Bad Parts

    This page presents a list of available parts that are proving to be problematic.  Since Motorhead is a full service (nearly) shop and parts department we have the (almost) unique ability of testing how the parts we sell work and fit. Our parts department allows us to be thorough in our repairs.  Everything we sell or do is warranted for a year, so our shop helps test what we sell through our catalogs. While we try to sell original equipment parts, even OEM parts are proving to have defects.  Usually, in the case of reproduction parts, there is only one version of a repro and all British parts suppliers sell it. However, if there is more than one version of a reproduced part Motorhead will always provide the one that proves to be best.  The following is a list of Bad Parts. These are Bad Parts regardless of their source.

Problem
     
Air Pump

APP 100B

 Rebuilt air pump's Several rebuilders, varying quality.

Brake Master Cylinder

BMC 400 S

Lockheed OEM  Sprite/ Midget (1967-on) brake master cylinder 

This OEM part may leak after driving a few miles.
Carb Float

CBF 100 T6 and others

 Zenith OEM. Used in most Zenith Stromberg carbs  These floats fill with gas and sink in the float chamber after a few miles. Gas-type related?

Clutch Master Cylinder

CMC 300 S

Lockheed OEM reproduction Sprite/ Midget (1966-on) clutch master cylinder

You will know this master cylinder because it has a plastic reservoir. The reservoir is too large and hits the bonnet.

Condensor

CND 100 B

Lucas OEM MGB (1963-74) condenser, Fits many British cars.

Some fail from new or after a few miles of use. The car will run terribly.

Clutch Release Bearing

CTC 120 T6

OEM Borg & Beck or Green clutch release bearing for TR6

Some release bearings start to whine after a few miles of use.
Mufflers

EXH 210B & EXH 310 B

 Walker muffler's for MGB's, other brands, too These mufflers are bent in the wrong places and are hard to fit. Need to heat and rebend them yourself.
Muffler Straps

EXB 117 B

1963-1974.5

 Rear Muffler Straps Only late ones available which are too big for early muffler

Fuel Sending Unit

FSU

Any repro fuel sending unit for any British car

Most repro's are poorly made and badly calibrated.
Front Grille

GRL 100 B

 1962- 1969 MGB grille These reproductions are made poorly and wont fit unless you beat on them and bend them.
Gulp Valve

GPV 100 B,S

Reproduction Gulp Valve

for MGB and Sprite/ Midget

 Poorly made, die prematurely
Head Gasket

HDG 400 S

 All Head gaskets for 1500's, Midget's (75-on) and Spitfires (74-on) Match head gasket to block for cylinder rings, or risk leak.

Lay Shaft

LST 200 B

Reproduction lay shaft for MGB's with all synchro transmission

Shaft diameter is too large.

Lay Shaft

LST 200 P

Reproduction lay shaft for Spitfires (1971-on) and GT6.

This reproduction is not properly hardened and fails after a few miles of use. When it fails it ruins other parts within the gearbox.
Manual Choke Conversion Manual choke conversion made for Zenith Stromberg's that originally came with the automatic water choke We do not recommend these as we feel that a properly maintained auto choke works best. If the choke is serviced as per workshop manual recommendations, it will work correctly.
New SU Carbs Various models Most new SU carbs need modification.  We recommend properly rebuilding your original carburettor(s).
Oil Flex Line  Oil pressure line from engine to oil gauge These repro lines have a steel sleeve but inside have a poor quality rubber hose which leaks. Within a few minutes, your motor could run dry. We make our own here.

Oil Pump

OLP 100 S

AE OEM oil pump for Sprite/ Midget (1958-66)

This pump is too large and needs machining to be able to fit

Oil Pump

OLP 200 B

 AE OEM oil pump for 5 main bearing MGB's Some of these oil pumps suffers from poor fit, bad tolerances, and mismachining.
Points

PTS 200 B

Rotor

ROT 100 T6

 Lucas OEM distributor rotor for TR6 Some fail after a few miles of use
Shocks Remanufactured lever shocks for various cars Several companies remanufacture the original lever shocks. We believe that the best rebuilt ones are by Roadstar Nelson.  Even these need to be checked.
Sun Visor

SVR 100LB,S

SVR 100RB,S

 Reproduction sun visors for MGB's and Sprite/ Midget The threaded part of these reproductions is made too short.  The holders on the windshield must be drilled.
Timing Gear

TMG 210 T6

 Timing Gear, Crankshaft Reproduction gear. Woodruff key slot is machined off center so timing is incorrect.
Convertible Top

TOP 250 T6

 Robbins TR6 (1969-on) convertible top The pattern of some of these tops is cut too short.
Tube Shocks Any tube shock conversion kit These cars were not designed for the stresses that these kits introduce on the cars parts.
Turn Signal Switch

TSS 300 B and others

 Reproduction  column turn signal switches for MGB and Midget (1968-80) White box, made in Taiwan. All of these fail. The contacts are substandard and the plastic melts. We try to sell only Lucas switches.

 Reproduction voltage regulators These non- Lucas reproductions are poorly made and fail.
Water Pump for 75- Up MGB
