HI Andy,
1.5/ 2mm sounds a lot ??, I dont know if different thickness thrust washers are available
The last needle roller box I assembled I had to use two gaskets between the case and inner cover (I was in a hurry
) and it would have taken a trip to the city to get at a shim grinder
The STD box with bushes which have shoulders that make the difference between the two measurements
Measurement without the thrust washers should be about equal on both????
""I have picked up a L/S and a good set of L/S std gears and having now stripped the G/B have found that the 1st and 3rd gears of the std gears and the RT2T L/S are totally interchangeable. The 2nd gear of the L/S RT2T box fits either L/S. However, the std L/S 2nd gear with not fit onto the RT2T L/S. The engaging dogs on the RT2T gear are slightly undercut.""
So I would like to just replace the L/S and M/S 1st and 3rd gears (3rd gear ratios are the same anyway) of the RT2T box with std gears? I assume that you should change them as pairs so that the dogs match?""
I'm not quite following you here??????
Gears should be changed in pairs, and the total tooth count of any pair must be the same = 43
I went and checked the boxes that are still apart and both sets of sliding gears (2nd & 3rd) will fit either shaft ???
Go back to the previous page to see the photos of the difference between the RRTT2 and STD gears on the mainshaft ( E & F on chart)
Mainshaft and layshaft STD, E & F are needed to accomodate the STD first gear (G) due to the different engagement dogs
Are we getting mixed up with which each of us is calling second and third???
Too late to think any more tonite
John
