Another Pioneer

Dare we ask how much?

A figure not far off what it costs to fill the tank on a Pioneer, I'm afraid. Not cheap but when you look at the work they put in to rebuilding these things it is pretty reasonable.

 

This is a snap of the speedo they did for the Sentinel.

Some more photos of the last week's work.

 

Inside the chassis rails at the front. Not easy to clean or paint but should be easy to keep clean in future. Nearside (incidentally the spots you see round the injection pump cut out is welding spatter not missed bits)

And the offside

Offside front axle in primer

Remember that manky nut over the page that wouldn't budge that I wouldn't risk knackering just to clean it? Temptation got the better of me and I risked it. Nice and clean now. The castellations were a little corroded but we'll live with that. Sorry about the blurry photo. Best I could manage.

 

3525030478_64ffd6d174_o.jpg

 

Perch bracket all squeaky clean in primer. New nuts to make it look nice.

 

3524222429_765d29e664_o.jpg

 

And inside the perch bar. Stripped back, wire brushed and primered. Bit of a pain doing the bits on the corners where the stiffeners are welded in but we got there in the end.

 

3524222517_63294b97e5_o.jpg

 

Some more OCD shots. Front of the engine around the crankshaft pulley. Not normally easy to clean unless it is all stripped down.

And the other side

 

3524223281_54e1b4deb6_o.jpg

 

At the bell housing backplate.

Yes Jim, enough. We get the idea. Have you done anything other than wirebrush and paint stuff?

 

Well the heads are back on. These didn't need anything other than a strip down, a light lap on the valves and reassemble them. The injector clamp plates needed straightened in the press and that was about it. The plan had been to go for refurbed injectors to get the K units but it turned out that it's already got K injectors so we'll just clean them ourselves.

 

The gasket set from Gardner Enthusiasts was very complete and pretty cheap seeing what was in it.

 

3525031660_8ded178c60_o.jpg

 

I don't know why that primer goes funny like that sometimes. It's not as if there was any contamination where the paint went. Odd.

 

3524222193_2f27040fcb_o.jpg

 

It will soon be time to paint it duck egg blue. Oh joy.

 

And finally, as promised here's some stuff in DBG. All parts are on their first coat. Some will get a second coat once it is back on and others will need to be painted fully before they go back on.

There is a lot still to do...

Shouldn't be too long before it can become a rolling chassis again.

Didn't appreciate the size of that winch bracket in the previous clean up photo's.

Having now seen it resting on the forks I realise it's huge.

I think you'll find the paint reaction on the engine block is ingrained oil. No matter how much you try and clean old castings there'll always be some oil in pores below the surface. A few coats of primer should effectively seal it and stop it showing through the top coat.

 

The rate your going with this project you'll be looking for something else to do over next Christmas.

P.S. Please leave some vehicles for the rest of us to restore.

It isn't really a reaction. The paint sets as it should and the surface just looks the same except it appears shinier than the rest. Once the proper undercoat is on it appears normal. Also if it were oil and other contaminants I would have expected it to be more common.

 

Paint used so far? Not a huge amount (I'll go and count the empty tins). We've been trying to keep the look as right as we can and most of the look seems to be that the paint is pretty much wafer thin. One of primer, one of undercoat and it looks like we'll have to have two of top to get the coverage with this paint.

 

As for polishing the flywheel it probably raises the important point of doing too good a job. When something is built in a hurry and thrown out of the factory gate with the expectation that it isn't going to last very long things like paint finish weren't a prime concern. This has made me a little reluctant to be too picky about the paint finish. Sure it needs to be clean and free of old paint when the paint goes on but some of this stuff is a nightmare to spray and overspray, missed bits and runs are almost impossible to avoid. It is possible to recify the mistakes but there is an argument that says when it was sprayed in the factory the same mistakes and errors would have been made - probably in the same places. I think the runs and errors should stay in the interests of historical accuracy.

...couldn't agree more with your comments on paint. It's hard not to want to get everything perfect, particularly when you've spent hours prepping it, then to get a run etc feels like I've bodged the job. But to step back, these things were painted to protect the metal, they weren't sold on the finish. Althought I can imagine that if there were too many runs, someone would be in trouble for wasting paint!

I have runs all over the militant, and I have to stop myself from rubbing the bits down and repainting, some bits will get left but I must admit that there are a couple that annoy me too much and will be re-done.

Some more pics from the last few days efforts. A reassembled radiator with one coat of DBG on it.

The front axle and chassis in undercoat

 

3532410781_648dd13245_o.jpg

 

There would have been a picture of the engine in retch blue but it got masked out. You get the idea anyway.

 

3533229564_122d1882a1_o.jpg

 

And from the other side. This weekend's job is to get the rest of the chassis finished.

 

3532410911_334abe869b_o.jpg

 

Winch ready to go back together. It would have gone back together but the bolt people sent the wrong length of CSK bolts for the drum ring gear.

 

3532411009_46dd9bffa2_o.jpg

 

Last few bits for the engine

 

3532411065_407246e770_o.jpg

 

DBG bits everywhere. That is pretty much everything for the chassis done now.

 

3533229808_6a51c059fe_o.jpg

 

Paying on gear.

 

3533229872_e1fdd47774_o.jpg

 

Nice big Meccano set. Flat pack Scammell.

 

3533229932_a4c0c36a7d_o.jpg

 

And that will do. Off to get some steel for the bulkhead today. Should start to look a bit more lorry like soon.

We use a local outfit so they are probably a bit far for you but they are a pretty helpful bunch.

The bolts were pretty much off the shelf so your local bolt supplier should be able to get them with no problems. I had to chisel all the nuts off ours - I think the mud sits on the top of the drum and eats everything. I would have thought there was enough grease and grime on yours to keep things in tip top nick.

That engine covering is translucent enough for us to get an idea of the colour.

You're going to have to strip of that shrink wrap and reveal it sooner of later. You wouldn't want it sweating and going rusty under the cover.

Fancy finishing off a Ward La France once you've done with the Pioneer? :whistle:

It's only shrink wrapped while the chassis gets sprayed. Some pictures of the weekend's efforts.

 

A water pump. Dismantled, checked, cleaned, all the valves lapped, the heater tapping blanked, reassembled with new gaskets and primed. Not a lot to show for about 4 hours work. Stuff like this starts to get a bit demoralising because you thing you are nearly there and you have forgotten about the countless bits you dismissed because it was "only the water pump".

 

3541167075_e21d673704_o.jpg

 

Ditto the oil filter

 

3541973118_767b537e76_o.jpg

 

In fact the red bits in this pile here (except the starter motor) represents my old man's entire efforts this weekend. It's slow going at times.

 

3541165897_d59c8c3f30_o.jpg

 

Whereas I had the tremendous fun of doing some more wire brushing.

Here's the gearbox. There will be more along shortly.

 

3541166123_2dfe8d56fb_o.jpg

 

Brake linkage mountings and some bits of chassis. The plan was to set all the brakes up before the winch went back on. It's dead easy with access from the top - especially the transmission brake.

 

3541166213_0a1f74ece6_o.jpg

 

From behind. All of this is hidden behind the rear guide roller assembly.

 

3541166301_e00959dfdf_o.jpg

 

Trailer brake cylinder mounting.

 

3541972532_1c90a18b30_o.jpg

 

Top of the gearbox from the nearside. Inside the chassis rails where you can't get to them don't look very good. Not sure what can be done about that.

 

3541972646_729c04a5e1_o.jpg

 

Rear of the gearbox and speedo drive. Tufnol gear in the speedo drive which was interesting.

 

3541166645_9620633806_o.jpg

 

The brake cylinder mounting. If you crawled under the vehicle with a torch and worked your head up under the winch drum, past the brake linkages and held your head at just the right angle you may be able to see this bit so it is important that it is clean.

 

3541166739_1845516c7e_o.jpg

 

Near side of the gearbox. Where necessary we replaced nuts and bolts where they'd been eaten away. That little alloy cover seems to be a trap of some kind. It appeared to be working because it was full of crap.

 

3541972932_877cc32d36_o.jpg

 

Off side of the gearbox below the chassis rail. Perhaps it was better not to keep a record of what has been done.

 

3541166929_9ac8c5dc36_o.jpg

 

Bored yet? Anything else to show? The front panel support brackets. Repaired and ready for top coat. Picked up a sheet of 1/8th plate so we can make the new front panel soon.

 

3541971880_0ea9d79306_o.jpg

 

I took the PTO off in the end because it was getting in the way. Cleaned up, new nuts and primed. Couldn't have got it to this state with it still in place.

 

3541165759_5165e1dafe_o.jpg

 

And finally a pair of clutch linings still in their waxed paper from Chelsea Friction. Certainly a lot more reasonably priced than the quotes we had got for relining the centre plate.

 

3541165591_1d2a89524e_o.jpg

 

Now the gearbox and all the chassis rails are done that just leaves the back axle and the inside of the rocking beams to do and that is pretty luch it until the body needs to get done. Then it can start all over again. Can't wait.

You could resort to blasting to get to the inside of those rails. :whistle:

 

Trouble is when you start getting things clean is stopping yourself from using it everywhere.

 

Don't you get fed up breathing through a mask all weekend?

If it's not dust it's paint fumes.

It's a sludge sump for the gearbox oil Jim, between the pump and oil rails. I would suggest removing the gearbox oil pump while it is all in bits and giving it a clean, but be aware the ball valves are different and must go back in the right place.

 

What was the outcome on the engine side covers?

Good call on the pump. We'll get that done before it gets painted. We've got a pucker workshop manual for the Pioneer so there is a decent chance of getting it back together the right way.

 

Parry got back to me about the covers but I think he is suffering from a shortage of hours in the day to get them done at the moment.

Was taking some pictures of the cab before it got pulled to pieces so while I had the camera in my hand...

 

A gearbox in primer

Needs another pass in primer. Not terribly easy spraying these fiddly bits.

 

Last few engine bits in undercoat
