Re-Re Bruiser, clunking noise from the trans.

[GTodd]

How is everyone doing today? My Bruiser is giving me a hard time. I’ve re-built the trans three times and I can’t eliminate a clunk/binding that is in the trans that can be heard and felt when I rotate the spur by hand or when I use the 540.

My only idea was to use a different amount of .5 shims between the two gears, I tried adding one more for a total of three and I was still experiencing the same problem. When I go home I’m going to try four and then work down to zero, it’s the only idea that I have. All the teeth look good, ideas?????

is the shift rod in the correct spot? Try locking in place with the g2-g4 parts shown on step 36

Thanks, Ill check that out tonight, I locked the trans in 2WD High and it still makes the noise. When I first tested it the trans sounded smooth as glass, than I shifted it into different gears and the sound began, now I can get the clunk to go away. Ill try tonight. Maybe I didnt measure that one rod that is staionary correctly. The shif rod is one piece.

I had a similar problem with a High Lift transmission and it turned out to be the meshing between the motor pinion and spur gear, even though the meshng was fine !!

After numerouis rebuilds of the trans the solution was simply to loosen the meshing a tiny amount.

The 2wd gear had a tooth missing, replaced, smoother than butter now! Thank you for the recommendations, now for paint, going to be a "mounty".

I made mine a mounty too, never liked the back cap section

[GTodd]

I agree, however I purchased another body kit so I can rotate on the shelf (it will be ran! ). Tamiya shouldve released it as a Mounty anyway. The cab, battery box, bed, and one piece wheels are Mounty spec anyway. Regardless, I'm just happy that I can finally own one. I might even purchase an original 750 and transmission for added accuracy.

I think the majority of people remember the ''bruiser'' more so than the mounty. I remember back when I built a mounty new in the 90's everyone kept calling it a bruiser.

[TA-Mark]

I think that could be right billg4. Before I got onto the internet in the late 90's I'd never heard of the Mounty, but I'd seen the Bruiser on the shelf when it was first released (and it sat there until the Toyworld owners retired, and now it's hanging on his wall at home, still NIB).
