MJB1 Posted September 26, 2009 Share Posted September 26, 2009 great pics gav , the new grader looks well kept for it's age , real shame it'll be stored outside but sprayed over with diesel/oil mix it shouldn't start ageing overnight ! i used to dread harvesting in the dust , apart from brused potatoes,you at least knew what you'de be doing out of season ..................... replaceing many of the bearings due to dustgrinding especially for the main web agitators , well your luckier than i was, as i then had to get the harvester reconfigured for parsnips Quote Link to comment Share on other sites More sharing options...

Gav836 Posted September 26, 2009 Author Share Posted September 26, 2009 Here's a few pictures from today, the flat screen monitor shows the cleaning table and the other one is on the elevator for seeing into trailers and where the backs of them are This is the business end of the harvester, these 2 pairs of piggy back pumps circulate the 400 litres of oil round the machine to where its required. It was the mounting flange on the pair in the second picture which blew apart last night and has already cracked again as you can see in the last picture \ Quote Link to comment Share on other sites More sharing options...

Gav836 Posted September 27, 2009 Author Share Posted September 27, 2009 We think the bearings are on the way out in the main gearbox that drives the pumps allowing some movement and vibration on the shaft, will know more tomorrow morning when we have an investigation into it Quote Link to comment Share on other sites More sharing options...

Gav836 Posted September 27, 2009 Author Share Posted September 27, 2009 We can't do that as it would then start to leak oil from the gearbox so its getting an internal investigation tomorrow Quote Link to comment Share on other sites More sharing options...
Gav836 Posted September 28, 2009 Author Share Posted September 28, 2009 Here's some pictures of the cracked flanges, bottom flange was the first one where it blew the pump clean off the gearbox. Other two pics are the cause of the flange problem, the old pump had a damaged shaft on it and possible internal fault so I had a trip to Ely today to get a new one, spent 4 hours fitting it this afternoon, several pipes to be swapped over with a mixture of metric and imperial fittings Quote Link to comment Share on other sites More sharing options...
Gav836 Posted October 1, 2009 Author Share Posted October 1, 2009 A few more pics for you from the past couple of days, switched the grader round to start putting our other variety of spuds into our store at the farm so we could keep lifting while they sort the box store out for us. Another good load leaves the field And what happens when the irrigator only finishes putting an inch of water on 4 hours before we want to lift the field, had to abandon it until tomorrow Quote Link to comment Share on other sites More sharing options...
Smithy140 Posted October 1, 2009 Share Posted October 1, 2009 blimey that pump was abit of a mess mate. god to see you have it going again though. i'm suprised you didnt get stuck with your rowcrops Quote Link to comment Share on other sites More sharing options...
Gav836 Posted October 1, 2009 Author Share Posted October 1, 2009 We don't actually know what is wrong with that pump other than a damaged shaft, only looks a mess as I had to remove 8 or 9 hoses and one valve off it to refit to the new one My row crops are 16 inches wide and the harvester has a powered axle, came close to getting stuck a few times but the harvester kept pushing me Quote Link to comment Share on other sites More sharing options...
Smithy140 Posted October 1, 2009 Share Posted October 1, 2009 oh well not too small then. you got little chance of getting stcuk with 6 wheel drive then. sorry i meant the flanges look a mess \ Quote Link to comment Share on other sites More sharing options...
Gav836 Posted October 1, 2009 Author Share Posted October 1, 2009 Yeah they were a mess. Have since been told the actual price of the pump.......glad I was sitting down as its a good chunk of what the harvester is worth :o Quote Link to comment Share on other sites More sharing options...

MODELFARMER Posted October 2, 2009 Share Posted October 2, 2009 how old is the harvester? surely there must be some comeback as the internals of the pump can't exactly be damaged by you using it so must be a weekness in the pump?? Quote Link to comment Share on other sites More sharing options...
Gav836 Posted October 4, 2009 Author Share Posted October 4, 2009 nice gav have you still got the student? Well he worked yesterday...........got quite a bit of damage to repair to a trailer apparently Just had an interesting call off my boss though, sudden sense of relief at the minute Ricky, harvester is 10 years old and lifted approx 500 acres a year for its first 5-6 years so won't be any come back on it now Quote Link to comment Share on other sites More sharing options...

Gav836 Posted October 4, 2009 Author Share Posted October 4, 2009 They were moving barley from the potato store to the corn store yesterday apparently he's bent the pipe rack over on the trailer, ripped the brake pipe off the axle and the tailboard hoses are ripped off, he reckons they caught on the lift arms when turning............what a load of ballcocks, must think we fell off the last banana boat Quote Link to comment Share on other sites More sharing options...
