On receipt, the clutch sleeve and overdrive unit is dismantled, thoroughly cleaned in a solvent bath and all components are checked for damage and assessed for suitability for reuse. The customer will be notified if components are found damaged and cannot be reused.
On reconstruction, all oil seals, gaskets, circlips and o-rings are replaced with new. The synchro hub is refreshed with new springs, balls and blocks. We also discard all of the old bearings and replace with a complete fresh set. The bearings we use are all high quality pieces from the likes of SKF, NSK or NTN.
Before we return the Overdrive, it will be fitted to our 109 and taken for a test drive for a through test. Once we are satisfied, the unit is returned to the customer with an insured courier. In the parcel we will include a new lock washer and nut for the clutch sleeve and a little tub of ROCOL anti-scuffing-paste.
Any parts beyond those stated that are found to need replacing, are done so at component cost only, no additional labour time is charged. To complete the rebuild takes around two days of workshop time and we aim to get units back in the post to customers within two weeks of receipt.
The charge for this service is £440, with the only additional cost being the postage to get your unit and clutch sleeve to us, plus any other component replacement costs
