New to me 79 FJ45

[nicholas]

You can only run 45-50mph with a 2F/4-speed something is wrong, and a 5-speed won’t fix that. You should be able to cruise at least 70mph as-is if it’s running correctly.

Good to know, I’ve always heard that the 2F is on the slower slide. I don’t have a functioning temperature gauge and it didn’t come with a tachometer so I haven’t felt comfortable, pushing it. According to this thread, it sounds like the 2F will scream pretty loud, but it can handle it. I just need to get the temperature gauge./sending unit fixed and some sort of tachometer so I can monitor things before I push it.

FJ40 max cruising speed

I've got a 76 FJ40 stock 2F and 4 speed tranny. It has well worn 31" tires and I'm assuming stock 4.11 gears in the diffs. Going by seat of the pants, the 2F just doesn't sound or feel like it wants to go over 45mph. In other words, if I had a 5th gear I'd be shifting at the 40 - 45 mph...

Those tires look to be around 31”, not sure what axles gears you have but they’re either 4.11 or 3.70

do a good baseline of your cooling system
And you can run at 3000-3200rpm all day.

Thanks I appreciate it! Yes, it appears there are roughly 31s. They stand about 30 inches tall. I’ll definitely go through the cooling system and get it baselined. The radiator that’s in. It seems to be decent condition and doesn’t have any leaks so I may just keep that and flush it.

It looks like this transfer case is new or rebuilt unit. However, it looks like they just took off the speedometer housing and slapped it on and didn’t replace the output shaft seal in the speedometer housing as it feels old and crusty. So I think that’s where it’s been leaking. There also wasn’t a seal between the speedometer housing and the transfer case but I haven’t looked at the parts diagram to see if there is a seal there. I’ll add the output shaft seal to the Cruiser outfitters order.

The rear corner glass and rear rectangle glass is all scratched with deep splatters, it appears to be damaged from welding slag.

Has anybody had any luck, sourcing rear corner glass or rear panel glass? Seems to be unobtainable now. I’m not sure what the reproduction aqualu 45s are using but it seems like nobody in the states stocks the rear glass.

I found some out of China for a reasonable price of $300 for the three pieces but they want $1700 to ship it.

I wouldn’t trust anything from China these days. The center glass is flat and can be locally sourced from any glass shop, using your existing unit as a pattern. Look to the Middle East for the corner pieces.

post a wanted in the 45 classifieds, there are some used ones around.
they are 45 specific and left and right sided

x2 on rear glass, any decent auto glass shop can cut the flat glass

they have free shipping from their US based wesbite. Showing sold out right now. I am curious how well their corner glass fits.

I have to look up their US based website and check it out. I’d be curious to try for the price.
