Well it seems my D9G with all your help is one hell of a machine.  The old owner had some guy show up at my house and wanted to buy her back!  I was proud of what we meaning the forum has done and showed her off... She fired right off!!! Been sitting for 4 months and bam she ignited and came alive!!! The guy even brought a mechanic out to check her out... The mechanic an old memeber here on forum named Spike has a deep love for old iron like many of us do said she is one hell of a machine..... Well needless to say the guy was really insistant I sell her.... I thought about it because the old owner needs if but I cant let her go!!! Not after all that damn work to get her properly sorted out!....   I am in love.... Crazy... Never got around to giving her a paint job....


 I need to replace the old generator with an alternator as could never get it straightened out.... Of course I am nervous about her finals and the transmission.. Replaced all fluids and cleaned the screens... Any advice guys on the finals and tranny?  She spins good brakes good but just of corse a little nervous on a 50 year old machine... But she is tought!   Sorry I was gone for so long just got caught up with life her in Hawaii

Hey! Great to hear from you, been wondering how things were. No dont sell it! hire it out, tell him you'll do the job for him, make some money with it. Keep an eye on the screens and magnetic plugs on the finals, keep the right oil in them.

That is a great feeling, to have one rise from the dead! Amazing how they are more desirable when they run too! Keep us posted with your tropical adventure. Thx. JM

Not sure I like the new site!  Looks good though!  Yeah this guy would not take no for an answer!  Anyway, I need to sort out the alternator/generator!  I never got around to doing the finals!  I will make sure I do them next!  No leaks on the old girl now I am sure you remember I did a ton on the old girl.  I am going to take some pics of her.... Put it as my pic on my profile... Happy New Year!  Talk soon! George 

Those D9 finals can be a challenge, not like your basic D7G finals.

aloha George....i second Neil, and third Rome's suggestions!

it is a great feeling to rescue these machines and bring them back to glory...i don't understand guys that won't repair or do maintenance to keep them running properly but yet want a dozer??

Hi, gvanhouten.
If you are at all nervous about the final drives - or any oil compartment - take some oil samples and have them analyzed by your Cat dealer. They do like to know the brand and type of oil that was put in the particular compartment to give them a base line but they can tell you pretty much everything that is going on in that compartment from the sample.

And I third the earlier suggestions - wet hire the old girl back to these people. I would not want to sell it now either.

Just my 0.02.

Great hearing from you guys!  You have to remember where I am.  Its not like its cheap to transport a D9 from California to Hawaii... I am not sure on freight but crazy price like $30,000.   Needless to say no way would I let the previous owner rent it from me!  It took me 6 months and alot of crap to get her back... Besides I dont think any of us wants to hear me again... LOL.  I was hoping to get to one of the shows but because of covid well we know how that went.... I have a great wife and she said no way is that dozer going anywhere!  We sacraficed to much.... You buy something else and your right back where you started... She is right... 

I will take the sample from the transmission and the finals to cat and get them analized...  I am no cowboy on her I try to  be smooth and steady.... I fix it so I respect it.... Cant wait to chat more...Any ideas on the alternator?   Remember Generator is on her now was benched tested and passed... Replaced the regulator and flashed it and never charged the batteries... Not sure on what next to do.... I will figure it out as we always do!  Talk to you guys soon... I dont want to 

What type generator do you have. Type A (Delco Remy) or type B (American Bosch).
They have a different polarizing procedure.
If you wish to go alternator, gear drive is preferred.

I don't recall your s/n but I believe it should already have a 24 volt belt drive alternator.
