1951 ford F2 swap in a NV4500 ? Anyone try it?

[skidmarks]

Bought a stock 51 ford F2 thats in fair shape. Off the road since 1974. Got it running and the motor is fair but the transmission had gotten water in it from a bad windshield gasket. Got it flushed out and broke loose but the spur gears have a lot of pitting. Before putting another non syncro 4 speed back in, i was thinking of something better. Its a F2 and i think a T5 from a S10 wont be a great choice if i wanted to haul anything with it. Has anyone adapted a NV4500 transmission to a 8 ba motor?

I made an adapter for a friend a couple of years ago. He is installing it in a '50 F5 Marmon-Herrington 4x4 conversion.



He doesn't have his truck running yet, but I believe the NV4500 is going to work out really well for him. He will have to build a crossmember for it also.

Thanks for the pictures. I made basically the same thing for another pu with a T5. Do you know off hand the years to look for for a 2wd NV4500? I dont know much about them but see a lot of cummins diesel guys love them.

Just wondering why a T5 wouldn't work? How much are planning to haul? The S10 was rated to pull (depending on rear end) up to something like #5500. The box capacity was kind of low but that probably had to do more with the suspension than anything else. I would think that the S10 T5 with the lower 1st gear would be fine for occasional light hauling.

If you used a '93-up S-10 T5, they are world class but have the Ford bolt pattern (ironically). Cornhuskers sells an adapter for them. They are also electronic speedo, but can be retrofitted for mechanical.

With your trans crossmember, there are a lot of potential donors. A T5 will not clear it completely.

A T5 doesnt have a provision for a PTO. mine is a F2 and has a different transmission crossmember with a lot of clearance and looks like it will clear a NV4500 . Just have to ad another flat crossmember a little bit behind it to support the NV4500.

Have already done the T5 behind a flathead in a couple other cars. Its just like when inwas asked why i wanted to put a 226H in a 41 ford pu, because ivd already have plenty of V8 stuff, time for something new.

I would leave the 4 speed in this truck but it got damaged from water. This 52 is all original and runs good. Body is fair. Good for a work truck.

Thank you for the link. Looks like its about 100lb heavier then the 4 speed

[willowbilly3]

I think the one the guys like to use on the newer Fords is from a gas Dodge

[expavr]

From the photo it looks like the shift tower will sit pretty far back in the cab. Any issues with the shifter interfering with the seat or its support?

The T170 3-speed with 4th gear overdrive isn't a real heavy duty trans but may work OK if a person takes it easy. It's a bit lighter and smaller than the New Venture design. The 1st gear on most truck transmissions are low granny crawler speed so a lot of folks don't use 1st as much anyway. The NV4500 is definitely heavy duty but you have to take care of those composite synchros by using the correct lube for them.

I can not offer any help on the swap, but I will give a positive vote for the 2wd NV4500 trans. I put one in my older transport truck (1974 GMC dually) & delivered customers cars all over the country with it to the tune of 400,000 miles on the first one. I then bought a Jasper rebuild & only put 30,000 on it before retiring the truck! Great Trans!

I believe the NV4500 would be a great transmission for an F2 and larger truck that will be used as a truck. You would have granny or compound for starting with a load and overdrive for highway driving. The transmission my friend is using and the one I have in the shop for a pattern are both from GM trucks. I believe he did some research and determined that the GM transmission would best suit his application. I can check the weight, but I don't think the NV4500 is 100lbs heavier than the T9 spur gear 4-speed.

Skidmarks, I weighed the T9 and NV4500 transmissions today and I stand corrected. The T9 weighs 120 lbs. and the NV4500 210 lbs. Add the adapter plate and the T9 transmission halfbell and you could probably add another 25 lbs. Considering the truck and it's intended use, I personally wouldn't be concerned about the extra weight. I believe the transmissions advantages would far exceed the disadvantage of the extra weight.

Syncronized and overdrive do far out weigh the difference in weight. Just keep it down to two fat chicks and ill be fine

[skidmarks]

Wasn't there a syncronized 4 speed available in 1952 only? Another option i thought was to keep the 4 speed and change the rear to a dana 60 with a higher gear.

Too bad the ZF 5 speed ford transmission has a built in bell housing because i already got a couple of them but if i went the 351w route with the truck i can just use it.

[49fordv8f4]

The T98 syncro-silent 4-speed was available as an option '48-'52 and as standard equipment on the F6 trucks with the 254 "M" series six. They can be quite hard to find. I have one in my '49 F4 with a 5531 Brown-Lipe 3-speed auxiliary for the overdrive. A 60s thru mid 70s Dana 60 is a bolt in swap. A lot of fellows go that route with the F2-F3 trucks. Rear brake parts for the Dana 60 are easier to come by, especially if you have an early '51 with the 14" rear brakes. You are also more limited with wheel selection with the 14" brakes.

I went with a T98 from a 1950 F4 and a Dana 60 with 3.73's from a 1972 F250. I also got the stock 16" wheels from a 1948 F2 and put 235/85R-16 tires on. Perfect for the way I use my truck but, overdrive would be nice for freeway cruising.

I got a lead.on a T98 thats local. Probably go that route with a dana 60 for now.
