Parts for sale in The Netherlands

Over the past few years Arthur has acquired some engines and a box of parts. The engines have been dismantled and cleaned for inspection, and listed for sale. Arthur has taken the liberty of making the GTL parts manual into excel, and will combine the SD specific parts into that excel list. The excel list will be made available, and reserves the right to make typing mistakes 🙂
Should you be impatient the feel free to drop a message to Arthur to get your copy of the parts list.

Gearbox parts

The shafts from which these gears came from were so far gone/worn (loose sprocket) they couldn’t be refurbished without a mortgage. The gears themselves on the other hand are in good condition for further use. Note: the 1st and 3rd gears from this gearbox were also worn beyond refurbishment so not offered.

NOTE: there is one 350GTV engine which is complete except for the gear change cover. With the parts available there is an option to rebuild this engine up as original 350, or as a 500 in GTV disguise. in all cases, the cylinder head and camshafts will be modified for external oil feed to the left side camshaft cover.
