# Water Pump for 1968 MGB
Vehicle & Part Overview
The 1968 MGB should be equipped with a Moulton rubber-impeller water pump. However, mid-production variations exist on this model, and reproduction quality varies significantly between suppliers.
Sourcing Recommendations
For a late 1968 MGB in driver-standard condition, a quality reproduction pump is appropriate. When sourcing, prioritize suppliers known for consistent quality, as pattern parts of poor quality can cause overheating issues — a serious concern for B-series engines.
Fitment & Safety Notes
Important: Some reproduction water pumps are pattern parts that will not last and can cause overheating problems. Quality varies significantly between suppliers.
Before ordering, confirm your pump type:
- Check the inspection hole on the pump housing to determine if the impeller is rubber or metal
- Look for the original part number stamped on the pump casting
- Clean away any corrosion to read the number clearly
Mid-production variation means exact specification matters for proper fitment and longevity.
# Clutch Master Cylinder for 1972 Triumph TR6
Vehicle & Part Overview
The clutch master cylinder is a hydraulic, safety-critical component. On a TR6, failure results in complete loss of clutch function, potentially leaving the vehicle stuck in gear or unable to disengage drive.
Sourcing Recommendations
Do not use pattern parts for this component. Bore tolerances and seal quality on cheap reproductions are inconsistent.
- Rimmer Bros — carspanner.com/go/rimmer-bros — carries quality reproductions built to correct specification and specializes in early versus late TR6 hydraulic spec differences
- Moss Motors — carspanner.com/go/moss-motors — solid alternative for TR6 clutch parts and pricing comparison
Reconditioned Original Option
Consider asking Rimmer Bros about rebuild or exchange services for original cylinders. Reconditioning an original often preserves bore and casting integrity better than new reproduction.
Fitment & Safety Notes
Safety-Critical Component: Swelling or perishing seals in pattern cylinders are a known failure mode. Hydraulic integrity is essential.
The 1972 TR6 typically uses a 3/4 inch bore Girling-type cylinder as standard for that model year. Confirm your bore size before ordering.
