Ok. The toploader...I bought the David Kee master rebuild kit for racing (the top end kit). When I disassembled the trans, I left all the gears intact and had determined the best way to do that portion of the rebuild was to assemble it immediately after the disassemble so as to have it fresh on memory plus be able to "stack" the parts up the same way they came off the shaft. The disassemble went smooth enough (doesn't it usually)? Removing the rear bearing was probably the hardest part at this point but it simply came down to knowing the shaft through the bearing while the ring on the bearing rest against the case.
Now the assembly. I started with the two bottom row of gears. They have needle bearing in them which I know can become a pain (and they will in this case as well). I assembled both of them, making sure the bearings were all in and used a brown colored bearing grease to assemble them (found out later what to use on these and it works). I got them both installed with the thrust washers (now plastic instead of bronze) that go on each end of them...no worries, for now.
Next I moved to the 1st and 2nd shifter rod, shifter arm and detent. It was easy enough so I jumped ahead to the other shifter arms and detents and found this trans was missing two detents. I had also figured out that you need a good pair of snap ring pliers. I ordered the detents and the pliers, again from David Kee. While waiting onthe parts, I decided to go ahead and tackle the center shaft and gears and get those parts replaced. Can't remember at the moment what I got wrong but I had to disassemble and reassemble to get everything correct. Once finished, I knew the installation of the rear bearing would be a job, having to press it on. I cut a piece of 1 1/2" galvanized pipe I had in the shop the length needed to install the bearing. I rested the front end of the shaft on a metal plate, put the pipe over the tail end of the shaft and pressed the bearing to the point (watching carefully) that the snap ring would just fit to hold everything in place. PERFECT!! And to top it off, the parts are in.
Time to install the shaft and gears into the housing. Now I remember why I had to take it all apart again. The shaft will NOT go into the housing with the rear bearing installed. It lacks about a quarter of an inch, but it won't go. The best way to get the rear bearing back off was to disassemble the whole shaft so you can press it off against the race. So you have to press the rear bearing on with the shaft and gears in the housing. Another painbut got it done, again watching carefully to get the bearing on in the correct spot for the snap ring to go on. This snap ring is particularly difficult because you have to pass over a section in the rear of the shaft (where the speedometer gear goes) that is the same size as where the snap ring installs at the bearing...another pain.
Got through that and it's time to get the shifter rods, detents and arms installed. Took a little to figure out where everything goes, but not too difficult to do. Pressed the front bearing off with the help of an old 2014 F150 front rotor. :grin2: Pressed on the new front bearing (two inch pipe and a 2" tee I had) and ready to get this over. RIGHT! You cannot on a close ration toploader install the front shaft and gear with the lower left (from the front) set of gears installed on it's shaft. Ain't happening! So I do some research and find on VMF where this had already been discussed. The consensus was, you have to drop the lower left gear cluster. But what about the needle bearings? Not to worry if you used grease to install them, they will stay. Well let me correct that statement. If you use the CORRECT grease they will stay. I dropped the cluster and installed the front shaft. turned the housing over so the cluster would get back in place and tried to install the shaft. Well, I wound up with exactly 42 needle bearing after finally digging them all out because they didn't stay in place. Time to go home at that point and really think about this. Disassembling again was disheartening at the least.
I decided to try and get the needle bearing back in place without doing a disassemble. Pull the ring that goes in place towards the front on the front bearings and towards the rear on the rear bearings and put them in place through the shaft hole. A long shot at best was my thinking but better that a disassemble. Talked to Patrick and Mark, Patrick saying use red grease (tackier than what I was using) and Mark suggesting petroleum jelly. I had petroleum jelly on hand and decided to use it. Surprisingly, this was easier to do than I had anticipated. The petroleum jelly worked wonderfully to hold the bearings and it was fairly easy to install the bearing through the rod opening. If you have large fingers, forget it!! I got the shaft back through the cluster and was VERY relieved I was able to accomplish that task without the threaded disassemble.
I'm not finished yet. I replaced the front seal and plate without issue. I removed the rear seal and bearing with no issues either. The rear bearing was a task. Hard to get in. I actually had to file the rear of the bearing with a rat tail file because it was a bit pressed. I don't think it will be an issue. I had to order the speedometer gear that goes on the rear shaft as I found this one was not what I would consider optimal. I'll post again when it's completed. Hopefully you can see some of what I've been describing in some pictures I took.
As an end note, buy the specialty tools to do this job. The snap ring pliers, the magnet and such. If you don't, you'll soon wish you had. If you have a press, you can do this job completely. It's not what I would consider hard, but there are things to be learned...
I then went fishing.
