Part Replacement Tips

In this entry, we’d like to cover information about adding a new replacement part into, what could be, a worn assembly.

Some parts wear faster than others and some parts are designed to be the “weak link” to prevent a high-cost or reckless-break from happening. When replacing a component part, these tips apply no matter how large or how insignificant.

Clean, clean, clean.

A clean surface makes any part fit better and reveals problems that may keep you from being able to correctly assemble sub-components

Have the right tools.

Using the proper tool for the job protects the part and, more importantly, you.

Never force the part.

We use a series of gauges, mandrels, and calibrated tools to ensure the accuracy of every part. On many orders, we’ll ship parts fully-assembled.

If you have to force mating parts to fit together, something is wrong. Remove the new part, check the old part, and try again.

Rework the mating parts.

If setting a new gear ring into an old head, or against an old retainer, check first for sharp edges, burrs, gouges, or wear marks on the parts that aren’t being replaced. Often times, a sharp edge can dig into the mating part and cause a binding effect that (can) damage(s) the new part.

This works with a glue wheel, a bearing, and most parts that turn.

New parts, new bolts.

Be sure worn bolts aren’t being re-used. These can break and create a safety issue. We can even provide the bolts to you if requested, and most do ship with the necessary pins, bolts, or setscrews.

If you’re worried about having the correct length of bolt, let us know. Most damage to the glue wheel, glue shoe, and glue shoe mounting plate comes from someone choosing the wrong bolt.

Tighten, but not too tight.

We have a certified dead-lifter on staff, so we know there are times when a part is tightened beyond the might of two mortal men. In an assembly, an over-tightened bolt can pull parts out of alignment. Snug the bolts into position, check the assembly, and then tighten.

Helpful tip: Stagger the bolts as you tighten, rather than going in a clockwise or counterclockwise direction around the assembly. Tighten North-South-East-West, then the bolts in-between, and you’ll often achieve a better fit.

Check by hand before checking with power.

Always. Though most of our parts are machined to precise fits, the parts meant to turn will always turn by-hand when fitted accurately. If they don’t turn freely, please don’t rely on the machine to “force” the parts to turn.

Be safe.

On any Gartech product–and on any product from another vendor–work safely. If you’re unsure of a fit, unsure if a part is worn, or need some help troubleshooting, feel free to ask us.

E-mailing a picture of the part can save a lot of headaches, too.
