Hello woju81, a perfect, clean job as you build the MAZ-537. You are one of the few model builders who have changed the crossbar over the rear axles. I have never seen a MAZ-537 in the original where these breakthroughs were present in the traverse. In the parts catalog MAZ-537, however, the drawing also has openings. I wish you much success and joy for the further construction.

Best regards LKWMAN

Hi Joachim, I must say I have never noticed, even looking at the photos a hundred times, just recently thought that is something wrong with that rear axel rockers. Nice work on your btr - 152 BTW. Happy modeling. Wojciech.

Likewise with all the super detailing I have done of the several MA3 I have built, for some reason I never considered correcting those openings in the walking beam rear suspension. Kudos!

Hi Michael

I described this problem in detail in my construction report and showed photos. So far, hardly a model builder has noticed that this is wrong in the kit. Show the pictures of the MAZ-537 again for clarification.

I just always considered that this was a production change in the vehicle somewhere along in the life of the manufacturing run. I therefore dismissed the difference in this walking beam design on the model. I did not feel it was necessary to change it on my models though I compliment you on doing so.

Also the original Russian service manual shows the walking beam as an open girder design just as that employed in the model.

(Sorry - I have a copy of the actual drawing but again Photobucket is not letting me upload for some reason and tech services is not responding.)

It is my suspicion that the original open web design was a one piece machined casting that in use, had a high failure rate and was therefore later replaced with a welded up box beam structure for greater strength at sometime during the production run.

(If you PM me your e-mail I will send the image to you.)

Hi Guys, welcome after short break .I haven't been idle ,though. There was some painting going on with partial assembly. There is some photos.
