Purpose Built Forwarder Thread (OSA, FMG/Bruunett, Entracon, Norcar/Logset etc)

Sorted the spool valve problem, needed a bit of adjustment on the servos.Wiring is in good condition, it had a full new wiring loom when it was rebuilt, Noticed yesterday it,s had it,s timber bunks widened by about 9 inches each side.You can see on the headboard and the doglegs on the bolsters. Now the pressure is off the Bruunett, going to fit a new radiator and oil cooler.The Bruunett is a lot happier not having to lift the big saw logs.

Be interested to know where you sourced the oil cooler for the 578

[elfinwood saws]

TCD, got a re,cond oil cool for 40 quid, the cooler had been left for repair 2 years a go and the customer never returned to pick it up, so i got it, it,s off some sort of access platform. Just got a new radiator as well, off ebay £154 delivered:thumbup:

did the harvester head get sold in the end as its back on ebay with your original picture for more!!

[elfinwood saws]

Logrover, yes the head sold, it went to Slovenia, just had a look on ebay and could not see the head.

Hmmm, next Bruunett problem? Either doesn't like the heat or is the engine oil pump on the way out? Always shows flickering low oil pressure at tickover when warmed up but now exhibiting the same when even revving as high as 1500 rpm + ; granted it's working up and down a decent slope. Switch it off for 5 mins and the light goes out at startup but prob returns soon enough. Topped up the oil - seemed to help - for 10 minutes!

 

Or could be inj pump shaft seal seal as level might be going up i.e. diesel in crankcase...

[Wood wasp]

At a guess I'd say pump. We had crane that worked fine till oil got hot and thin then it wouldn't lift perform as it should but switch off and cool meant it would work fine again - a new pump resolved issue completely.

TCD, try fitting a pressure gauge, to check the pressure, maybe a faulty pressure switch, or maybe bigends and or oilpump.

TBH I trust the pressure switch, esp. since it goes off after a 5 minute rest / cooldown. Might be blocked filter / pump strainer due to using newer detergent oil which has loosened crap. I've just been reading the horror stories about main bearings and / oil pump. What could be a moderately easy job is a complete heahache because the oil pan is integral with the frame of the machine... Not what I need right now, just spent thousands on the hydraulics, time to leave it in the yard? Did you have those Ponsse details? Thx

our osa does the same with the oil pressure light but seems to run sweet, oil level good, not checked the sender though.
