Discussion:
Baker FJF-040 Brake Question

I just purchased a new project. This is an old military issue forklift.
72' Baker FJF-040 SN:73303
Pneumatic tires, flat head 4 cylinder Continental motor. I think it is in relatively good shape overall and I am having a fun time bringing it back to usefulness.

From reading the boards it looks like brake issues are rather common and that is the case for this machine. I took off the dual front tire. The tire is mounted to the secondary axle (or so I assume). There were a series of allen head bolt on the head of the axle and removing them freed up the break drum (free but still trapped by axle) but how do I get the axle out to work on the pads?

From the assy diagram available in the military manual it appears like the axle might be held on by a nut from the other side of the gear reducer housing but there is just a flat plate there with no nut. Maybe I just need to pull real hard? My only remaining option is to crack open the gear reducer housing by removing a series of bolts that go around its perimeter.

Before I do a forehead slap as I realize that I did it the wrong way I was hoping someone here has done this procedure before and can offer some advice. All brake advice would be appreciated (anyone with a service manual, even better)

BTW, when I freed the brake drum, redish fluid flowed out. It looked like automatic trans fluid to me but I'm no pro. Not sure if there is red brake fluid or maybe it was rust. Outside chance someone put the wrong fluid in the brakes.

Showing items 1 - 20 of 37 results.
The catalogs I found online were PDF as I recall. From there you only get part numbers. There were no dimensions. Sometimes I needed to use manuals for similar models because they might have had some parts that were the same.
Documentation for these forklifts is limited so may things are hard to figure out but of course you know that. Good luck.

Cheers,
Alan

Thanks for the answer!
Are the catalogs available as PDF?
Are dimensions / measurements given or "only" part numbers?

I was able to purchase a new seal for this forklift and was able to get rebuilt brake slave cylinders. Unfortunately I don't recall the name of the company I purchased the parts from. I used old military parts manuals to find part numbers and then searched the internet on those. The supplier was in the USA and the parts were not that expensive. Sorry I can't help more. I wish I recalled the name of the supplier.

Hello to USA! The German needs your help!
The brake drum on my BAKER FJF 340 402 is/was oily inside. Yesterday I disassembled to reseal. The oil seal is defective. - Please tell me what dimension has the sealing ring and where to order directly if necessary.

Another question about the brake system: Are there sources of supply for wheel brake cylinders?

Many thanks in advance,

Erik Schulze

I find it interesting have different these units can be. Mine has a solid dash with a tilt-up engine shroud but the one in the video does not.

I am not sure what to say about finding parts for the emergency brake. As bad as the brakes are on this model I do think that it would be good to have the backup. I think finding parts will be difficult. You could buy my truck if you are really into this, I have not sold it yet. Finding a scrap unit would be the other options but there are so many flavors of these trucks under the same model number, it is hard to know what you would be getting. Hopefully the brake parts are the same. I think they are from what I was seeing in the service manuals.

I was able to find pads and seals for my truck so maintenance items are still available. The emergency brake cables just actuate a mechanical linkage against the drum. If you don't have any of that, it will be tough to fabricate but not impossible.

The brakes on these units are so frustrating I could see someone taking maters into their own hands and trying to fabricate something better. The lack of a tightener for the drums is a huge frustration with this design. I could never get them to work as I expected.

Thought about a speedi sleeve kit, but I ended up turning the hub down to 4-7/8". The shaft did have a taper to it as well. Now both sides are identical so that they can use the same seal.
Yes, the wheel cylinders are right and left hand.
This is a video of the exact model I have:

It is most likely a Government issue truck. You can get a speedi sleeve kit to cover the grooves in the hub.
Are the wheel cylinders right and left hand? (The upper ports point in opposite directions)

Does the forklift have a 4 or 6 cylinder engine? Is it a Continental or Hercules engine? What are the tire sizes?

In September I purchased a FJF-040 (unknowingly at the time because the data plate was long gone) and through researching Baker forklifts came across this forum. It has been super helpful in tracking down the parts to replace the brake components.

I bought it knowing the brakes needed to be fixed, but this was before finding out the exact model I was dealing with. Replaced the master cylinder as that had an obvious leak, and tested out the wheel cylinders, which neither worked.

After taking apart the brake drum housing, the entire left side assembly was soaked in oil and gunk. There is also deep grooves in the axle housing where the seal sits between the drum and housing keeping back the fluid for the differential/final drive. The LH seal that had been installed was a lip seal that caused the aggressive grooves to form. LH wheel cylinder was leaking heavily into the housing. While the RH drive assembly was much drier, and the RH wheel cylinder was completely seized and gunked up. The backing plate on the RH side is wavy and bent up. RH seal is a proper oil bath seal and did not cause the same wear seen on the LH. Drive housing of the RH was turned down to 4.876, to what I assume would be to fix the grooves that the LH now has. Surface of the RH looks fine. All brake shoes have shims welded on to the bottom side of the shoe, it appears that the brakes were modified (I think the back plate bottom ends as well) as they do not look like what the manuals show.

After having everything apart, I noticed that there was no mechanism to engage the brake shoes with the hand brake. The entire hand brake mechanism just beyond the transmission is completely gone. No cables or hardware inside the drum housing.

My plan is to turn the LH drive housing down to 4.876 and replace both seals with 370195A (non-contact oil bath seal) that will prevent grooves from being worn on the housing surface. I will also be replacing the castle nuts as they are pretty chewed up from pliers and improper tools before my ownership. Beyond ordering the brake cylinders and shoes (looking like I will have to mod them), is there any place to source the hand brake components? The lever brake linkages in the drum. I would like to have the hand brake working for safety and parking, but looks like something I will have to fabricate myself.

I found that sometimes I had to use manual from different but similar models to get the info I needed. If your unit was used in the military, this link has a ton of free manuals for Baker. Hope it helps

Hello & thanks for the first answer!

Then my specific question: Where can I find manuals, operating instructions and spare parts lists on the Internet? - Probably the language barrier makes my search more difficult. - Please help me!

Regards,

Erik

Hi Erik,

Like you, I did not know much about these machines. I did find a lot of info online. My machine was used by the US military so they had documents online about how to service it, etc. Things like the engine are often used in other application so you can research what type of engine it has and then search for that specifically. I my case the engine in my machine was often used for welders.

There are also so excellent folks here with knowledge so you may luck out. The more specific the question, the more specific the help.

Good luck!

Hi Guys,

my name is erik. I recently owned a BAKER forklift, model FJF 340 402, built in 1974.

I think the forklift is great. The machine has not been moved for 10 years. I need pads, manuals and parts lists to get the vehicle back into operation. - Hence my request: Who can help me?

Thank you in advance, with best regards from Central Germany,

Erik

I think I figured out the bulk of my issue. Due to my own competence or the tilt of my driveway, I did not have enough fluid in the transmission. The way it was acting, this makes sense. It just did not have enough fluid to build pressure in the torque converter and I just got limp performance.

After fixing this I got better torque coupling though the transmission so now I could bog down the motor going up hills but I still could not get good performance up hills. It feels like it is geared too high. I don't think this machine (former Navy unit) has a creep mode on it and it definitely does not have the 2 speed option that some of these have. The result is that it really can't go up hills. Combined with the poor brakes it is not not good at going up or down hills. I don't blame the machine, it is just not made for that.

Unfortunately for me, hills is all I got on my properly and I have decided that this machine is just not going to work for me. After all the parts and work I put into it, I am going to sell it. I have it on Craiglist (San Diego) now. I am really disappointed though. There are so many things I could use this for. I was hoping this would be a low cost machine to solve my problems. I really like working on it. This machine is a tank!

Good luck!

Did you get your forklift driving better up your driveway? Mine doesn't do well up inclines either. Have to get a good running start of speed to have enough momentum to go up inclines.

Have the forklift facing up a hill (my driveway) and I can give the engine plenty of RPM. It moves up a little (6 inches) before it can't go any further. The engine is under load but does not stall so I think that confirms that the transmission is slipping. I am not sure if there are some models of this truck that were installed without inch mode but I tried to see if I got any better performance if I just barely let off the break (which activates the transmission). I did not see any difference. Maybe it is slipping before that could do any good.

I checked fluids and the dip stick seems to that this is full (inserted fully in) so it is not fluid level but as I mentioned, I think the wrong fluid was used. I will give Joseph Industries a call this week and see what they say. I am not sure if this is the behavior of a transmission that is worn out. It could be. I purchased this to fix up and use but am only now finding this issue and have no way to know if the transmission was good before I started.
