Hi all, engine oil pump main feed pipe has no seal. Just metal to metal contact surfaces. Our serial number is 66a 5665. The later models seem to have seal as my parts book starts at 9000 ish and lists one. It does signify C for change. Has anyone come across this before? Thanks
Jonathon,I’ve just advertised a D9G parts book on Old Girls for free. Do you want me to check the serial numbers tomorrow as the parts book may be useful to you
That would be great. Thanks Nicky
There can't be too many 9s over there, any chance you've known this one at some point?
The attachment for the oil lines covers 66A tractors with Serial Numbers from 5449 to 6284, which includes yours. hopefully it contains the information for are looking for. Of course it only applies if the engine is original.
Thanks for that Nige! That confirms what I thought. No seal at all. They obviously thought it was a better idea to put one in the latter serial numbers.
The tube assembly 9M1009 was changed to 9S3201 and a 8M4986 seal was added at s/n 66A8576
That makes sense now. There were a lot of tractors built without the seal so it can’t of given to much trouble. Thanks for the help.
There’s still a few hidden about on these shores Shimmy,most of which aren’t on any any social media platforms.D8 Ump and myself have been known to share a few pints occasionally when we meet up.He has some very nice D8’s,but he’s known the D9G in question for some years although I’ve not seen the beast myself.
Interesting Nicky and D8 and with a territory population of ?100M and about the size of Victoria [an Australian State], what brands dominated the large machine landscape? Leibherr, Oliver, Fiat/Allis, Euclid, Hanomag as guesses?
It all depends in which era you are talking about, what product line (track-type tractors, wheel loaders, motor scrapers, etc) and lastly what size of machine. Each combination will produce different answers. !970s & 1980s for example and large machines. Track-type tractors - Cat/Komatsu; Motor scrapers Cat/Terex/Le Tourneau; Wheel loaders - Cat/Michigan. Off-highway trucks - Cat/Terex/Wabco/Unit Rig.
There‘s a D9g on a youtube channel called Mr Hewes, military tanks trucks etc. Very interesting, cheers
That’s correct. Me Hewes purchased the tractor from a quarry in Northumberland after I sold them a D8N and a D9R making the said D9G redundant. It’s a decent old D9G
As Nige says,depends on the era. I started working in the late 80’s where there were a mix of Cat and Komatsu tractors in the large category,Terex and Cat scrapers and Cat and Terex in the rigid truck department,although there were a handful of Lectra Haul,Euclid and Aveling Bardford rigid dumpers knocking around. Excavators were much more mixed with Cat,Komatsu,Liebherr,Ackerman,O&K,Demag and every far eastern effort you can think of. Not forgetting the JCB brigade. These days,although Komatsu supply many small to midsize dozers,you’d be hard pushed to find big ones.They seemed to have lost their crown in the 155 size and above.Cat have the D8,D9,D10 job sown up all though a D475 does work in a Scottish silica sand pit. Scrapers are Cat only
