Includes appropriate bearing sets

*Note: Long and short backed refer to the depth of the rear oil seal surface. Having removed the flywheel and any spacers, if the end of the crank is flush with the engine back plate, it is a short backed crank. If almost an inch of
crankshaft stands proud, a long backed crank is fitted. The flywheel design differs accordingly, i.e. long back cranks use a recessed flywheel, short backs a non recessed flywheel. A short back crank may be used to replace a long back item, but only if the flywheel is swapped for the later version as well.

Before ordering, it would be a worthwhile exercise to check which version is fitted to your vehicle. It is possible that the crank type may have been changed during a previous engine rebuild.

All engine no. CP (150 bhp ).

The installation of a "150 bhp" camshaft in place of a "125 bhp" item does not give an instant performance increase. Other items such as the cylinder head, metering unit & the distributor must be replaced and/or adjusted.

The original CP camshaft had 2 rings in the front journal.

This re manufactured part has 3 rings in the front journal and is a suitable replacement for the original.
Qty Req-1, Model-TR5, Item Info 2-2 rings on front journal

It is vital that a camshaft & its followers are properly lubricated when installed
and run in an engine for the first time.
Use ‘Cam Lube’ (RX1358)

This is the larger diameter follower at 800" OD.

This crankshaft bolt is an essential component for the Triumph TR5, TR250, and TR6 models, specifically designed to secure the crankshaft pulley and hub to the crankshaft. This bolt plays a critical role in ensuring the proper function and alignment of the engine’s rotating assembly.

Key Specifications:
Length: 103mm, measured from under the head of the bolt.

Compatibility: Suitable for Triumph TR5, TR250, and TR6 models across various engine configurations, including those with carburetors and fuel injection systems.

Function: Secures the crankshaft hub extension (Part No. 148831) and the pulley to the crankshaft, preventing movement and ensuring stability during engine operation.

Features:
Material: Manufactured to meet OEM standards, ensuring durability and resistance to the high stresses encountered in engine operation.

Finish: Typically comes with a corrosion-resistant coating to protect against rust and wear, crucial for long-term reliability in classic car restorations.

Direct Fit: This bolt is a direct replacement for the original part, ensuring easy installation without the need for modifications.

Note:
Certain North American market carburetter-engined TR6s had a fan belt that was 1/2" wide in place of the 3/8" wide belt fitted to all TR6 P.I. models. The associated pulleys that the 1/2" fan belt ran with were also wider (which in turn means that the fixed pulley water pumps were also different). To this end, an owner must check the width of the belt and pulley system on his or her car prior to ordering replacement parts, if there is any doubt regarding the originality of the specification of the engine.
