About valves & valve train components

The valve train controls gas exchange and directly governs compression, starting and power. Valve clearances drift with running hours, so periodic adjustment is a maintenance task rather than a repair — and neglecting it burns valves.

What we supply in this category

Inlet and exhaust valves

Seal the combustion chamber. Burnt or receded valves cause hard starting and misfire.

Valve guides and seats

Locate and seal the valve; worn guides admit oil and cause smoke.

Valve springs, collets and retainers

Close the valve and hold it. Weak springs cause valve float at speed.

Rocker arms, shafts and pushrods

Transmit cam motion to the valve. A bent pushrod usually follows over-fuelling or a hydraulic lock.

Camshafts, followers and tappets

Set valve timing and lift.

Cylinder heads (complete and reconditioned)

Supplied assembled or bare where a head is beyond skimming.

Symptoms that usually point to this category

  • Hard starting
  • Misfire or rough running
  • Tapping noise from the head
  • Low compression on one cylinder

Symptoms overlap between systems, so tell us what the set is doing rather than which part you think has failed — we will help identify it before you buy anything.

Prices are indicative and shown to give you a working budget figure. Landed cost moves with exchange rates and duty, so the current price is confirmed when we quote. Availability is also confirmed per enquiry — we do not ask for payment on a part we have not verified. Bulk rates apply on qualifying order quantities.

Parts Ordering & Dispatch

Order spare parts from anywhere in Kenya — you do not need to travel to Nairobi

Send us your generator details and we will confirm the correct part, quote it, and arrange dispatch to your town. We also supply parts for projects across East Africa on a cross-border basis.

Dispatch options

Bus & matatu parcel services

The established way to move parts up-country quickly. Parcels are booked to the stage or depot nearest you.

G4S and Wells Fargo courier

Tracked courier options for higher-value items such as controllers, AVRs and electronic modules.

Regional & local courier networks

Regional operators and local parcel networks where they reach your town more directly.

Your own transporter

If you already use a transporter or have staff travelling to Nairobi, we can release the parts to them.

The channel used depends on the part, its value and where it is going, so we agree it with you per order and confirm the cost before anything is sent.

Confirmed orders are dispatched the same day. How quickly they reach you then depends on the transport chosen — commonly a day or two up-country. We will tell you which channel we are using and when the parcel has been sent, so you can track it from your end.

What to send us so we quote the right part

Generator parts vary between builds of the same model, so we verify compatibility from your serial number before quoting rather than assuming from the model name.

  • ✔Generator make and model (for example Cummins C55D5, Perkins 1104A)
  • ✔Engine and alternator serial numbers from the data plate
  • ✔The part number if you have it, or the old part
  • ✔Photographs of the part, the data plate and the controller display
  • ✔Any fault or error code currently showing
  • ✔The town or county the parts should be sent to

Availability: stock changes, and some items are brought in to order. We confirm availability and price against your enquiry before you commit to anything — we do not ask for payment on a part we have not confirmed.
