keithjh Posted April 12, 2008 Share Posted April 12, 2008 Hi All, Am just about ready to fit a new Turbo to the 300Tdi, how do i prime it with oil?, or is it just a case of turning ther lump over without allowing it to start.

SiWhite Posted April 12, 2008 Share Posted April 12, 2008 If it were me, I'd fill up the lines with oil before connecting the turbo-end unions (clearly, fit the engine unions first, otherwise it'll all drip out ) Fit the bottom turbo union first, then fill the turbo through the top union hole, then fit that union. Then, I'd turn then engine over forr 10 seconds without letting it fire (undo the fuel stop soleniod wire) before starting it properly.

western Posted April 12, 2008 Share Posted April 12, 2008 fit it to the engine, connect the return line & fill from the feed line connection, then rotate the turbo by hand to allow some oil to get around the shaft, then reconnect the feed line & start the engine & check for any leakage.

JST Posted April 12, 2008 Share Posted April 12, 2008 i dare say thats the right way to do it but i didnt prime mine when i changed it! no problems yet 45k ago Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted April 12, 2008 Share Posted April 12, 2008 When i did some REME stuff, for the bedford MJ you had to remove the top pipe and pour 1/2 a pint of oil in to prime the turbo. wouldn't hurt to do a similar thing with the Tdi. i've done it before with several squirts from an oil can.

foxminer Posted April 12, 2008 Share Posted April 12, 2008 I wish i asked this question before fitting my recon turbo a few months ago which is now an expensive piece of scrap. Foxminer. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted April 12, 2008 Share Posted April 12, 2008 I always find a good coat of red oxide works wonders ... Mo Quote Link to comment Share on other sites More sharing options...

newclear Posted April 13, 2008 Share Posted April 13, 2008 Is this priming just for new/recon'd Turbo's? Hope So Matt2 Quote Link to comment Share on other sites More sharing options...
RRX Posted April 13, 2008 Share Posted April 13, 2008 You should prime any new turbo or one that's been sat off an engine for a while. Disconnect the fuel stop solenoid and turn the engine over for 5 - 10 secs until the oil pressure warning light has gone out. Then start the engine.

Peaklander Posted August 24, 2018 Share Posted August 24, 2018 (edited) I thought I'd add to this thread based on instructions I got with my recon 300TDi turbo. Simplified, they read as follows. 1. Don't connect the oil pipes 2. Engine oil change and fill the new filter before fitting 3. Manually add oil to the turbo oil feed port and spin the blades by hand to coat the bearings, top up more if possible 4.Remove connection to stop solenoid and crank engine for 10s, catching oil from the top of the feed pipe. Let starter cool off if necessary 5. Crank again for 10s and continue until plenty oil flows, then connect feed pipe to port on turbo with banjo and copper washers 6. Now crank again and catch oil from oil drain. I was told that the flow is about 300ml per minute so there should be a reasonable quantity in 10s 7. Re-connect oil drain. Don't do what I did and disconnect the bottom end, as it's too hard to get in there. It's better to reconnect at the two bolts and gasket under the turbo The instructions expressly state not to crank until the oil pressure light has gone out as that's not a reliable indicator or good oil flow through the turbo I hope this is OK. Please correct me if necessary. It's what I have read, not what "I know". I have had to follow the turbo people's instructions to be sure I don't damage the new one. They are pricey after all.
