Gearbox repair and overhaul service.

I have made and created and updated several tools that Citroen used in the 1960's gearbox repair manual. A vast improvement to a, now complete, full kit of repair tools to totally renovate this item. We are now in the year 2019 and things needed to be brought up to date.

A complete overhaul is the only way to ensure that the gearbox will be entirely serviceable for many years to come. A simple repair or component replacement does not guarantee this.

All bearings,oil seals, needle races, thrust needle races, synchro rings, shims etc will be replaced with top quality components.The sliding pinion for 1st/reverse gear can unscrew itself and cause a total disaster. This item will be properly secured within itself.  Any damage etc found upon inspection will be reported to the owner. The bevel gear will be set to the factory dimension as well as the meshing of the crownwheel to it.
The gearbox must be delivered to my workshop and must be picked up at the same.
Turn around time can vary. Parts need to be ordered or made, but generally, 2 weeks should see it completed.

Please enquire and we can have a talk about repairing your gearbox. Pricing is available but a final quote cannot be estimated until and after stripping and inspecting.

You can, of course, hire any tools from the kit to complete your own repairs or even the whole kit. There are fourty odd tools in the set. The kit is not for sale.  
Sorry, but I cannot make a repair in the field, so do not offer a travelling service.
