I have been very busy in the last three months. The balance between family, work, and hobby have been shifting a lot. Family has sadly been on the short end of the stick. I am working to correct the imbalance. I have gotten a lot accomplished on the hobby side. I have learned how to rebuild vent...

Hello All! we had a nice Veteran’s Day parade in Inverness Fl today. TheNational guard brought out an upsrmor Hummer, and I managed to get my M1031 drivable just in time. I love having the storage capacity for all of the gear we need for the Cadets to march in the parade.

Good to know. There is one near me that has the 887 body on it. He wanted 6k 18 months ago.

I am curious. What was the difference between the m887 work box and the m1031 work box? Did the m887 have the gasoline generator? I have seen some m1031s with PTO driven gens and some with gasoline gens.

I have an M1031 with single rear wheels. This is what I found on wikipedia: The M1031 was the chassis cab. These latter trucks were all rated for heavier 3,600 lb (1,600 kg) or 3,900 lb (1,800 kg) loads, compared to the M1008s 2,900 lb (1,300 kg) load capacity. The M1028A2 (converted M1031 or...

If you look at the bottom adjusting bolt on the power steering pump, the bolt takes a 15 mm socket. BUT, on the other side of the bracket is the “nut” that the adjusting bolt threads into. You can put a 15/16 socket on that. Then use a ratchet strap from the ratchet and socket to the outer tie...

I still use the one in mine. I list it as an antitheft device with insurance.

Good times this evening. The rear glass was installed yesterday. After school today I managed, with my good buddy Archimedes, to mount the work box back on the frame today. You get creative when you have to work alone.

My one man band is making strides in the right direction. I hope to be roadworthy for our veteran’s day parade.

Hello All. I have manageto get few more things done lately. The back of the cab is now painted. I hope to get the back glass in this week. Once that is done, I will be ready to put the work box back on. Apparently either I am able to or I am not smart enough to upload video. I have been...

Evening, All, Had a good afternoon today. Managed to get the diff back and set today. Had to replace the diff cover though. The oil/water mix that was in the axle created a lot of pitted metal. The axles go back in tomorrow. Next up: finish sanding and painting the cab so the back window...

As promised. Pic update. The last one reminds a little of the top down view of the M270s I used to maintain. Lol

I have been gathering parts needed to replace all the tie tod ends and front shocks in the near future. Spent time today cleaning everything to put the rear diff back together this coming week. Biggest move forward lately has been putting paint on the cargo box finally. I will update photos...

Hello all! Does any one have the manufacturer and part number of the amber strobe lights used on the roof of the m1031? thank for all replies! dean

I did a search and found this. It might be useful for you. https://www.musclecarsandclassics.ca/wheels/spare-tire/jacking-instructions/chevy-gmc-truck-jacking-instruction-decal-1985-1986

Now if only I could find the seals for the front diff in the parts manual…

After further perusal in the -34P I did find that you are correct. Thank you.

Good evening All, I have been doing dangerous things again … reading the TMs. Please someone tell me the difference between the front axle on an M1008 and the front axle on an M1031. I see that they have different NSNs and a difference in the LO for service. The front on the M1031 gets 4 ounces...
