Following on from video #1410, this covers the rebuild and bench testing of a starter motor from a 1992 Nissan Patrol GR 4.2 diesel. On the previous video #1410 where we stripped down and completed both electrical tests and mechanical inspections on all internal components of the unit.
Years ago it was common for garages to strip and repair starter motors, though more recently, due to falling unit prices and rising labour costs, its become more common to just fit a new unit and not even 'bother' to take a look inside.
Given the cost of a new starter for one of these larger 4x4 type vehicles it is still a viable option to strip & inspect this unit with a view to undertaking a repair, especially given the cost of a new starter for this Patrol is around $600!!
Individual service parts including brush packs, solenoids, one way clutches and even bearings are still easily sourced and relatively cheap. Combine this with doing the inspection/rebuild yourself and you'll save a ton of labour costs too, which makes this option totally viable.
This video covers the rebuild, step by step, including helpful hints and 'as you go testing' to ensure the unit is fully operational once assembled.
Specifications & an exploded component diagram are also included.
To preform the rebuild & bench tests you'll need a handful of common tools plus a car battery & a set of jump leads.
If you have any questions or comments then just ask away & I'll do my best to help. I won't be able to provide you with any specific specifications for your car's starter motor as they are all different. However, after around an hour of searching on the internet I found a PDF of Nissan's manual for this Patrol so I'm confident you'll be able to do the same most likely. Worst case you will be able to purchase one for around $10 to $15 from many of the Workshop manual web sites around.
Its probably best to obtain a copy of the manual before you make a start, that way you'll also know the best way to take your car's starter motor apart.
