Following the instruction in the 1929 Chevrolet Repair Manual, took my time and tore down the transmission.

 

Here is the initial ROUGH Tear down to bare housing...

now to clean everything down and then prep for rebuild

 

going to soak and scrub the gears down then inspect them for defect, chips, cracks, etc...

 

see what it all looks like after some cleaning 🙂

dropped off the block, manifold, flywheel, cam ,pistons, rings, etc to the machine shop to start work. told me it would be about a week before he could start on the block work, also we are going to look at grinding and polishing the cam. going to order a new cam gear and thrust plate.

question for anyone that has rebuilt their Chevrolet transmission using the kit & parts i noted above.

well got around to re assembling my transmission. been trying to get everything in order for our annual swap meet so been busy !!

 

laid out everything on my bench then started to reassemble. used my Harbor Freight 20 Ton Press to press on the bushings. i used a lights coat of oil to ease to process. this was really easy to do, as long as you ensure everything is straight and in line.

 

20200229_163153.thumb.jpg.1e46edeb38b41a2b1439001ccec95b10.jpg

everything lines up and ready to press

20200229_163434.thumb.jpg.41fcdcdf90cc5b1af314b0235cf783ac.jpg

all in

 

did this for all the bushings on the gears/shaft. took my time and made sure it war correct.

 

once all the bushings were installed i did test fit each shaft to ensure that they went in smoothly and freely and spun with easily with no slop or play.

the black gook on the shaft was grease, used grease and oil coat to ease installation...

first to go in was the counter shaft cluster and shaft... then the reverse idler cluster and shaft. used the new shafts in the C&P Automotive rebuild kit.

this was a test fit, still need to line up holes and drive in shafts then pin them in.

next up was the main drive gear and shaft,

 

then the spline shaft assembly and gears. used my press again to press in the bearings into the housing and seat everything.

then i made sure that all the gears moved freely and that i could work the gears into all ratios with out an issue

 

i have not pinned the shafts in yet, just in case. 

 

next up will have to pin the shafts to secure them in place, and then start on the u-joint housing and assembly !!

Very nice work Jerry. Judging by the look of the tooth faces on your gears, your car either had an exceptional driver or wasn’t driven much. The old gears were never that pretty as far as the machining went but the faces were true. Yours still look virtually new.

     The trans in this 34’ pickup, even though its a early synchromesh, was really beat up. The shafts were really worn and deeply grooved compared to the bushings, the cones were worn, the shifter plate hole for the shift lever end, twice it’s correct width, the pin and the shift lever ball retainer all worn out, etc.!   I used three transmissions to make up one but now the rebuilt one shifts smoothly, has no more side to side lever swing, and just feels like a new trans. Steve had complained originally  that the trans didn’t feel right and boy, it wasn’t. He will be super happy with it when he gets it back.

need to tidy up loose ends and get the u-joint housing installed and complete the output end, then i can put the housing and all back on and ready for install. 

 

have a complete gasket set for the car. so all new gaskets on the transmission 🙂

 

u-joint will get cleaned up and gone over, then back on the transmission output shaft 😉
