I'm hunting for some information that has to be out there but I haven't found it yet. Can anyone point me in the right direction?
I'm looking for a list of reamer sizes that are normally required for the different bushings on our Model Ts. I saw a Stevens (Speed Up) Tool Co. boxed set of 17 reamers that covered 29 different bushings. To find one of these boxed sets for the Ford T is very hard to do and most are incomplete or have badly worn reamers. As time goes by, we will need to replace these reamers and/or make new sets. The sets list the bushings they cover but not the sizes needed for each bushing. Yes, I know that a good micrometer will give you the size of the fitting and you add 0.001 to 0.004 inches to that for your reamer size depending on the part but there ought to be a table of the original Ford recommended sizes out there for a base starting point. Stevens Tool Co. must have had it to make the set, so where is it. I have attached a list of the bushings that Stevens said they covered with the 17 reamer set plus a couple corrections (I think) and one additions. Can anyone give me a list of what reamers and sizes cover which bushings. If you have the correct size for even one, I'll take it and add it to my list. I have three of the transmission sizes from the MTFCA transmission book and I know the 2713 is 0.5001 and 2714 is 0.560 but that is about it. Once compiled, I'll get it published so we don't have to go through this again.
I had a list but darn if I can find it. It may have fallen victim to the last drive crash. Most of those can be found in the back of the catalogs. Mac's, Snyder's, etc.
I've checked those spect. sheets and they are good but don't have the size a bushing should be reamed to. They have stroke, clearance and lots of good stuff, but not what the reamer size should be. Thanks for the pointer and keep looking where that drive crash occurred. Thanks Doug
Douglas, I have the special transmission set no. 4 and the reamers measure:
3304-reverse gear bushing =2.300
3309-slow speed gear bushing=1.655
The next reamer is a step reamer, with the following numbers
3320B C -driven gear sleave bushings=1.000
3311- brake drum=.935
3227B-driven plate assembly=.935
Nice set, Mike ! I also collect Stevens tools.
Here is where I get confused. Your reamer says, 3320B,C, 3311, & 3327B on one reamer but the sizes are 1" & 0.935. Is that reamer a double like the 2713,2714? Thanks for the info.
I'm looking at a Keystone 11 piece set with two worn and two missing and I don't know which are missing or worn. It is a transmission and differential set. Any thoughts on a Keystone set of reamers?
Douglas, yes it has 2 sizes on the same reamer. The first part of the reamer is .935 and then it steps up to 1.00.
Thanks so much. I have been going crazy trying to figure some of these out. I will sleep better tonight. I have these recorded now and hope someone will find a few more for me. Thanks guys.
That particular reamer is special to align ream both the brake drum & driven plate bushings at the same time. Due to the close proximity of the second brake drum bushing to the driven plate bushing, Ford eliminated the second brake drum bushing but recommended using a "special" stepped reamer for that purpose. There is a paragraph in the Ford Service Bulletins regarding the elimination of the extra bushing. One should note that after align reaming, one should "index" the brake drum to the driven plate for future disassembly/re-assembly procedures.
Douglas, I don't know if this will help you out or not but, I have a reamer with ford Part numbers on it
3042 Cam shaft front bearing
3044 Cam shaft rear bearing
3545 Steering Bracket bushing
because these three use the same reamer they should be the same size.
I have one of these also. Unfortunately, someone tried to clean it with a wire brush and it is as dull as a hoe. I measure it at 0.735. Can you take a measurement of yours? I would like to compare it to mine. Thanks
I'll measure it tomorrow. I have used it before but, it might be a little worn.
A side note;
Reams for transmission, rear end, drive shaft and steering;
The reamers are made to give the clearance of new bushing onto unworn parts and will give a different gap when mated to worn parts. The shaft the bushing rides on are usually worn so will have a different clearance(more) then new. The best way would be to hone the bushing to the proper clearance to fit the shaft it fits on.
King pins, tie rod ends and shackles are usually replaced as a unit so they would be ok to use original specks.
Thanks for sharing! I came accross this website to read more info on this great product:
Steve, I always figured Ford eliminated the rear brake drum bushing in 26-27 when the captured driving plate was introduced. Makes sense because in that situation, there is no possibility of the plate moving around. On the earlier version with the lip, there is typically a good deal of clearance between the lip and the drum surface where it bolts together. On these, I believe the bushing is needed to keep things aligned. I am not convinced the 6 bolts will hold everything true given the amount of torque on the driving plate. I know at least two transmission rebuilders that never install a rear brake drum bushing regardless of the year, probably because its so hard to get a good alignment. What's your take?
The Stevens list shows only one reamer, #2581, for the drive shaft bushing. This Keystone set also has just one, #2540, for that job.
I wonder why neither one provides a tool for facing the thrust surface.
