carrcrazy Posted September 27, 2019 Report Share Posted September 27, 2019 So, I'm in the process of rebuilding a F4w63 out of a 68 520. I currently have the trani completely disassembled and ready to go back together, but the problem is I cant find a rebuild kit for it anywhere online. If anyone knows where I might be able to find one, that information would be greatly appreciated! Quote Link to comment
MikeRL411 Posted September 27, 2019 Report Share Posted September 27, 2019 A bit late but the best approach is to buy the rebuild kit before tearing the transmission apart. [With age comes wisdom of so I hope. I'm 82.] 2 Quote Link to comment

Gaskets can be found individually... Bearings you might have get the numbers from the existing ones in the transmission and the match them through a bearing supplier.... Syncros might be the hard thing to find.. Quote Link to comment

Syncros might be the hard thing to find.. I measured the wear on the synchros, and they're surprisingly in great shape. The trani had way to much play and I found the culprit, but I'm now looking for the gaskets and bearings. I'm rebuilding the truck for a customer and he would like the engine and drive-train to be completely rebuilt after sitting since the mid eighties. Where would be a good place to look for individual gaskets, I've seen whats on Datsunparts.com but their prices just seem outrageous, especially for the bearings. I'm sure this has been asked before but I was drawing a blank when searching for it. Quote Link to comment
Crashtd420 Posted September 29, 2019 Report Share Posted September 29, 2019 I sourced all my bearings to rebuild my 71b transmission.... https://3bgsupply.com/bearings/ If you disassembled the transmission already you should be able to see the numbers on the bearings .... Gaskets , really depend, ebay and some part stores, even rock auto, and some times you can get lucky nissan will still have them.... Use this sight to find oem part numbers.. https://www.carpartsmanual.com/datsun/pickup-1965-1972/power-train/transmission-case/from-oct-65 You can use the numbers to crossreference ....

datzenmike Posted September 29, 2019 Report Share Posted September 29, 2019 This is a J13 engine transmission. There is a paper gasket at the front for the cover plate and one between the main case and the rear extension or tail. I would just make my own. All you need is thin gasket paper easily and cheaply bought, scissors, pen or pencil and a round hole punch from a dollar store. Presto... one L series oil pump gasket in less time that driving to town to order one and then wait and then drive back. I used a cereal box, but have gasket paper now. Did this years ago and still on an working as well as a water pump, fuel pump, thermostat housing and cover gasket. 3 Quote Link to comment
scooter Posted November 21, 2019 Report Share Posted November 21, 2019 I have done the technique that mike has done as well, with good results. I used a beer can box though 1 Quote Link to comment

pdp8 Posted December 21, 2019 Report Share Posted December 21, 2019 The problem with just buying seals and bearings individually is the cost does add up pretty quickly. I just got an overhaul kit for my 60-A for $142 delivered. It came with synchros, a half-dozen bearings, and a few seals. The bearings were made in Japan. It wasn't a soup-to-nuts kit, it would have been really nice if it included an output shaft seal and collar for instance, but was plenty good enough to deal with the normal input-shaft bearing wear, seal leakage, etc. on a otherwise decent gearbox.
