Installation

The LT230 has 2 ways to preload the intermediate gear bearings, the earlier design was to use the thin wall collapsible spacer which crushes as you tighten the intermediate pin nut which then preloads the bearings. The later design uses a thick wall spacer available in many different sizes which is just used as a shim would be to attain the correct preload. On these high torque engines, we favour the later thicker wall spacer method but because of the bigger bearing the stock sizes will not work. We would suggest machining the stock spacer down to the required height in a lathe, we have found 52.85mm to be correct but if you can get more, I would advise matching them + 0.05mm and - 0.05mm i.e., 52.80 and 52.90 and see how they feel.
