I am rebuilding the waffled/ribbed 1275 transmission due to a few ears that were broken during a crash in the original car. I am basically transferring all of the guts from the wrecked casing to the good casing. The cases are not the same. Questions are sure to come as I rebuild this one.

Question 1:
The thrust washer on the layshaft (forward) has indents to allow springs to (i don't know) possibly pump fluid as they ride along the washer. The new casing does not have the holes for the springs to fit into. Is this a problem? Do I need to use a flat thrust washer? When I install the ENTIRE laygear assembly into the new case, will it fit?! Will the swap allow for the proper clearance that is needed?

Thanks,
Barry
 
Is the casing you are putting the rib-case parts into a smooth case?
 
The later Spridgets had the springs to pre-load the laygear. Early model rib case units did not have this feature. I do not know if the later parts will go into an early case. I would think it would be OK. Just make sure the laygear end float is .001 to .003 instead of .003 to .005 as called for in the later unit with springs.
 
Thanks for the info. The laygear and thrust washers fit nicely. I have not had a chance to measure the end float yet. Just wondering which is better. I am sure that the newer case is probably a better desing, however, I wonder if what I am doing will be ok. Will this thrust washer be ok? If I have the .001-.003 end float all will be ok?
 
The early box had a 22g100 laygear. If the later unit is a 22g1100, I'd say you're on the right track.
 
Thank you sir. The more reassurrance the better!! I lost (I swear it wasn't there to begin with!) a spring and ball bearing that goes in the first gear-- hmmm gear. It will be here on Wed. There are supposed to be 3 and there were only two. Unless I lost it when it was taken apart. Amazing how those little guys can fly!!
 
Not only are they good at flying, I have found on re-assembly that they have a knack for finding their way into the wrong spot if you are not careful, requiring a tear-down and re-do (Had to do one three times to get it to shift right!!) Good Luck, I will be getting into mine real soon I hope!
 
Jolly Roger taught me a neat trick: put a hose clamp around those lil turkeys then tap your gear on (thus pushing the clamp off).
 
That is a neat trick that works very well. Actually what I was referring to as finding their way into the wrong spots were the detent "slugs/balls" meant for the gear selector shafts that go in through the bores under the side cover and from the bottom! Easy enough to do right if you are careful, but usually in the wee hours of the morning it's easy to screw up. If they do not wind up in the right spots you have to remove a bunch of stuff to get out the selector shafts to get them right.
