Thanks Bob for the heads up. I found a used lamp MANY years ago. I gave up looking for a backup (new or used). Looking at the pic from Walmart, it is not even close to either the early or later lamp. The one posted by @BottleHauler84may be correct but too fuzzy to see any detail. Perhaps you can get a better image. My concern would be the wiring and connections. I am not a fan of "modifications" but I guess something is better than nothing. Thanks to both for your research and updates.

I am "guessing" the MH642/3 were Detroit engines? Anyone know for sure?

MH653 - Caterpillar 6x2 - single drive axle 6x3 - tandem drive axles A MH652 would be a Caterpillar powered single axle. Here is the link to a YT video explaining the differences in the CAT 3400 family engines.

I would say it is an optical illusion. The diamond plate fenders hide the tire (top and front). If you look at the distance from the rim to the ground it looks the same. The front "drive" axle is not a tag axle so the tires should be the same size.

Still looking. Added windshields.

MH parts: Windshield Moulding - 24RU538M subs to 25077244 - NOS pliable Windshield Washer Reservoir - 34QT55M2 subs to 25129768 - NOS or good used (mine leaks) New addition 04 JAN 2024 - windshields 9QT517M and 9QT518M. Send note to personal email with price and location. Pics if possible. Thanks!

There is one on the auction site that looks good. Send the seller a note and get the bolt spacing to make sure it is the correct one. https://www.ebay.com/itm/296089879417?hash=item44f0550379:g:nc0AAOSwDQVlbjML&amdata=enc%3AAQAIAAAA8PtmuW4Si3C8%2F4k3Ffpl18WRLiK%2FfzOo%2Bh1eGJpJk90sgo%2F%2FOlKHUL5h%2BE13XI9Q6aHG9qE04eYJJ2DsfvRYb95DWiwBgQXYOaMaKTtmLqCh6s1if8LP%2Bx5eZSxq6koTtStKofPKavx4M6LIammt55EZPOyToExDZYOlQ7PWD%2F%2FbnYc7ANBwPBgzQV4q9eqq%2BkHMp9VSFA5ImUwL0KpqLYWRRXpXpGy%2BITXDZA7CKUyKWIQ16OfjXMcU1KqnDWyODFb6ppHizApPGK35iaOGraiO31wI82n0p1O%2BYZz7XEWCaq0qzaYx0mTstR3yS%2F6t7A%3D%3D|tkp%3ABk9SR8Ctn_KGYw

I was asked to log in and reply to this message. You bought the "pup" version. You need to full size dog. The chrome bulldog pn is 27RU217B. The gold bulldog was not installed on the MH even if it was 100% Mack. The gold bulldog pn is 27RU217BP2. It attaches directly to the mount with 2 -1/4"x1-1/4" UNF countersunk oval head capscrews (pn 103AX109). I did a thread a LONG time ago about changing my bulldog from chrome to gold. I forgot to add 27RU217B subs to 2515 2847 and 27RU217BP2 subs to 2516 1913. Both list for over $100.

I was told there will be NO clam bake (buffet) on Friday night. Instead they are trying to get food trucks/vendors for Dutch Treat food service. I may only attend on Saturday.

Thanks Rob and AMEN!!!!! Going back to my hole.....

Bob, Sorry we did not connect and sorry you did not have a "swingin' time". If I knew you did not have a "pass" you could have borrowed the wifey's. My 3 cents on ATHS...I been to three (3) shows with the MH and NEVER ONCE did I need to show nor asked for the vehicle insurance or registration. Interesting! And don't get me started on the "show rules" and the number of "violations" I observed. And another thing, I never saw so many "service" dogs as in Reno (even in restaurants and supermarkets). On the positive side, lots of nice looking vehicles, most an "east coaster" would never see otherwise. Saw MHfred, Brocky, and 75T. Also Dave from Keystone Truck Museum. Make a note, Macungie is always Father's Day weekend (Thursday - Saturday). Many vehicles leave on Saturday afternoon so Friday and Saturday are the best days to attend. FYI, there is no spectator fee. Hope to see you at Watt's show in August. Take care!

Randy, The wifey and I plan to attend. I have a question...will there be NIT?

Hey everybody...keep the political stuff for another site. BMT is to discuss Mack and truck issues. A few jokes and personal items are okay but please keep the political (and any religious) discussion for another forum. You ask why many of the "old timers" are no longer here...think about it. As a few have mentioned to me in private "tired of the political BS on BMT". I know Barry does not want to censor any discussion, but this does not belong on BMT. Several other forums that I frequent will BAN such discussion and also many times the poster. We all have our opinions but this is not the place. End of rant! Have a good day and let me know when you want to discuss truck issues. I am gone....

Wingate did not have scrapple during breakfast. All this talk about scrapple has my taste buds excited. Going to buy some scrapple this week, fry a batch (crispy on the outside), and spread with apple butter. Yum yum!

Good looking decal. Let me know when they arrive and I will stop in and buy two (2) or more. And if you decide to offer a tee shirt....colors other than black.

Firemack on BMT That tee shirt is an "old" item. Mack, Watt's, and others used to sell them. I don't think they are available anymore. I like the new Watt's tee shirt with COEs on the front and conventionals on the back. But I don't like black...nothing personal Al.

Greg, Happy Birthday late. Hope it was a good one and many more!

Nice pics but no Mack trucks, no wimmin seat covers, and no windfall wimmin. You and OD need to talk at Macungie and get some picture takin pointers! See you on Thursday.

I will try some PB Blaster NO Spring Suspension - no ride valve

It was replicated when I returned the truck to its normal parking spot. Trolley lever never touched. What spray lube to you suggest?

Perhaps I am not clear in the explanation of the issue. The air pressure held great until Wednesday this week. The pressure (both needles) showed about 60psi. I started the truck, let the pressure build to 135, and the compressor cutout. I released the parking valve (yellow knob) and drove the truck about 50yards and stopped. I stopped, applied the parking valve, and shut the engine off. Two (2) hours later the green needle was 20psi and the red was 90psi. I did not blow the horn, disconnect the trailer air lines, drain the tanks, no nothing. After about two (2) hours I started the truck, let the air build to 135, and returned to the usual parking spot (applied brake and pulled yellow parking valve). 24 hours later both needles still showed 70psi. Again, why did the green needle drop to 20psi within two (2) hours and before/after it did not drop? Is the tread valve the issue? The yellow valve and the others were replaced about two (2) years ago. Perhaps I should just forget it and drive it fatter, dumber, and not happy!

My concern (puzzlement) is why did the green pressure drop over 70psi in two (2) hours? I am pleased with the slow drop over a day or two when previously it would drop to zero within hours. And also pleased the pressure remains steady during driving rather than constantly cycling. It is the engineer in me...sorry!

On my trip last Tuesday from PA to Lexington, the air pressure held a constant 120-125psi. On Saturday when I got in to drive from Lexington to OH the air pressure dropped to 60psi (both red and green needles about the same pressure) and again held steady 120-125 during the trip. On Monday I drove from OH to PA and again the pressure was about 60psi after sitting on Sunday and as before the pressure held steady during the trip to PA. Wednesday afternoon when I needed to move it to mow grass around and under the truck, the pressure had dropped to about 30psi. As before both the red and green needles read about the same pressure. Now for the puzzling part. After about two (2) hours I went to move the truck back to its usual parking spot. The red needle read about 90psi and the green needle read about 20psi. What the fluff is happening to the air? I didn't hear any audible air leakage. I always let the pressure build to 135psi before moving. Previous years the air would drain to zero after sitting a few hours or over night. Also during trips it would cycle every 15-30 minutes. I was getting confident this past week that the air pressure drop had mysteriously healed itself. I will see what happens when I drive to Macungie next week. I just checked and both needles are at 70 (after sitting 24 hours). What the hay!
