Thank you,

Idle RPM is about 500-600
It does engage better when i accelerate. Should I increase the Idle RPM
Thank you

Re: Reverse gear grinding

I'd think it would be just the opposite. Rev gear on Mercs (the one's that I know) is a cog-tooth arrangement where the gears have vertical sides. That means that the clutch dog's teeth have to match exactly the R gear's teeth and then it can engage. If your rpm's were too high then it would be harder for the "pins and slots".....teeth , to line up.

Totally agree on the "snap" of the shift lever into gear.

Lastly, your shift linkage may be adjusted (maladjusted) a little in the direction of F which would reduce your leverage in cramming R home.

Thank You Mark.
That was very informative. I will try to adjust the linkage and post the result.
Thanks ,

PROBLEM SOLVED!


Adjusted the linkage as suggested. That was all it needed. Now the reverse gear engages without hesitation.

Thank you very much
