Preparations to remove the MK 5 engine continue.
Richard T and my self have been addressing concerns over noise and vibration on the ACRT. All fluids were checked, steering box and swivel housings found very low. Also transfer box oil level very low. Differentials topped up and prop shafts greased. Steering is now a little lighter and transmission noises have reduced marginally. It was noted that the engine mounts need replacing in the not to distant future.
Garath and son are continuing to prepare the Austin K4 body work for painting. Colin and Jim have the New Bedford seats installed.
Work continues with the now correctly assembled servo assembly going back together.
The cab continues to progress in the capable hands of Colin and Jim, the seat box is now taking shape.
The nose cone and grill prepared for painting.
Advantage was taken of the good weather to continue preparing the truck for repainting.
Kev has been matching up the refurbished grill surround to a replacement front panel, a bit tricky as both parts were already drilled. But being from different vehicles predictably they didn’t match up. Despite the discrepancy the finished result looks good.
Richard’s done a sterling job on the bumper of the Nuclear convoy vehicle. Welding an insertion repair to the right side and generally straightened out the dings and dents prior to it’s going for painting.
Progress continues, with the doors. Welding is completed and Richard assisted by Lee is well on with filling and preparation for painting.
Collins doing a great job with recreation of the seat box assembly, the Bedford seats have arrived and a set of series Land Rover rails sourced to hopefully allow the driver some adjustment. It will be interesting to see how they look.
The brake servomechanism has been stripped down for inspection, it’s not as bad as anticipated and renovation is underway. The internal linkage was found to have been incorrectly assembled at some point in time. Correction was interesting needing more fingers than Dave and I possess.
