Barrus Shire Mechanic Cheshire

[Troyg]

Hi All,

 

I'm looking for recommendation for a Barrus Shire Mechanic in Cheshire, I am near Macclesfield. I do most work myself but this may be beyond me!

 

I am having hunting issues (revs up and down) with the engine (at low revs). All fine above around 1000rpm. I suspect I have a governer problem. Engine is a 4TNE88. All common things checked already such as filters etc. and injectors overhauled.

 

I have spoken with a local mechanic but he doesn't work on Barrus engines apart from basic servicing, so looking for someone who specialises in Barrus Shire. Or someone who is a good diesel mechanic that can deal with an issue such as this.

A good post :

 

Explaining what the problem is

Explaining what the make/model of engine is

Explaining what you have already tried

Explaining what information you need to move forward

 

It would be nice if others asking questions could do similar.

Do Barrus not have a local engineer? Most engine suppliers have someone who does their warranty work in an area.

Just a thought, the low revs hunting is not due to the alternator load coming on and off is it?

Not alternator load. For those unfamiliar with hunting, it is an engine surging (change of rpm) around every second. Engines can do this at cold but should vanish when warmed up.

Putting the engine under load (in gear) at low revs does worsen the problem. Occasionally this problem can disappear - but then comes back. Hence thinking perhaps a sticky governer. It's an engine problem, no problem with running gear. Biggest issue can be not being able to travel at tickover (low revs with load) as can make the hunting more evident. Removing the load can sometimes let the engine settle to smoother idling. Forgot to mention engine is manufactured around 2002, with around 1500 hours.

Warning - Pendant. Petrol engines hunt, diesels surge, but both are much the same but with different potential causes.

 

As said above, I wish all questions were like this one with all the info.

I think the TNE engine has very small coolant hoses running to a temperature controlled advance unit. The later TNV certainly does. A blocked hose will leave the engine running in "cold start" position.

Can anyone confirm?

It's also worth checking the spill (return to tank) pipework for damage/restriction. Has been known to create similar symptoms.

The coolant pipe thing may be a red herring, there are a lot of incorrectly labeled images on the web.
