Dismantling And Inspecting
Bolinder 1051 Engine No 1001
Discovered In A
Barn
ROUND 1
1. The Motor As Found Partially Dismantled By Persons
Unknown For Inspection
Top
2. Close up of the
engine identification plate, the number is noticeably shorter than
my other but
I have no way of dating at present (If any one has information on
this it would be very helpful).
Top
3. The flywheel had already been
removed along with the hand start
mechanism leaving the main bearing housing partially removed.
Top
4. By removing the 8 14mm or 9/16
bolts and reinserting two of them in the spare threaded
holes the housing can be gently eased out of the crankcase and
removed for inspection.
Top
5. The big end white metal bearing
has virtually no white metal left and shows signs of scoring.
Top
6. The big end is probably worn to an
oval shape to judge by the bearing wear.
Top
7. A view into the crankcase
including 5 of the 6 22mm 7/8ths flywheel securing bolts (anyone got
a spare about?)
Top
8. The rocker box top has a captive
22mm or 7/8ths bolt and will
lift off as it undoes 5 13mm or ½” bolts and rocker box lifts of.
Top
9. Remove the 5 22mm or 7/8 head nuts
a bit at a time evenly in a diagonal pattern.
You may need to use a rubber mallet or block of hardwood and hammer
to free the head.
(You could remove the injector first as the head will still be solid
to work on at this point).
Top
10. View of the
inside of the cylinder head note the apparently undersize valve and
waterways
partially blocked by rust debris some of which had fallen out. This
possibly led to overheating.
Top
11. An aerial view of the pushrod
tunnels and combustion chamber contained in the piston.
The bore appears to be in good condition and was full of diesel to
preserve it.
The piston appears to be stuck possibly sized.
Top
12. The motor and gearbox separated
after removing 16 14mm or 9/16 bolts.
Top
13. View of the input side of the
gearbox showing the planetary gears which enable reverse.
Top
14. View of the water pump drive
pulley and crankshaft output shaft.
Top
15. A 3 legged puller trying in vain
to remove the pulley, perhaps there is another way in?
Top
16. Removing diesel filter and
associated pipe work to make space.
Top
17. Crossland 483 filter.
Top
18. All injector and governor removed
as a unit showing cams and followers in good condition.
Top
19. Close up of the same showing the
oil pressure release valve behind the large cast cam wheel.
