This is the lower vertical bevel gear, fitted to all SOHC International and Manx engines and also fitted to earlier DOHC Manx engines. These gears faithfully replicate the original Norton tooth profile and pattern and we have them made for us by a top specialist UK gear manufacturer.

Price is Each. 

Because these have been made with the original (and correct) Norton bevel gear profile, they can be used in conjunction with original Norton crankshaft bevel gears (unlike some other pattern SOHC gears made in past years by others, that required they were always changed in pairs).  However, if required, we also sell the corresponding crankshaft gear in either International (Item 0422) or SOHC Manx (Item 0423) configuration.

Photograph 1 shows the gear from different angles. Photograph 2 shows an original Norton gear on the left, and our gear on the right, as a comparison. Photograph 3 shows the gear fitted to one of our lower bevel gear housings. The gear has our PVN branding etched on the shaft.

Final point - for anyone building a SOHC Norton engine for the first time - shimming the crankshaft and bevel gears is one of the most important tasks to undertake correctly to ensure it results in a reliable and healthy engine.  Although not complex (compared to some modern engines), it needs to be undertaken in a specific order - and some elements of this process can be fiddly and time consuming . . . but it is definitely worth spending that time to get it right.  If you are not sure how to do this (and what parts it helps to have to make this task more efficient), then email us on sales@racingvincent.co.uk and we will try and offer technical advice
