RE: Another T-55 build/review
Thank you for the comments, hope this will be helpful to the first time builder.
The front (and rear) articulating arms are a nice mechanically working detail to add. Install the rotating pieces first then bolt together. Also shown is the suspsension stays. The metal housing is well attached by four bolts.
The tension spring is installed similar to the Tamiya Pershing springs, take care to identify the correct tagged spring for each roadwheel as the tension is different just like the Pershing for front-rear weighting balance.
The idler uses a continuously variable (bolt with a lock washer and nut) design that is very similar to the Tamiya Leopard 2A6 idler adjust except more robust and capable of fine adjustment rather than stepped. A nice improvement over the Tamiya system.
The idler needed a shim washer to eliminate slop and the idler arm had to be bored slightly to accept the wheel axle. Add ceramic grease and your good to go.
