Wow that SOB looks nice. I like it. Its a nice narrow gauge. Would like it to be at my place! Hows it run?

Hi Bob, The machines motor was rebuilt 15 years or so ago then parked in a shed ,until a mate of ours bought it ,then needed money and sold it to us .Seems to run fine but seems to lack power .Will give it a fuel fiter change and some new fuel and with a good run pushing a bit of dirt around hopefully will improve. Have not had much to do with olivers  and all the ones our oliver mad friend has had i have never had a chance to operate. My son and myself have a cat d2 4u ,d4 7u,fowler Vf ,david brown 30 TD,2 trackmarshall 55 s,fiat 70ci,case 420c and a komatsu d50-15a. The fowler is a single cylinder 2 stroke diesel,and the david brown is one of only 600 made. Can post some photos if anyone is interested . ian.

Wwe always like to see pictures of a good tractor and even some bad ones. I had my AD running after painting it and my dad thought the timing sounded slow. Sure enough it was. I advanced it alot and now it starts better and has more power. I have ran it quite a bit since the overhaul and the engine is getting broken in nicely. Even more power! Got the junk cleaned out of the tank and filters and better yet. Lots of Black smoke! It'll take a little to get it broke in to have good power.

HI Bob,I will post some photos in the other crawlers section.ian.

I have an Oliver ad and my tracks won't stay on.  Does anybody know where to find parts for it so if somebody buys it I can send them in the right dierction

I have an undercarriage I would consider selling for the right price.

Bob

Bob,

Do you have a spare engine or parts to sell? I bought my AD not running and found one cylinder was broken out when I removed the head. There is about a 6" hole in the bore casting so it cant be sleeved.

Thanks, John

I have another block with some small cracks and holes. I think a guy could sleeve this one and be OK. If you are interested PM me and I'll call you.

Hi Blake,Was able to watch the videos .Thank you ,very good .ian.

Hi Guys , WE are having trouble finding a water pump seal  for our AD here in australia ..Does anyone know where we would be able to buy one ,and an email address to contact them on .Thanks ian.

I'll make a call Monday and see what I can find. I got thinking about your power issue with your AD. I think if I were you I would check the timing. Mine ran ok at first and I messed with the timing and it ran a whole lot better. Good luck.

Bob

Hi Bob , Thank you .None of the Bearing and seal places want to know about it over here . Thinking the fully rebuilt motor story was not real true .My son says once it gets up to operating temp the oil presssure drops to almost nothing .. Does the water pump interchange with any of the other models ?BD for example . ian.

That sucks when people have to lie or stretch the truth. I think one off a BD might fit, except for the thru shaft for the generator. I think one off an OC12 will work. I'll find out what I can and let you know what I find.

This is very common with these engines and not too worrisome. All you need is about 5 psi. The main goal is that the oil is circulating.

Blake

I was thinking about my AD today about the oil psi too. I ran it hard at a show over the summer and it was down to 15 psi at a higher rpm and like 7 ish at an idle. I know for sure the bottom is tight. There is a place on the filter housing where you can adjust the oil psi. I never have, but know you can.

I checked on that seal with no luck. I have heard that Zimmerman's is rebuilding them, so they must have figured a way to fix them. I would try them. I haven't had a chance to call about it, but will try next week.

Bob

Hi Bob, A cletrac mad mate who is also a fitter and turner  created one out of oil impregnated plastic .We have not put it back together yet to see if it was successfull as yet.If it works I shall find out the name of the material he used and let you know..Fingers crossed that it works. ian.

That would be good if it worked. I know it would help alot of people out on their water pump prediciments.

Hi Bob ,Well the water pump is back together and so far not leaking..Next time i see my mate i will get info on what the material was that he used .And what he had to do to make it..  Thanks for the help you have  given so far .These forums make keeping these tractors going a much easyer job .ian .

did you sort the power out on this AD ?

any news on the water pump seal construction?

nice looking unit btw.  

I'm thinking you should check the timing on your AD. I think that could be your problem. The timing chain stretches and can change the timing just enough to make a difference.

Hi Insissor ,Mate to be honest with you not really sure if it is a power problem . These tractors are a little higher geared than we are used to .So it may have been a case of expecting too much ..  So Where about in queensland are you ?   .    Bob the seal seems to be holding up all right ,but we have not run it very much .It seems to have been raining here for weeks ,so not getting much play time on them . Did ask my mate what materal he used ,but it went in one ear and out the other . I don't see a lot of him ,but i will make a point of retaning the info next time I see him ..He Made it on a cnc lathe so once Some one makes the first one it should be reasonable simple to keep making more .. He does drop in and vist the forum occasinally . So Scotty if you see this before i see you Put bob out of his misery and let him know what you used > Ian .

I'd like to pull my AD on a weight transfer against a bare D2 and a bare TD6 of the same vintage. I think it would be very interesting to see first hand on how they compair. I and alot of others who have been around my AD have been very impressed with the power it has. Maybe I'm partial because I'm a Cletrac man, but I think it does really good. I have an AG with an Anderson inside frame dozer on it and am actually fairly impressed with the power it has and its worn out. I've never pushed anything with my AD, but have pulled alot with it. I drug our Cat 15 (PV) around with it and the tracks don't turn on the 15. The 15 has a winch and I figure it must weigh in about the same.

I guess I've never ran too many D2s or D4s to really compair with the Cletracs either so...

Godwin Beach Qld but i have property at Coverty (near Proston)  :D

Hi Incissor , Now i know who i am talking to ,The ADs new owner .Allan is my son and the one you have been dealing with on Ebay .The OC6 is going to Tweed Heads .Whats is the ground like at proston , boggy? Allan has me talked into taking it down for you ,But the unloading part is the problem .Do you have any banks or cuttings on the side of the road to reduce the unloading height ?.Next problem is that if it fines up enough next week  I am going to be flat out trying to catch up on a big backlog of work . There is not going to be enough hours in the day and every ones is going to think their job is more important than every one elses .Ian .
