Popular Post 85snowdog Posted July 18, 2021 Popular Post Share Posted July 18, 2021 I'm very fortunate to finally have a DM. It was the very first Mack model I ever drove, and I've always liked them. This one is a very solid truck under all the bent parts , LOL It was used as a site truck and never got much attention. Its a 1989 DM 690 , T2070 trans with 300 maxidyne engine. I really like it !!!! I have a question though. Everything I've read says a Mack air shift trans will have an air filter. I can't seem to find one. Do they all have one ? Or have I not looked far enough yet ? Any info would be appreciated . Thanks 9 2 Quote Keith Link to comment https://www.bigmacktrucks.com/topic/67411-my-dream-machine-dm/ Share on other sites More sharing options...
MACKS Posted July 18, 2021 Share Posted July 18, 2021 Tough looking truck,the filter should be on the drivers side of tranny on the back of tranny,that’s where mine is anyway.. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/67411-my-dream-machine-dm/#findComment-477065 Share on other sites More sharing options...
85snowdog Posted July 18, 2021 Author Share Posted July 18, 2021 Thanks for the reply. I was under the impression its a spin on filter ? I think I must have it wrong . The only thing I can find in the air line to the shifter is this . Has air in and air out . If I clean it ,and tear it apart , It may have a cartridge in it ? Its not very big . On top of the trans on drivers side . Quote Keith Link to comment https://www.bigmacktrucks.com/topic/67411-my-dream-machine-dm/#findComment-477070 Share on other sites More sharing options...

T2070 etc didn't have any filter installed, just a small pressure governor (limiter?) fitted on the (rear?) top cover. Cool looking truck you catched.

Vladislav Posted July 19, 2021 Share Posted July 19, 2021 What is the size of the front tyres? Are they 385 or 425? I hope I will share the reason I ask the other day 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/67411-my-dream-machine-dm/#findComment-477104 Share on other sites More sharing options...

I hope I will share the reason I ask the other day Thanks for your thoughts on the filter Vlad. I don't see any sign of a spin on filter, so I think I will leave things alone . The transmission works and shifts amazing. I believe in preventative maintenance though , and didn't want to have trouble in the future . Thats why I was asking. I'm looking forward to seeing what you want the large tires for . It actually has 445/65R 22.5 tires on the front. 1 Quote Keith Link to comment https://www.bigmacktrucks.com/topic/67411-my-dream-machine-dm/#findComment-477115 Share on other sites More sharing options...

I agree, some faded paint is easy to buff out. I actually put the back tires on . It had tube type that were cracked really bad. Its got some bent things underneath from off roading. even the speedo drive at back of trans was bent, somehow ? Sure it was stuck bad. The frame is good though. Because it was a site truck most of its life, its never seen salt .

Normally I would never buy a "site truck" , but the lack of rust was appealing to me. It did look like it was well used. But not as bad as others I've seen .

Vladislav Posted July 21, 2021 Share Posted July 21, 2021 Those front 445 wheels seem huge. How do they correspond with the rears? I mostly mean the look. You put 11R22.5 in place of 11.00R20 tubes there right?

Thats what most people run around here. It wasn't till I looked for you that I saw they were bigger. My RD has 385's . I will take a pic for you to show the size difference. The 385's look small beside them , lol . Quote Keith Link to comment https://www.bigmacktrucks.com/topic/67411-my-dream-machine-dm/#findComment-477225 Share on other sites More sharing options...
