Re: Another NV4500 to NP205
advance adapter bell is worth it. I have it with hydraulic clutch in my 85 blazer. if you redrill the case you could end up like a guy on ck5 and the loctited torqued bolts could back out and cause catastrophic failure. unikely but would ruin it and turn it in to a terrible situation just to save a couple bucks.
I have the 32 spline flat flange with a ford superduty front driveshaft. It is 1350 spicer ujoints and a 4.25 bolt circle with the 2" pilot. fits almost any new flange out there nowadays and is very easy to find. Do some research on em but a new one can be had here locally for 400 built to your measurement. There are two different types. the rounded cv yoke ears is the ideal one. sunsoaked, stock front yoke on the d60 is 1310 which is generally more than sufficient for most folks. but there aint no kill like overkill.

Re: Another NV4500 to NP205
dana44 / corp 10 bolt and dana 60 front yoke at the diff are same size all 3 . only major thing to watch for is durring axle swap to dana 60 . pinion is bigger and sits back more . so check for drive shaft length so no bottom out problems.

Re: Another NV4500 to NP205
Since it is too cold to be in the garage I'd like to post an internet find here for the NV4500 assembly manual. I can not figure out how to reduce the file size any further than 1.2Mb (down from 3.4Mb) and the limit to attach here is 275Kb. If anyone wants a copy, PM me with your email and I'll send it that way. Sorry it is for a later 2001 Dodge version but you get the idea anyway right? I think what I will do is disassemble mine and then order just the bearings/parts that I feel need to be changed instead of buying a total rebuild kit like some vendors put together. As an example one vendor has a bearing kit that goes for around $330 and that includes what they call a small parts kit. I'll see what condition my parts are in first and then go from there to try to keep the cost down. I basically did the same thing on my NP205 and bough each bearing I needed separately and that allowed me to get good old made in the USA bearings at a little extra cost for the good stuff. I know I'll need syncros for sure already. Here is a tease shot since pictures are everything....

Re: Another NV4500 to NP205
I'm at the point where I need to remove the main shaft bearing and the counter shaft bearing to complete my NV4500 disassembly. What have you used to remove your bearings, short of ordering the factory tool pictured.? It seems to me that a normal bearing splitter might not work due to the small clearance between the bearing and the gear face (see arrow). I made a 5th gear nut wrench that worked perfectly. I had to stand on the end of the "wrench" that is 30" long and I'm 165lbs so that is somewhere around 300ft lbs. I cut up an old 32 spline long input shaft from an NP205 as the main shaft counter hold portion. It took me about six hours total to make both out of scrap steel I had in the shop. Recycle!

Re: Another NV4500 to NP205
Alrighty then. I got a cheap clamshell style puller online to see if it would work and it did for two of the three bearings. The one bearing it will not work on is the tapered roller on the forward side of the counter shaft. I'll cut that one off just to save time.
Here is the new puller in action. I had to use an old piece of DOM tube as a spacer since the one provided in the kit was too long. One thing that was really frustrating is that the new tool has no place to counter hold, to stop it from spinning. I may weld a couple of flats on there for future use. So both the main and counter shafts are completely disassembled now and they both look in really good shape. I can tell this NV has been overhauled at least once before as there are a few clues like silicon sealant and a few scratches on the shafts where the bearings reside. I'll need all new bearings and syncros and a new input shaft as that is toast. The splines are really worn where the clutch disk was riding and the stub nose where it joins the flywheel pilot bearing is also trashed. I just need to sell a kidney or something to get the rebuild kit.....

Re: Another NV4500 to NP205
fyi that style puller needs the race set on the bearing to help it stay toghter when pulling off .
and if your doing gear setup adding & removing shims this fact is real important to not trash your new bearings .

Re: Another NV4500 to NP205
Yes, this kind of puller does trash your bearings, but they're OFF! and the new ones will be a lot easier to install, cool the shaft with dry ice and heat the bearing to about 350. No diff work just yet.

Re: Another NV4500 to NP205
cause like I said you didn't set the race on the bearing first and set the rings up correctly .
if done right you can pull off and reuse as many times as you want . also lube the heck out of the threads with copper anti-sieze . https://www.youtube.com/watch?v=CUqSZelTSfI https://www.youtube.com/watch?v=mkPPwfzD8Vg

Re: Another NV4500 to NP205
Oh, right, the outer race should be placed back on top of the bearing and then pulled. Don't really care at this point but thanks for the tip for future reference. These bearings need to be replaced anyway due to the wear patterns. I cut the counter shaft end bearing off earlier today so now I just need a bearing and small parts kit. Donations anybody? Ha.

Re: Another NV4500 to NP205
I am wanting to rebuild my NV4500 to save money too, I got the Kent Moore kit for the trans off ebay for a low price, but I can't find that tool you made for the rear bearing. I may have to think about making one like you did. I hadn't thought about making what I need.
