Hi John, Do you have the E-mail adress to Nordjyllands Entrepenør service A/S ? I have a Fiat Allis 645-b (1975 mod) with Allison Allison TT 2421-1 transmission. I'm looking for a transmission charge pump and will check if they have one. regards, Hugo
Fiat Allis 645B Loader trans or converter problem I recently bought a FA 645B loader. I can run the machine for an hour or more until the torque converter temp rises in to the red area. The engine has to be reved high to make the machine dig and work. I changed the trans fluid and filter. I put Dexron trans fluid back in. The old filter was relatively clean with no metal parts or shavings. I've been told the torque converter was bad. I was wondering how the machine reacts with the charge pump bad? How big a job is it to change the converter? I have ordered all the manuals from SSB Tractor. Thanks for your help in advance.
tootlems, sorry my late reply..have not been in the forum fore a while. If the charge pump is bad the converter charge pressure will be low and you will have a slow moving and weak loader (converter slippage). Low main pressure will give low clutch apply pressure, causing converter slippage and overheating. In my case I lost all pressure and the loader would not move at all. What pressure does your transmission pressure gauge shows? I think it’s a big job to change the converter; you have to remove the engine before you can remove the converter from the loader. Here’s a picture of the dismantled charge pump, as you can see the bearing in the driven gear is gone. As a result the charge pump was not able to build pressure or create vacuum to suck oil from the converter sump. The reason for the charge pump damage is that the ball bearing for the accessory gear failed, (Pos no. 12) when the ball bearing failed it put all the stress on the small driven gear bearing. As I understand this is a common problem on this transmission. The ball bearing will now be replaced by a roller bearing.
I orderd a new pump and bearing from US Transmission New pump $675 (450 if if you send in the old core) Bearing: $143,54 As soon as the new bearing and pump was in the old loader worked as it was “ new ”again. Her it work as scaffolding
Nice scenery 512TR. Where in the Kingdom do you live? Your pickup is imported trough Drammen, but it doesen't look like Drammen on the pics! Liked your disasembley table too, and your old SVV dress.
Fiat Allis 645B wheel loader Thanks for the info 512. I have received the manuals that I ordered. I had a suspicion about the charge pump. If I remember correctly, the charge pump can be changed relatively easy from the side and underside of the machine. What is involved in changing the bearing that caused the pump failure. Does the trans have to be removed and disassembled or can it be replace while in the machine. Again, thanks for the help and the pics. They are most helpful.
tootlems, As you say, it is relative easy to remove the charge pump. It’s driven by the accessory gear witch also drive the hydraulic pump, first you have to remove the hydraulic pump. I did turn the loader all the way to the right, in order to get access to the trans/converter from the left hand side. That will give you the space needed to disconnect the pumps, it’s tight so you are limited to work with one hand at a time.:Banghead I also removed the air tank protection and airtank on the right side, to get some access/view from the right side. Before I started I did clean the top of the transmission with a high pressure cleaner. Also remember to drain the hydraulic tank before you start disconnecting the hydraulic pipes on the hydraulic pump. As soon you have removed the hydraulic pump and charge pump you will have access to the bearing. A good bearing puller will help you to remove the bearing. I modified an old cheap puller. When you should install the new bearing you have to heat the inner race in order to expand it before the bearing will enter the gear drive. Good luck
He,he.. MKTEF, I live fare up north, I small place called Gratangen.. in the middle of nowhere, but the nature is fantastic The Jeep Comanche was imported in the late 80's ..I do also have couple of Cherokees and a Wrangler

fiat 645-b transmission I've got two 654-b with transmission troubles. One has a two speed forward and reverse trans. that only seems to pull in high fwd and rev. Pressure is good in high but low in low gear. The second machine is older and has two fwd speeds and one reverse. It also only pulls in high gear and in reverse. What could this all mean? Can you pull the trans out the back with the motor or do you have to remove the cab?
I bought my manual on ebay for like $100.
Allis Chalmers 645b Hi John, do you have an 1969 Allis Chalmers 645 B please? regrds, DK
Have you got any Allis Chalmers 645 B pls? regards, DK
My charge pump is only showing 50 psi max. What should it be at??? Thanks
email me at [email protected] i can help u
Tt2421-1 I have the charge pump out on an Allison TT2421-1 trans as it was only showing 50-65 psi at any rpm range. Checked the main valve and doesn’t appear to be stuck either. Hoping the trans is not junk, but did find some metallic shavings in the bottom when I drained the system. I am waiting for the new charge pump and will reinstall and recheck pressures. I will keep you all updated.
According to the service manual the main pressure should be between 165-195 PSI, my trans fluid pressure gauge shows around 200 psi. After I changed the charge pump 2 years ago... the old loader have worked like a champ

Grease that poor machine!!!
i have bought a fiat allis 645b and when i checked it's transmission oil i found it had tellus oil insted of transmission oil, so i changed it's oil and filter, and when i started the machine from cold the gauge shows on red and even while working with the machine you fell the torque converter slippering. please can you tell me what is the problem?
Do you remember the part number of the new roller bearing in the transmission
This is 10 years ago Did check some old e-mails, the part no: 9438198 ( NDH 3L12 L) Ordered from US Transmissions, Inc. ( [email protected] ) After 10 years the transmission is still working 100% God luck
Thank you very much. I bought my 645 loader and put about 30 hrs on it and blew the same bearing as you. I thought i blew the tranny and was ready to pull it till i searched and found your posts on this forum. Thank you for all the info it was alot of help.
