yarnall Posted July 11, 2013 Share Posted July 11, 2013 Do you know the serial number? I have a 1950 that is serial number 10184. Is it yours? Looks like a good project. And welcome to the forum.

MADDOG93 Posted July 11, 2013 Share Posted July 11, 2013 I thought a LFSW had a off set cab very heavy duty. Is I wrong ? Quote Link to comment https://www.bigmacktrucks.com/topic/31896-lfsw-1951/#findComment-193626 Share on other sites More sharing options...

j hancock Posted July 11, 2013 Share Posted July 11, 2013 LF was standard cab position. Print date on brochure looks to be 1948.You're thinking of the LM which offered standard or offset cab and was heavy duty.Jim 2 Quote JimIt doesn't cost anything to pay attention.

Since yours is 3575 it is much older than mine. Somewhere in the forties. Does is have a 707 gas in it?

ap40rocktruck Posted July 11, 2013 Share Posted July 11, 2013 I doubt he is missing any letters after the "F" in the VIN. LF2D3575L = CabF = Hood length2D = tandem driveWould have been shipped as a straight truck, with frame rails extended past the rear rear drive axle.Your LFT1DLF = cab & hoodT = TRACTOR1D = single drive axle Quote Richard MarkOwner / Master Model Maker Industrial Model DesignAp40rocktruck Link to comment https://www.bigmacktrucks.com/topic/31896-lfsw-1951/#findComment-193634 Share on other sites More sharing options...

j hancock Posted July 11, 2013 Share Posted July 11, 2013 I am not aware of the "F" standing for hood length as it applies to an LF model.My understanding is the second letter is for the chassis weight. An LJ is rated for more GVW than an LF. A LM is rated for more GVW than either LF or LJ.This type of lettering system was used by Mack in the E series of trucks as well as others models.Jim Quote JimIt doesn't cost anything to pay attention.

RRJordan Posted July 13, 2013 Share Posted July 13, 2013 I don't know the particular truck in question and it has been a long time since I drove an LF in the mid-1950s, but I do recall that one had a Lanova and a 5+2 with a very low low range. It was registered in NY at 54,000 pounds and we normally weighed out at 73,000. It was supposed to have been a '50 or '52 that was rebuilt after an accident. It must have been the big Lanova because it would pull hills with the "new" B-63s in that yard with similar loads. It had a double frame and 11x22 rubber.

2stacksuperdog Posted July 13, 2013 Share Posted July 13, 2013 That sound more like a part number but im not sure.

Maddog13407 Posted July 15, 2013 Share Posted July 15, 2013 that's a Mack part number, anything with a Q or P in it is usually Mack part number. the serial number on the L models was on the ass end of the frame by or above the spring hangers. which is a horrible spot if the frame has been modified.

Vladislav Posted July 16, 2013 Share Posted July 16, 2013 I double it, 37QR531P3 is a Mack part number for shure.It's a bit strange to me but NR model wich was built too close to LFSW had the chassis number on a left frame rail in front, just above the front spring.Still haven't seen or heard about any L-models with the same location.

BakerBuilt Posted July 17, 2013 Author Share Posted July 17, 2013 Hi Guys .. Fuel tank tag says 9 51 .. I'm a busy guy will look better for sn tomorrow and take tarp off engine n measure bore, i studied the SINGLE drive axle looks original with a hefty damn park brake behind carrier brg .. funny that the fuel tank looks to only hold thirty gal with such a big sucking gas pot .. not too long ago i ran an old Rio w/w a 1693 best engine cat ever built it would not quit i could see the road thru the cracks in the wood floorboard especially over 70 loaded over 109k thats when it really performed n put out less than that was a cake walk .. looking at this i'm thinking it'd be more like hauling cows up to spring pasture at a 20% grade LOW HOLE all the way don't even think of grabbing a gear as the next corner becomes the HILL again ..klb Quote Link to comment https://www.bigmacktrucks.com/topic/31896-lfsw-1951/#findComment-194539 Share on other sites More sharing options...
BOB DINGSDALE Posted July 17, 2013 Share Posted July 17, 2013 that means tank was built in Sept 1951 so truck is most lickly a late 51 or early 52.I would say Sept or Oct 51 Quote Link to comment https://www.bigmacktrucks.com/topic/31896-lfsw-1951/#findComment-194588 Share on other sites More sharing options...
