Interested to hear the welsh cowboy grows the waky baccy-that sort of explains the weird behavior!!!!!!

Our fella was running the engines up to check on a few things and top up with coolent-old boy up the lane couldn't understand the racket,sounded like the end of the world apparently, so he told the wife to drive in the opposite direction in case anything would happen. Funny my hearing must be going cos even with the straight through pipes fitted the brute does not sound that loud-mind you with a mis-spent youth driving a Ford 5000 with safety cab the hearing wouldn't be that great either.

TC, there could be a couple things to check on all that smoke so check the air cleaners first & if ok check out the exhaust by-pass valve & if ok then break each fuel line one at a time with it running & see if the smoke clears when one is opened up along with the throttle.Also might check the valves & the compression releases.If all checks ok you might want to check the injection housing timing then.

Hi S.J. to see this D9G perform it will mean a trip for me of about 320 miles, this might not be a big distance in the U.S.A. but here it is the big "grid lock" if you hit any road at the peak time, so I would leave my shack at about 4.30 am. and hope to be done ready to set off for home by 6/7 pm, any help I am always glad of, my first thoughts was the fuel/air ratio control,but the team on site say it all works as it should??????, any how its been a convert to direct electric start they tell me also having a new turbo fitted about 2 years ago, the exhaust by-pass valve I am not sure if this is fitted to this tractor????, I think the exhaust gas leaves the turbo via an elbow then straight up the stack past the dust ejector, I have not seen one of these bypass valves, anyhow does anyone know what sort of air pressure I should be getting at full load (stall) from this turbo, also I may be giving it a Birthday and changing the oil /filters on the poor old banger,so I will be checking the turbo oil bypass control valve if I can remember how to do it , I know it can get oily if you dont shut down fast enough with the oil line removed and one port only blanked off,
always happy tctractors.

There have been a couple of posts observing that the ACMOC board of directors has not come onto this thread and responded.

The board of directors is an overglorified name for a committee. We get together to discuss the club's operation and problems, and make decisions as a committee. We run the club. Our last meeting was in early January. Our next meeting is in March. In between, this post comes up. The board has not met, so we can't make any comments about it because we have not discussed it. OK, so you say, well, why doesn't some board member make his own comments? Maybe it isn't that no member of the board is interested in the topic - maybe it is not a priority for the individual member.

On the merits of the proposal to seek the manufacture of critical parts, I'd be delighted if Caterpillar would consider making a run of say, D2 undercarriage parts (chains, pads, etc.). I suspect they wouldn't consider it, for the reasons already expressed by such posters as OzDozer. Perhaps Berco or some other after-market supplier would be a more likely prospect.

I wonder, though, about why companies like Berco no longer fabricate those parts. Maybe there just isn't enough of a market for them. If they could still sell enough of them to make a profit, don't you think they would still do so??? I also wonder why "jawboning" by the club is thought to be beneficial. Aren't businessmen supposed to be smart enough to decide what products they can make a profit on?

I'll tell you what the board of directors is most concerned about. It is ensuring that we have good financial records so we know where the club's money is coming from and where it is going to, choosing where the next show is going to be held and ensuring it runs smoothly, getting the club's bulletin board straightened out, getting the chapters up and running smoothly with common goals, improving the newsletter (magazine), and running the model program to ensure profits to the club to keep the dues down.

Frankly, we have our hands full right now, and probably don't have the time and energy to devote to this new idea. But, after we get some things straightened out, maybe we could inquire about this.

TC, I don,t have specs for the D9 but the SN etc is needed to be exact, same for the exhaust by-pass as the early ones had it but I believe the late ones didn,t can,t remember, been away from them too long.Just in round figures I,d guess the boost would be (without a specs book) in the area of 16 to 18 lbs. but specs use inches of mercury which would be twice lbs. so would be 32 to 36 Hg. A rack setting book will have the boost specs in it if anyone has access to one but the couple I have are too old to cover later stuff except a couple OTR truck engine spec. books I have.

Hi SJ, TC,
You guys are the experts and I like to follow along and learn from these exercises:) I have the Service Manual for the D9G (66A1-up) (early). I was looking for the boost pressure which I could not find but under the turbo trouble shooting section (making smoke) the manual is big on checking fuel supply pressure (25 psi required) to operate both the exhaust by-pass valve and the pressure ratio controller which require a minimum of 18 - 20 psi. Also mentions a strainer at the fuel inlet to the exhaust by-pass valve that should be checked.

The combinations of turbo-charger arrangements is endless and would need specific identification to do any good in the rack setting charts. Be happy to post any info you need from the manuals.

George,

I appreciate your response to this question.

As you noted, the BoD may have their hands full resolving other issues currently, but I think that this issue would be worthy of future debate.

In the UK, we always struggle to build the membership base of the Chapter above 350 each year, in fact we lost nearly 1/3 of our members after the initial renewal cut off date at the end of January (we have now managed to recover nearly 50% of the lost members).

A common theme, is always explaining \ demonstrating the benefits of becoming a member of ACMOC, especially when the cost of shipping the US magazine is factored into the membership fee. Improving the US magazine will be a big step in the right direction, in addressing part of this problem.

If we could demostrate an added value of being an ACMOC member, i.e. by commercial partnerships \ alliances with 3rd parties as other similiar clubs & societies have in place, then this would also serve as a good incentive for prospective members to join ACMOC.

David is right,when we have tried to sign up new members the question that comes up every time from Cat owners is they want to know where to get spares,can the club help? the cost of membership is too high, also they want working events to go to, which are close to where they live due to high fuel costs in getting to events.The US magazine is not as good as the Chapter2 mag.We also need to get younger members to join.I guess our present members average age is around 55/60.We need to demonstrate to potential new members we can deliver what they ar looking for.
Another thing we are up against, is that people don't like getting their hands dirty these days.
Thanks GWH Diesel for your reply.

Also, forgot to add the clubs name.We are always asked we like to join but we don't own a Caterpillar machine.May be a name change?

Firstly David I have the ACMOC mag you are after, No 37 I have just finished reading it !!!!. if you are going to the Malvern Bash I could stick it in my pocket for you, I hope no one thinks I have a deal going with J. Moore . its just a good outfit to deal with + they stand by the parts they sell, + they are good at what they do, not once in 25/28 years have they mucked me about or robbed me.
On to the D9G, I do have service books for the G & H model tractors but I have not had a chance to peep inside the covers as I have been busy fitting a Tulsa winch, pipe work valve blocks rope and a Mckissoc??? hook block onto a new riggers boom truck, anyhow the D9 is waiting for me to give it a dose of Viagra, so any info on the exhaust by-pass unit or other good points I am more than thankfull to listen so dont stop there S.J. + Old Magnet, as I realy would like to get this old Bird Nailed (sorted) in one day , I will be taking a few snap-shots of things as things go on,
