler as it can be fitted anywhere on the inlet manifold and cheaper to replace in the unlikely event of failure.
When you do find someone able or wiling to supply parts, the price will be that close to a replacement unit, it will I'd imagine be uneconomic.
If this idea takes off, main dealers would have to start fixing starters and alternators, even radiators, now we know that's not going to happen.

I know that some of the laptop tuners are working on changing these variable turbos with old fashioned ones and change the programming of the ecu to work without this adjusting. On mine at least, it's an "upgrade" when the engine was changed from tier 2 to tier 3.

Pity to change a perfectly good turbo just because of a failed controller.
Might be with considering just mechanically locking the actuator in full boost and let the dump valve do the rest?

 

[Serup]

I don't have any idea how any of this works, and will not be fiddling about on my own at any cost
And the "mechanics" just know how to change parts until it works

I have attached 2 pictures I took this morning. Hope these help. The engine was built in June 2013 and I think it is tier 3B

If anyone is going going to the expense of remapping a CR / Tier 3 or 4 engine then may as well do it properly;
- blank off any EGR recirculation, switch off EGR related functions in the ECU
- take out any other emissions related gubbins

Let the engine breathe properly, keep the ECU and ditch those phoney tuning boxes. Remap it once and do the job properly.

Better picture of the Turbo and a couple of the actuator

Thats about what i was told they where working on. No more egr, hot cooling systems, faulty actuators or worn regulator mechanisms inside turbos, more power and less fuel usage. I don't know anyone around here i would trust to do it properly, so mine is still stock and get a new turbo every 3 years

Cheers Rusty, had a good look for this turbo.... All the prices i have had back £1000 for a new one doesn't look bad money!

The actuator gears and motor may be available for this but are probably failed because the vanes are stuck

Gears and motor are usually less than £100

I had another investigation this afternoon.
When the ignition is turned on the (but engine not started) the actuator does a sweep OK which I believe it is supposed to do. When the engine is turned on and revved up it does not move apart from the odd brief movement up to the correct position then back off again. You can grab the arm and move it across manually and the engine sounds more powerful when this is done. This to me seems to suggest you may be correct with the sticking vanes as if the actuator internals were broken it would not do the initial sweep and sometimes move when the engine is running?

Send me the turbo number again the photo is not very clear ill see if the parts are available

With the engine off this morning the actuator arm moved freely. After this it actually worked OK for about half an hour and then the error code reappeared and the engine was down on power again.

Got the same issue here with a 2015 531 70, 3500 hours. Any chance of resurrecting this thread with your resolution Rusty

Paid a £1000 to JCB dealer for a new actuator which was simple for us to fit ourselves.
