BC Mack Posted June 5, 2015 Author Share Posted June 5, 2015 Does that battery box hold two n70 batteries? Might get one for my R model of so. Seems to be good quality.most usually they fit two Group 31 batteriesnot sure of your numbering system but this link may helphttp://www.batterystuff.com/kb/tools/bci-battery-group-sizes.htmlbox dimensions are... 18" long x 14" wide x 10" highnote... there is a "lighter duty" version in the PAI book, p/n FBB-4635, it does not have the side mounting holes or reinforcing angles.. I bought the "heavy duty" FBB-4986..Vlad,the rubber latch is includedtrial fit into my MH this weekend...FarmerI would say NOT the same, there are a few minor differences, the way the top lip for the cover is rolled and the mount for the rubber latch is bolted where my original is spot welded..BC Mack 1 Quote Link to comment https://www.bigmacktrucks.com/topic/40006-help-with-battery-box-part-numbers/page/2/#findComment-292341 Share on other sites More sharing options...
Timmyb Posted June 5, 2015 Share Posted June 5, 2015 With the help of my google machine, I was able to find that group 31 batteries are very similar in size to our n70 batteries. Interesting the little differences between the two countries. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/40006-help-with-battery-box-part-numbers/page/2/#findComment-292388 Share on other sites More sharing options...

"my summer project" of weekends, just plodding away, your MH will soon be glorious..!!!!if you need a real "time bandit" then restore an old seated coach.. trucks are SO easy in comparison..!!!BC Mack Quote Link to comment https://www.bigmacktrucks.com/topic/40006-help-with-battery-box-part-numbers/page/2/#findComment-292432 Share on other sites More sharing options...
Vladislav Posted June 6, 2015 Share Posted June 6, 2015 BC, my hats off to your seated coach deal. There was very interesting Russian intercity bus of the 50's - ZIS-127.Two stroke diesel, 60mph, aircraft seats, 851 example built.There are remains of 5 or 6 now in existance.One relatively solid is possibly avalible to get.Need lots of work sure.If I want to have a bus I would go that way.But I know it would be a death. 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/40006-help-with-battery-box-part-numbers/page/2/#findComment-292473 Share on other sites More sharing options...
mrsmackpaul Posted June 6, 2015 Share Posted June 6, 2015 Vlad I gather the 2 stroke was the Russian copy of the GM 2 stroke ?? rear engined I take it a bit of a Flxible Clipper type of hot rod very cool 1 Quote Link to comment https://www.bigmacktrucks.com/topic/40006-help-with-battery-box-part-numbers/page/2/#findComment-292474 Share on other sites More sharing options...
Vladislav Posted June 8, 2015 Share Posted June 8, 2015 (edited) Your right Paul, That Russian two stroker was a slightly reworked copy of 71 series. Had metric hardwear though. That's not good because I can't steal any rusty bolt from it to put on my Mack. They were 4 and 6 cylinder engines, were in production up middle 60's.

Popular Post BC Mack Posted June 9, 2015 Author Popular Post Share Posted June 9, 2015 Vladyesterday I did a fit check on my truck... not going to fully install for 1 or 2 weeks.... well, quality in China or Bangladesh or wherever this box is fabricated needs an audit...on the MH the clearance at the rear is tight on the rear cab mount... the metal folding and non jigging before spot welding the angle stiffeners is not exactly top notch... in the photo I yellow painted the material that needed removal...once mounted it looks fine... got to tweak a twist in my alum cover before I can install that... pending anything I haven't forseen it looks ok... will file a report when tank and batts are added.so.... should I have forked out a lot more money for the genuine Mack part that the dealer here wanted 400 bucks for?... this is a lower cost unit so I'm happy with my saving... I would have been pissed if I had paid the extra money to the dealer and he supplied THIS unit..!!BC Mack 3 Quote Link to comment https://www.bigmacktrucks.com/topic/40006-help-with-battery-box-part-numbers/page/2/#findComment-292700 Share on other sites More sharing options...

Vladislav Posted June 11, 2015 Share Posted June 11, 2015 Seems like a good thing in General.Minor filing doesn't seem to me as a trouble. Worth $300 on my mind.If it finally sits well and able to hold bataries I would say it's good work out.Thanks again for sharing the experience.

Popular Post BC Mack Posted June 17, 2015 Author Popular Post Share Posted June 17, 2015 Vladfinal installation today...other than a few minor points it went wellobviously the MH is not really what this is intended for but it works just fine, however, other than my previous pointers I noted two more items to keep in mind if you want to use this box on your MH..first, with the airtank underneath you have to modify the square hole for the battery hold down bolt to a "keyhole" because the bolt has to be inserted from above and slid into the lock position.... and... the top lip needs to be folded down slightly as the top lid fouls on the rear cab mount casting..I also discarded their bolt for the rubber clamp and used stainless..BC Mack 5 Quote Link to comment https://www.bigmacktrucks.com/topic/40006-help-with-battery-box-part-numbers/page/2/#findComment-293668 Share on other sites More sharing options...
Vladislav Posted June 19, 2015 Share Posted June 19, 2015 BC, thank you for pointing out the nuances.Nobody can do it as perfect if hasn't put his hands on.Glad to see the work checked off the list.

teleman Posted June 22, 2015 Share Posted June 22, 2015 I used the 4635 bottoms and 4636 tops for my B model and have held up good until I lost a top on the way back from Iowa...the guy down at the napa store got me another 4636 top for 65.00 and i thought all was good till they added 25.00 shipping...what can you say!!!!...Jim Quote Link to comment https://www.bigmacktrucks.com/topic/40006-help-with-battery-box-part-numbers/page/2/#findComment-294221 Share on other sites More sharing options...
