Pre-overhaul diagnostic scan
Confirms the fault and the scope of work required before anything is quoted.
Rebuilds & Reboots
Major overhauls require specialist tools, certified skill, and a structured workflow. All rebuild work is performed by Mr. Warambwa Samuel (Lead Rebuilds & Reboots, Certified Mechanic) using the Heavy Duty Hydraulic Stands and 800kg Heavy Load Moving Tray. All rebuilds begin with a full diagnostic assessment and a client-approved written quotation.
Engine Overhaul
Engine overhauls are the most complex workshop operation Avoo Motors performs. Every overhaul begins with a diagnostic assessment to confirm overhaul necessity and scope — protecting clients from unnecessary expenditure.
Top overhaul (cylinder head)
Head removal, crack test and pressure test, skim if within tolerance, valve grinding and seat reconditioning, new stem seals, head gasket, and re-timing. Estimated labour: UGX 400,000–700,000.
Short block rebuild
Block decking, bore measurement and honing or re-boring, new piston rings or oversized pistons, new con-rod and main bearings, thrust washers, oil pump and seals. Labour: UGX 800,000–1,500,000.
Full engine overhaul
Complete teardown, inspection, and rebuild of all components — combining top and short block overhaul. New timing belt/chain kit, water pump, all gaskets and seals. Run-in procedure post-build.
Heavy truck engine overhaul (Scania, HOWO, Isuzu)
Specialist heavy diesel overhaul — liner replacement, crankshaft grinding or replacement, bearing alignment, injector sleeve replacement, turbo feed lines. Labour: UGX 1,500,000–3,000,000.
