Some photos of my 1998 GMC Sierra C3500 dually

As you go down the page you will see the work I have done.

My new toy GMC C3500

Just got a new GMC Sierria Dually

My latest American pickup truck

Wanted something bigger so got a GMC Dually 5.7L

As you can see it's in need of a paint job and this will soon hopefully be sorted to make the back match the front.

I collected this from near Lancaster and on route home it broke down just north of Birmingham! It had been leaking oil "lost about 2L in total" but this was not the main problem, it cut out and the engine just would not fire up again. I got it recovered back to Northampton and I am waiting to hear back from a mechanic with some news.

With breaking down on the M6 also caused problems as a small truck came out that was unable to get me off the motorway so had to wait for a low loader, well it arived and as you can see here he had problems fitting it on his truck.

My GMC Dually was a little too wide for the tow truck

My C3500 Dually truck was also too long and over weight for the small truck

As you can see it was too long, too wide and put his small transit can well over his weight so needed to wait for a 3rd truck.

Bigger tow truck for the GMC dually

and it fit on this one but the driver still took photos to send to his bos to see if he was OK to take me.

The Dually only just fit on this tow truck

As I do work on the truck I will update this page with details and photos.

Getting the truck back on the road

Latest news is the truck is now running after needing new crank sensor and cam sensor BUT it still has the oil leak that looks to be coming from the rear main seal. As this is a one piece seal the gear box now needs to be removed and the garage don't have the space to have my truck sitting there while I source the parts!

I am hoping to get the body work done and I will get the parts on order, Rear main and sump gasket to be on the safe side. I have found another garage to do this work for me but all these unexpected repairs are mounting up.

I have just had a chat with the guy I got the truck from and he has agreed to go half with the above repairs. I am happy with this, a fair man.

Today 23/July/16 I collected my truck from Northampton and took it to Braintree to have the oil leak sorted. While its there it will also have a full service including internal gearbox filter ETC. I am still getting quotes on the full paint job.

Spent a few hours working out how to fit a 1 din radio unit into a over sized 1.5 din hole where the very strange size "non working" radio CD was fitted. Some time in its life someone had cut off all plugs so was trying to work out the speaker wires. Well after a while I could not fine one working pair for and of the 6 speakers! So I thought I would remove the door cover and check the wiring colours only to fine no speakers fitted where they should be! So something else I need to buy. Just opderd a pair of Alpine 6.5" speakers for doors.

Also removed rear bumper and removed all but 2 of the bolts that hold the rear tub in place, I will remove last 2 bolts when I take it for the new paint job as I want it painted at back of cab and tub.

Rear tub lose and bumper removed ready for paint job GMC C2500 Dually

I have now removed door cards and roof lining so when painted the door shuts can be done and last job will be remove the screen "windsheield" as there is a leak from the top. Hopefully the guy will get it out without cracking it.

Just got some orange scrim foam backed textured faux leather to re cover the roof lining and parts of the door cards.

The screen guy came round today and pointed out the real bad scratches on passenger side so I think I will go for a new screen so he getting me price and I am doing same. Looking more into the water ingress at top of screen it looks like it could be coming from the marker lights. When searched on Goggle it seems many have this problem so I have just placed order for a new set from the states.

Re-Spray Decisions

On the subject of paint I have decided to go with Black and Orange

Top Panther black "Ford" and Bottom Electric Orange Pearlescent "Ford"

Had major problems with the local spray / body shop, after having it for over a month and kept fobbing me off with delay's I collected it on Friday 21/Oct/16 and the following day took it to another place. The new body shop said they are busy this coming week but will get started on it the following week.
