Polaris Head Bolt Thread Repair Kit - Information and Recommended Kit & Inserts

Polaris Head Bolt Thread Repair Kit - Information and Recommended Kit & Inserts

Aluminum head bolt threads pulling out on Polaris engines is a fairly common problem. Installing a solid bushing-type steel insert is the best fix. Avoiding the expense of some of the larger kits designed for automotive applications is a smart way to save money and still get a quality repair. The larger Time-Sert kits, for example, are designed for doing repairs when the threads start down several inches. With threads flush or near the surface, a much less expensive kit made by Time-Sert can be used effectively. Longer inserts can be used with the 1112 small kit. The kit comes with 22mm length inserts; however, the 30mm length inserts make more sense, especially with part number 11127, as they provide more threads and are the same inserts provided in the much more expensive kit, part number 11125.

It's important to know that the 1112 kit is for a first-time repair when no other repair has been used previously, making the hole larger than normal. If a previous repair has been used, like the Heli-Coil or a similar brand, an oversize kit would be needed. Big-Sert is Time-Sert's line of oversize repair kits and inserts that can be used for second-time repairs and still accept the original size bolts.
