International BTD20 Crawler Restoration – Week 7

March 17, 2010

Week 7 of the restoration, not the most exciting part of the restoration, but every small gear and bearing counts if we want the finished machine to be perfect!

BTD20 Restoration

Not much interest, but proof that we have been doing something this week!!

BTD20 Gears and Bearings

A pallet-full of very healthy gears and bearings to be re-installed when bottom shaft returns from having its gears press-fitted.

As I write there are two engineers in the workshop working on the BTD20  right now! So hopefully week 8 will be much more exciting!

International BTD20 Crawler Restoration – Week 6

March 9, 2010

Week 6 of the restoration and the BTD20 is coming along! We had a nice surprise when we found that the flywheel is still in good condition.

BTD20 Clutch Pressure Plate

Removing clutch pressure plate to enable access to front of gear-box.

Dismantling BTD20 Gear-box

Eamon Pell starting to dismantle front of gear-box. Flywheel can be seen in good condition.

Tomorrow we will be sharing an insight into what else happens in the Walker Plant workshop!

International BTD20 Crawler Restoration – Week 5

March 1, 2010

It’s been a bustling hive of activity at Walker Plant Head Quarters so not much of the restoration done this week, but it’s amazing what can be achieved in an afternoon!

BTD20 Restoration

Eamon Pell working hard, in driving rain, removing the ‘Top Shaft’ from Donor tractor gear box

Pinion shaft removed at long last and, although a bit rusty, is found to be in good condition.

That’s all for week 5! I know we keep saying how busy we are in the Walker Plant workshop and it’s all a bit mysterious, but our workshop manager has agreed to share some of the other projects on “newer” machines that we currently have ongoing! He’s gone into the workshop armed with a digital camera and will hopefully come back with some very interesting stuff next week…

International BTD20 Crawler Restoration – Week 4

February 23, 2010

It’s been a busy week in the Walker Plant workshop, which we certainly don’t mind, but it does mean we have less time to dedicate to the restoration of the BTD20.

However we did manage to do some work, if only a little, this week.

Steering clutch release shaft

Left hand side steering clutch release shaft is fitted.

brake band

Right hand side brake band repaired and fitted.

That’s all we achieved this week, but we are planning some major work next week!

International BTD20 Crawler Restoration – Week 3

February 16, 2010

Week 3 of the restoration has been quite productive. As we get further along with the restoration we are finding out more and more what great shape the BTD20 is in for her age!

BTD20 Steering brake in poor condition

Right side steering brake, found to be in poor shape and bands will have to be relined

BTD20 Output Shaft

Resealed out-put shaft in left steering clutch fixed and returned to nice clean housing

BTD20 Fly-wheel

Fly-wheel cover removed ready for removal of main engine clutch to facilitate gearbox disassembly

Temporary exhaust manifold

Temporary exhaust manifold fitted to avoid new paint spoiling  stainless steel silencer/manifold

BTD20 Disassembled Parts

Disassembled parts waiting to be palletised, in readiness for paint shop

The restoration continues next week…

International BTD20 Crawler Restoration – Week 2

February 9, 2010

Updates of how our International BTD20 crawler restoration is going, week 2…

Ok, ok we know technically we should now be on week 3 of the restoration, however as the workshop was so busy the previous week we didn’t even get chance to look at the BTD20! So if you can forgive us, we will call this week, week 2!

Bevel Gear Pinion Shaft

Main reason for transmission repair work is this bevel gear pinion shaft with damaged teeth. Probably due to low oil levels.

Steering Clutch

Preparing steering clutch for removal.

Oil seal

After a struggle, the clutch is removed in order to replace the oil seal, which is directly attributable to bevel gear damage.

Main Gearbox

Main gearbox is suprisingly free of wear or damage, not bad for 40yrs of service!

oil seal disassembled

The offending oil seal – took 8 hours of disassembly to get to it!

Hopefully next weeks restoration work will go ahead as normal! So please check back next week to see how we are getting on.

BTD20 Crawler Restoration – Week 1

January 26, 2010

We are currently restoring a BTD20 Crawler. We have decided to post a week by week diary of the restoration for fellow restoration enthusiasts…

Week 1!

After carrying out an inspection of the machine we have list of repairs that need to be carried out.

BTD20 Rear Sprocket

Rear sprocket to be replaced if or when we can find another

Oil on BTD20 Floor

Oil on floor, means trouble from gearbox / steering clutch
housing. Fairly big job to replace, but seals readily available.

BDT20 Drawbar

Wear on drawbar guide means some extensive re-building.

BDT20 Floor removed

Floor cover removed ready for gearbox rebuild.

BDT20 Strip Down

Another image of strip-down in preperation for re-paint.

BDT20 Near side track adjuster

Near-side track adjuster removed for seal repairs and
broken studs in front idler yoke ready to be removed with the 
assistance of heat.

BDT20 Floor removed

 another image of floor cover removed ready for gearbox top
to be separated.

Come back next week to see what progress we’ve made…

Engine Smoking Diagnosis

January 18, 2010

Engine smoking is usually an indicator of underlying problems. Early diagnosis of machine problems can help prevent catastrophic failure.

If your plant machinery is smoking here are the possible causes: –

Excess black smoke at full load:(hot, unburned fuel) • Dirty primary / secondary air cleaner• Operating in too high a gear• Overfueling• Overloading• Faulty turbocharger

Blue smoke:(oil consumption) • Hours on engine• Worn rings/liners• Worn turbocharger seals• Worn valve products

White Smoke:(steam: water in combustion chamber)(or start-up: unburned fuel) • Leaking head gasket• Cracked head and/or liners• Faulty injector• Incorrect starting procedure• Incorrect fuel injection timing• Low quality fuel

Visit our workshop page for more advice and early warning indicators.
