I replaced my shifter spindle now my shifter will not return up or down after shifting. I have researched the forum and looks like there are a few common parts that usually break and cause this. Nothing looks broke when I have the side cover off. Part #21 is in place and not broke, and I replaced the spring (20) and the plate (19) but same result. It works perfect when the cover is off, returns correctly and shifts smooth but when I put the cover on, It gets in a bind and does not return. I can make it go into gear and reverse but I'm scared it will damage something else if I keep doing this. The new spindle came from a 85 trx which had the same part # as my 1985 250es and looks to be exactly the same size. Am I missing something here? And to add to it, I over tightened one of the bolts for the side cover and cracked the inside casing where the bolt goes in. All other bolts get tight except this one which is right under the shifter so I am not sure if it will leak oil. The only thing I can think to fix this is JB weld but it may not hold when I put the bolt in. I don't think the cracked bolt hole is causing the shifter not to return though. I have went through 3 gaskets and keep taking both side covers off trying to fix this but no luck. The reverse lever on the right side (that goes on the other end of the spindle) is lined up correctly. So I am at a lost!
