Good afternoon,
I have a 68 F-600 with 330FT engine and 4 speed transmission with part # C5TA 7004 AJ F16.The bearings in trans. are beginning to be a little noisy.I was told by the ford truck parts dealer here that some of these trans. were almost impossible to get parts for[I had not gave him this #].I'm trying to find out what options I have as far as changing trans only,or maybe an engine/trans swap.Any and all help is appreciated.


Thanks

 

Don't believe anything you are told, especially by dealership parts clucks. For example, all the bearings/cups can be bought from NAPA, many other autoparts stores.

Bearings and bearing cups have a BIN stamped on them. BIN = Bearing Industry Number, these numbers are what every autoparts store and bearing shop go by. Here's an example =

CODW-4628-A .. Input Shaft Bearing Cup ~ BIN: HM88610 // C0DW-4630-A .. Input Shaft Bearing ~ BIN: HM88649 (NC source has 63) / Same exact parts used as pinion brgs/cups in myriad Falcon/Mustang/Maverick rear axles.

I can find every part for this trans NOS, and I wouldn't be a bit surprised if many are located in NC / Just because the parts are obsolete (or may not be-it depends...), doesn't mean no one has them.

Typical problems that affect the NP435.

B8T-7220-D .. NP435 Shift Lever Retainer Cap / Obsolete / Over 400 available NOS / One source in NC has 46.

This cap has two notches, is retained by two pins that protrude from the shift tower. To remove it, it must be pressed down, and held down while turning it (1/4 turn) to remove it.

Peeps are unaware, use pliers to remove it, which tears out one or both of the notches. Now, they aren't going anywhere. Not pleasant!
-----------------------------------------------------------------------------------------------------------------------------------
The shift forks have two nylon inserts on each fork. These crack apart, the pieces fall into the gears, can bind them up.

C2TZ-7C430-B (replaced C2TZ-7C430-A) .. 3-4 Shift Fork Nylon Insert / Obsolete

D2TZ-7C430-B (replaced D2TZ-7C430-A) .. 1-2 Shift Fork Nylon Insert / Obsolete

100's of each available NOS / NC source has 54 of the former & 41 of the latter / The seals are still available from Ford as are some other parts.

Today, most parts peeps know little about older vehicles, so usually say "obsolete" the second you mention the year...whether the parts are or not.

This BS is designed to just to "shine you on," because they don't want to bother.

 

Once again you have saved the day.Around here it seems as soon as you say 68 model ,a sign goes up and they say tou can't get parts for that.I would also like to ask if these sources for nos parts are fairly easily found on internet or is there another route you maybe could direct me.Once again,thanks.

 

Is the tranny noisy in all gears, or just one or two? And is it noisy when you are off the clutch in neutral?

Also, what weight oil do you have in it?

 

You need the Ford part numbers to search online parts locator sites like PartsVoice.com ~ Anyone can join, registration/searching is free. Much more than just Ford parts are listed.

All the numbers I typed above were found on PartsVoice. The NC source I mentioned is Carpenter NOS Obsolete Parts (known more for his repro parts than obsolete parts).

Carpenter is located in Concord. I've been there, twice...he's just up the road from Charlotte Motor Speedway.

But there will be other NC sources (that may be cheaper), plus other sources in surrounding states.

I also use the in-house FoMoCo Dealer Parts Locator System, but...cannot pass this info along.

I will list all the part numbers for the bearings, gasket set, seals, whatever you wish, post them here and type ALL the sources that have the parts.

The 1964/72 Ford Truck Parts Catalog is available on a CD from hipoparts.com for $21.95 / NP435: Text, Section 70 ~ Parts List # 70.6A (C5TA-7004-AJ).

 

Most noise comes from 3rd. gear and assuming prior owner didn't do something crazy,it seems to be 90 wt.I've seen some rebuild kits on ebay but I haven't got into trans yet to see what may be bad.I'm already feeling alot better about things since I see there are parts available.Even though the truck has several years on it,it is still a good,solid truck that I will probaly keep for a few more years.Thanks for help .

 

maybe these places can be of help to you !
